Good Motor to replace a KT17 SI?

[Brockwaykid]

Just looking for any good motors online that can be replaced for a KT17 SI. Anything reasonably priced, that is new, and would be worth the money. I have a 79 JD 317 and I am not sure if it runs. I have researched info on the SI, and I am just curious to see what would be a good replacement. Thanks, any help is apprectiated!

BTW, hopefully within the next few weeks I will get snow so my grandfather will move his plow, and ask him if I can get it runnin!

Tough question.
What have you found out when researching "SI" ?

How about some pics?

If I recall correctly the S1 means Series One (No pressure lubrication, splash lubricated). S2 means Series 2 (Full pressure lubrication with filter). What is the Spec # of this engine?

I had a 317 with the splash engine, used it one too many times transversing a hillside. One conn rod separated, but - believe it or not - the sucker kept running. But when I found out the price of a replacement KT17, I sold the now-one cylinder machine for parts. But if money was no object: John Deere 317 Outdoor Power Equipment Repower from Small Engine Warehouse

Hey guys, thanks for replying! I talked to my grandfather about the tractor today, and he said it will need an ignition, and a brake, which he has. I can order the ignition still? I guess my father blew up quite a few motors in it. Not sure what is in it now, so when I get it out, I will post pics, and try to get some info! He says it will run, but I dont know about that after its sat for 15+ years.......:laughing: I have to wash it first before I do anything...
I have a few pics, I can send them by email, Brockway760@yahoo.com
Also, where is the tag located? (serial #)?

Two tags; engine has one, tractor itself has one. Can't remember for sure, but try looking on the main frame of the tractor near the left rear wheel.

Thanks! Its in his garage corner, I could only get a bad view of the right side of the frame. It was too dark to see if there was anything on the motor.
Also, since it hasnt been started in a while, should I buy all the filters, spark plugs, and get some new oil for it? Probably should clean the carb. too. Been looking at some floatations for the back, and maybe new turfs for the front. None of the tires are flat, amazingly! Just a little soft. Its pretty rusty, where you would put your feet. I might just repaint it, and get it to run good, and get some tires.

I will be able to get a good look on Saturday!!

The spec number on the kt17 is actually on a stamped plate mounted on and engine shroud near the firewall. I replaced a blown series 1 with a series 2 short block, runs like a champ. Wasn't worth it for the money, but of course that wasn't the point. Check out weekend freedom machines website. Lots of good advice there on overhauling old green garden tractors .

I should mention that since the spec number is stamped on the shroud it's possible to have a 317 mower with a Series 2 spec # on the shroud but actually have a Series 1 engine inside. There are whole threads on weekend freedom machines dedicated to help you tell the difference between Ser 1 and 2.
