My JD 310A

[mhrischuk]

Just showing off my garden tractor. Since moving into our place back in 2000 I have always had the use for a backhoe, especially knowing I would be adding on to the house and building outbuildings. She has saved me a small fortune along with making me the neighborhood hero at times.

Here she is taking a mudbath..

I bought her back in 2006 or so. The previous owner cut a hole in the underside of the boom to replace the hyd lines. I kept saying I was going to weld some support structure around the hole.
Well I procrastinated and the boom did not.

These two pics are of the temporary repair just to be able to drive the machine around without the boom breaking off LOL

I got an estimate from a local welding/fab shop... around $2500-$3000 to repair it.
So i got online and found a used boom $900 shipped.

Borrowed a backhoe from the same guy I bought this one from to help with the heavy lifting...

Then the fuel tank sprung a leak. Tore that apart and repaired it...

Epoxy repair. The seam was rotted.

Fiberglass

Additional rustproofing.

Might as well flush the radiator...

Then the injection pump went. It began stalling. Would only run for short periods. I did some online research and found someone very knowledgeable who convinced me I could do it myself.

First was the diagnosis. Remove the inspection cover and look for what was described as "mouse turds". If they are there, the governor assy is most likely the culprit.

And so starts the rebuild...

Mark original timing location..

Disconnect and remove.

A good bath.

Disassembly

Broken bolts needed special attention..

internal pump

Damaged governor assembly. The black rubber was one big ring that acted as a dampner holding the to parts together.
The pieces are what created the "mouse turds".

The business end. These are the rollers that do the compress the internal piston to produce the actual injection.

Put her back together. Started right up after bleeding the lines. Has more power now.
