Just picked up a troy built tiller with this engine. Thanks for going thru all the details on the engine. I'm not sure I'll do all that work you did but it's good to know if I have to . Regards, Tom, Ontario, Canada

Really glad to find this video. I have two old (mid '70's) TroyBilt Horse tillers with the same Techumsa engines. One is dead, the other is extremely tired. I'd like to use this video to try to rebuild one good engine out of the two. I think it would be a great way to learn how to rebuild engines. Also glad that you have a normal speed version of this rebuild. I was disappointed initially that you fast-forwarded through the most important part. Thanks!

Dude I have to say, that was a great video. It was real, and you didn't hide your mistakes so we can learn along with you. I say keep finding old engines and bring them back to life! Thanks for sharing.

Good thing you have got patient To work on that motor all over and over again That was good the effort ; you got running.

dude that's awesome. Thanks a lot man. I just got myself a atco mower with this engine. its a big restore challenge as the mower is very old. wish me luck.

Nice to see the old unit working again.

Great video! Liked watching you go through the different problems and got it to work!

You did a real good job with that motor ,that is awsome

I have one of these old Troy Bilt tillers with a Tecumseh 6hp engine that wouldn't start - I replaced it with a Harbor Freight 212 Predator and it was fairly simple direct fit and the Predator is working just fine. I will try to rebuild the Tecumseh someday but not just ready to do it at this time.

very good video. my 1986 troy-bilt tiller has the same engine and was running fine a couple days ago and i shut it down to tighten the drive belt. since then it has decided not to start. after checking things out i saw the compression was really low. (60 psi) so i decided it needed rings. well after thinking about it i decided i better check valve clearances first before tearing into the engine to replace the rings. i have yet to do that but i had an old 3 horse tiller with a similar problem a few years ago and it turned out to be tight valves. i have yet to check them but i am hoping that is the issue because it is so much easier fixing that than installing piston rings. you stated it did not look like there was a way to adjust the valve clearance. well you have to remove the valve and grind a bit off the stem to get the necessary clearance. i found that out with that small tiller i fixed. i made a special tool to remove the valve springs and still have it. i am just hoping that is my problem.

I understand why you called it a turd but these were nice engines. Mine served many hard years on a troy bilt tiller.

Nice job, you are a patient and knowledgeable man. I hope you chugged a beer or two after you got her purring.

I want to just run my rototiller and get the garden in, not spend a week rebuilding the old engine on it every time I need to use it. Waiting for obsolete parts from antique parts suppliers. I'm willing to pay $100 every 5 years to just have a tiller that is there, reliable and strong and ready to go when I need it.

With the amount of carbon build up in that engine, I'd say it's far more likely that the damage to the top of the piston and combustion chamber was due to chunks of that carbon coming loose. I've completely rebuilt one of these HH60's and have another that I need to finish the rebuild on(oddly enough, this one had a governor failure and piston skirt damage too...ran like a top anyway). A couple of hours ago, I finished replacing a HH60 with a $120 212cc Predator motor. I would have shimmed the crank on that to get the endplay into tolerance....should have been a shim in there already IIRC. Also, I didn't see you check end gap on the rings before installing them on the piston. Always check that because they might be file to fit instead of drop in. I like old engines, but the Predator starts way better than any tecumseh I've ever had the displeasure of using, makes far less noise, has electronic ignition, and is more fuel efficient. Tecumseh has been out of business for a while now, and parts are getting harder to find. Just not much point fighting the tecumseh back into prime condition(which isn't all that much to write home about IMO) instead of replacing it.

I watched your video but it really moves too fast for me to catch all the little nuances of tear down , rebuild and reassembly.

But right now even though I’ve removed the bolt from the flywheel it won’t come off. Im stuck here. Thanks. Nick

That's a lot of endplay on that crank, but it might run OK like that. When it exceeds the side play on the rod's crankpin, that's where it can get ugly. A little "backyard machining" of the face on that end cover using emory cloth on a piece of glass might help.

Ebay, just search HH60 rebuild.

Almost sure that is a 6 hp from a Troy-Bilt Horse model rototiller. Looks exactly like mine including the fuel tank except the air cleaner is a little different. Don''t even know how old mine is, probably 1950s or 1960s, still runs great, has never needed any service on the actual engine other than replacing the flywheel key, and it's seen plenty of use.

