Re: 440IC crawler had 3 push rods

I have had more of these apart than I can count. I've never had a pushrod go into the pan, so I'm going to say it's at least a little difficult.

Re: 10W oil

Readily available many places. Nowadays it is called AW32 hydraulic oil. Pretty much every farm fleet store should have lots on hand.

Re: Rear PTO and 3 Point hitch questions

Very expensive, very hard to come by, and you would need a loader valve that has an auxiliary circuit to run the 3PT hitch.

Re: Adding aftermarket hydraulic winch

You will need an open center valve with over 20GPM flow capacity, and around 2250PSI, but verify that. Keep in mind, you will have winch, or you will have loader, but not both at the same time.

Re: Splitting a 40 Crawler

Re: weak right steering clutch on 350

Unless you are mak8ng a 80 hour a week living with it, a new set of clutches should last your lifetime and beyond. Soooo, how l9ng do you want to be irritated by the clutch/clutches?
