Thank you FrankF3 for helping me find my new (to me) 1772!

[MWShaw]

As promised pics of the pump input shaft;





And the two adapters; I was wrong, the spline size is identical between the two.








This shows what I am trying to do, to re use the fan from the 1772, cut out (2) pcs of 2.0mm sheet metal on the water jet. The fan will be sandwiched between those;







Difference in the bolt patterns;

[MWShaw]

Got the CV parts out of the parts washer, and began to re assemble those;





Everything was clicking right along, until I tried to finish the installation. It seems this shaft may not be from a 1864? It is about 2.5" too short



I pulled back out, it is 18.0" long, possibly Sam will chime in and let me know if this is in fact from a 1864, or a different tractor? Or I'm really missing something here.

[MWShaw]

Well, I do not believe that the drive shaft I bought was from an 1864. Cub parts says a 1864 drive shaft should be 20.38" lg. This one is only 18.0" lg

Sounds like it's from a 1541. Who did you get the shaft from? Also you do not need to sandwich the fan between 2 pieces of steel. The fan plate I mentioned is one piece of aluminum. It centers the fan and holds the fan against the rubber CV boot. I like to keep the weight down that is hanging off the pump shaft.

Shaft came from a member here. Not a supporting vendor.

Thanks Sam.

To be honest I have not even opened the box he sent. I just asked for the adapters, so I am assuming that is all I got.

I was not aware that you had designed such a plate, therefore I did not know to request it.

Machined some up Friday night and mailed two to another OCC forum member this morning.

Nice job Jeff!

I've been giving your contact info out!

Hopefully you get some O.T. in on Cub parts!

This drive shaft conversion is a slick deal, much better than rag joints.

It think I reached a milestone, the 1772 is back together and it runs.

Upgrades are;

1. New filters and fuel lines. (tank was cleaned out as well.)
2. New glow plugs.
3. New belts.
4. Glow plug relay mod.
5. Gear reduction starter.
6. Mini Denso alternator. (that may have to come back off, because I don't think the turbo will fit with the alternator there, but that's a story for a different day!)
7. New battery cables made from 0 gauge cable.
8. CV drives shaft upgrade.
9. Valves adjusted.

Thanks for all the input / help along the way.

Turbo huh?
Might as well add propane injection also!
