Hi everyone 

im rebuilding my 1979 DT’s engine that someone else took apart (it came in a box of bits) looking at the manual it says there are some shims on the crank between the crank shaft and main bearing. Does anyone know what size these are (diameter,thickness etc...)

kind regards

The shims were in place to take up manufacturing tolerance and therefore can alter per engine. best thing to go is :- dry run building the engine and see how much end float you get. However from memory those shims were about 0.01mm thickness each and most engines had 2 or 3 each side, so perhaps a single shim of 0,03mm either side will do .. but this will depend on end float

Most DT"s  have one shim, on right side,  [ primary gear side],  But,   i have build 3  engines,   and none had a shim on the crank,  they say its when tightening the primary gear - it pulls the crank to this side , and the shim gives clearance.   , ,all my engines had never been apart,  =  & no shim,
