T500 Crankshaft O-Rings

[desmocat]

I'm in process of assembling a more street oriented replacement engine for the Repli-Racer instead of the full race version currently installed. Been able to build up this engine with parts mostly I have on hand, guess at times it's good to be a collector (hoarder?).

So I go to install the crankshaft from one that I had rebuilt several years ago, it was still in the unopened package from being rebuilt it in 2009. Once set in place, I had this moment of realization that the crankshaft O-Rings were missing from the bearing carriers. Guess this wasn't the best rebuild job?

Now I need to order O-Rings and find someone else to split the crank so the inner O-Rings can be installed.

Any suggestions as to who is doing crankshaft rebuilding at this time?

This might get the troops wound up, but what about giving the bearings a thin coat of case sealant? On clean surfaces of course.

I have been told you can fit those O-rings by VERY carefully stretching them over the crank. I have not seen this actually done I will add. You could always experiment with an old O-ring and see how you get on.

I've also heard that you can cut new o-rings with a razor blade, wrap around the bearings then glue the ends back together with Superglue

Could work I suppose - insert shrugging smiley here -

We do exactly that in the industrial world on occasion.

On my old GT500 I managed to stretch it over the rod, it's a bit of a heart stopper but it can be done.

Make sure you do it as swiftly as possible to ensure the o-ring isn't permanently stretched.

If what's been previously mentioned fails to work, Bill bune in Minnesota rebuilds cranks. He did mine a few months ago.

Hey Desmocat

Temecula Motorsports has the crank o-rings for $1.63. Buy a half dozen and see if you can successfully stretch them over the rods. Part number 09280-76001

Failing that:

or

Wisconsin Recreational Crankshaft

So I guess taking the crank back to the initial rebuilder is not an option?

You going to make it to mid-O this year?

I ordered the O-Rings and proved today they can be installed even with the crank fully assembled. It was a literal stretch over the con rods, but mission accomplished.

Thanks for all the inputs.

Jim I will be at Mid-O this year, at this point not racing the T500 but maybe the T20. Need to rip the Hustler apart to determine why it won't stay in sixth gear.
