R/RS Big end bearings
« on: March 02, 2018, 08:23:58 AM »
Does anyone  have an original big end bearing for an r/rs (Yamaha part # 93310-524D0) that might have the bearing manufactures code stamped on to it.  I'd like to search that bearing through my local bearing supply shop and compare prices.

Dont hang me on this one, and Im sure someone will chim in and correct me if Im wrong.

Big end bearing specs for 3XV are 31/24/16
The 16 (width) is the pain in the but I suppose.
While searching for big end bearings for my 3MA 31/24/17 - I also kept an eye to see if something for the 3XV would come up - but unfortunetly it didnt.

For 3MA 17mm Width - pretty much available - CR250 stuff

Are these still available from Yamaha. I'm sure I had a crank rebuilt with a complete rod and big end kit supplied by Webbs of Lincoln (Andy YPVS250 on here)
Mellion say If it ain't broke thrash it until it breaks

Thanks for the feedback guys, good to get the bearing size and code.  I'll run it past my local bearing supply shop and see what the result is.
They have been supplying me with mostly cycle part bearings to date and are coming in at less than half the cost of Yamaha 'boxed' items.  All these bearings are IKO or KOYO etc... so no cheap stuff!
I appreciate that there may be some items that are only available through Yamaha and I have no problem paying the asking price, but where I can source like for like and save in the process then count me in.
I'll let you know the outcome.
Cheers

looks like the 17 wide bearing is easily available, the 16 wide not so.  i'll check with local Yamaha dealer and compare to 123 Bearing.
