I counted 5 washers still on the shaft...gear is awfully centered for needle bearings to be gone.

Looked like a wheel touch down. I'd disassemble that sc/shaft and start counting. See if you can't account for all the missing pieces...otherwise...if you can't...then it'll be time to start some major cleaning.

now..the diff in pics between yours and mine ....the space between your washers...and the shaft on mine showing misalignment because the top bearings all rolled to one side.

Point being...you still have 5 washers on your sc shaft.

So...if the shop mech is telling you things are missing...when they ain't.....I'd have a bit of a prob with that.

hjgreg and joez' s assessment was right on the money.

 

[davidrxp]

So what am I missing exactly?

So what am I missing exactly?

That's what I'm trying to tell you...take it apart and find out.

If it's top bearing cage...see if you can't account for all the pieces...7 ball bearings(from the busted top cage) too. My bet...all 40 needle bearings are still in place.

Lemme show you what I found in mine which led me to feel comfortable in not having to go through the motor...just a sec...

Can you make all my needle bearings/...fused to the inside of my gear? one broken washer...and 99.5% of the top bearing cage. If I hadn't found everything still on the shaft...I'da have gone through the pump screens at the barest minimum...but splitting the cases is not unheard of.

Like as I'm sure been said...simply replacing the sc assembly...after an incident like this...is not completing the repair.

You are missing your ceramic slip washers which are in your motor now, or at least your pto housing in a bunch of pieces. Look at the picture below that is not missing the slip washers. On each side of the gear are the slip washers which are gold in color, hardened steel in this case. On your picture, do you see the gap where the gear can slide back and forth because the washers are completely gone? This is a problem but may not be the only problem. The needle bearings look to be in place(because the gear still centered) still and generally don't get lost. Your bearings or plastic bearing carrier may be bad as well. The 5 washers on the end are the spring disc washers that are cone shaped and apply pressure to the gear from slipping by "pinching" it.

ski-doo,

Curious...in your pic showing gold clutch washers....why is there gaps in between the spring washers?..not torqued yet?

 

[ski-d00]

No, actually the gear is worn on each side so there is no longer any spring pressure. I stole this pic from the another forum post where the washers ate the gear up which happens when they wear out. Not sure if I'm allowed to post a link but is a nice tech article showing what things look like with multiple pics when metal washers wear out which is much better than losing your ceramic washers in your motor.

10-4. Makes me wonder why the gear lost mass instead of the washers? Someone just doing washer swaps instead of full rebuilds?

 

[ski-d00]

No, the washers are harder than the gear so the gear wears some every time there is slippage. It's designed this way because if they were equal hardness they would eat each other up quickly and is typical of sliding bearing surfaces and all clutches.

Thanks for this info guys I will show my mechanic friend.
Also we intend & ate in the process if lOokong at the motor I already said that on here over times. When I know I will tell/show.
