Home Forums Hunting & Shooting Hunter's Campfire A friend has an old Troy-Bilt 7 hp tiller

that the engine is kaput. Are there any of the original Troy-Bilt engines available anywhere? I'm probably going to wind up with the tiller and would like to get it running again.

Can't use a Briggs or Honda?

I had a machinist friend that did that with a TB. It wasn't pretty but it ran and was a hell of a lot cheaper than the $700 he was quoted for a replacement from TB. The take away was to check the oil EVERY time you run it. LOL

I have an old Merry tiller and I dropped a Briggs on it. It runs great. I like Briggs and Stratton engines cause they seem to last for ever, but those Hondas sure run quiet.

I have a 7 HP with a Kohler on it.
Here is a link for TB parts. Hope this helps.

I don't think TB ever built their own engine. There should be a bolt on replacement available, perhaps from more than one maker even.
Seems they usually have a Briggs or Kohler in the old models, Hondas on some of the later models.

Is it really an engine problem, or just a plugged-up carburetor? Modern gas is 10% alcohol and 10% recycled chewing gum.

here's a good place to start

now for the blasphemy - some have had good luck with the import Honda clone that Harbor Freight sells

good luck

find a website that give the specs on motors: mounting base hole pattern, shaft length & diameter, left or right side drive, etc. Then match up what they have to what you need.

Mickey,
What exactly is wrong with the motor? You can still get rebuild kits for most motors, and it might be a good way to go.

Another option is a Chang Fa Chinese clone of a diesel Yanmar. You can pick up those for around $500 in the crate, and it should bolt right up. Better gph and longevity over gas, and is worth considering.

Have you got a link to the Chang Fa dealer / supplier ??

You can replace it with any horizontal shaft motor.As far as mounting holes go you can make your own if they do not line up.Troy does not manufacture their own engine.It could be Tecumsah,Briggs,Kohler or who ever they got the best price from.

The "7Hp" was either a Kohler (GOOD) or a Tecumseh (BAD, very bad)

......Tecumseh is out of business, and parts rare to non existent.

The Kohlers are solid old Iron,....parts CAN be had, and they are well worth the rebuild.

Troy's big design failure was using float bowl carbs, and updating to a diaphragm type is cool beans, I know of a source for 'Racing" carbs that still hane adjustable main jets.

The "Flange Bolt Circle" is (I believe) 4 7/8" (2 9/16 Square Pattern) , and the shaft a 3/4"

Modifying the Trotbilt Pulley to accept the more common 1" and 25 MM (Honda) is a snap for one with a lathe or mill.

While you're that far into the the Machine check and adjust the end play on the Worm drive Bearings,....if those are kept in skew those drivelines will outlast all of us,.....

I'm kinda' looking at phasing out my Tecumseh,.....endless carb problems with this damned ethanol being one of the main reasons.

I've got a small (but growing) Troy Horse Boneyard , if anyone is in a world of hurt for an un-available part.

"As far as mounting holes go you can make your own if they do not line up."

UH, excuse me ....?

GTC

I've got two Troy-Bilts with Tecumseh engines and carb problems.

Anyone converted to propane as a solution?

Bruce

I was sure dead wrong on the "Bolt Circle",....although that 2 9/16" "square" pattern just may work out to it.....?

That 11 HP Briggs looks like a good upgrade for the casual user.

Damn they are PROUD of those Kohlers, Eh?

Thanks for the link !

Here you go Cross,

This one should bolt right on. Supposedly you can till 20 acres in about 5 minutes.

Went back and edited all the dumb dimensional call outs.

This is another HOT source, and I thank you, and a couple of fine old Tillers probably will, too......
