Open Roads Forum  >  Tech Issues  > BAL Accu-Slide maxed out on adjustment Reply to Topic  |  Subscribe  |  Print Topic  |  Post New Topic  |  Oldest first Newest first  Page of 2   Next JBarca • View posts Radnor, Ohio, USA Senior Member Joined: 12/16/2004 View Profile Offline Posted: 01/31/23 06:53pm Link  |  Quote  |  Print  |  Notify Moderator I have two questions dealing with a BAL cable Accu-Slide system. The two questions are below. I am trying to give you the background on the camper. The camper is a 2019 Keystone Laredo 5th wheel, Model 255SRL. It was bought new in Dec 2019; with the Covid issues, the camper has only been used three camping seasons with light to moderate use. The camper is a friend's who I'm doing some repair/service work on. I noticed the main dinette/fridge slide was not working right, it jerked when it went out and in, and there was a sagging cable outside. Upon investigation, the cable tensioning hardware was loose inside. The adjustments I have made after seeing the issues are the first time anyone has adjusted this slide since it was bought. I'm unsure if the factory did not tighten the cable block jam nuts or if they vibrated loose from towing. The smaller bedroom slide also has loose hardware but is not far from adjustment. The main slide was very far out of adjustment and is many times heavier. Here are pictures as found. The sagging cable on the top front. The motor drive area shows loose jam nuts and cable tension blocks on an angle. It is hard to see the jam nuts, but they are loose. The rear "out" cable yoke/block with loose cables. This is with the slide fully retracted. Note the center chain tension bolt is maxed out. The front "out" cable block with the block on an angle. They are supposed to be vertical. An inside view of the slide The "inside" bottom of the slide room flanges were not touching when the slide was fully out. The rear inside bottom slide room flange had a 1 1/4" gap. The front inside bottom slide room flange had a 3/4" gap. The tops of the front and the rear inside flange touched the wall flange. This large gap shows the "out" cables are loose from where they are supposed to be and why the slide jerked when the motor started until all the slack tightened up. NOTE: The drive chain distance from the center of the motor sprocket was even on both sides of the front and rear chains to the cable blocks. This was correct from the factory. I read all the online BAL service manuals and saw the videos. BAL did a good job on this. However, they did not drill into what I am seeing now. I am seeking help if anyone has seen and dealt with this before. Question 1. I'm questioning how tight the OUT cables must be to pull the bottom of the slide up against the wall? Or do they not have the bottom touch on a large, fully loaded slide room? BAL states the bottom is to touch. I used a floor jack to level/lighten the slide, so the inside flanges were even top and bottom, front and rear, and tightened the cables to the 1/2" finger squeeze pressure adjustment. When I released the jack pressure, the OUT tension was not enough, and the bottom of the slide moved away from the wall. I have adjusted in place with full slide load the OUT blocks, but the tension on the cables and chain is banjo tight, and I'm still 1/2" away at the bottom on both ends. I have more room to adjust, but I wanted to ask before cranking some more. The tension on the bearings in that gearbox seems immense. The way the system was, there was not enough adjustment left on the OUT cable blocks to adjust the bottom of the slide to be pulled into place. I moved the chain 9 links. Yes, that much. This much of a need to move the chain to get the OUT top to come close sort of points to the factory may not have had the bottom of the slide flanges touch as shipped. Here are pic's as I left them tonight. You can see I still have room to adjust the OUT blocks, and the slide is up to the wall at the top, but the bottom is out 1/2". The jam nuts are not yet tightened, as I am still working through this adjustment process. The rear OUT chain block The front OUT chain block Here is the 1/2" gap at the bottom after my last adjustment At the bottom, the green tape is where the cable is attached. I use green tape to measure in the same place while adjusting. The top touching the wall. The floor jack setup I used when I unhooked the chains to adjust and even out the slide to start the tensioning. Question 2: This topic is not mentioned in any service manuals. The way this system is at the moment, there is not enough adjustment left on the "IN" chain blocks. It appears the cable length was wrong, the cable and/or chain stretched, but no adjustment is left to create tension on the IN cable blocks. The question is, in this case, do I remove chain links? Ideally, I need 1" to 1 1/4" inches of chain on both chains removed to get back into the middle of the adjustment. It is hard for me to believe the cable pulley bushings are heavily worn in the three years of use; heavy pulley bushing wear could cause some of this. I am not sure the factory ever had the bottom of the slide tight to the wall. Either the crimped cable end on the outside flange brackets was in the wrong location at the factory, or the chain was too long. I'm unsure if the cables come pre-crimped from BAL or if the installer crimps them. The Rear OUT block was maxed on adjustment, as seen in the as found pics. Keystone used all the adjustments available on the rear OUT block on day one. This makes me suspicious of how the system was adjusted when shipped. Here are pics where the IN chain blocks as I left it. The IN cables are not yet tensioned, and there is still some slack in the system. There is no more adjustment left. The rear IN block as I left it The front IN block as I left it Recapping my two questions: No. 1 I'm questioning how tight the OUT cables must be to pull the bottom of the slide up against the wall? Or do they not have the bottom touch on a large, fully loaded slide room? What distance is acceptable? No. 2: Do I remove chain links to gain more IN adjustment? Or do something else? Thanks for any help. I have sent a message to BAL tech support, but they have not yet returned the call. Hoping this is not the first time this has happened Thanks John PS. I have adjusted many LCI rack and pinion electric slide drives, flush floor and above the floor, the older Dewald/Power Gear rack and pinion, and the old Barker rack and pinion system. This is, however, my first cable slide to work on. * This post was last edited 01/31/23 10:25pm by JBarca *   View edit history John & Cindy 2005 Ford F350 Super Duty, 4x4; 6.8L V10 with 4.10 CC, SB, Lariat & FX4 package 21,000 GCWR, 11,000 GVWR Ford Tow Command 1,700# Reese HP hitch & HP Dual Cam 2 1/2" Towbeast Receiver 2004 Sunline Solaris T310SR (I wish we were camping!)

