1997 SeaDoo GTX Piston Thrust Washers

[yrn2fly]

Hello All,

Finally getting around to closing the case & putting the top end on our 787 GTX. Got a new Wiseco 1.0mm piston kit with the deal but... no thrust washers P/N 290 832 420, or new P/N 420 832 420. Wondering if any of you have some spare top end parts for sale and would be willing to sell the thrust washers (4 total). Atlantic has the full set for $30 a pair, but the delay in delivery would shoot down our June 6th day out. We've got new needle bearings but will buy spares if you'd prefer to sell the parts complete (listed as #16 on page 8 & 9 of the pdf parts manual). Used is fine as we're talking about using the thrust washers not the bearings themselves.

Thanks for any help!

Do you have the OEM individual needle bearings or a caged needle bearing?

Thanks for the reply PWCdoc,

We've got the caged that were included with the Wiseco kit...

In one other search I found that Wiseco advertises: "... Complete piston kits include High-Performance forged pistons, rings, wrist pins, circlips and top-end gasket kit for one complete engine... Kit numbers WK1251, WK1252 and WK1253 order bearing number B1003. All other kits will use an OEM wrist pin bearing."

Because my Wiseco kit was from 1999 the part number was superseded but it did include needle bearings so I assume these are correct but... are the thrust washers needed? I took the caged Wiseco bearing to the dealer and they had the ...421 P/N in stock so we compared. Both the Wiseco caged and the non-caged OEM bearing (with end washers which I assume are thrust washers) were dimensionally the same.

In any case, thanks for the reply...!

You don't use thrust washers with the caged bearings.

Chester is correct and that's why I was asking. The thrust washer in the OEM setup is there to keep the needle rollers in place. The caged bearings have all the components incorporated into them so you don't need to worry about the thrust washers.

Hey

I have a problem with the gtx 2004 seadoo model. I have one at home and its supercharger has just went bad. We only had 63 hours on it. I want to repair it myself but I need to find the lowest prices for what I need to work with. It's doesnt seem like it would be that hard. The guys we went to and asked to repair it asked for $1200!!! Their INSANE! I know I will need the washers probably a manual and some special tools? I've been looking around and seadoo has already been preparing for folks like me by jackin' up the prices on these items. :ack:

Chester/PWCdoc thanks for the input. I had assumed that the thrust washer was only for the non-caged bearings but wanted to get a second opinion. Maybe I should send this to Wiseco so that they'll know the answer to this question next time. In any case thanks again for the info.
