possible to replace the gas engine on old welder?
Grant Erwin
squint at it and ignore the gas engine, which is missing a lot of parts. I may
get lucky and find a parts source, but right now I'm wondering if it might be
possible to just go find another motor with similar specs and just patch it in.
Anyone done this?

likely to fit would be another motor from the same model machine. The engine
crankshaft is likely to have a taper fitting for the rotor. Don't overlook
the need for a suitable governor.
Of course, all of that would be a plus factor for a machinist looking for a
project. (BG)

ones. Have you determined exactly what kind of engine it is (was)?

generator. Usually means that the main beaing on the engine is shared
with the generator. The generator uses a tapered fitting to be perfectly
centered on the crankshaft. The taper can be most anything, probably not
standardized beyond the engine manufacturer. Net: either the taper or
the bearing will get in the way of reuse.
If the engine is toast, I'd machine a new plate with a suitable bearing
for the generator section, use a belt drive for power.

Pretty sure it's Briggs & Stratton so far, don't know which exact one yet.

from the original engine and reuse in order to get the correct taper.

Call these guys and ask if they can recommend a substitute

Make sure the generator is OK before putting a lot of effort into the motor.
Note what others have said about the usefulness of a non DC welder and
especially one with limited duty cycle. IMHO this is/was a pretty marginal
unit even when it was new. it is basically a small AC only buzz box with
the added disadvantage of needing expensive gasoline and maintenance.
IMHO, Good tradesmen don't waste time on or with poor tools, they just make
it harder to do a good job, and are much less pleasurable to use.
Good luck, YMMV

It may have been a marginal unit, but it is certainly an AC/DC welder. Lincoln
did make AC only models, perhaps you are remembering one of those. There are
some OK pics of a very very similar welder in much better shape than mine on a
current ebay auction (150140941115), here are pics of the gas engine on it:

South Seattle Community College has one of these welders, and Ernie says it has
exceptionally smooth DC.
If I can get it running correctly and completely functional for under about $400
total, then I'm going to do it. If not, then I'm going to part it out and keep
the leads. If it doesn't weld well then I will certainly let it go. I've been
pricing gas-powered welders for awhile, seems like $800 and up is the going rate
around my neck of the woods for clean functional units.

I stand corrected. I was relying on the specs (AC only 25% duty cycle)
quoted by a poster in the previous thread, and my preference for DC stick
welders is showing. I have not owned one of these and cannot remember what
they weld like. I would rely on Ernie's judgment. I suspect that the duty
cycle is much higher when using 1/8" or 3/32" rods which I suspect will be
most of your usage but be careful when using 5/32". IIRC there is a formula
for calculating reduced current duty cycle but I do not have it or a URL
handy, try Google or perhaps someone here can help.
The earlier poster also mentioned an Onan engine which IMHE do have pricey
parts. I cannot think of a more common small engine than the Briggs and
suspect that it will be much easier to fix economically. I do suggest a
careful inspection of the welder first and would try to Google a spec sheet
(and users manual) just so you will know what you have and what to expect.
IMHO Lincoln electrics are usually above average in quality and performance.
Good luck

Well, you've got a Briggs & Straton engine. Parts should be available
for it. From the picture the air cleaner is still on it which probably
means that the carb is still there and it probably needs cleaning and
maybe a new float valve.
The exhaust is a piece of water pipe and will be noisy but you can
always weld a muffler on that.
Unless there is something else missing that doesn't show in the
picture I'd say you could get it running in a day or so.
Take the spark plug out and short the threads to the head and give the
rope a pull. If you see a spark that part is working. If you have
spark squirt a little gas in the plug hole, screw the plug back in and
give her a pull. I'll bet she'll pop and it does that it'll run with a
little more fooling with it.
I'd try to find a guy that repairs lawn mowers and have a chat with
him. Most of these guys know something about B&S engines. If you can
find one that is semi-retired and bring over a six pack I'll bet you
can get it fixed.
Once you get the engine running check, and maybe replace the brushes
in the generator, and if necessary bake the windings and repaint them
and I'd reckon you'll have a pretty good little welder.
Lastly, if you are having trouble finding parts ping "Gunner" either
here or on rec. metalworking. Apparently he has most of the parts in
California stored in Bakersfield and knows where all the rest of the
parts in California are hidden.

You have mistaken my post's meaning. The pictures I posted are from an ebay
auction, *not* pictures of my machine. My motor is a POS compared to the one

I finally realized that about the time I pushed the send button =:-(
If your machine is the same as shown on
http://www.hobartwelders.com/mboard/showthread.php?p=212488
it is a pretty good welder. Probably worth fixing. The one cylinder
engine is probably fixable, Certainly with the prices I see mentioned
worth repairing if it isn't totally trashed.
A couple of things. If you get the engine running then have a look at
the generator. Make sure that the brushes are nearly new and the
commutator/slip rings are clean and smooth. By the way, brushes are
pretty generic, you don;t have to order from Lincoln, probably any
motor rebuild shop will have replacements. If it were mine I'd either
pay to have the thing baked and re-varnished or do it myself as if the
windings have absorbed any moisture over the years the arc probably
won't be very stable.

Based on the .pdf, that looks like a substantial machine, I think I'd
try to bring it back.

I got word from Lincoln today with the exact model & type number of the Briggs &
Stratton engine. With that, I was able to download the manual & exploded parts
list from the B&S site. Now theoretically I can start compiling a list of parts
I need and pricing them out. I called Briggs and they told me I can't simply
order a replacement engine, so either I'll have to find one from a broken welder
or I'll have to rebuild this one.
Grant

identical except for the crankshaft. If you call the B&S folk back, you
might be able to worm it out of them what to look for. Then you have to
pull cranks and swap the old crank into the new engine. If they use ball
bearings like the equivilent Kohler, the cranks tend to be ok.
And I'd agree that this unit is much heavier duty than the Weldanpower 225
