Recently purchased a nice 917 without an engine. I understand that model of Kohler was not reliable, what is recommended as replacement?

The 917 & 919 used the "KT" series motor. The original ones, also known as the series ones, had two major flaws. The connecting rod bearings were not pressure lubed, just splash and the oil pump was located to one side of the block. I can't recall which side right now but if you ran across the side of a hill the oil all ran to the other side starving the pump for oil and you would soon have a ventilated block. Kohler rectified these problems by coming out with the series II "KT" motors that drilled the crank and pressure lubed the connecting rod bearings and relocated the oil pump to the center of the block in a little sump so you could run side hills and not lose oil. The series II motors then were almost bullet proof. Back in 2000 I bought a 919 with a blown engine and only 400 hrs on it. I bought a complete brand new series II motor from Jack's small engine warehouse in Nebraska shipped to my door for $1500. Was a lot of money at the time but I now have over 1000 hrs on it and have had zero issues with it. Other motors such as the magnum or command series will fit but not without modifications. Try and find a series II and you won't regret it. Sorry so long winded but hope this helps. Don Jr.

How can I tell difference between series 1 and series 11 engines? Have a lawn mower salvage yard close by and will go on a search/rescue mission. Thanks for info!

I have a 917 that I bought at an auction when it was about a year old, but I don't remember when. It's a 2 cylinder opposed. A few years later I saw a new, I think 917, that had a V-2 engine in it.

Oil filter will be one way to tell.

My 917, has a KT in it and I have had zero issues. It mows 1.2 acres each week. I have a few hills but not much. I think it’s a 1983. I bought it in 1988. The owner failed to get the front seal replaced when it began leaking worse. Shortly after it threw a rod out the side due to no oil. He traded it in on a Simplicity and I bought it when the dealer installed a brand new KT in it. I have repaired the deck several times but it has been a very good tractor, the KT has been rock solid.

I have two KT17 series 2 engines. Mine way series 2 on the shroud decals. Both run awesome. One has 2000 hrs, the other unknown. I really like the way they sound. They have a unique sound when working even a little different than an Onan.

Where are you located in Oh. and how much for the better of the 2? What is included with the engine? Did either of them come from an Allis or Simplicity mower?

My 917 came with an 18 horse in it but the guy threw the original engine in with the deal. Problem with the 18 is ya gotta take the damn engine out to put in a new ignition module! The original has points up on top of the engine making ignition a breeze! -- I still want to rebuild the 17 ---the good motor and put it back in so I can get to the ignition without taking the motor out all the time! ---- repower aint the answer folks!!

What does everyone think of the 18 hp Kohler that was in the 718 Allis lawn mower

the Honda V 18 HP is a good replacement but a little pricey . Think the Harbor Freight V engine would be worth a try

ac fleet i am with you all the way and right more than ever .. at least the kohler stuff that is produced in china has dealer support. any one that thinks honda parts allfit on hf engines havent tried to match up or find very many honda part numbers for a hf engine, especalily when you order one in for a customer and its wrong you just wasted an hour out of your labor plus freight cost of the part and you still have a customer that doesnt have his part

I have had good luck with all of the Kohler motors that I have. -----The old ones are the best ones --- newer ones are o.k but could be made cast iron and not luni, so dont know how long they will hold up,--probably bout as long as a Tech! --I have 3 of them on tillers and they are too light in weight, messes up the balance.
