Dear All,,
I would like your help in finding the correct Bearings for my engine, I had to take my crank to the machine shop and they said they must grind the crank which means I need to put in bigger Size Bearings. I was using NISMO Bearing and it was STD0 RRR40 but the workshop here don’t work with these numbers, so I need your help in :
1. Is it advisable to use the crank after all?
2. How will I know the correct size to use?
The work shop had measured the crank in came up with these figures :
Main Bearing size in STD is 54.98 and they have to grind the crank up to 54.48
Con Rod bearing size in STD is 47.98 and they have to grind the crank up to 47.73
Please help in finding the correct NISMO Bearings
Best Regards
Adel
