ginger0195 Posted June 26, 2008 Share Posted June 26, 2008 does anyone know what is the best way to split a crank case? (its a vertically split crankcase if it helps) Adam Link to comment Share on other sites More sharing options...
jimmythehat Posted June 26, 2008 Share Posted June 26, 2008 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 Link to comment Share on other sites More sharing options...

I think its the tight fitting bearings that are giving me the trouble. Should i use a wooden wedge or something similar? Adam Link to comment Share on other sites More sharing options...

Adam 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 If you click on the view full size and then click on the image that uploads, you will be able to read the instructions Link to comment Share on other sites More sharing options...
