M40 Cam Timing - Special Tools. Firstly, I'm a newbie and so this is my first post... Now, the problem... I'm replacing the head gasket on a friends M40, cam belt etc and note that the manual refers to a locking pin for the crank, and a cam locking 'saddle' that sits over the square flats on the end of the camshaft. My question is, are there any drawing of these tools as they look simple enough to make (I have access to a lathe etc..) and, can the cam be timed accurately enough without the aid of the cam locking tool. There doesn't appear to be any obvious witness marks or pointers for the cam, however there is a definite arrow for the crank pulley. Any help would be appreciated.. Cheers, Tom |
