Exclamation Re: Novo Gas Engine 1918 40HP Model EF 4&3/4x6 4 Cylinder

Nice looking engine! One thing though - I would test your gas tank repair. The last time I used JB Weld on a fuel tank, E-10 gas stripped it off faster than you could say SNOT! The gas took it off like paint remover removing a cheap paint. Check it out before you begin re-assembly You might try and seal the JB from the gas with the alcohol resistant tank sealer Lee Pederson sells It will definitely seal the tank. Lee is a sponsor here on the Stak. Keep us posted with your progress!

The fuel tank is rinsed out with 6 cans of break cleaner. I am waiting for a gallon of Pedersen's gas tank sealer i ordered before any further assembly of the engine. the governor is now rebuilt and ready to install.

What a cool project! That's a big engine!
It finally dawned on me how big it is when I looked at the title of your thread again. My largest Twin City tractor engine (so far) is 4-5/8 x 6. Close but no cigar!
Cooler still is that your Novo is a stationary engine... I've never seen one before and if I liked to drive, I'd drive to Michigan just to see that brute!
Thank you for sharing this.
Nice Regular by the way.

Sealed the gas tank today with 1 gallon of Petersen's gas tank sealer. The tank looks good inside. I was limited in how much i could slosh it around considering she engine weight partially assembled is likely over 900 lbs. I picked the engine up with the chain fall with the chains positioned to allow the engine to flip upside down to spread the sealer around in the cast iron fuel tank which is the engine base, but it was so hard to flip back up that i resorted to blowing the sealer around inside the tank with an unrestricted air gun with a tube extension. after some of that I drained out the sealer and let the first coat cure awhile, then i poured the sealer back in and blew it around with the air gun some more. after more sloshing from side to side I drained out about a cup of sealant that was just about sludge. then I allowed what wanted to come out to drain and ran an low Wattage heat gun bowing inside the tank for several more hours. it was an all day process as the instructions on the can advise.
Between sealant stages I Freed and repaired the end-play limiters on the timing gear cover designed to limit end play of the Crankshaft and camshaft. cut several gaskets cleaned with a wire brush in the bench grinder a endless number of bolts and the pushed each one into a hole punched in a cardboard box to allow priming the heads. Then installed the Governor assembly, timing gear cover, and the end-cover below the oil pump. The crankshaft seals are felt, easy to make of felt worms bought on ebay a few weeks back. My one day off from work weekly ran out too soon again, and I took the photos after dark.

I repaired the serial plate and separated parts for the sandblaster. The serial plate is attached using No. 8 drive screws. I ordered about a 100 NOS NO.8 drive screws in an old tattered box I found on ebay for about $4.00 but found the standard drive screws have a smaller head than the ones used in 1918 so I ordered a package of 15 from "Blacksmith Bolt Co." to see if theirs have larger heads before installing the repaired serial plate on the governor housing. The water pump was one of the last components I finally dismantled. All of the parts have to be removed from the shaft accept the impeller before pulling the housings from the pump shaft. I boiled the paper drive coupling that fits between the governor drive and water pump in linseed oil for a couple of hours then clamped with a bolt and large washers to allow the linseed oil to set up while under pressure to keep it flat. I pulled the (Governor coupling+fuel pump eccentric+magneto drive coupling from the water pump shaft after drilling out the retainer pins, which appear to be taper pins, and then removed one side of the water pump housing and drove the shaft with the brass impeller from the second half of the water pump housing. All water pump parts are shown in the photo accept for the fuel pump eccentric which is bolted to a threaded rod with other small parts to make it easier for the sandblaster. After cleaning all the water pump parts accept the housings which are going to the sandblaster, I watched the boys mount rear steel on the regular attaching the lugs with square headed bolts from "Blacksmith bolt Co."

While many parts are waiting at the sandblaster for his attention I looked for somewhere I could make progress... I Lifted the engine and cleaned and undercoated the bottom with an asphalt base undercoat to prevent further deterioration from ground moisture. I cut the corners from the skid-rails to match the creosoted wood beams. I mounted the repaired serial plate using the #8 drive screws from "Blacksmith Bolt" and applied a sealer behind the plate to assure no movement would occur later with vibration. You can also see a double lifter support That was broken into four or five pieces that I repaired to reduce machine shop cost that would be needed to reproduce the part.

m, what kind of goop did you spray on the underside? I like that notion!