Are you supposed to actually read those instructions on those multi colored stickers? I'm sorry I can't offer any advice. I do think that your idea of maybe adjusting the chain links on the sprockets might get you more adjustment in the cables. I guess cables stretch, so maybe that's what's happened over the last several years? So glad my slide looks to be a rack and pinion setup on the big slide and those 'gear' things on the little front slide.. Great shop to be able to work on it all however! Dang.. That's awesome!

Look up "BAL 22305 Cable Repair Kit Accuslide". There are plenty of videos on youtube showing how to do it. Aside from the kit you will need cable cutters and a swaging tool. I wouldn't move the chains without actually talking to BAL. You don't want to run the sprocket out of chain and cause a bind. Unless the sprockets already jumped links you should be able to make the new cables the correct length and get everything in adjustment. If you are not sure of where the chains should be in relation to the slide position, again, I would contact BAL for guidance. 2021 Chevy Silverado LTZ 3500 Diesel 2022 Montana Legacy 3931FB Pull-Rite Super Glide 4500 1995brave • View posts San Antonio, TX Senior Member Joined: 01/24/2006 View Profile Offline Posted: 02/01/23 06:40am Link  |  Quote  |  Print  |  Notify Moderator I have the same BAL Accuslide system on my NEXUS Phantom and the upper and lower cables are tight when the slide is out. I still have adjustment left on both the in and out cables. I did notice when mine is in I have about a half inch space at the bottom while the top is tight. schlep1967 • View posts Harrisburg, PA Senior Member Joined: 12/08/2005 View Profile Good Sam RV Club Member Posted: 02/01/23 06:50am Link  |  Quote  |  Print  |  Notify Moderator Remember this is an 8 cable system 4 that pull out and 4 that pull in. It is a give and take setup. Both sides should be equally tight with about a 1/2 inch of movement on the "loose" side of the cable. I.e. When the slide is in, the cable you can see on the inside is the loose cable. When the slide is out, the cable you can see outside is the loose cable. Nothing should be "banjo tight". opnspaces • View posts San Diego Ca Senior Member Joined: 12/22/2004 View Profile Online Posted: 02/01/23 08:14am Link  |  Quote  |  Print  |  Notify Moderator The only thing I can say is before removing chain links I would try putting a 2" thick stack of washers under each adjustment nut. If it all works then you can remove the washers and cut the chain. If no change you can remove the washers no harm no foul. * This post was edited 02/01/23 09:23am by opnspaces * 2001 Suburban 4x4. 6.0L, 4.10 3/4 ton 2005 Jayco Jay Flight 27BH 1986 Coleman Columbia Popup.

