Hi all, i thought to share this:
As mostly all these follower spindles are a bit on the piss, relative to the CAM spindles, due to the fact they have a thread to postion, at one side and a hole on the other.
The cams wear unevenly and a bit more valve clatter there. Never liked it, so the head starts to work.....
Finally after my 5th casings repair i saw that the hole into the casing is rather deep, say 3/4 or so (it will differ of course).
This will provide more thrust than a normal spindle hole
So i reamed (or hone'd ) it out clean, than made up an hardend axle, 0,02 mm interf. fit, and honed a follower acordingly (no interference fit) lenght 47 mm.
One side i made in a thread M5 and after assembly of the follower and axle, plugged it with a bronze thread part glued in place.
M5 12.9 bolt in,
ready!
cheers
