Swing arm bearings

dtrdave · DTR Senior Member

As far as i can tell from searching google, it seems it's :
Inside Diameter:       22mm
Outside Diameter:     28mm
Width:      20mm

This is assuming it's a 97-03 bike it would be part number 933152225100. The non yamaha part number for this is :NTN HK2220C.
So using the hk2220 of that part number on Simply bearings website gives me the above dimensions...

HTH

(Is it sad that i actually enjoy trying to find stuff like that on the net ? aww

)

well the numbers on the swing arm bearings correspond with the ones you put up :D
What about the bearing/bush that the rear shocker connects to (where the dogbones attach)? Are they all the same size before i go and order some?

You'll be ordering from yamaha anyway though no doubt ? ? So i'm sure they'll give you the right ones biggrin

Sorted done them all :)
anybody know what size the bolts are? the powder coating has got inside the star if the threads so i can't screw them in. Need to clean the threads with a tap but don't know the size.
