Crankshaft bearing question

[Goldfox_32]

What is the name of the bearing at the bottom of the cranks shaft rod where the piston rod attaches to the crankshaft and can u replace it without buying a whole new crankshaft?

Crank bearings??

You can get them rebuilt from KOR. Or buy one, whatever you want.

It's not a crank bearing it's the bottom of the piston rod bearing

I'm trying to buy one but can't find one all it pulls up is the crank bearings

 

[Herpderplol]

If you say you couldnt pull apart the carnk, why are you trying to buy them?

I suggest sending your crank to KOR if you want it rebuilt...

That's the crank bearing, the ones on the end of the shaft are main bearings.

I never said I couldnt pull my crank apart I asked if u could

Wrist pin bearing(small) is at the top the rod, rod bearing (large) is on the bottom of rod, crank bearings (2) are on both sides of the crank haves.

Alright thankyou I just wasn't sure if that was it

Unless you have good knowledge and a heavy duty press the crank bearing replacement is best done by a shop with the correct knowhow.

This is the part number and price from Yamaha:

BEARING, CYL.(3XP)
93310-523D2-00 (replaces 93310-522L4-00) $41.86

If the bearing is bad, the rod, washers, and crank pin have all seen better days and should be replaced. If you're going to split the cases, it only makes sense to do it right the first time. This requires new main bearings, rebuilt crankshaft, new seals and gaskets, new clips and lock washers.
