1924 Jaeger 2 HP Engine
I had my 1935 Briggs Model Y listed for sale for $200. My buddy Homer, who is also an engine collector, had picked up this old gal at a scrap yard where he was doing some field service work. I offered him the Model Y for a trade and he accepted, with the condition, he'd get first chance at it should I decide to sell it after it's restored. This will not be a quick restoration! She's 82 years old, and it shows. A lot of wear, some broken and some missing parts. Biggest issues is the magneto is missing. The valve rockers and rocker supports are missing. The head is broken where the rocker supports should be. The igniter plate is also broken. If that's not enough, it will not turn over. Something is binding.
------------------------------------------------------------------------------------------------
A little tinkering found the binding issue. The pin for the fly ball governor is shot!
The worn out pin was letting the governor gear to wobble enough to bind with the other gears. We can fix that!
The original pin was .312" in diameter. I had some 3/8" steel in the stock box, and turned it down to size. Drilled 2 holes in the ends for 1/16 cotters, and were in business.
The engine will turn over now. There have been a lot of braze repairs to different parts. I've got a long way to go yet!
------------------------------------------------------------------------------------------------
Still looking to play with the new lathe, the next item tackled was this badly corroded carb needle.
An hour at the lathe and my first attempt ever at threading on a lathe produced this usable replacement.
------------------------------------------------------------------------------------------------
More disassembly proved the cylinder and piston are in great shape!
The bearings are all pretty much shot, but we can make those as well.
------------------------------------------------------------------------------------------------
Another item I'll need to make is a replacement fuel tank.
The original tank is rusted badly rusted out. It's a pretty simple sheet metal box with two fittings and a vent soldered into. I've never attempted to make a liquid tight box before, but there's always a first time.
------------------------------------------------------------------------------------------------
I had been putting this off. The cam gear shaft is retained with a square head set screw which was broken off flush with the frame. As with most feared issues, it was no big deal.
It was drilled, and came out easily with an easy-out extractor.
---------------------------------
After removing the broken screw the shaft came out. Not a good site. It was worn beyond repair. A little time at the lathe and drill press turned out a decent replacement.
I still don't have a milling machine, so the set screw flat was cut by hand with a file. It will work just fine.
------------------------------------------------------------------------------------------------
The oiler was broken off when I received this engine. I had pretty much given it up for dead.
Still, I decided to clean it up to see what was there. It ended up being a diamond in the rough.
I'll try tapping the pipe thread a little deeper in the oil tube to make it work.
------------------------------------------------------------------------------------------------
The water hopper was full of mud, rust, hickory nut shells and junk, including this part of a knife blade.
I'll bet that made someone talk to them self when that happened.
It took some time with a pressure nozzle to get it cleaned out, but it looks good.
------------------------------------------------------------------------------------------------
It's stripped down to the bare frame at this point. The babbit bearing liners for the crankshaft bearing are left undisturbed, other than that everything is off.
------------------------------------------------------------------------------------------------
The cam surface of the cam gear and cam roller look passable.
Yes that is a braze repair in the trip lever, but it was well done and looks like it should be Ok.
Much More To Come!
