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

Thanks Sam.

Did you have Jeff make you a fan support plate? It will center the fan better than the shoulder nuts that the factory uses and it adds support to the center of the fan.

I do not believe he did?

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.

I've sent Jeff the drawing so give him a shout, he should be able to make one for you.

Looking good Mike!! Keep up the good work!!

Thanks Sam, but I may have found an acceptable solution.

Thanks!

I did not have much free time this afternoon. A bunch of that was spent tracking down the belts and new fuel lines.

I did get the engine adapter plate installed (for the CV drive shaft). I drilled and tapped the input shaft on the pump, then installed the pump adapter.

The CV drive shaft did not include the fan, but it did have the pump adapter off of the 1864. Splines are different than the 1772.

I believe that pump adapter can be altered to make a fan reinforcement plate, for the 1772 fan.

I'll see if I can get it in a lathe, time will tell.

Something is wrong, the pump adapter in your 1st pic should fit the pump shaft on a 1772. I need to see a pic of your pump shaft. It should be a 5/8" nine spline shaft unless a PO has screwed with it. Every Super I have seen has a 5/8" nine spline input from the 982 up to the 2284. As far as trying to cut that pump adapter don't even waste your time, it is HARD. But if you want to try it let us know how it works for you LMAO. Pic is of one of the adapters I used to make on a 1772.

Edit: Thought you said you didn't get the fan? You have the fan in your pics!

I just eyeballed the splined end of the 1864 pump adapter, it may be the correct spline size, but the the flange (side where the drive shaft bolts to it.) length appears to be shorter than the one you designed? I'll take a picture of the pump input shaft this afternoon.

As far as chucking the adapter from the 1864 up in the lathe, I have a different idea that may work better. But all of our tooling is inserted carbide, we cut hard weld, aluminum bronze, titanium, whatever.

But cutting out (2) plates on the waterjet, to sandwich the plastic fan may be a better idea. The O.D. of the plates can match the I.D of the fan recess, then just use the bolt pattern to keep it all concentric.

The fan shown is the one off of the 1772, drive shaft. The bolt circle on it is smaller than the 1864 adapter bolt circle.

The drive shaft I bought from the 1864, did not come with a fan.

Sams adapter flange should be the same distance from the end of the pump shaft to the adapter face. However it has longer splines to engage the whole pump shaft unlike the stock adapter, and the flange on Sams is thicker so it can be threaded unlike the stock setup.

Okay, I think I understand. I'll take a closer look this evening.

Thanks.
