Crankshaft to fix
Posted: Wed Jun 01, 2011 9:14 pm
I am building an new engine to my KR-1 and I bought KR-1S engine to replacing the original low km motor. I got bought one from ebay in decent condition. I necessarely needed to check it and rebuild with some new parts.
Now I have crankshaft in a shop and my mechanic called today to tell about the problem. The generator side big end crank pin had some corrosion marks from the pin bearing and he didn't suggest to use the old part. Maybe cooling fluits had flowed to the crankcase and stayed there for a while. He is now staying and waiting for my call for how we continue.
I have wondering how to solve this problem from a point of view that there is no spare parts to get here from Finland. There were only 5 KR-1 's imported at the time and there is no reason to believe that there are more than two existing anymore exept one odd KR-1S lately arised...
Workshop manual says that in the case of major damage there is no other way but change the whole crankshaft with the balancer as well. How strict is that? Is someone having experience with changing only that half of the flywheel (whith the pin)? How badly that would affect the balance cause I think that is only problem in whole case?
I would be greatly thankful if someone would have solution to my problem - having good usefull and matched KR-1S (maybe KR-1 fit as well I don't know really) crankchaft and balancer for sale some decent price or then real experience how to do it with changing only that flywheel half. Yess, in this case I am lacking that part as well!
Make offers in pm or sell this on Ebay.
There are every now and then some interesting parts sold on eBay but sellers would not ship in Finland and I wonder why cause I haven't face any problem in shipping or payment either.
Sooner I get my crankshaft properly fixed I assume that some of you would be interested to hear more about my "eternal" engine project that is im afraid coming to it's end...[-o<
