does anyone know what is the best way to split a crank case? (its a vertically split crankcase if it helps)

what bike is it my friend? are you completely completely sure you have removed all bolts etc, if so a rubber mallet on a solid thick area of the cases will help shock the cases apart

first of all thanks for the reply, i hav already split the case, but i can't get them seperate and i dont want to use too much force and damage the alloy cases. I think its the tight fitting bearings that are giving me the trouble. Should i use a wooden wedge or something similar?

Hi Ginger

You must not in any way lever or use a wedge between the cases the surfaces are flat and oil tight and wont like this treatment.

On old DT's in the right side crank case you will see two threaded holes, one is unused and opposite that there is a screw holding the crankcase oil seal retainer. You remove the oil seal retainer and you now have two threaded holes. You will have to make or get someone to make a puller that screws into these holes and presses down on the end of the crankshaft, take a look at this
