crank bearing instal

[two-stroke-brit]

Well i have a 98 kdx 220r that i am rebuilding.
needed crank seals and bearings as well as a host of other issues( beat to near death ).
have it all apart and replaced the bearings in the cases and slid the crank in one side ,
went to put the other case on and NO GO.
checked things that could be hanging it up all looks good.
finally measured the bearing and its 0.01 mm small .
now i checked both bearings i removed and they are -.005 mm at most small.
i had the crank in the freezer and the cases in the texas noon day sun ( too hot for bare hands).
before i reorder another and hope for a bigger bore.

any ideas i am reluctant to directly heat the bearing as the rubber crank seal is right there.

Wow interesting, these were bearings supplied by Kawasaki Mark?

(loved the KDX's back in the day... had a mid 90s 250SR but the 220 was a much better bike really for off road, the 250 was a flyer with the Boysens drilled apparently as its a detuned KZ motor really, I never drilled mine and its was more than fast enough as it was lol)

It's gotta be the wrong bearing, doesn't it? Production tolerances are pretty consistent with bearings, right? Either way, I'd be going after another new bearing for that side.

Very strange :/

watched a video on a guy using a socket heated up with a torch then placing the socket in the inner race to transfer the heat and was able to install the bearing on and off for a good minute.
i will turn up a heat sink out of copper and try this.
