spring oil pressure relief valve P/N 21352


Philippe - doesnt that relief valve control the upper limit i.e.
opens at pressures greater than 35psi? - Mike

I agree but with a very weak spring, it work for me... Why not try
this first? ....


If you have a weak spring, your higher power settign OP will also be
low.

Yes, it was...



oops, sorry, he didn't say it was normal, but he didn't say it wasn't...

Bertie - my upper OP is within the limits of 10-35PSI.
It's my OP at idle that concerns me.
Specifications for the A-65 show an acceptable range of between 10-35
and I'm concerned I may be below that range at idle ( at operating
temp).- Mike

Do we all agree that a pressure relief spring probably will not figure
into the fix for the problem of raising my OP at idle? - Mike


Um, no, the range for the A-65 is 10 minimum for idle, but it's 30-40 for
higher settings. If you've got less than 30 when your oil is hot,
youhaven't got enough, unless you've got an a-65 I've never seen! My old A-
50 was the same, BTW What's the source of info for your figure of 10-35?
