Power Gear Slide Motor Removal & Installation Questions
The gearbox of my Power Gear slide motor is seeping oil. It is my understanding that the oil is a byproduct of the grease inside the gearbox separating into its components.
My first thought was to check the tightness of the screws holding the gearbox cover halves together. Not all of those screws are accessible while the motor is mounted, but those I could get to were all loose.
I tightened the loose screws and wiped the gearbox clean of the oil that had seeped onto its cover several months ago. I checked the gearbox cover again a few days ago and it was apparent it was still seeping oil. It may be from the gasket and/or the seals through which the drive shaft passes.
I figure a good next step might be to remove the motor, check and tighten all screws if need be, wipe down the gearbox, reinstall, and check for seeping oil again in the near future.
This brings me to my questions which have to do with removing and reinstalling the motor. I can see that the motor/gearbox assembly is attached to a bracket with 4 bolts which would need to be removed in order to dismount the motor. According to what I’ve read there may be more to it than just removing those bolts. I’ve come across mention of roll pins and sheer pins.
I’m attaching two photos: one shows, from left to right, the rack and pinion gear, a housing that sits between the rack and pinion and gear box through which the drive shaft passes and seems to have a roll pin, the gearbox and motor. The second photo is a close-up of the housing with the roll pin.
Will I have to remove the roll pin in order to remove the motor? If so, should I expect to tap it out part way with a hammer and drift, then rotate the drive shaft 180º and pull the pin out with a pliers? Would I even be able to rotate the shaft with the pin when it's pushed out part way or would the pin hit the surrounding metal when rotating the shaft and screw things up?
When reassembling will I need to have a new roll pin or will I be able to reuse the one that’s in use now? If I’ll need a new one where would I look for that? Can I determine it’s size with my micrometer?
I’ve come across info that says to roll the slide room in about 6” in order to take the weight off of something in order to pull the motor. Anybody know anything about that?
If I open the gearbox is anything going to fall out that I might have difficulty putting together correctly?
Lippert says there are no parts available separately for my motor/gearbox. If I open the gearbox I won’t be able to get a new gasket for reassembly. Will one of the liquid gasket products do the trick?
Does anybody know about replacing the seals on the shafts exiting the gearbox in terms of the size and kinds of seals and methodology?
What would be the right kind of grease to use when repacking the gearbox?
What else do I need to know in order to pull off this operation?
BTW, it’s about $1200 for a new motor/gearbox assembly from Lippert which explains why I’m so keen on avoiding that option. I have found no aftermarket parts available for what Lippert has told me is a part number 672037.
If you can answer any of my questions I’d appreciate hearing from you.
Thanks much.
