Crazy8 55 #1 Posted April 25, 2023 First time Wheel Horse owner. Never knew there was a whole community out there dedicated to WH's. Very cool! I recently picked up a used WH C-81 or maybe it's a C-121. Can't really be sure. There's a tag riveted to the small panel in front of the shifters with the ammeter in it. The tag No is 91-08K802-29819 with s/n 617. That tag no would indicate it's a 1979 C-81 with an 8 HP Kohler. The decal on the side of the hood says C-121 8 speed but that has clearly been layered over at least one previous decal. The engine has no tags left on it, or maybe they are buried under 6 coats of paint. The only way I figured I could verify the engine is by bore diameter, so off with the head! Bore measured 3.374 so I figure that makes it a K301 8 HP, would that be correct? After cleaning up several generations of melted wires and butt splices galore I was able to get the electrical system functioning pretty well. When I had the head off of it, it appeared in great shape internally. No signs of burning oil, very lightly carboned, valves look great. It actually had good oil in it too. Pulled the fuel tank, dumped out the sludge, cleaned it out real well. Reinstalled it with new fuel lines and inline filter. It looked like the fuel pump had been replaced as it was a plastic body. Put some gas in the tank, siphoned some fuel into the line and stuck it on the pump. With just a few cranks it fired right up without even pulling the carb off! Next thing I pulled the dip stick on the transmission and it had oil on it!!! But of coarse that was just the 1/2" of oil that was floating on top of 1/2 gal of water. No boot at all at the base of the shifter. I suppose that's where most of the water was getting in. It was already apparent that the left side axle seal was leaking so that's on the list. I filled the tranny with a little bit of everything I had on the shelf. Mostly auto transmission fluid and a little motor oil. I'll run that around the yard a few times to flush things out and then put the 140 gear oil in it. Of coarse the stuff I was pouring in was also pouring out that axle seal as fast as I poured it in. All in all for the $450 I paid for it, with a solid engine, A heavy duty rear hitch and excellent sheet metal and tires, I'm a happy camper. Bought it just to move my boat around the yard and this beast will do that without even breaking a sweat. Very glad to have found this forum and look forward to sharing in your WH experiences.

Crazy8 55 #2 Posted April 25, 2023 Correction, I meant to say based on bore diameter it would be a K301 12 HP 5 Share this post Link to post Share on other sites
WHX?? 48,813 #3 Posted April 25, 2023 (edited) Crazy. You found the right place for your info about your horse. Only thing you need to know about us is we like . You need manuals we got em. 15 hours ago, Crazy8 said: Never knew there was a whole community out there dedicated to WH's. Here too back in '15 when I joined. Sounds like you got a handle on treating it right. You mentioned ATF. Is this a hydro? Nevermind you also mentioned shifter boot. We are going to have to have you check the outboard transmission bearings if it leaks that bad. Edited April 26, 2023 by WHX?? 3 Share this post Link to post Share on other sites
953 nut 55,155 #4 Posted April 25, 2023 Great introduction and glad to have you with us. Before you replace that axle seal you probably should jack up the rear-end and see if there is any play in the axle. A bit of in/out is to be expected but up/down or front/rear indicates a bad axle bearing. 2 Share this post Link to post Share on other sites

wallfish 16,994 #9 Posted April 26, 2023 You seem to have a handle on things so far. There are few us close by to Winchendon. We typically run in to each other at some of the local engine shows.

gwest_ca-(File Mod) 11,039 #13 Posted April 26, 2023 Added your numbers to the serial list. There is a mistake in the 617 build date and not the first time it has shown up. It should have four digits and is the Julian build date. Click on the fuzzy picture 1 Share this post Link to post Share on other sites
Crazy8 55 #14 Posted April 26, 2023 Wow what a welcome! And thanks for the input. I thought I had found a fair bit of info on-line for manuals and such but Wow it looks like Gwest sent me a Mother Load of info. I will definately check that axle bearing for play. If it's bad I suppose the tranny needs to come out and you have to split the case to replace it?? Believe it or not the one thing that is being a pain right now is the throttle cable. I can't seem to figure out how it's supposed to be routed to the engine or how it's supposed to connect to the pivoting lever thing which is connected to the govenor by a solid rod with e-clip. If anyone can shed some light or pictures of how it's supposed to look that would be great, and yes I need to be better in attaching pics. I'll get some today. Oh one more question for now. Can you share a short list of go-to web sites or other sources for parts? If I go to some of the OEM type sources the prices are CRAZY. I found Isavetractors.com. Norman does a nice job with his videos but I guess he is mainly a source for engine parts. I do have a key switch, air filter and set of points on the way from him. 3 Share this post Link to post Share on other sites

Yeah you will have to remove the transmission and break it open. Is demonstrated in your first post that you should be capable of identifying the opposite ends of a wrench 🔧 or screwdriver 🪛 so you would be fine doing that job. Plenty of tutorials. Several of us have been into a few transmissions over the last few years. 9 minutes ago, Crazy8 said: OEM type sources the prices are CRAZY About the only thing I buy OEM on purpose nowadays is the case gasket for when you split the transmissions. Other than that I have a long standing habit of trying to identify a part number and finding that piece for the least price I can. Sometimes local brick and mortar. Sometimes online. @squonk is a great source for NAPA part numbers if you have one of their stores handy. A quick search on this site and you will often find several part numbers of what it is you're looking for. isavetractors is a GREAT source of information... and I like Norm as a person but his prices are rarely the lowest. 3 Share this post Link to post Share on other sites
wallfish 16,994 #16 Posted April 26, 2023 (edited) Correct, trans would need to split to replace bearings. Cable swivel to connect wire to that lever. Yes, parts cost are getting crazy. http://www.psep.biz/index.htm Isavetractors is a great source for quality parts. Especially their replacement carbs Edited April 26, 2023 by wallfish 2 5 Share this post Link to post Share on other sites

Crazy8 55 #21 Posted April 26, 2023 Wallfish, excellent pic of the throttle cable connection. I kinda tried to connect it coming from the right side like that but I got the reverse action from the throttle lever. When I raise the lever at the dash (indicating increased engine speed) the core wire in the cable pushes out the end, which pushes the pivoting lever in a counter clockwise direction moving the carb to idle position. Do I have something messed up or do I have the wrong throttle lever unit in the dash? Share this post Link to post Share on other sites

Crazy8 55 #23 Posted April 26, 2023 I checked that left side axle bearing and it's definately blown up. That's probably from running with water in the tranny. If the shaft is a mess what are my options for a replacement? 1 Share this post Link to post Share on other sites

If the shaft is a mess what are my options for a replacement? No worries. Really. All the bearings, seals and gaskets are available from several sources. Good used axles can be had from Lincoln at A to Z Tractor in PA. You're good. 2 Share this post Link to post Share on other sites
Crazy8 55 #25 Posted April 26, 2023 Thanks Eric, I think the tranny rebuild will be this winters project. I only have a small 1 bay garage and the Indian Roadmaster resides in there during the riding season. I won't need to run it very often this summer. I'm thinking I will take a double split shaft collar and make some sort of soft rubber washer and slide the washer up against the bad seal and hold it there with the shaft collar. I hope it will slow the leak enough for now. Kinda bubble gum I know but it will bide me some time until I can tackle the rebuild. 3 Share this post Link to post Share on other sites
