I spent the past couple of days working on the engine so that I can get the tractor back together. This engine was in great shape, but the exhaust valve was sloppy in the guide, so I had a valve guide bushing installed. The old rawhide crankshaft seals were leaking, and the oil ring was worn out of spec. A car coil was being used for spark, but I converted the engine back to the original 3 leg armature. I replaced the piston, rings, gaskets, seals, valves, and muffler. The head was slightly warped, so I flattened it out with sandpaper and a piece of thick flat steel. The throttle shaft is still tight on the original carb, and the carb functioned fine. I just have to torque the head bolts down and hook up the governor and carb linkage. Other than that, it's just about ready to install.
I would have finished it today, but I had some other things to do. It's pretty cheap to freshen up these old Briggs engines, and it beats the heck out of smelling burning oil and dealing with oil leaks. Here are a few pics I took along the way.

The head is the last thing I do. Just in case I have to go back in. Good Luck, Rick

I plan on starting the engine tomorrow. I'm glad that the sun is shining and the temps are warming up.I'm still working on cleaning up the rest of the tractor, but I'm almost done. I have to clean the front axle and install the spindle bushings, but that will go quick. I'm not painting anything, just cleaning and fixing any issues. Here are some pics just before I got distracted with some other tractors.

Jim,

 

If I bought over my Squire 9 this summer would you be willing to freshen up The 23D ? I do not have a garage for rainy days. My days are already filled, sunday to sunday for the most part. I have been watching you since you joined and you really enjoy this and is very good at it.

 

Right now I am frantically working on the grinder and is working with my parts man in England, so late in the season already,....

I would rebuild your engine for you, Trowel. The thing is, there's just no telling what your engine will need. If the bore is tapered, out of round,or oversize out of spec, I have no means of boring it. Also, if the crank pin is worn beyond spec and the crank needs to be turned down, a new rod will be difficult to find. I have some blocks and cranks that will sit because they are beyond reject specs for a std. rebuild. I had to use two 23d engines to make one for my 64 Landlord. Since you work your machine a lot, you will want everything tight as a drum when it goes back together so it will last.

Thanks. When I replaced the head gasket I took specs and notes of what I need, I can go thought that with you without highjacking your thread any further.

 

I have three choices, rebuild the engine or rebuild a 24000 series to replace it or sell it to you with all the attachments and manuals.

You should keep it Jessee. Don't worry about hijacking the thread, it all relates to what we are doing. I just pulled the engine off of the 62 squire and bolted the B1 engine in place for a test run. The B1 still needs more cleaning and assembly, so it made sense to just swap engines in The Squire. The B1 engine fired right up and I took the Squire for a ride. No smoke, no valve ticking, and plenty of power in 3rd when climbing hills. A fresh rebuild will make you wonder why you didn't do it sooner. Here's a short video of the engine running. I will be adding a second governor spring like the model 23 engines have. I did this to the Squire model 19, and it makes the governor action a bit smoother.

I ended up with the flu last week, so I had to stop working on the tractor. Man, I haven't been sick like that in years and it wiped me out completely. I felt better yesterday, so I started assembling the chassis and ran the wiring. I made a new bushing for the front axle pivot bolt and installed new spindle bushings. I installed the engine, gas tank, and battery and started up the tractor. I took the tractor for a short ride and everything is good to go! I still have to finish cleaning the hood and grill assemblies, and install the points cover. I'm going to install the front weight, wheel weights, and the 10" plow, so I can plow the garden at the end of the week. Tomorrow, I'll change the engine oil and I'll change the oil again after plowing.
