Got this 33 running but the only pressure gauge I have on hand is one of those that reads 0-100 and the needle doesn't move much at all. So I'm guessing it has a low oil pressure oil system. Am I right on this??
Thanks

I have a pony, 22, 33 and a 44, all gas and none of them run over 20lbs pressure. Dosent seem to matter if they have new brgs or not. I did shim the pressure regular up on the 30 and it runs 25lbs with 30wt oil!

I owned a 33 from 1969-1985. Oil pressure with 10,20,or 30 wt oil was always 15-20 pounds on 0-40# factory gauge. One of the toughest tractors I have owned.

I think most info on the 33 forgets to put range.
The models smaller and larger call for 10-20 PSI
I grew up with them at the dealership and in general 12-16 PSI was figured to be in range.
