What Tecumseh Do I Have?

Recommended Posts

Your Shirtless Neighbor

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

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

It's an XL... Full cast-iron block and sleeve.

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!

      A HUGE thank you to Tony @Docwheelhorse for settin' me up here.
       
      The generosity of some of our members never ceases to amaze me.
       
      This here is another 1974 C160, but with the rare Tecumseh HH/OH160 OHV engine. Made one year only.
       
      It's rough. Very much in need of a full disassembly and restoration.
       
      When it came here it was missing one tie rod and the other was broken off one end.
      Today I popped used tie rods on and Trina used her 867 to drag it from the drive to the shed.
       
      The engine wouldn't move.
      Tin was near chock full of skeletal mouseseses and their house.
      Cleaned that out and the engine spins freely now.
       
      So progress has been made.
       
      It'll be a good long while before we get to this one but I just couldn't turn it down considering the rarity.

      We're going to take apart the Tecumseh from my Honey's 657 so I can replace the crankshaft.
      Any little tricks or tips I need to know about?

      So I have been working on a 656 I picked up at the end of last year and I did my first ever motor rebuild by my self on it. However it seems that I have lots of play in the piston and some slop at TDC more then I should have. So to finish the year mowing I am thinking of doing a predator swap while I go over the engine again. I am sure several people have done this before and I have a spare mounting plat to make it work. I am wondering if anyone has any pictures of ones they have done for help along the way. I know I will need a adapter to use the factory pulley and I don't want to destroy any of the sheetmetal since it is in good shape. I will keep you posted as I go along and eventually when I get the hh60 back together correctly to re install.

      I know where the balloon sticker goes and the oil sticker.
       
      Where does the large "Solid State" one belong??
