From what I've heard its a no no to leave the seals on main bearings but we just had an argument over it (he saw the seals I took off). Who's right me or him? they are Nachi Japanese bearings and it would be a shame if they were ruined because of how he wanted them but I also don't like to argue with people at all. Should I leave the seals on the clutch shaft bearings but remove the seals on the main bearings? either way if they go bad after 500 miles I could say I told you so. I was rebuilding the engine as a Xmas present. If the seals were left on the main bearings wouldn't the grease be washed out by the gas and at the same time prevent them from proper lubrication? the guy acted like he was offended when he saw the seals I took off but I cannot understand the guy. He's disabled and forgets stuff and he was mad at me because he believed I ordered him the wrong motor before (the one that's on my bike now) for several months he was mad at me. Should I put the seals back on or should I argue? ugh. I don't understand his logic he keeps saying to leave the seals on so the grease stays inside but I told him that's for dry environments, he wouldn't listen. Do any of you guys that rebuild motors/have a shop encounter people that like to argue?
