John Deere 310C leaking coolant at water pump

[LowPost42]

Right up by the pulley crankshaft, I get leakage when filling the rad. It needs almost two gallons of coolant mix to start leaking.

Please tell me this is just a tired seal and not a blown bearing requiring a new pump.

(Just kidding. Please tell me the truth).

Sounds like you know the truth. If you replace the seal, you replace the bearing at the same time. This would be a water pump to consider rebuilding, most are so cheap these days you just replace them, not JD. If there's a rebuild kit available, and you think you can handle the rebuild after a couple youtube videos, then try a rebuild.

i rebuilt 100's (if not 1000's) of pumps when i worked at a deere dealer.
30-40 minute job with the help of a press and the proper bearing/shaft driver

How long without the press?

 

[Delmer]

As long as it takes to build a press plus 40 minutes

A press of some sort is needed, you'll break stuff trying it any other way. A large vise might work, but it's easier with a press and an assortment of tooling for it.

I just remove the pump and have my deere dealer overhaul it. Cheaper than me learning to screw it up.

Caution: If you do not mount the pump correctly in the press to press the bearing out, you WILL break the water pump case.

I guess it can’t hurt to get a quote.

Turns out rebuild kits don’t exist for 40 year old machines in Ontario. Just bearings and impellers.

I guess I’ll pull the machine apart some more and get a 100% positive ID on the leak source.

Still gotta find a place to do the bearing (if I’m that lucky).

Individual parts will be available, maybe just not in complete ‘kit’ form. You will need the gasket, bearing assy and the seal kit. Go to JD online parts to look up the parts and see an exploded view. You can also give the part numbers to a JD ag dealer to check availability and price. They may have them in stock

They haven't sold kits in years, just individual parts. Still much cheaper to have it rebuilt (parts $177 US, includes the impeller) vs a new one ($900 US). Those prices are for the water pump without AC.

Take the seal to an appliance repair store, same type seal fits a lot of things.

deere used to supply a seal installer with the new seal.

$310+ shipping gets a new one.

Sometimes I wish I lived in America. It’s pushing a grand CAD to get it across the border and to my place.

Maybe someone here will let you ship it to their house. Drive there and pick it up.

What state is closest to you?

no deere dealers in canada? tractors and forestry machines as well as utility and const dealers use the same water pump
