I run a simple Vicker's pump for my gurdies. I just replaced my old groaning Vicker's pump with a reconditioned pump. The old pump worked fine except it had a loud groan to it. Found that the cork gasket for the reservoir cap fell inside and got sucked into the intake hole of the pump. The replacement pump was gone through from my local pump guy and checked out good. After I installed the replacement pump it didn't pump. The clutch does work just no pump output. Cracked the output line to see if there was any seepage and there was so something is pushing fluid. Is there some sort of priming I need to do (even though there was seepage) or maybe I have a counter rotating pump? Anyone know how to determine if the pump is standard or counter rotating?
Thanks.

I have had more problems with my hydrolics this past two years than I care to think about. I also got rid of my old cickers pump and bought a new one. I have had them lose power several times like you described when the keyway in the clutch falls out, which has happened a nightmarish number of times for me until I got everything calibrated just right. It is also possible thar your pump is set up to turn lesft instead of right, or vice versa. I haver been as frustrated with anything as I have with malfunctioning hydrolics. I hope you get it figured out.

If it is a vickers vane pump it will have an direction arrow of sorts cast into the center section of the pump.The arrow isnt exactly like an arrow,but when you see it you'll understand.The arrow must point in the direction of shaft rotation or it won't work.Vickers vane pumps can be assembled for either direction,so if it is backwards you can switch it easily to the other direction.Good luck.

I have experienced the situation you describe with the vickers pump being in backwards. I have also had the bolt holding the key in the clutch fall out. Put some locktite on that bolt.
Wyolance has it correct.

Yeah, my problems largely cleared up after I added locktite. Keep in mind to use a lower strength formula, since you want to be able to take that bolt off again yourself. And you should also keep checking to see that the pump is bolted firmly in place, as it can rattle loose from engine vibrations and wear out your clutch (good thing I had a spare).

An old guy taught me the trick of using 5200 or sikaflex instead of locktite for any bolts or nuts, including prop nuts. the stuff pretty much guarantees things won't loosen do to vibration. Apply heat if you have trouble taking things apart. Put it on the exposed threads on the backside of a nut too.
