Timing Gears.
« on: 25 Nov 2019 at 19:46 »
Hi Friends I would just like to know where these timing gears came from! I have an identical pair taken from a MK engine,and  can  see that they are wasted in the centre and therefore very much lighter in weight than others I have seen. Many thanks.  Phil1ftp://.

Hi Phil,
            They are probably from a wartime Douglas Generator engine.

Hi Eddie thanks for your reply re pre war timing gears. My next thought is as they look in pretty good shape and considerably lighter, bit like pre unit (Triumph) I would like to use them in the MKV. Regards Phil.

Phil,
       I have heard of owners using them in Mark series engines, but I would suggest you compare them carefully with a set of genuine Mark camwheels - the timing marks may not be in the same position relative to the keyway! I know for a fact that the crankshaft gear looks the same as that on a Mark, but one has the keyway in line with a tooth and the other has the keyway between 2 teeth. There are, however, advantages to using these gears - being from a generator engine produced under a government contract, the materials used were to a higher spec than those used in the motorcycle engine.

   Regards,
                   Eddie.
