So, this is the muffler on Bror…  And I THINK I’m going to need to pull it off, just to be able to tear down the rest of the engine…  I dunno, maybe I can leave it on when I go to pull the engine, because I THINK that piece of frame that is riding right underneath the muffler will come off when I lift the engine out…  I hope so, because I can’t seem to get the pipe out of the exhaust port… Any suggestions would be welcome…  Here’s how its mounted…

So, I took the day off today to play tractors, since the weather really didn’t cooperate yesterday and I had other things to do…  Figured I’d work a bit more on clearing things off of Bror so that I could have better access to hit the engine with a pressure washer sometime soon…

Pulled the fuel tank…  Think I might need to clean the sediment bowl…

Hmm... gas looks a bit cloudy!

Moved from taking the gas can off to trying to get the choke and throttle cables off… The big issue there is always the knobs… You can’t get the controls out with the knobs on, and I couldn’t figure out how to get the knobs OFF… Fortunately, they’re just pull-offs… but really hard pull-offs… Not like the wimpy ones you get THESE DAYS…

Look at how far that lever goes INTO the knob!

The throttle cable still has SOME motion, the choke cable is completely seized… I’ve thrown some WD40 into the ends of it, we’ll see… Interesting thing about these cables, they are the wire coil ones, I thought they were fastened into the control levers somehow… Turns out they thread into each of them… Cool!

Moved onto pulling the dashboard off so I’d have better access to the electrical within the pedestal… Here’s the ignition switch in the pedestal

Can YOU see it?

Bit hard to see, under the dashboard… All the more reason to remove the dashboard…  And the battery tray.

Here’s the dashboard removed, but the battery tray still there…

Diggin' in deeper!

Of course, what I DIDN’T realize is that the voltage regulator and solenoid are attached to the bottom of the battery tray:

Once I had the battery tray out, I could see right into the pedestal… And it wasn’t a pretty sight….

Gucky!

So, I fired up the air compressor, and got out the blow gun!

Cleaner!

Quite a difference!  I actually went after the whole engine compartment now that I had it opened up a bit….  Got the front cleaner..  Here’s a comparison….

So, I feel a LOT better having gotten so much crud out… And in looking at the electrical I found that the solenoid still works (yay!) and the mechanical voltage regulator looks amazing!

Here’s the outside:

Voltage Regulator outside

Here’s the inside:

Voltage regulator, inside...

Looks like it just came from the factory!  Amazing, considering its over 40 years old… Dunno how to TEST it, but I hope it works as good as it looks!

So, I took the front posts off, and found THIS between where the front posts had been and the mount points:

Buckets o' Grease!

I am really finding that the mounds of grease HAVE done a fairly good job of preserving spots on this tractor!

So, I’ve got ONE more piece of metal to remove (I think) before I can pull the engine… Just can’t figure out how to get it out… I’ve missed a bolt I’m sure, AND this piece butts up against the muffler… Hope someone can tell me how to get the muffler off!So, all in all, a good day of wrenching… Slow but steady wins the race…

Getting Bror up and going….

• Wiring harness
• Positive and negative battery cables
• PTO Safety Switch
• Gasket kit for engine
• New float for gas gauge
• Variator handle
• Choke cable
• Throttle cable

Went out to drop the head back onto Bror’s cylinder, but (of course) I got a bit carried away….  Couldn’t leave it how it WAS when I pulled it off last week….

Bror's valves and piston as I found them

Here’s what an hour of elbow grease and some degreaser did…..

After some scrubbing

You can even see the machining on the piston face!  LOTS of carbon built up….  The valves cleaned up nice too but I think the intake valve needs replacement….  Also, I have some concerns about the valve seats… Like are they even there?

So, when I pulled the cylinder head off of Bror, here is what I found….

Bror's valves and piston face

Here’s what the carb looks like:

Bror's Carb, before

Bror's Walbro carb, the choke plate

Bror's throttle butterfly valve

So, that’s kinda disappointing to see.   The Walbro carbs for the JD 112/Tecumseh HH110 engine are kinda hard to find (read: impossible) so that would be a bit of a show stopper… However, while cruising MTF, I saw a post from a guy who runs CarbRescue.com. So, on a whim, I PM’ed him to see what he thought… Here’s his response:

“Bring it on son. That’s pretty nasty. If the body isn’t rotted out, particularly under the bowl, it’s a walk in the park. By the way, I don’t just clean. I do full restorations and make any part on it that I need to. On top of that, I guarantee my work and that it will run like a new carburetor when I’m done. You just make sure you save those pictures for some before and after posting on here. Hehe. Be glad to do it for you if you decide the motor is good. ”

Soooo… Once I’ve had a chance to really tear into the motor and figure out whether its worth proceeding, I think I will send him my carb….
