In addition to those questions, there is a collar just in front of that baring. Do you straighten out the locking spline and unscrew that to remove? Is there a special tool to unscrew the collar?Where did you get standard circlips to substitute them? What retailer carries them?
Last question - how do you approach sizing?
I agree, circlips are much more civilized than those things.

Yes, Cat in their infinite wisdom thought this a good idea. Being the frugal snowmobiler I am. I made a spanner socket out of some key stock and a deep well socket, welded it up . Since it required torqueing upon reassembly is why the socket. In 2016 Yamaha, not sure about Cat, went back to a better way. 2016 and newer use standard circlips. Dont know if its a direct replacement - retrofit to the old ones though.In addition to those questions, there is a collar just in front of that baring.

EDIT: It almost looks like a spanner wrench is required, but I have never seen one that will go deep enough into the casing to lock in and have swing room for the handle. Any input? Is a spanner wrench required for this?
I read darn near every post on the subject. I am going with FAG and NTN bearing replacement bearings due to to those posts. Questions asked here have not been answered to the best of my knowledge.

If you are referring to the bearings my recommendation is to update to 16 or 17 parts including jackshaft or just use stock. I got 7000mi out of mine and they were still good as New when replaced. If you use another source for bearings and you keep the retainer and nut be sure the upper Jackshaft bearing in case has a tapered inner race to match original.I read darn near every post on the subject.
