D17 4cyl 3.7 Tune Up Suggestions?

Hello, I just bought a 1966 Allis Chalmers D17 IV Gas with loader. The previous owner said it had been sitting for a year or so and within the last five years he'd only used it a few times. The tractor will fire with a few squirts of starting fluid although doesn't want to keep running. So I went and ordered parts for a tune up, we'll start with that and see where it gets us. I figured I might as well get on here and see if anyone had any experience and relative suggestions regarding bringing this good old girl back to solid working condition besides or in addition to the items I'll list below.

Today's Napa Order...

Cap: $11.99
Rotor: $17.99
Plugs: $2.69 x 4
Wires: $32.99
Air filter: $41.89
Oil filter: $8.29
Oil: I'll pick up with my parts order tomorrow any suggestions?

Points: $ 17.99
Condenser: $3.29

Fuel filter: Clean out small plastic separator bowl is there another?

Fuel: Drain and fill gas.

Carburetor: Disassemble & Clean?

Hydraulics: Top off fluid, Order filter or filters?.. I knew I forgot something!

Grease Zerk Fittings.



Anything anyone knowledgeable pertaining to this tractor noticed I didn't mention and would be willing to add would be appreciated.

Replace all the soft fuel lines with new. Ethanol gas eats old rubber. File the points . Give the carb a couple wacks with a screwdriver handle to unstick the float. Check out the entire air inlet system. Bugs,mud daubers and mice get everywhere. Cheap and easy first. Check the battery cable connections and shine them up.

I appreciate everyone's input and welcome, It appears I don't know how to show who I'm responding to specifically. None the less Thank You All for your time responding. We'll see how it goes tomorrow.

Air filter oil trap on a D17IV?

*Oil bath with mesh air cleaner.

No I'm talking about and oil bath filter. Funny NAPA did send me a traditional air filter, I figured they were just mistaken. I'll check the serial number and report back.

Update...

Today I went and picked up a carb rebuild kit although the only items I really needed was a new float and a new glass bowl separator gasket. Neither of which by the way come in the carb rebuild kit. Since I was only about an hour away from Tony's Tractors I decided to stop by and pick up the items which he did have in stock and introduce myself. Anyhow as I said I ended up not using the rebuild kit. I did remove the carb, took it apart again cleaned the body, the jet, and passageways. I reassembled again reusing the old gaskets, they were still very much usable, they don't leak and they don't appear to be breaking down to any discernible degree. Deciding not to continually fight with what I assumed to be the root problem that being the gas tank or more specifically the remaining contamination residing in the gas tank. I decided to take it off the tractor, I repeatedly sloshed it around and quickly dumped out incremental amounts of the previous fuel & carb cleaner mixture attempting to incurage particulate contamination to be picked up and thrown into suspension just long enough to be carried away while dumping. Afterwords I again blew both fuel supply lines out with break clean, cleaned the small screen filter and this time put in the new gasket for the bowl separator after scraping out the rest of what was left of the old one.
Put everything back together fired her up and let her run for a hour plus this evening... No bogging, no hiccups, no signs or sounds of anything except the obvious utter delight of a previously extremely neglected good ol tractor very appreciatively roaring back to life!

Also while I was at Tony's I had a picture of my serial number D17 32558 and his allis chalmers books confirm as some of you imagined it is not a 1966 Series IV as advertised by the previous owner, instead the serial number makes it a Series II 1961 I believe.

I'll try and figure out how to get some pictures on here when I get some more time.

Thanks for the help guys.

C&D,

Update...

Today I greased her all up, had to use the piston and marvel mystery oil on two zerks of the bunch, one on a king pin and one on the loader but that worked and she's nice and lubed! Got the gear box filled up with 80/90w & hydraulic oil topped off. After that I figured it's time to drive her around the farm and see how well she would do in all gears. Well in the back of my farm there's a switch back dirt road that goes up about 75' in elevation that's in excess of a 15% grade climb. I drove back there in fourth gear which really gets up and moves by the way... Approached the hill in third gear and decided to go for it about 80% throttle. She drove right up without the slightest care in the world in fact almost sounded so good I'd aware She was more stoked than me to be back alive and ready for work!

Well that's when I decided the calcium ballast leaking out of the tube and rusting out the left rear rim wasn't going to stay like that any longer.

I forgot to take a before pic of the hole in the rim after taking out the tube.

Here's the tube...



After removing the tube a hole the size silver dollar crumbled out directly around where the calcium ballast had been leaking past a faulty valve core and slowly seeping out of the plastic cap for some time.

Here's after welding in some 3/16" thick flat bar.







Took the grinder with cup wheel and cleaned up the entire inside of the rim, extra thoroughly where the bead will seat. Also took a hand wire brush and small pry bar and cleaned all the deposits off the tire where the bead will seat.



Tomorrow morning we'll get the new tube put in and tire back on.

Nice job patching. How much of a bigger was it to break the bead?

I'm about to do the same :)

Looks like y?oh are making excellent progress! These old tractors are very satisfying to work on. Nothing like getting them running and working as they should. Enjoy your successes!
