The A-Type non return valve operates as a check valve for the oil pump. If the valve is leaking or not closing etc. you will not be able to develop full operating pressure which should be in 450 to 5

Actually, the spec pressure is 350 for a large accumulator type (pre TR4A) and 450 for the later ones with a small accumulator. Racers prefer the large accumulator and often go to higher pressure for

It essentially functions as the exhaust valve for the hydraulic pump. On the pressure stroke, the ball lifts and allows oil into the accumulator; then when the pump piston returns, the ball seats an

It's a very good article; and yet I wish it had included a copy of Steve's warning. I found out the hard way. The pressure on the bench and in the car looked fine at lower rpm. But the spring was re

Steve and Randall, We didn't include that warning, because I had never heard of coil bind occurring in these units. I tested the springs with a valve spring gauge with a range that didn't allow me to

I'm sorry, Larry, I don't recall the thickness of washers. Maybe around 3/16". It was a large accumulator, and I had shimmed it from around 300 (no shims) to around 450 psi (original TR4 workshop ma

I normally shim them with plan hardware store washers that are about 1/16". These old springs always seem to be a little week, but I have never had to use more than two to get an OD back to spec. I c

I agree. But I believe that part of those discrepancies are that the OD operating pressure was customized for every car/engine (and of course for IRS). Some people seem to feel that it should be the

Randall, while all this tech talk is way over my head, I can attest to the fact that after 3 years and 18 races what ever size washer Larry used, it works just fine. Sent from my iPhone operating pre

I'm not arguing with that in the slightest, John. In fact, I'm not trying to suggest that Larry has done anything "wrong" at all. He knows what he's doing, and he's good at it. Just trying to transfe
