Is the tractor's pump you are referring to mounted to the engine or the rear of the tractor?

Hi Chris,
Does your backhoe run off the tractor hydraulics using quick-connect fittings, or does it have it's own separate pump and reservoir?

Me too. I'm looking for a used mini-excavator bucket that I can cut down.

That just looks wrong, but I must admit very clever. Those OEM wheels must cost an awful lot to go that route.

As I expected. My guess now is that it's the bull gear shaft – the one that the sprocket bolts to. Good luck.

If you go with the Delco Si series you will also have to replace your ammeter with a voltmeter. Sorry, forgot to mention that. For the pulley size, get the smallest you can for a B-section belt. It will be one of these two:

The wiring is simple and straightforward. You may remove your existing voltage regulator. Here is a simple diagram.

The answer is yes, but it's not exactly “plug 'n play”. First must know the amp rating of your old alternator. Most of the alternators that come on these tractors are nominally rated around 14 amps, which is almost at the maximum ampacity for 16 gauge wire. If you go with a larger capacity alternator you will have to increase output wire size. Most people upgrade to a Delco 10Si or 12Si “single wire” alternator. If you want optimum performance from a new alternator that was meant for automotive applications you must also replace the pulley with a smaller one.

Just out of curiosity, what is your temperature gauge reading when you get the low oil pressure?

I know it sounds counter-intuitive, but running without a thermostat can be a bad idea, especially when the cooling systems are marginally designed. What can happen is the coolant doesn't spend enough time in the radiator core to allow it to cool properly, so the end result is approximately zero ΔT. Optimum ΔT is around 12°F – 15°F. Install a good 180°F thermostat.

Glad you got it running again Doug.
What Rich said.
These tractors must have impeccably clean radiators since they don’t have oil coolers like some high end equipment. Give your radiator fins a good careful cleaning.
Many people, including myself, install furnace filter media in front of their radiator, works like a charm.
