Cruise Control Vacuum Pump Posted by MC [Email] (#1472) [Profile/Gallery] (more from MC) on Mon, 14 Jul 2014 14:02:27 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Here's one for the C900 gurus.
'93 900T
How much vacuum should I be expecting the cruise control servo/vacuum-pump to make?
Pretty convinced this one is faulty; only pumping out about 7PSI MAX, barely enough to put a little tension on the accelerator cable at closed throttle. Definitely NOT holding it open.
So the question is; whats a GOOD spec for vacuum pump?
Obviously they are not available NEW anymore, so want to bench-test any used ones we come across to make sure they are going to perform well for the road test.
Any other good tips for reliable cruise control operation? or do you just kiss CC goodbye when you cant get good parts anymore?
