Have just had cam and followers reground. The latter to 'R' radius.
The inlet cam part number is 71-2887 which does not relate to the T140 parts book number, it also has the number 20416 stamped on it.
The exhaust has been built up and ground in the past and again this time. It is difficult to read the part number but I can sight a 7--maybe a 0 a 6, 4 and a 2, it also has the number 20360 stamped on it.
Have cam lube ready for assembly, been told to wash and very lightly oil the bores and remember that the main bedding in for the rings will be on the first 18 revolutions of the crankshaft when started and then subsequently keep at high revs to bed in the followers and cams.
Both cam have the same profiles
