Hello all!

Well I got my Prince pump yesterday and started to make the fittings for it.  I went to two NAPA stores and the said they could not match it to my current hoses and did not have any fittings to make new hoses (they said the Prince pump had metric fitings – not so they didn't have a clue to the fitting size).  I live in SE Georgia in farm country and there isn't any real tractor shops for about 40 miles. Go figure! There is some small shops, but what I went through last night and today for cost and time I could have paid a shop from Atlanta to come out and set me up. I did not put a filter on the suction due to no one having fittings for the hose ( I purchased one from Surplus). My next attempt will be a filter on the return line like Bob did.

I had two different shops make me adapters for my factory hoses to fit the Prince Pump. One shop made an externsion for the high pressure side and another made the suction hose.  They made the suction hose the same size as the factory  5/8″ and I am thinking that is where my problem is.

I cleaned and pressurer washed the inside of the sump tank to make sure that all the rust was out of it, took out the PRV and cleaned it (there is a split white plastic spacer next to the “O” ring on the PRV, I take it that ring is split to be able to fit on the valve, if not do I need nother one?  Then hooked everything up and filled the tank with NAPA RO (10 weight) hydraulic fulid ( could not find anyone around here that had or heard of mulit vescosity AW32/46/68) I feel like I am living on Mars when it comes to parts and modifying/repairing this tractor in this area.

When I started the tractor up and engaged the PTO the BH jumped to life and the cylinders were working, but when I put the rpms up to 1,200-1,500 the pump started to “BUZZ” and the controls stopped working.

I am thinking that the return line is not big enough (5/8″) to produce the volume of suction needed and the pump is cavitating.

I most likey need to start all over and get at least a 1″ suction hose and make an adapter for the fitting in the reservoir  tank to remove the banjo fitting.

Any thoughts?

Thanks

I contacted Ronald and the head bolt torque is 140 ft lbs

Intake valve adjustment is 20mm

Exhaust valve adjustment is 25mm

Thanks

Thanks

I am getting ready to order the pump and make the return line filter system like you have. The Prince web site also recomends putting a filter on the suction line. Should I get the 9GPM 3/4″ or 25GPM 1 1/4″ .

Thanks

Bob:

That is a nice set up you made.  I'll have to go to the store and make one like it. Probably get the filter & housing at a auto store and the pipe & conections at a hardware store

The reservior tank came with the hoe. I just measured it and it is 7 gallon (looks smaller) and I take it that the PTO bolt on stock pump is 7 gallon.

The hydraulic oil I am using is ISO 46 (20W).

 I should have put a temp probe in the oil to know the exact temp.

What size bucket do you have on your LW-6 and what PTO pump are you using?

Thanks much!

Thanks I give them a call.
