Oil Pressure Adjustment Unstyled B

Marmaz · Jun 9, 2022

Anyone know how to adjust oil pressure on 35 John Deere B. The manual says to remove oil adjusting screw nut cap on from front side of governor, and loosen lock nut on adjusting screw. Problem is theres no picture and Im not sure what to look for.

As much as I know, that will only limit the high pressure. If pressure is too low, it
won't change anything.

No help with the procedure, but a question. If it was turned down at some point in it's life due to high pressure, wouldn't turning it back up help with low pressure?

Perhaps. But usually low oil pressure in these is caused by worn bearings or light or diluted oil.

It appears all I had to do was ask. Right after I posted, I found the adjustment screw. Its a long 5/8 hex cap and lock nut on the front of the governor. Remove the cap, unlock the nut, and turn the screw. Youre even able to do it with the engine running. I wonder why they went away from that to the adjustment in the crankcase. Thanks for the replies.
