busaf4 Posted May 30, 2009 Share Posted May 30, 2009 I have a late 9b that just has the oil pressure relief valve. I took off the plug and found a spring. I could not find anything to adjust My 9 manuals do not show what the pressure relief looks like. Does anyone have a drawing. picture or know what pieces are involved to adjust the oil pressure I tried the squirt collection instructions (remove the line and collect a set volume of oil) as listed in the manual. I did collect the oil.I can not get the oil gauge to show anything, however. According to the manual, the gauge should read when there is 1 lb of pressureThanksArt Lee Link to comment Share on other sites More sharing options...
Steve Braverman Posted May 31, 2009 Share Posted May 31, 2009 Art,I hope these help. If you need more detail, use the part numbers to order the original drawings from Jeff Hasslen. If you want to see anything else, I have the entire Series 9 and 10 parts catalog. I can scan other pages for you. Link to comment Share on other sites More sharing options...
busaf4 Posted June 1, 2009 Author Share Posted June 1, 2009 Thank You Steve. From the picture it appears this is just a pressure relief valve to limit oil pump pressure. There does not seem to be any adjustment other than changing the spring. Let me know if this is not correct. The later 9B I know doe not have the needle vale to adjust oil pressure.I am probably going to bring either this car of the series 145 to the TrekArt Link to comment Share on other sites More sharing options...
