Anybody have any idea why my hydraulic pump
would be making a grinding noise? Had the engine
rebuilt and the pump wasn?t making any noise. Put
I‎t back together and now my pump is making a
grinding noise. I?ve tried to upload a video but I‎t
won?t let me. If anyone is familiar with these pumps,
if you?ll email me at [email protected] I?ll send
you the video.
 
Not sure what you mean by "grinding" noise.

Did you set the drive gear backlash when you reinstalled the pump?

Can i send you a video i took Dean? I watched a youtube video of how to install and bleed the air out. I‎t didn?t mention anything about backlash.
 
Did you tighten the camshaft pump drive gear? I would remove pump and check for metal debris. If you have worn crank and camshaft gears they will make noise at the pump when you are lifting something.

I forgot to ask, who rebuilt the motor? Was the camshaft thrust plate checked? I have seen them broken before. If you pull the pump, pry a big screwdriver against the bolts and see if you can lift the rear camshaft driving gear any. I have an engine that either has a worn camshaft or camshaft bore or both. i could raise the gear 1/8" - 1/4". I quit driving it.
 
I took the pump off and the camshaft gear etc has
no slack what so ever and there was no metal
shavings or anything that looked abnormal. Can i
send you a video of it running?
