Allis 917 rings

Recommended Posts

tillerman
Hello once again everyone . I have a 917 that is smoking pretty badly. I have overhauled several one cylinder Kohler engines and I have only put rings in a few of them. I was thinking about putting only the rings in this one as it is the only time this engine has been opened up. how hard would it be to do this without taking the engine off the tractor or is it impossible to do this. The tractor runs really well but really needs some attention shortly. Thanks,Richard

I just rebuilt a KT17. It is virtually impossible even to get the shroud off the engine to pull the heads with the engine in the tractor. It really doesn't add a ton of work to take the engine out. It also allows you to really clean the engine up while you're at it.

I have to pull a kohler engine out of a 917 today or tomorrow. Do you unbolt the drive shaft first or is it easier after you get the four bottom bolts out ??? This tractor is interesting because I am used to the front belt outputs like on the sunstar. The front shaft on the 917 is just hanging there looking a bit rusty...

I unbolted the engine first to give me some wiggle room. Removing the gas tank and battery would make better access to the driveshaft.

Thanks for the replies. Okay I will remove the engine. Now what has to be removed to take off the barrels that contain the pistons. I have the manual for the engine but it only goes through the procedure to tear the complete engine down. I will do this if I have to but I would like to keep everything intact except the heads and barrels. Thanks , Richard

You have to remove the cooling shrouds, intake, exhaust and you should then be able to remove the heads and cyclinders. The cyl are already stamped # 1&2 but you'll have to make reference marks to the heads. I bought all my parts from www.opeengines.com really fast shipping and the prices were good too.
