I have a used oil pump out of my ITR motor before i rebuilt it and put anotehr OEM in its place. Now i am building up a B18B and i want to be sure that this pump will be ok to use in my new motor(for a LS teggy), is there a way i can test it to see if it will perform well?

 

You can take it a part and measure the clearance in the gears and look for scoring on the walls if metal passed through it. The clearance specs are in the manual.

 

Cool thanks

Is there any place i can find the specific clearances on this, perhaps maybe its just in a helms manual?

 

Here's what the manual says.

innet to outer rotor clearnace New .04-.16mm(.002-.006in)
Service Limit .20 (.008)

Pump housing to outer rotor clearance New .10-.19 (.004-.007)
Service limit .20 (.008)

Pump housing to rotor acial clearance New .02-.07 (.001-.003)
Service Limit .15 (.006)

 

Thank you very much, i appreciate all the help
