I spoke with Jack last week. He can’t get new motors right now from his usual distributor citing supply chain issues. Not that the information is helpful, but you might want to just focus on repairing what is broken for now.

Some time ago someone posted what the Wilhelmson nose lift motor/gearbox came from so as to get repair parts.

My EZ-Noselift is making clunk noises like a tooth is missing off the gear. I’m about to pull it apart and look for replacement items. On the plus side, It’s been operating for over 13 years and 850 hours trouble free.

Anyone know what the motor/gear box came from? I’m thinking a trailer lounge lift.

Thanks

Pull the lid off the motor, its EZ, and you can see the gears. I think you'll find the gears are fine and the clunking noise is below the motor in the part Jack makes. If so its probably a bad bearing and these can be sourced from any bearing supplier. Suggest a you get them from Motion industries, Applied industrial or similar and not Amazon or Ebay.
These are a tapered bearing set and there really is no means to adjust the preload. If its not close you’ll have to shim or machine something, or send it to Jack. I’ll bet it comes in pretty close and you wont have a problem.

Thanks Tim/Izzy,

I’ll be pulling it apart over the next few days.  I’ll let the group know what I find.

I’ve pulled it apart and the bearings are on the rough side.  I’m about to pick up new ones locally.

Is the worm drive something I should be pulling apart and servicing while I’m here?  Also the spring?  I’ve got a bit of wear on the alignment slot.

I would take it apart a bit more and replace the set-screw that is chewing up the gold-anodized part.  The set-screws probably use Loctite so they will need to be heated to remove them.  (see pic below) There is a recirculating-ball mechanism/nut that probably just needs wiping off and regreasing.  The recirculating nut has a bunch of tiny balls inside that can be removed but be careful to catch them.  They are a little tedious to reinsert, too.  Probably not necessary to disassemble the nut.

Mine did the same thing on that slot. Jack didn't think it hurts anything. 

As suggested Id clean and grease it. 

Jack might tell you what type grease to use, my only concern is not all grease types play well together and you probably cant get all of it out without further disassembly. 

Where the bearings still intact? Cage not damaged no spalling of the races? (The inner race, under the rollers is typically the first place to fail and hardest to inspect)
