Best place to have my crank rebuilt

[lick]

Hi,

 

Well the shee began to run a little slower then normal. It still ripped but just didn't feel all there. Anyways pulled the top end off and the left cylinder kicked out the cir-clip and the wrist pen tore into the wall. Went kinda deep. The cylinder didn't clean out till 1mm over. So back to the question at hand. The crank looks OK and seems to be fine, but I'd like to have it rebuilt for a peace of mind. What is a decent place that's not to expensive to send it out to. Any info on this would be great. Thanks

Crank works is a good place but if it was running with out any probs before you can just replace the outside bearings and have it welded and be fine,I think you can pick up a stk stroke crank new for not much more than the price of a rebuild.Im going to tell you my philosify on rod bearings and wrist pin bearings and this comes from experciance if the ones you have are working without problems and are not over worn then leave them alone.Ive replaced these bearings with new ones a few times on many types of two strokes and had them go within a week and the old ones ran for years.Especilly wrist pin bearings I think some are good and some arent no matter the brand and if you get a good set hold on to them untill they show wear signs and then replace them.

I dont agree, I think the above poster had a bad run of bearings. There is no reason not replace bearings just because they were workin earlier.

 

My advice, any shop that can do boring has a mchine shop, and can probably check the tolerances of your crank. Take it to them and ask to have it done, I dont know what they will charge you, but its gotta be cheaper than the worst case scenario.

I agree have the crank checked and if its on the upper tolerance limits rebuild it.I was saying I would not rebuild it just for the hell of it.As for the wrist pins Ive had the best luck with the oem yamaha bearings but I dont replace them with every topend rebuild from my experince its a risk with the old as well as the new.

Weigh the cost of a new crank vs. having yours rebuilt.

 

If it's only gonna be a 200 more or so to get a new one, that's a better investment.

Get some TZ or maxload bearings installed while you're at it.

I do agree with all of you. The only thing I was worried about was the bearings being kinda messed up due to the metal shavings and such. Then again if it checks out OK, I'll stuff it back in. Thanks
