New to the T world. I have a 26 touring and I'm in the final stages of a motor rebuild. I have a question on the cam play that I can't seem to find anywhere. I used my old cam bearings and now that it's in the cam moves from the gears being in perfect line to the cam gear touching the front cover. It does have some resistance when I pry it back and forth. Where did I go wrong? Thanks in advance.
Sounds like you have 26/7 front bearing on a earlier cam shaft, the end play is set with the front bearing, early shafts have all the same width in lobes but the late one has the #1 lobe about 1/8" wider, a combination of late bearing and earlier shaft will give you that 1/8" of shaft moving forward to touch the cover. hope you make sense of all that!
Makes complete sense. I'll check that when I get home. I thought I might have had the 2 cam bearings switched but if I reverse them it defenatly rubs on the cam lobe. Is that normal or dead wrong?
Need some more info on what you are putting in, as in what cam,early or late, if ground or stock, a early ground cam requires a thrust kit to stop end play, photo's would help.
What the spec would be is to get about .004" end play on that front bearing.
The diff in the 2 front bearing set-ups.
If you have a correct front bearing with .004"ish thrust clearance than look at the hole in the bearing for the bearing retainer bolt. This should be a snug fit,I have seen a lot of play in that area. You can build up the shoulder of the retainer bolt or replace the bearing or sometimes both to fix the problem
Sometimes you can solve the axial play problem easiest with a set of thrust shims between the timing gear nut and the timing cover. Chaffins sells such a set, but it's easy to make yourself. I made it with a couple of standard steel thrust washers from a machine shop and a delrin plastic washer in between custom fitted to the needed thickness.
Well I had the early camshaft. And I had the bearings switched around. All is good now. Just hope it fires up and runs ok after I drop it in tonight!
Let us know Aaron!
