IH 330 Utility Time to make it Run

Walmart, Kmart, Sears, Sams Club, Advance Auto, Auto Zone, Napa, CarQuest, National Tire & Battery, GoodYear, Firestone, Pep Boys... That isn't even considering any farm machinery dealers that are probably in your area. They don't have to be CaseIH dealers, either. New Holland, John Deere, Massey Ferguson, AGCO...

Just measure the battery you have, and take note of the type of connections it needs. Take your tape measure with you to any of these places, and start measuring up likely candidates.

The steering wheel is only going to come off with much blood, sweat and tears. There's no easy way, as it's certainly rusted on. A gear puller, an impact wrench, lots of PB Blaster, and the patience of a saint is the only way it's coming off there.

You need to use a good puller on the steering wheel and use a torch to heat the hub while putting a strain on the old steering wheel with the puller.

Your local auto parts store probably has a replacement oil filter. Look on the old filter for a p/n number. I would use 30wt oil and keep using the same oil if you know what's been used. If you've been using non-detergent oil I would stay with that. Using detergent oil would loosen all that sludge and may block your oil passages in the engine block. Your shop manual should give the oil capacity for your engine. It's probably 6 to 8 quarts, but check your manual.
