I just purchased a model 100 Davis loader and need some info on hooking up the pump to the engine crankshaft pulley, It came with a 12 inch shaft thats splined on one end which I'm thinking attaches to the crankshaft pulley somehow but I must be missing something. anyone have any pictures or info they could send..
Thanks.

Welcome To TF jmck70eb!!

Sounds like the setup I had on my 8N for the plow blade. There is a flange that blots to the front pulley, that the shaft fits into. Now I belive that you need a new pulley also. I think the one that came with the tractor is cast, and you would need a steel pulley to mount the pump shaft on. Who knows what is on yous now though, after all these years ANYTHING could have been changed.

Yep, that looks like what I need. My pulley has four 1/4 inch holes taped in it so I need something like what you've got that splined in the center to accept my stinger shaft.
If anyone knows where I can buy parts like that let me know.

Thanks for the help!

Crank pulley

The Pulley on mine has no holes in it for a bolt up flange instead the center is threaded. The female receiver for the pump shaft was welded to an old chain drive gear. The problem I'm having is it's stripped (probably due to being out of alignment so bad after some fool dropped a plow on it!!) Can anyone tell me how this pulley is attached to the crank?

It is a "Vickers" vane pump with a keyed shaft on the pump. There is an extension shaft to go through the center of the king pin to the crankshaft and that end is splined.

Sounds like mine. Did/does yours have a flex joint in it? If not probably why it is all stripped out.

The pulley should just be bolted onto the crank. You would need to temove the front engine mount to get to it, but I would probably replace it with the correct steel pully, with the right attachment hub for the pump stinger shaft. I think in the long run, you would be better off. BTW good time to change that fan belt:D :D

Found it!

I found the part I was looking for today, I called up a Tisco Dealer and he can order the adaptor for around $38.00. I've got four 1/4 holes taped into my harmonic balancer, 4 bolts go through the adaptor in metal sleeves that are mounted in rubber bushings to absorb shock loading and it turns out that they made 2 different types of adaptors, one will accept a 6 spline stinger shaft and the other will accept a threaded shaft, I've heard that the threaded shaft may be a left hand thread but haven't seen one to prove it true but it's a good thing to keep mind if you ever go to unscrew one of these.

Thanks for all the input..

Almost done

I started this project around the first of May and it's starting to come together. I sandblasted everything and welded up a few cracks which weren't apparent until it was blasted then before painting I installed a new clutch. All thats left is to paint and mount the rear axle loader brackets then I can hang the rear fenders. I bought one of those cheep non OEM style grills for the front and figured I'd modify it for the loader stinger shaft to fit through by welding a 4inch ring to it then cutting out the center. I'll post a pic when the projects complete.

Thanks for the interest..

Good job. Did you perform a complete overhaul, including electrical, engine rebuild, tranny seals. PTO seals, hydraulics etc or was all of that ok and you just did a repaint? It looks really nice. What parts did you replace? It appears like a early 8N model 48-49ish --- you convert to 12V?

Projects

This is the first tractor I've owned as well as worked on and my intent was to fix it up as a working tractor for brush hogging the back field as well as using the loader for light yard/road maintenance. The engine was running good after the tune up so for financal reasons I opted to hold off on a enging rebuild for now figuring I can do it during the winter months if i dont like it's performance. The hydraulics seem to work ok but the real test will come in a few weeks after I buy that brush hog. Some of the new parts include

Tires
PTO Seal
Axle bushing
Spindle Bushings
Hub seals
Oil pressure gauge
Volt gauge
Shifter boot
Tie rod boots
Steering wheel
Ignition system
Key switch
Light switch
Carb Kit
Air Cleaner Tube
Manifold
Drawbar stay Chains
Frost plugs
Water Pump
Radiator
Grill
Converted to 12 Volt charging system
Upgraded to a adjustable steering box


My last project was a 1970 Frod Bronco,
