Stump grinder build

[skeets]

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.

Did you say a lot of naughty words???? Around here the air would have been BLUE !!!! .lol

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.

I have two lines of thought on this. One is to use quick disconnects so the pump can go on first with nothing in the way.

The second thought is having the pump sit in a 'cradle' on the front of the oil tank at about PTO shaft height. Back the tractor up close and then slide it from the cradle to the shaft.

Once I get the notch in the tank for the upper link clearance, I can raise and lower the frame/tank and try to visualize which idea would be the best.

I pretty much take these things in stride. Stuff like this happens in everyone of my builds. I guess I've learned to laugh at myself and I don't mind sharing a chuckle with y'all.

Quick disconnects sounds like a solid way to go. But then again, the cradle idea, with hoses a little extra long sounds like a good idea as well.

Couple of pictures with the unit raised. I'm going to install a notch for clearance of the upper link in the tank this weekend. Then when I can raise it all the way up, I'll start playing with the hose routing on the suction side. Going to be a challenge for sure because of the limited space to work with, but that's how I want it.

The other picture shows it raised about 7" off the floor.

Installed the notch in the oil tank for clearance on the upper link. When I tried it on the tractor, I didn't like the angle of the tank in the raised position. So this started a whole domino effect of changes that I'll be posting as the week goes on.

Dude, I wish I had your welding skills.

After staring at it for awhile, I realized that I needed to raise the upper link attachment point. It was going to have to be stronger than the original formed angles, so I decided a backing plate out of 1/2" plus welding on 3/8" plate for the pin holes would be a good place to start.

Now the tank lifts straight, but I still have an interference issue with the top link. Instead of carving on the tank again, I'm thinking of going with a dedicated top link that will arc to avoid the tank.

One of the themes for this build seems to be making fittings. I needed a 1-1/4 NPT street elbow that I could weld to my new torque arm for the quick connect to the pump inlet. Found a piece of 2" cold rolled square and proceeded to machine and then tig weld the male threads.

 

[Yooper]

I redesigned the torque arm so it would stick up higher and provide a spot to weld on the 1-1/4 street elbow that I made. Its at the point now where I'm waiting on the custom upper link so I can raise it all the way up and locate the fitting. This is where my giant quick coupler for the suction side will attach.

I figured someone was going to ask if I could still get the tranny filler cap out with the new bracket, so I took a picture that proves that I can.

 

[Yooper]

I might have gotten a little carried away by using 3/4" plate for the upper link, but I'd rather over build than under build. Machined the holes for a press fit on the ball ends and tig welded them in. Hooked it up for a test fit and raised it all the way up. Looks like we have a program!

What'd you cut that out with?

Where would us boys be without them?

Modified the torque arm to accommodate the large QC for the suction side. Installed the tank and tack welded it in the best position I could for the tight clearance. Welded the fitting on permanent and got the hose to the pump all set.

Modified the torque arm ....

Sent you a PM. Thanks

Yooper- Whereabouts in NE Wisconsin? I'm an old Wisconsin boy myself, back when I was a wee one. Depending on family health/responsibilities, I may be heading your way this fall, to wife's uncle's place in the UP, near Escanaba. Maybe I could pop in, and worship at the feet of the master.

I'm just north of that city with an NFL team, I forget what they're called. (Just kidding!)
Escanaba is where I grew up.

Hooked up the tank with the suction hose and brought the queen outside for some sea trials. I backed it up to a ditch and lower it all the way to check the hose length. I'm going to let it pass, but another two inches would have been better. I'm ordering a hose clamp to clamp it near the link to avoid chaffing.
