1983 WR250 Engine

Hi all , have finally got round to having a look at my WR.

Have tried a search look for a rebuild thread but with no luck . So any tips or tricks.
Is the primary gear on the crank a press fit special puller.

Thanks in advance Dave

crank gear is press fit, rebuild procedure same as any other primary kick 2 stroke swede pretty much. there are those who use home made tools but yes a special tool is needed to remove gear. slippage can break the case.
i have one of the reproduced factory crank gear pullers and really like it.

The crank gear is what I would call a taper fit. My idea of a press fit would be a cylindrical fit with a small amount of interference fit and a key of some sort. You do not need a "special" puller but do need one that can get a hold of the gear without bumping into surrounding stuff, case mostly.

Pretty sure I did a little thread back in 2011 but search does not seem to go that far back but found the pictures. This had a messed up crank stub on the ignition side. Just what pullers and attachments I have created.

Thanks for the info guys.
