[Healeys] Drove the Healey today?!

[gradea1 at charter.net]

UH OH! that is your slugglish issue! I would drain that oil (for rear
ends) and replace it with the 30W ND. That rear end oil foams in the
annullus and plays hell with the spring pressure, passage thru the
system and fast clutch engagement. Check it out on the web...that
heavy fish oil is not for British Trannys. If you put the heavy stuff
in to stop leaks, that's not the answer; neither is synthetic-too
thin.The gearbox and OD were designed to run on conventional
oil...ancient as it may seem. Yes, a small air compressor is enough of
a blast to clear passages.You will probably hear the clutch pistons
engage if air is put on the valve opening. If you remove the spring,
ball, and plunger with a magnet, you can then extract the valve and
run a small wire down the middle to clean it-then a blast of air-be
careful to not get any lint from a shop rag into the mix. Upon
rebuilding a unit it is "suggested" to carefully enlarge the valve
hole to 1mm (but cleanliness is probably best solution). The new
pistons sold today, and made by Overdrive Spares, (old Laycock group)
are equipped with rubber o-rings. Good that you replaced the tire
bushings! Hank

	Yes thanks for the tip. The problem is slow to engage. It was
suggested maybe accumulator O ring. Just did pull the check valve and
all. Did seem like dirty oil. I cleaned it all up. I’m already
committed to extracting the accumulator and piston but wanted to
replace all the tranny mounts and bushings which I did. Mounts were
pretty squished and cracked. Bushings(radiator saver)were fairly solid
but were replaced. They were the original. Cleaning and degreasing as
I go along.

	 If(?)it is the O ring or rings, I guess they are metal on the
piston, I might just spring for a uprated from Dennis Welch or AH
spares has a combo housing/piston both which have rubber O rings. 

	 Working my way to the extraction part. I want to use forced air
through the operating valve but I only have a small air compressor for
tires. Some kind of extraction tool would be helpful. (18G182) I have
always changed tranny oil regularly. Used ND 30 early on. Using MT 90
now for many years. 

	Any and all suggestions appreciated.

	Warren- Don't know the OD problem you are experiencing, but suggest
before you tear into it, undo and clean the check valve and ball on
the top right side (if you haven't already done so). One small spot of
dirt lodged in the valve drilling can kill the hydraulics and make it
seem like a bigger issue. It may be worn parts, but, if not, this is
an easy first test. If it is dirt; good idea to change oil and add
fresh SAE 30W non detergent oil to the unit. Regards, Hank,

	I should really get back to working on that accumulator OD problem
now?
