generally with those small hand winches you have a lever to disengage the drive so you can free spool out the wire quick. maybe that's missing.

I'd just put some spacers in there to remove the play personally.

there's NO method to disengage the worm, lever OR otherwise. yeah, I'm thinking of either installing some brass spacers (I'd need to make), along with -maybe- a thrust bearing (like from a small car scissor jack) at the correct end, and the brass spacer at the opposite end of the worm. thanks :-)

it looks like an old home made farm winch or boat winch, so must have been made with spare parts, so that worm gear is sliding up and down the keyway and shaft because it probably wasnt made for it, or was just tac welded into the center of that gap. I would suggest just welding it fully, back into the best fitting, most contact area with spur gear position.

@jmcclusk yeah, I think you could be right; I think maybe this thing had something to do with either chicken farm, or old storefront crank-out awnings, or like that. maybe it WAS a boat trailer winch. whatever it's from originally, I like that the the main gear is SOLID, not made from 'laminated and riveted plates' like the current ones.

other than the 'flat bar' crosspiece being welded to the outer frame, there are -no- welds on this thing (excluding, possibly, the spool being a weldment).

@jmcclusk the worm -itself- seems well 'fixed' to the shaft - just the 'shaft assembly WITH the worm' that moves too far "end to end".

this thing IS a bit hard to figure out, in some respects, though: it has better quality gears than most, but the worm SHAFT bears "steel shaft inside a plain steel bore" at one end, and the other end of same shaft runs in a flanged STEEL bushing (which is weird). why the factory didn't use a brass bushing, or oillite type there, I have no clue...thanks :-)

Looked like there is a grove cut in the end to take an external snap ring, that would hold the worm gear all the way to the bottom and hot let it walk up.

@hardwares1 mcmaster.com measure it their parts book is huge, you may find your brass spacer in there. you may find a machine shop to cut you two pieces of pipe for less than 20$

is there any holes for set screws or a rollpin in the shaft or collars looks like the crank end of the shaft is held on with a setscrew

[NathansBackwoods]

Your trust bearings are out of place and or worn out, remount a new set of bearings and the shaft wont slide.

now there's yer problem :P

@hardwares1 hi mate, think I was drunk when I replied, looking at it now there's obviously no way to disengage the worm!! DOH!!

Looking at it sobber, the only reason I can think the worm moves on the shaft was there may have been some rubber spacers that would have been there to stop any shock loading on the winch.

Sounds like a good plan with the spacers

@pfuntner

the worm -is- there, clearly, and also undamaged, including both of its ends...thanks :-/
