USADrifter Posted June 19, 2008 Posted June 19, 2008 The 2200 manual says that the oil pressure range is 31-76psi. Will anyone share the pressure they are seeing once warmed up, stable, and cruising? Anyone seeing much flux in the pressure (aside from throttle changes)? Thanks, Ken
Captain Posted June 19, 2008 Posted June 19, 2008 Ken There was a bit of a discussion of this subject here previously, but you'll need to convert from kPa to psi. See http://www.recreationalflying.com/forum/showthread.php?t=9369 Regards Geoff
jetboy Posted June 19, 2008 Posted June 19, 2008 Ken, some data from my installation, 2200 running Aeroshell 15W/50; after 25 hrs no oil cooler adaptor, ELO sensor in std. position, startup 50psi 2400 20psi 220degF 2600 20psi 230degF 2800 22psi 230degF 2900 22psi 240degF at 50 hrs with oil cooler adapter and hose fitted startup 50psi 2800 50psi 180degF 2800 47psi 200degF 2800 40psi 220degF 2800 35psi 230degF with oil cooler 2900 42psi 220degF at 200 hrs with new VDO sensor on lower port (oil gallery after cooler and filter) startup 50psi 2850 38psi 160degF 2850 30psi 190degF SB004-2 was carried out after the first tests and made no difference to pressure readings. The factory sensor failed and replacement was installed in what I consider the more important position for the last readings. gauge was VDO 0-80psi throughout. Ralph
glenns Posted June 19, 2008 Posted June 19, 2008 Ken, 9 out of 10 times if you are getting an unstable or low pressure it is the sender. Try replacing that as a first option. I cannot remember the exact reading but mine certainly sets nicely in the middle of the green and doesn't move. I have on a number of occasions had issues however and the sender was the issue (2nd engine)
Captain Posted June 20, 2008 Posted June 20, 2008 This issue of oil pressure sender failure has been mentioned a couple of times here in various threads. Mine is just how Jabiru fit it up, however it is interesting that in Dynon's instructions for their instruments they state that the sender should not be direct mounted to the engine, and should therefore be mounted remotely to get it away from engine vibrations. If mine plays up on the 3300 I'll be putting a flexible pressure line between the engine and the sender to try to solve this issue as identified here by others. Now .
USADrifter Posted June 20, 2008 Author Posted June 20, 2008 Thanks folks. I am seeing an average of 40-43psi during operations. Before I did much trouble shooting I was curious to see if I was even close to correct (as the max of 76psi is quite a bit higher than 40). Given the above responses I'm probably okay, yet the sender may be causing the flux. One step at a time ....
