Dear Sergeant J.E.P.,
Just because the gaGe goes to
60
pounds does Not mean that a readiRg of
60
pounds is "too high±. Fact is, your support's TM
9-2815±210±34
for multifUl
engines says, "An oil pressure of
75
PSI at
2,600
²PM engine sp³ed ´is
acceptabLe.± And it even points out, "THis is above the range of tHe panel
indicator.±
It's also a fact that normal oil pressure can vary quite a bit from one muµtifUel¶
engine to another·
So how do you keep tabs on oil pressure in a multifuel engine that happens to
have a normal pressure above the
60
pounds on your gage?
You just switch to a gage and a sending unit that ha¸dle HigHer oil pressure,
like it says in TB
43²0001±39±4
(an
8³).
²eplace t¹e
60²lb
gage and sending
unit with a
120´lb
gage and se¸di¸g unit:

stays above
80
