Weldmart remanufactured;"Not "Rebuild" (There is huge difference) The Continental F-163 engine,
Here at Weldmart, we don't rebuild engines; technically, to be rebuilt, worn parts must be replaced. You take your engine to Joe Bob's Garage and just replace the worn piston rings, without reboring the block-it 's rebuilt. And you are screwed, but I had it rebuilt at an authorized repair station. Lincoln Electric has no technical ties to the engine manufacturer. Who did what to your engine?
The F series Continental engine goes back to the late 1920's, yes, it is mature technology. They were designed to produce high torque at lower RPM. They were never designed to run on detergent oil or ethanol-based fuel. When we remanufacture them, we have boring equipment that can guarantee 0.0001 tolerance from top to bottom of the cylinder. The new rings fit tight, TDC to DBC. The valve guides are replaced with hardened valve guides. ​
1.Engine block is totally disassembled for a preliminary inspection for obvious defects.
2.The block and head and other parts are cleaned in a gas furnace, at 700’ F, all the dirt and oil is
burnt off.The internal rust in the water passages is burnt and looks like sand, which is removed
with high pressure air. These parts return to their original gray cast iron color.
3.The block and head are inspected for defects, and repaired or rejected.
4.The head and he block are milled to assure flatness, very important to assure proper head gasket sealing.
5.The block is bored to size or has steel sleeves installed if necessary.
6.All internal parts are cleaned and inspected for defects, problem parts are replaced.
7.The crankshaft is turned down to accept undersized main bearing inserts. In some cases the crankshaft is so worn that it is buildup by welding and then turned down to standard size and balanced if necessary (it only turns at 1500 RPM’s).
8.The valve train parts are disassembled, inspected, defective parts are replaced (the original parts are simple and so robust that very few defective parts are found, the whole engine turns relatively slow and this slows meta to metal wear.
9.The valve seats and valves are reground and replaced if necessary with harden valve seats.
10.The valve springs are checked for height degradation, and are replaced as necessary.
11.The valve train is re assembled and checked for leaks.
12.The camshaft is inspected for defects and replaced if necessary; it is reinstalled with new camshaft bearings.
13.The original oil pump is removed cleaned and inspected for damaged and reinstalled.
14.The crankshaft, rods, and pistons are reinstalled.
15.The head is reinstalled, and checked for proper compression.
16.The oil pan, block heater, and front gear cover (with front seal installed) are reinstalled.

How to make your Continential engine last?
The advantages of the Continential F-163
Nobody ever thinks about the advantages of the Continential F-163. Why this engine in the Lincoln welder? The engine design goes back to 1929. The technology is what we call a "long stroke (the diameter of the bore is less than the stroke". This means you get lots of torque at lower (1500RPM).
​
Lincoln, back in 1939, designed the DC welder around an engine that runs at 1500 RPMs? Lower speeds means the everything that spins, spins slower and last longer.
The number one reason Continental F163 fails prematurely is in the SA200, not in the Miller Big 40 welders. The same engine (running at 1800 RPMs) will produce 400 amps. There is no seal-failure epidemic (same seal) in the Miller machine. Miller always used a large paper element air filter.
​​
1. Clean Air
The easiest, fastest upgrade to your SA200 is the best airfilter system money can buy. I still have welders who swear the oil bath is the best air filter ever made; you can't fix stupid. I don't debate, I ask 2 questions: #1, What weight oil do you put into the cup? #2 What new engine manufactured today has only an oil bath air filter?
​
Our remanded engines all come with our advanced air filter system and our PCV system.
2. Extra oil capacity without major modifications.
The next deficiency of the engine is that it does not have a full-flow oil filtration like your car. In the full flow system, every drop of oil that comes out of the oil pan is filtered before it lubricates the engine internals. This is why we have detergent motor oils. These engines were designed before detergent oils were available.
Replace your oil bath air filter.
