Lubrication on the “gears” under the slides

LIP sheet tells what oil to use. Use German torque!!!

Lubrication of Gear Pack

Michael,

Nice to hear from the horse's mouth....thank you, sir! :-)

From Michael's post;
NOTE: Do not lubricate rack or pinion gear
teeth. Lubricate drive shaft only.

Thanks Michael, I hadn't seen that sheet.

For the past 5 years, I've used the Walmart brand of spray silicone that comes in the red can, costs $1.99 per can. It works just fine and does not attract dirt or grime.

works great

I have spottt rust on rails, any recommendations? Also does amyone spray the the whole underside? Or what about the nylon piece inside the 5th wheel?

I know that after I clean and lube my slide gears and pistons they retract and extend smoother and easier. Just a personal observation and preference.

yes they do

I usually wait to lube ours until they get a bit jumpy when moving. Lubing them smooths it out. Keystone Service Center said to lube them. But Lippert build them, so who knows. I don't know who is right. I just play it by ear and if they get jumpy they get lubed. Seems to me anything with metal to metal contact during movement ought to be lubed somehow.

are those guys fulltimers in the salt and nooks and crannies

ok when you say drive shaft do you the hydralic drive shaft? No Dumb question right

Go to this and it explains where to lube. I do use a dry teflon spray in the sides of the large tubes which helps the slides run smoother

Pugtracker, I'm not sure what you're asking. Sorry. If you mean are the Keystone people fulltimers, I doubt it but don't really know. They do know what works with their products and what doesn't, though, since they see the results. If you mean are we fulltimers, the answer is yes. If you meant something else, please clarify for me and I'll try to answer if I can.

I was not aware of that but will avoid lubing the gearpack in the future. Just the rack. I wonder what harm it causes to spray lube into the gear pack. I know it won't lube the entire pack unless you move the slide while lubing but that's a different issue.

--on edit-- after looking at Michael's link it appears the gear pack should be lubed if it gets "squeaky" but with synthetic motor oil, not with dry lube.

And there's no reason, apparently, to shoot any kind of lube onto the teeth of the gearpack. Just dry lube the teeth on the rack. I don't see where dry lube on the gearpack teeth would hurt anything, though, and it seems to me that lubing those teeth as well as the rack teeth would reduce the potential of unlubed metal to metal contact. I guess this is why those guys get the big bucks and I don't.

Steve,

While the LIP sheet states to use Mobil 1 oil on the GEAR PACK points and nothing on the rack and pinion, some of the techs at Lippert have sprayed a dry lubricant on the gear pack points as a quick fix. I think the point is that nothing should be put on the rack and pinion especially because the rack touches the carpet as it extends and retracts...

I do put rust inhibiting lubricant on the piston to help keep pitting from forming.

On our unit the rack gears re-track into a channel under the floor. I can't visualize them going inside the RV above the carpet, as the racks support the slide room.

I routinely clean the racks, and lube with silicone. I also lube the shafts in the gear packs per Lippert recommendations.

[Recumbent]

As is recommended by Lippert there is no reason to ever lub the teeth, just keep them clean. The shaft that turns is the only place to lub. You could extend and retract the slides umpteen times a day and not wearout the teeth in the round and flat cogs.

What causes the jumpy motion that seems to be relieved when dry lubing the rack? It just doesn't make sense to me to not lube metal to metal contact. But Lippert ought to know. Still, I have to wonder why mine gets jumpy when it needs lubrication? Our last two Montanas have been this way. The first of the three had the cable system so this conversation is not relevant to it.

Steve, I actually lube the sides and top of the rack with silicone. The channel on ours has small pads that take the wear of the racks running in and out. I have found that lube helps smooth the operation of the slides. The inner end of the rack has a nylon roller. I sure wouldn't advise anyone to use grease or oil on the racks tho... too much chance of dirt and grit collecting. I really think Lippert saying not to lube the racks is probably another CYA statement....better dry than tons of grease or oil!

I misspoke about the carpet - I was looking at where we get wear on the carpet and slipped and made an incorrect comment. Sorry!

Our slide clears the floor (used to be carpet)by probably an inch. Wonder if your slide might need adjusted? I know I had to raise one end of ours.... way out of level.
