I have an old (1970?) Kohler K141, which is not doing real well.
There's an auction coming up which lists a number of small engines (none
Kohler) in that hp range.

Are these engines sometimes/ever interchangeable? If there's a
reasonable possibility, I'd look into more details; but, if every mfr
and model is unique, I'd rather not waste my time.

Thanks,
George

depends what the engine goes on.. id rebuild that kohler if i were you

For a lot of applications there is quite a bit of interchangability. The
main variable is the output shaft size and type, there are a number of
variations there from straight shafts with key ways to tapered shafts to
threaded, etc. Outside of that for a given HP engines from different
manufacturers pretty well match on form factor and mounting points in
most cases. The closer parts of the item the engine goes in come to the
engine the more potential there is for interference with parts of a
different model engine. Best you can do is take the relevant
measurements and go measure possible replacements to see what will fit.

In some applications, it's nothing more than bolt circle, shaft
size & type, engine rotation, and shaft orientation (vertical
versus horizontal).

In other applications, it's _real_ picky. I'd hate to have
to substitute a different motor for the 12HP Kohler in my lawn
tractor. It has to fit inside the cowling, and have appropriate
"points of contact" for all of the various add-on bits, clutches,
drive shafts etc.

Kohlers are _good_ engines, and parts are still available even for
the very old ones.

I'd make a serious attempt to rebuild it first, before chancing
a "modern" (all too often "throwaway") substitute.

If rebuild fails, you'll want to call Kohler with your model and spec
number and see whether they have a drop-in replacement for it.

Kohlers are sufficiently well-respected, you can buy "rebuilt"
motors as well.

[There's a thriving group of folks who like nothing more than to soup up
and race/"tractor pull" Cub Cadet tractors, supported by a network of
people selling performance enhancing accessories, know-how, and
including reconditioned (and souped-up if you want) motors. Yes, you
can rebore my old 12HP Kohler to put out 20HP, as long as you remember
to put extra bracing around the block/cylinder to prevent the rebored
cylinder from launching into orbit. I'm just using it to mow the lawn
thank you very much.... Doubling the power of a Homelite weedwacker
motor, tho, made more sense to us ;-)]
