What Tecumseh Do I Have?

[Your Shirtless Neighbor 2]

Hi Gents,

 

I just joined up because I started digging into a Tecumseh I've had laying around for about 4 years.

 

Unfortunately, the piston is cracked, and the governor had exploded... all other parts are in great shape, but I want to know what I have before I start buying parts to repair it.

 

The motor is an XL Xtra Life, with a Kleen Air can on it (filter is missing of course). It's a top-tank, metal, with the filler on the side (not the center), all of the electronics are internal of the flywheel.

 

I'm guessing it's an HH60, but I feel that it's "bigger" than a 6hp.

 

Here are some photos. I can brake out the verniers and take some measurements... what should I measure to determine the engine size? Bore x Stroke?

 

 

Engine 1

Engine 2

What format are your pictures in???

 

h/hh60 bore 2.625  stroke 2-1/2

hh70  2.75     2-17/32

 

hh100 Bore 3.3126 stroke 2.75

Paul, I could open the pictures in "Paint".

Aluminum Block H series could be a H50/60 0r 70...Most likely 60

Pics are in Jpeg.

 

I think it might be an HH70.... I did throw verniers on the bore when I tore it down and I am pretty sure it was 2.77... I'll double check tonight.

Ok, will check that. Pictures are in .jpeg.

 

 

  Saw the pics after Steves post.  My bad block didn't look rusty enough to be cast iron

 

The XL designation is usually on the blower shroud  so should the engine series number be stamped on there

Yea, the top got a REALLY good cleaning... there was about 1/4 inch of carbon around the exhaust port... so either the governor broke, broke the piston, and it got blow-by, or someone was running 2 stroke gas in it.

 

The rings and oil seals on the piston are perfect, only damage to the piston is the missing chunk, and the cylinder and valves are like new now that they've been soaked in carb cleaner and beat to death with a wire wheel.

Is there no ID stamped on the blower housing??

It's an HH60! There was dirt covering the stamping on the blower cover... sheesh. And I checked the bore and stroke... 2.60 bore X 2.52 stroke. 

 

Now I can order parts! Thanks guys!