Can you please show me a picture of the car raider I’m looking for one I can’t find one

So many of those old parts are hard or impossible to get anymore. And breaker points, mounted underneath the flywheel? where it is a real hassle for you to have to get in there periodically and service them....Not to mention that flat head engine designs makes less power and torque than modern designs. All those old engines were kind of made to be disposable. I started getting into the old Troy Bilt Horse models, ended up with 4 of them, and every one of them had a lack of power problem (the original tired engines were too wimpy too pull the big Horse Tillers without bogging down when I'd run the tines down deep, no matter how much I tinkered with them). There was several 7hp tecumseh and (1) 8hp cast iron kohler industrial. I'd rebuild the carbs and service the breaker points. I used to work many years ago as a pro small engine mechanic, and on those very same engines... They were ALL too tired from low compression to pull strong enough on those big old Horse Models tillers. Instead of trying to bore and re-ring them and grind valves and seats I simply replaced the old units with Harbor Freight Predator Engines (212cc horizontal shaft engines that have the shaft and mounting bolt patterns identical to the original old engines!!). These "Honda Clone" (Chinese copies of Honda engines that have parts interchangeable with Honda' engines) can be bought new for $99.-$119. from Harbor Freight. I have found them to be really powerful, good running, and durable engines that pull my Troy Bilt Horse Tillers strongly without bogging down!! Be sure to fit new (industrial grade v-belt drive belts from NAPA auto parts) when re-powering, as these Predators have enough juice to just shred the old marginal belts.

Look like a engine off of a Troy bolt pony tiller I believe they did a Kholer powered version. And a Tecumseh version. I don’t think the exhaust is correct for it’s vintage but hey it works

Hmm... backfire suggests the timing could be off, slightly too far advanced. Grey smoke is oil, but that will happen on any engine after a rebuild for the first 30-40 seconds. You could be a little rich on the carb too. My suggestion is to start clean. Pop the flywheel off, check the points are at .020 gap at the little mark on the ignition cam (the one under the timing plate). The small black plastic part of the points that rides on the cam should be between the two small hash marks on the cam.... then set the points at exactly .020". I would also suggest making sure they're clean by using a piece of 1000 grit paper on the points. After that, be sure the bottom (fuel) screw on the carb is only out 1.5 turns from bottomed out (don't bottom it out hard or you risk breaking it), and the air screw (on the side) is out only 1 turn from bottomed out (again be careful not to snap the tip off bottoming it out). Then give it another go. You could check the valves too, make sure the engine is at TDC, then check that the gap is .012-.015 on the exhaust and .008-.010 on the intake. Any more than that and you'll have to replace the tappets, possibly the valves. Nathaniel Gibbs

The HH60 was probably Tecumseh's best engine. Mine is original on my '73 Troy Bilt and it runs like new. 75-80 psi on a compression test.

I would never run non-detergent SAE 30 in an engine. Run HD 30 which contains all the required detergent additives to keep engine internals clean. Additionally, the HD 30 very likely is a parafinnic base oil which is superior in engine use vs napthenic base oils commonly found in ND 30 products.

@AimlessMoto

7 жыл бұрын

Considering the motor is freshly honed and has new rings, piston, and other internals, and everything was 100% clean when re-assembled, running non-detergent, high zinc, dino-oil is a really good way to break in the engine. It allows for seating of the rings, and ensures good wear-in for the bushings. After I put about 5-10 hours on this motor, I will definitely run a more modern oil. I probably will not go with Synthetic, but something with much less zinc.

What else let me know? I may not have the bracket linkage because I sold the carb a while back, but I have the bracket and everything else for the governor. Let me know if I forgot something. If you want those parts I'll throw them on ebay and send you the item number, so you can find it right away. Let me know if you need any more parts. I still have a lot of parts left from a couple 71" H70 engines I parted out. Most of the parts for that engine sold and pretty fast so a lot of people are keeping those older Horizontal Tecumseh engines going, they are popular engines.

I just ensure it won't over-rev or reach valve-float by bending the tab on the back of the throttle plate to touch the carburetor... this way it's impossible to over-rev it, but I still have a linkage for a throttle cable... and no governor to blow-up again. cnrmoose

The engine has so much blow by it it makes the oil so dirty that it needs two oil changes a year for only 8 hours a year of runtime a year.
