bobt Posted January 28, 2007 Share Posted January 28, 2007 Hi, Is there a position (No of turns for example) that I should have the adjuster in before cranking up the engine for the first time? or is it a case of suck it and see? Thanks Rob Link to comment Share on other sites More sharing options...
Mick Day Posted January 28, 2007 Share Posted January 28, 2007 Instructions I followed were as follows: "Make sure you tighten the locking nut on the pressure adjusting screw ( you need to guess the initial setting and adjust for the correct pressure once up and running), else you can get some leakage where the screw emerges." So I think I screwed it in about 2 turns. Start the engine & check OP through the warm up stage. Once the oil is above 50 c drive the car & check OP through the rev range. I set mine so that I had a minimum of 60psi at 4000rpm & above. Most of us with Pace pumps notice that OP at hot idle can drop; mine is about 13psi. I don't think this is anything to worry about as it's the pressure under load, & of course higher revs, that matters. Link to comment Share on other sites More sharing options...
Johnty Lyons Posted January 28, 2007 Share Posted January 28, 2007 Check the Pressure setting at cranking speed..... Pace have a habit of leaving the adjustment TOO high, result when she fires it fills the clock. If your getting 1 to 2 bar at cranking she'll jump to 6 bar when she fires. Just be very very carefull Pace 3 stage Dry Sump pumps deliver pressure way in excess of the requirement on a Se7en, even when using the thinnest synth. jj N.I. L7C AR. Membership No.3927.

bobt Posted January 28, 2007 Author Share Posted January 28, 2007 So does screwing the adjuster in decrease or increase the pressure? Mick, you say 2 turns in. I assume that is from a fully screwed out position? Rob Link to comment Share on other sites More sharing options...
Mick Day Posted January 28, 2007 Share Posted January 28, 2007 When I installed my pump the adjuster was only finger tight so a couple of turns seemed right. In view of what Johnty has said it would be worth checking where the adjuster is at the moment & maybe unscrewing it to finger tight & going from there. Screwing the adjuster in increases pressure: in effect it's an adjustable pressure release valve. Link to comment Share on other sites More sharing options...
