New Riva crankcase thrust surface repair kit

Agreed, looks like this one cant fall out. Worked on several Mitsubishi Eclipse/Eagle Talon turbo cars years ago and they liked to drop the insert thrust bearing out, but it was a much smaller half circle thrust washer setup instead of a plate setup like this. Lots of engines to be saved with this fix. Great job Riva..

I think its held by the crank once its put in.

Correct, it is held in place once the crank is set in the block. It's also held in place when the other half of the block is bolted up. Also, when the block is machined, it creates a "pocket" that captures the bushing. In other words, it's not going anywhere.

Very good work RIVA!

Ive had 2 fixed by having a bead laid on the scuff on the block and hand file fitting the bead to get crank end play to spec and works great, but this is better. More durable than aluminum for sure. How is the plate attached to the block Jerry? Cant tell from the pic.

So is there anything we can do in the first place to stop this from happening? Also does the kit come with only one face? I damaged more than one face on my block when my crank walked.

you could actually do this to both sides of the main bearing web and create a thrust washer forward and rearward

Nice fix. I have been using the thrust bearing from the Kawi Ultra to do the same job.

this is a huge problems for SHO conversions as there are no pads on the inner bottom of the hull to help keep the motor from moving forward under heavy load, the coupler really doesn't keep the motor from moving, great idea RIVA

Seadoos have a thrust bearing..

[toxicgun]

We need that for seadoo motors

Riva did mine when they did the work on my engine as a standard option.
Mine also doesn't quite look like that.

Jim did you see this?
