Trouble getting right flywheel pullers

2 posts in this topic

Ordered flywheel pullers for my 03 wr450, from Fowlers Uk, came back and are too big, yet the part number in the manual and the part no on the pullers which states 04142, I have measured the pullers and it is inteernal thread of 33mm, on my wr, I measured the thread and it is 30mm, have things changed on the newer models :banghead::banghead:

Yes. The 05 WR has the 33mm threads, while the 03/04 have 30mm. This change occurred along with an upgrade to the left side of the crank journals and required a new rotor and starter gear (one direction #3). The crank end is bigger and eliminates the step down.
