Have you put a gauge on it to see what psi you are getting? Are you sure motor is spinning at 3600
Yeah, and I checked the motor with a tach, it sits around 3450. Im wondering if thereās some kind of gearing thatās slowing the shaft down within the motor. I donāt have the time to take it apart; may just pull the trigger and get a Honda.
Yes, verified with a tach
I didnāt check PSI, I know its low though, id guess around 1000-1500
You need a 3.25 pully on the motor
Werenāt you just saying they were backwards? 3.25 would give me a 1.8-1 ratio; which would run the pump at 2000rpms and kill itā¦
I didnāt say they were on backwards I asked to make sure.

Sorry about that, misread it.
I would at least try a 3. Iām assuming you did the test without the ball valve.
Correct, no valve. Based on the output, it seems like itād need a 6" to get it to where it needs to be. Iām at a complete loss. I could throw a 3" on there, but 1/4" bigger is only going to spin it about 100 rpm faster. Agree?
Thats a 2.47-1 ratio. That would slow it down even more.
Put the 3 on it if you have one. I still think you need a 3.25 but thatās just me
To OP
Sorry, I didnāt read the entire thread.
But is the pump a direct drive pump? And you just put a pulley on it?
If so, Thatās your problemā¦ The inner crank in the pump isnāt geared to be pulleyed. Belt drive pumps have a different inner crank
I dont think from his pictures itās a DD pump
Unloader set properly?
Its a belt driven pump. The motor was from a direct drive machine.
Yes, I dialed it in.
Do you have a sight glass on that pump
Yes, plenty of fresh oil
