C175 twin auto broken rod

[Domenic 11]

I have a c175 twin cylinder that has been good to me since I baught it but then all of a sudden out of no where it starts knocking, its a kt17 series 1 motor which doesnt have a fuel pump instead it uses a rod to splash the oil up into the cylinders. Im not sure if its that, which broke but Im wondering if instead of taking it all apart I should just buy a new series 2 motor which has the fuel pump and is more reliable from what I here

Series one and two both have OIL pumps but series two runs higher pressure and direct lubrication to main bearing rather than DRIP lubrication used on series one.

Rebuilding a Kohler opposed twin can be rather pricey. If you buy a used engine be sure you can hear it run in person before handing over the cash.

thank you i was told that the series 1 didnt have a oil pump but was obviously wrong. Ill look into getting a series 2 motor ive already saved a few on marketplace that I will go look at soon.

When you said buy a "new" Series 2 did you mean an actual brand "new" Series 2 that exist somewhere??? Or did you just mean "another " kt17 meaning a used replacement engine?

I'd be interested to know if actual new kt 17s are available somewhere? Thanks

I meant new for me im not sure if they make new one but I've found some used ones on market place that I might look at.

good luck -- i have both an S1 and S2 - - curiously, the S2 developed issues and the S1 is still ok -- we put a Briggs from a 1800 into the C175 replacing the S2 -- not sure yet what to do with the S2 ?? I want to get the S2 rebuilt but have not been able yet to find a shop in Hudson Valley, NY area to do the rebuild. Good luck with your project

Not all KT 17's are the same.  Wheel Horse spec engines have a thrust bearing to handle the axial load from the PTO.   Engines from other brands can be used,  but only with an electric clutch.

True statement and in reality very very few KT17s had the requisite thrust bearings.  You need to check spec#s

 

I have KT17s and I like them but after rebuilding a Magnum18 I would not overhauls any KTs Series 1 or 2.  Machine shop work is expensive (double cost of a single) parts are getting scarce and pricey and it is a lot of work.

Why not? They're just as easy as the cast iron singles (and easier than the K582) - I almost offered to rebuild it for him (provided they buy the parts and machine shop work)  but then I thought to double check just in case someone took me up on that and realized my barrel wrench grew legs and walked away some time in the last 15 years... (a must-have tool if you want to torque cylinder barrel nuts properly, but I DO still have my balance gear timing tool!) but I can still rebuild one just about blindfolded (other than looking up torque specs which were the first details to go from memory) as I used to rebuild kohler K series and magnums on an almost daily basis back in the 80's and 90's and don't think Ive forgotten much of the process - bare block up rebuilds... Of course I'd probably have the factory manual at hand anyways (always do, just to be 100% sure and get torque specs as I go) but KT series and Magnum twins were no more difficult to do than the single cylinder K's and M's were. (I hated the commands though, and by the time Courage came out I was out of the rebuilding business.)
