Since I have the engine apart on my K161 that's in my Bolens I got to thinking about the K160 that's in my Bolens Ride-a-Matic. Since I plan to restore it I will need to take apart the engine and possibly re-Ring it because it does smoke a bit during start up. There doesn't seem to be much information or parts out there for the K160  :anyone:

 

My question is what are the main differences between the two?

 Sounds like a special application..  Here's a screen shot of the Identification information from the K-series manual:

From that chart it would appear that the 161 would have 1 cylinder and the 160 wouldn't have a cylinder   :D   Really, I think its more of an age issue. I don't know what the exact differences are but I've always heard parts don't interchange. Being as how you have the 161 down you might as well pull the 160 down and document the differences.

This is only a guess, :D

it may be a engine that Kohler only produced for Bolens, but it's really a K161?. I see it a lot in my industry (HVAC).

Company (A) will order 25,000 controls from a major supplier for new units and for replacements, but with company (A) "special" part #, they do this so they are the only one that has the "factory" part # controls,(costs more) but it's not all that "special".

One company paints a item we use black, it's the same item that we can buy from them in green, if I want a black one, back to OEM.

It sounds possible, but I think they were also used on the Wheel Horse tractors.

The majority of the K160's seem to be on Bolens though...

The 160's seems to be an oddball model, if you do a google search you dont see too much info or parts on them....

Wheel Horse did not use any K160 engines. Their first 7 HP engine was a K-161S un the 701 in 1961.

 

Kohler's part listing groups all the K90 and K91 engines under their listings for K91 engines. The spec number on the K90 models leads you to the proper part number.

 

It is queit possible that they group the K160 specs in with the K161 specs, but that is only an assumption on my part.

. There doesn't seem to be much information or parts out there for the K160  :anyone:

 

My question is what are the main differences between the two?

 

Brian:

 

I have a manual for the K160 engine.  ...It has a printing date of October 1953.  ....It shows parts & part numbers, but there is no reference to any SPEC numbers.

 

I also have a March 1971 parts book which is for K141, K161, & K181 engines.  ....This has a list of SPEC numbers, which is used to find the Variation # for a given group of parts.

 

If you provide the SPEC numbers for both your K160 & K161 engines, I can see if I can spot any obvious differences.  .....I suspect, but can not prove, that the K160 & K161 are identical, but I'd be willing to bet that most parts will interchange.

 

If you have any specific questions about part numbers for either engine, I will try to help.

 

One thing I just noticed in the books is that all K160 engines had a 2-7/8" bore.  .....Early K141 & K161 engines had the same 2-7/8" bore, but later K141 & K161 engines had a 2-15/16" bore which was the same bore as all K181 engines.

 

Stroke length on the K160 is 2-1/2", but I haven't found the stroke length yet for the K141, K161, & K181 engines.

 

p.s. - did you notice the time of this post?

The stroke on the K141 & K161 is 2 1/2". On the K181 it is 2 3/4".

The Ride-a-Matic is stored in the shed with a Versa-Matic and rear tine power tiller blocking its path

Will See if I can squeeze my way through and get the numbers off the ID plate :D

 

And what were you doing up at 3 in the morning Bruce?
