Bit of a dredge, I know...

Is there a bodger's method to remove sealed bearings on something like the novatec d771sb?

Basically it's got replaceable end caps, then a 6902 bearing on each side of a hollow centre that appears to be the same diameter as the inner bit of the bearing, so no obvious way to get purchase on it from the opposite side...

Also, no central axle to use to tap the bearing out from the opposite side, so do I need to actually buy an internal bearing puller?

There is a tube between the 2 bearings that has to be pried gently aside

Cheers! Presumably if I did buy/borrow a bearing puller, that central thing would just stay sat there in the middle. Any idea how it is held in, I can't tell from the schematic?
