Stump grinder build

[Lil Foot]

Looking really good,, and I have to ask where did you find that itty bitty floor jacl

Looks pretty similar to my teeny one:

Started getting the pump fitted up to the tractor PTO. The angle brackets for the upper link on the 3PH were in the way, so I marked them and machined off the angle legs with a roughing end mill. I chose a 3/4" end mill to leave a good fillet for strength. Ordered some Kubota gray for touch up.

Now that the pump fits the PTO shaft, I started planning the torque arm. My plan is to use the center holes in the 3PH upper link angles and a long 3/4 bolt with either a spring or rubber cushion on the end. The pump will still be able to 'float' on the shaft with this arm plus it will keep the pump on the shaft.

Will these Prince pumps self prime? Designing the oil tank and planning the hose routing and need to know if the oil should gravity feed to the inlet.

Only managed to get the torque arm done for the pump this past week. I'm going to weld a nut on the left bracket so I can mount the pump and with just one bolt, it will secure the pump to the PTO. Going to use a spring or rubber cushion at the end of the bolt. Also a cotter pin at the threaded end so it won't loosen up.

Sorry can't answer your question about self priming.... am curious though.... how are you going to get to the IN port now that you covered it with that bracket or is the photo deceiving and the port sits well outward of the bracket?

I thought that, too, looks like a trick of perspective...

It was trick photography.

Yes it should be a self priming pump.

 

[Yooper]

Yes it should be a self priming pump.

OK, thanks! Got some fittings on order and if my first idea for hose routing works, gravity will do its thing. Good to know if I have to resort to plan B.

Some more progress on my build. Third picture is the final pump mount set up. The other pictures are of welding the oil tank which I designed to fit inside the 3PH. I put in a good size baffle in the center to split the intake and return to insure the oil gets homogenized to help control temperature. There is a port in the tank for a thermometer to monitor temp.
The second picture is welding the 10-32 tabs in place for the fill/vent, which was all for nothing as you will see coming up.
I always pressure test tanks with air and soapy water, and when it comes to plugging the holes, anything and everything that works is the rule.
Tank capacity is 27 gallons filled to the top. Prince recommends a 25 gallon reservoir for the pump that I have, so I'm good there.

Made up these mandrels for installing and removing the reusable hydraulic hose ends. I want to make up my own hoses so I can dial in the correct length, such as for the boom extender cylinder.

everytime I stop in this thread I feel I should

Yeah, me too! Plus, when yooper recently took a couple days off and didnt post, I thought I was gonna have the DT's

Keep em coming yoop....

 

[Yooper]

Easy now, guys! My head has to be able to fit through that shop door.

 

[Yooper]

I would have sworn the instructions for the fill neck said five holes, but no, it did say six when I went back and looked at it. So, I made up an adapter plate and welded this on over the opening. Probably better this way anyway, the sealing surface on the adapter is flatter than the tank top. Got away with this one!

The other pictures are getting the tank mounting plate fitted to the main frame. This bottom plate will support the weight and I'll have two angle tabs mounted up towards the top on the tank

 

[Yooper]

Some more pictures of mounting the oil tank.

Looks like that top link gets awfully close. Is that all the way up?

Good eye! Yes, it gets too close. Going to put a notch in the tank this weekend.

One question I have: Hard hard will it be to hook this all up when mounting on the 3PH? Reason I ask, looks like it would be rather hard to reach in there to line up the pump to the shaft and hook up the torsion bar.
