John thanks for the info. I got some more done on the timing gears. Built a cam box and side plate. |
| John Stevenson:
Looking the biz. Do the cams go behind the gears ? |
| OKTomT:
Yes John the cams go behind the gears it will keep the box narrower. The main shaft boss puts the drive gear out to far. John I found this picture below on the net. I think its Norton. The lifters are not placed over the center of the cam shaft is this a good design ? |
| DavidA:
I wonder if those lifters (cam followers) are original. Having the sharp edge of them contact with the cam doesn't look very professional. I would expect severe wear of the cam. Dave. :scratch: |
| John Stevenson:
Tom. That picture doesn't look right, all the followers I have seen have been top hatted at the bottom. They are usual off set along the line of the crank where they sit on the cam so the cam first touches on one side and wipes the follower round. This is to equalise wear. I'll see if I can find a picture. EDIT Could be right, found this image http://www.nsamotorcycles.co.uk/ekmps/shops/nsamotorcycles/images/norton-16h-tappet-rod-guide-assembley-complete-1125-p.jpg |
