Low Oil Pressure On Fresh Rebuild

:D

Was the Relief Valve Seat removed for cleaning and was it re-fitted ?

It could be the relief valve cracking pressure is too low. Is the Relief Valve Spring new ? If so, Try adding a washer under the cap to put more pressure on the spring. Don't go crazy here, just put one in to start with and then if need be, add another, little bit by little bit.

Just a further thought, the spring wasn't shortened at some point in time for a ball bearing was it ?

 

 

Hi all,

 

Want to thank you all for your input.  I leveraged Spider's great insight - removed the PRV and hit the seat with some high air pressure.  Also removed the oil pressure connection and did the same.  

 

Turned over and immediately was at 60lbs at start, with my adjustable PRV out all the way, so there is room to adjust upward if needed.

 

Thanks again Spider and the full team.  

 

Now on to further fine tuning!  Thanks again!!!!

 

Best,

 

Shawn
