While we are on the subject, it has been debated through oil discussions about synthetic oil not protecting against corrosion during the winter months as cheap ole dino oil. At any rate, corrosion in bearings causes more than usual vibration, couple that with high rpm and you increase the chances of cage failure. My personal theory is the rivets let go first. The picture below is of 2 x 6305 SKF bearings. Notice those rivets look beefier on one compared to the other. I wish I still had the bearing but I had one from NTN and also INA that had even more impressive looking rivets. Maybe if you are out to a bearing house to pickup your bearings, ask them if they have different brands that you can compare. On my last rebuild, I actually opted to go with bearings with polyamide cages as they are recommended over steel for vibration. Unfortunately they don't offer polyamide cages for the bearing with the snap-ring though. I only mention this because cranks are expensive to rebuild and you can only rebuild a crank so many times. Best to shoot for your best bet on longevity.  I'm never putting another steel caged bearing on a Triple crank. As you probably already know I have polyamide cage in the snap-ring grooved bearing too, using this trick: Bearing modification.PK |

Can someone confirm these bearing numbers for the crank? 6305 C3 (x5) 6305 NR (x1) I am not having much luck for the rubber seals.....I have the left and right outer but not the inside ones. TC326210 TCY256210 Thank you Make sure the 6305NR bearing is C3 clearance also (6305NR/C3). PK |

When I stripped the engine I found the shift drum corroded and the shift fork on the drum was burnt.
I just bought a beautiful complete transmission on EBay. It arrived yesterday and looks brand new. Little to no wear on the forks and the drum looks like a piece of art.....lol
Got all the muck out of the cases last week and will start cleaning up the surfaces now.

No better feeling then getting a pristine tranny! I scored one on eBay a few years back for cheap.

Trying to put new bearings on my transmission.
All the bearings seem to slide right off/on the shaft except the bearing in behind the drive sprocket. Does that one need to be pressed off/on? 6205 NX3 is the bearing number
Thanks

"Normally" bearings with a fixed od and rotating id would have a loose fitting housing and a tight fit with the shaft. Give the bearing a crack with a soft drift on the inner race, it should move.
