YMM-45 MMM Spindle assemblies.

[Rcpilot82]

I am trying to put together my YMM-45 deck that was tore apart by someone else. They had the 2 outboard spindles in pieces to re-build them. I have the new bearings and all but 2 seals (working on that). I blasted all the parts and will probably just powdercoat them for durability.

Now, The problem is I don't have any exploded views or information on how to re-assemble the spindles. Does anyone have any information on this and recommended pre-load procedure for the tapered bearings? I also am going to need a locknut for the middle blade as the heat required to break it loose melted the nylon.

Any Help would be great!

Winston, yes I know Gary as well. I got an air cleaner housing off him a few weeks ago. I think I have all the parts I need though, just need to see how to approach the re-assembly and if there are any special issues to address. I'll shoot him an e-mail anyway.

I hope this helps

That helps! is there a procedure for pre-loading the tapered bearings?

Also do you know what #23 is the first pic?

The manual calls it a 'cup washer -5/8'

is there a procedure for pre-loading the tapered bearings?

It does not mention anything in the manual. I would just set them like a trailer axle tapered bearing which is usually: Tighten the nuts fully tight, rotate the spindle a few times in each direction to be sure everything is seated, loosen the nut completely, then re-tighten just beyond finger tight.

Thanks for the Information! I also just received information from Gary so I hopefully will be good to go.

Did Gary have any advice on preload?

 

[Rcpilot82]

No, there doesn't seem to be any specifics on that so I'll just use the method above. It looks like the only thing I am going to need is a new locknut that holds the spindle in. Item 9 on the spindle. Should be able to find that locally once I get the size.

Take the spindle with you to try the nuts.
