Hi guys,
I am home today for Presidents Day and... well I have some great
news. After a day and half of hard work... my rebuilt A-Type OD
is attached to my recently rebuilt TR4 gearbox. Boy... that was
hard work. I had to disassemble the gearbox and swap in the
shorter mainshaft and attach the adapter plate. I don't even
want to admit to how many mistakes I made along the way. I have
put a lot of investigation time, labor and money into this
project and I was very nervous about the outcome.
I couldn't wait to test out the unit. I filled the unit with
Valvoline 50W racing oil and attached my 1/2" drill to the pilot
shaft and fired it up. The drill is rated at 600 RPM which is, I
guess, barely enough to charge the accumulator. The drag on the
shaft in 4th gear seems a little heavier than without the OD.
The drill was laboring a little and was only turning something
less than 600 RPM. I had to let it run for about 40 secs before
it would kick in. I could tell because the flange went faster
and the drill speed and noise changed because of the different
load on the drill. It stays engaged for long periods and
disengages immediately. I hope this bodes well for the pump and
accumulator under normal operations
All this test checks is the operating function. It does not give
me a measure of the pressure at normal shaft speeds. I would
need a 1/2 drill or other gizmo that ran at 1500-2000 RPM. I'm
not sure the tool exists and whether I want to buy it just for
this.
Just wanted to share my good news. This is almost as good as
starting up a new engine.
