A friend needs help to diagnose a problem with his TR4A Here is his
message.
Ronnie,
The problem noise I'm having with my TR-4A is what I would
describe as an amplified or extremely loud valve tap. The only time I
have this problem is when the clutch is depressed, and it seems to be
worse the hotter the engine gets. It's not noticeable when I first
start her up before the engine gets warm or after running at highway
speeds for a little while. But, once she's hot and running around town
from light to light the noise gets louder and louder. If I go through a
drive through, it gets really bad. I don't really understand the engine
temp factor, but the noise is definitely related to engine speed. My
guess is that it's probably the fulcrum pin between the clutch fork and
the shaft, which I replaced last time. When I last had the gearbox out,
I rotated the pins on the clutch fork which engage the sleeve for the
release bearing 180 degrees so that there was no wear on the part of the
pins which contact the release bearing sleeve. I'm now wondering if I
should have only rotated those pins 90 degrees, and that my noise is a
vibration caused by the gap on the back side of those clutch fork pins.
Or maybe I should just replace everything. What do you think?
Thanks Cameron
