Just had my engine rebored and will be fitting new pistons, rings, big end bearings, oil pump, water pump all the usual stuff. My question is should i replace the thrust washers on the crank as well i thought they would have been in the big end bearing set that i bought but are not. I have measured them and they are in the tolerance specified in the manual just dont if i should get new or use the old ones?

 

no, reuse them.

 

reuse em , just to stop crank floating!

 

Thank you very much just put the bottom end back together with new shell bearings, pistons and rings just need to spend some more money now on an oil and water punp
