Oldskool 6,582 #76 Posted March 11, 2020 Ok guys. I may have found an engine. Kohler 14hp 321SA. It's in an old Case. Is this going to fit the GT? I read somewhere the "S" is for special sump. So just not sure. Also is the output shaft the same dia? Share this post Link to post Share on other sites

The "S" tells you the engine is equipped with an electric starter. Find out the Spec. # of the engine you are looking at and one of us can look it up to see what you are getting into. 1 Share this post Link to post Share on other sites

Also curious as to how many lbs per sq. in the compression should be. Not looking to buy another basket case engine Share this post Link to post Share on other sites

Not looking to buy another basket case engine Many Kohler engines can only be tested by leakdown. The ACR prevents a compression test from working. 1 Share this post Link to post Share on other sites
Oldskool 6,582 #80 Posted March 12, 2020 Thanks. Wasn't thinking the older engines had the compression release. Guess I'm borrowing a leak down tester Share this post Link to post Share on other sites

oldredrider 2,547 #82 Posted March 12, 2020 If the engine you found is a K-321AS, it will not be a direct fit. It would have the narrow base oil pan and use the cradle mount, like a late 70's thru early 80's Wheel Horses. 1 Share this post Link to post Share on other sites

oldredrider 2,547 #84 Posted March 12, 2020 You would need the engine spec # or actual measurement to know. 2 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,503 #87 Posted March 12, 2020 Kohler made the K321AS-60410 for Ingersoll Equipment in 1983 Kohler made the K321S-60125B for Wheel Horse in 1970 The serial numbers are used to determine the year of Kohler manufacture. Garry 1 Share this post Link to post Share on other sites

pfrederi 17,147 #89 Posted March 13, 2020 Not directly if it is the small oil pan, and you can't just swap pans, the base of the block is different . Look at the pinned post in the engine forum Identifying big block Kohler blocks. I will take a couple pics later of how i put the AS style engine on an Electro. 1 Share this post Link to post Share on other sites

Look at the pinned post in the engine forum Identifying big block Kohler blocks. I will take a couple pics later of how i put the AS style engine on an Electro. I just put eyes on the engine. Now I see the difference. It looks like I might be able to modify the mounting plate to make it work. Any body know if it's going to be troublesome getting the hydraulic pump off the shaft?

pfrederi 17,147 #91 Posted March 13, 2020 There is no engine plate on a GT14. The frame rails are further apart which will make getting the drop down part of oil pan in place easier than on the Electro but may cause a slight alignment issue with your drive pulley. For spacers I used the ones that came with K181 engines on shaker mounts. plus 3 washers. What hydro pump are you talking about? 1 1 Share this post Link to post Share on other sites

pfrederi 17,147 #93 Posted March 13, 2020 Can't help with pump removal but you may have a bigger issue. The crankshaft is kind of short... Share this post Link to post Share on other sites
pfrederi 17,147 #94 Posted March 13, 2020 Also doesn't look like it is drilled for the electric PTO \This is the WH spec Crank 1 Share this post Link to post Share on other sites

To top it all off I haven't heard it fire yet. I think I will keep looking for a differant engine. Thanks for your time and the info. 1 Share this post Link to post Share on other sites

Go to Kohler engine site for parts. https://www.kohlerenginesparts.com/ Look up the spec number in question. get the crankshaft part number then go to eh manuals section here download the crankshaft reference look up the crank number and you can see the various measurements. 1 1 Share this post Link to post Share on other sites
Oldskool 6,582 #97 Posted March 13, 2020 @pfrederi Again, thanks for the info. Looks like I may buy the Case anyways. It has a hydraulic pump on it along with a piston and valve. All useful things for future projects 1 Share this post Link to post Share on other sites
Pullstart 59,744 #98 Posted March 13, 2020 @Oldskool you could just simply pop a 22 hp Predator in there... @Aldon didn’t struggle too hard with it! 1 1 1 Share this post Link to post Share on other sites

WildmanC120 613 #100 Posted March 14, 2020 @richmondred01 always has some engines for sale. Rebuilt and ready to go. A predator 22hp swap is always fun too. I have one on my C-161 and its great. 2 Share this post Link to post Share on other sites
