Power Gear Slide adjustments

[wonsquire]

I have a 2000 Knight 36Z, with the long galley/couch drivers side slideout. I am having an issue with shearing roll pins in the drive gears and occasionally a bolt on the drive shaft. I have learned how to "synchronize" the slide, which I'm sure was previously an issue.
I also found Power Gears offerings for adjustments. I found the front, (drivers) end was slightly low on the outter end, I had to raise the slide box slightly in order to achieve the required neutral to slightly positive measurement as it relates to the inner measurement on the rack. Now the bottom front corner doesn't pull in completely when I close the slide. It also sheared another bolt. So, I'm looking for suggestions here because I appear to be missing something.
The other concern is the rollers that are covered by the plastic boxes. One is in the L.F. fender well and the others are inside the storage bins. I am given to understand that this isn't Power Gears but something added by Monaco. Due to the vintage of my rig the factory was unable to provide any information on this. Could someone please tell me what Monaco had in mind when they added these rollers, and, how to properly set/adjust them?
I would think that there is a proper sequence to all of these adjustments in order to get this thing back on track. (Pun intended)
Thanks for your help!

My electric slide motor does not turn the shafts going out to the gear drives. Don't know if something inside the motor has been sheared. Slide is pinching in at the rear and has a gap at the front. Closed the slide by using a pipe wrench on the shafts. Holding it closed with the wrench. Need to move the coach but afraid to.

I'm going to guess that our slides are similar from what you described.
1. Does the slide motor run? If it does there is a round output shaft that protrudes fore and aft, if they don't rotate when you run the motor, your gearbox is most likely bad.
2. The drive shafts, square tubing, one fore-one aft, are attached at each end with a 1/4" bolt. These bolts will shear. Check your bolts.
3. There is a roll/shear pin in each gear, again if yours is like mine, one fore-one aft. (Drives the rack gear) These also can/will shear.
4. If you have a malfunctioning slide topper awning it can be contributing to your slide issues.
5. Your rig may or may not have slide locks that are used when in travel mode. (Normally installed from inside the cabin) If you can put these in place, you should be safe to travel.
6. There may also be a lever on the slide motor/ gearbox that engages-disengages the brake. Used to manually override the motor when there is a motor or gearbox failure. Check your manual to make sure it's positioned properly.
Hope this helps...