They do help. And a special thanks to schlep1967 and opnspaces. Your posts made me think harder about some areas, and I have made some progress today. The cliff notes version, I will summarize more after this is all over, it is not over yet. I talked with BAL tech service today. What a great group. A breath of fresh air in the manufacturing world for customer support. Very helpful. I told them my situation, and they explained some details. High points:. During the OUT adjustment, the bottom slide flanges are to touch the frame when cables are adjusted properly. I spoke about the tensioning issue and what seemed like an absorbent amount of tension needed, and I was still 1/2" away from the wall on the bottom. He said you are fighting the slide's weight; use a floor jack and remove some of the weight. I explained I tried that but lost the tension when I removed the jack. He stated you have to compensate for the sag and crank more. I did and was able to get the slide bottom in within 1/16" to 1/8". He did say, as a last, absolute last resort, that if you have no more adjustments, you can remove 1" of links only at the IN end of the chain. This is only for special cases if you have one of the on-the-edge odd setups. He did talk about shifting the chain 1 or 2 links on the sprocket to shift some excess adjustment from the OUT cable block to the IN cable block. We talked about cable stretch, chain stretch, and pulley bushing wear. He agreed, on this slide, being this new, with such little use, there should be no heavy wear or stretch. This concluded the call. After the call and thinking about all this, I used the floor jack and jacked the slide slightly high by about 1/4" on the outside wall. This over-jacking kicked the top of the slide in a little. This allowed me to adjust the tension more on the bottom cable and not have to crack so hard. I adjusted the OUT setup, which now can hold the settings under the slide's weight (no jack) with both ends of the slide bottom flange within 1/16" to 1/8" at the top and bottom slide flanges on both ends of the slide. This confirmed I could get the system setup correctly in the OUT direction. However, I still had too much excess chain at the IN chain cable bracket to adjust the IN direction. After I had the OUT set correct, I saw about 1" extra adjustment on the 1/4 - 20 center draw bolt on the OUT cable blocks. I measured where all the OUT cables were located about the ends of the cable threads, put the jack back in place, unhooked the chains, and moved two links backward on the chains. Each link is 3/8". This lost 3/4" adjustment at the OUT blocks and created 3/4" more adjustment at the IN blocks. I still have 1/4" more center bolt adjustment if needed at the OUT blocks. I put all the OUT cables back in tension and proceeded with the IN blocks. I was able to get the IN block adjusted as is. This allowed me to start moving the slide in and out under power. The slide room now moves instantly when the power button is pressed, with no delay in movement; it just goes out and no jerking or on the way in. It took several tweaks and cable adjustment tweaks to get the outside slide seal compressed correctly and have the correct 1/2" lift test tension on all eight cables when they are relaxed. As the system runs, all the trapped cable slack comes out, and you eventually get it all tight with tweaking adjustments. The system is working, but I still have two problems. The rear bottom inside slide flange has about a 1/2" gap. This came after running the slide in and out several times. The front bottom is good. And I am out of cable adjustment on the bottom OUT cable block. My first correction for this is to add a 1" tube spacer made out of 1/8" sch 40 pipe over the 1/4" threads on the OUT BTM block cable. This is from opnspaces comment. This is an easily reversible fix if it does not cure the problem. I can always cut that chain later, but I do not think I will have to. The next problem, I believe, is a gearbox install problem from the factory. Now that the slide is working, I can see the interface problem that has been going on for a long time. The IN and OUT cable blocks crash into the gear motor. The IN block is worse than the OUT block. I will post pics in the next reply on the motor issue. Be back soon.

The IN cable block hit hard; you can hear and see the slide jump twice. The first hit is the adjusting screw nut, followed by the chain cable block. The ground-up motor end cap and the heavy rubs in the motor casing show this has been ongoing for some time. After some digging, I believe the factory mounted the motor too high. This camper has a bedroom wardrobe slide with the same G4 series Accu-slide. The bedroom slide does not hit. It has other adjustments that need to be done, but it does not hit. Reviewing the BAL G4 series install manual, it doe snot state an exact height for the motor. I will call BAL tech service tomorrow and confirm all this. Please comment if anyone has seen this before and knows of a correction. My first thought is the remote motor correctly not to have it hit. Here is the BAL Video showing how to adjust the Accu-slide. https://www.youtube.com/watch?v=dUIW7kkJa5I At minute 4:19 it shows this view of the motor mounted. The cables are more straight, not dead on, but more straight, heading into the gearbox sprocket, showing the cable blocks are missing the motor. The motor is lower to the rough opening in the slide. Here is minute 5:37 in the video with another view; the IN chain side is loose during this adjustment, which is why the chain is hanging down on the backside. Now to the Keystone main slide with the problem. Here is the system as I left it tonight. The rear side of the slide is at the full IN position. The IN block hits the motor. The front side so you can see the whole system. Close-up of the problem. The first part of the hit was the cable screw and nut hit, then the cable bracket. An end view. Look at the chain going towards the front of the slide, and see how downhill that chain is heading. The wear marks on the motor It is a 2 1/2" long drag to the end of the marks. A straight-on view. See how much the wallboard is shown above the black slide seal. This is where I am saying the motor looks to be mounted too high up. And here is the OUT cable block that hits slightly too. It is out of adjustment, and I will try the pipe spacer to give me some more tension adjustment. Now to the bedroom wardrobe slide. Again this slide needs adjustment, but the cable blocks do not hit the motor. The motor is also slightly pitched uphill. The IN cable block misses The OUT block misses. You can see how close the motor is to the rough opening and top slide seal areas. Almost no wallboard is showing, and it is tipped uphill. This is where it stands as of now. The cable hitting the motor has to be corrected, and I need to get some more tension on the OUT cable on the rear bottom of the slide. Any thoughts would be greatly appreciated. John PS I will report back on the BAL tech service call.
