Questions & Answers about repowering and repairing Case garden tractors:
Q: Can you tell me the spark plug gap for Ingersoll 446 and the points gap
for an Ingersoll 446?
A: The spark plugs
should be .030, the points .018.
Q: I noticed that on my friends newer Ingersoll tractor (he has
an 18 HP Onan) model that the Onan engine is reversed to my engine
(16 hp Onan) front to back. I cannot put in a new engine that will
have the rotation reversed by placing the engine backwards since the
rotation would be backwards to the rotation of my snow thrower.
Therefore I can only install the new
engine the same way my old engine .
That is not a problem for me. Will the Electric clutch that you sell
be effected? Inn other words do I have to get a CCW or CW clutch or
will the electric clutch work in either direction so that my
implements will work?
A: Yes, you
are correct about getting the correct PTO clutch that is built to go
in the direction in accordance to the way the engine is installed on
the tractor. Yes, an electric clutch will work in both directions
but in no time at all it will blow up when running in the backward
direction of the way it was built to run. I have that all figured
out and taken care of.
Q: My Case 446 has a plastic fan that is used to cool the
hydraulic oil and is driven by the mechanical PTO. If I get the
electric PTO how will the fan be driven. Will I have to install a
separate electric fan drive and if so will there be any clearance
problems?
A: I have
things all figured out for your plastic fan so your current fan will
bolt right onto my electric PTO clutch package.
Q: I have a Case 446 with an Onan engine. I have a couple of
questions if I go with the Vanguard engine and kit. The Onan has a
front shaft to drive the fan blade, but the Vanguard does not - how
will it work?
Will the Vanguard be able to pump fuel from the gas tank which is
located below the level of the engine and several feet away under
the driver's seat?
A: Yes, the
Vanguard engine has a front shaft
that is included with the installation kit. Yes our Vanguard has a
strong fuel pump that comes right with the engine.
Q: I have a 16 horsepower vertical shaft Vanguard engine. I’m
guessing that since the 18 HP Onan in the Case Ingersoll 448 tractor
now is a horizontal shaft, this particular Vanguard won’t work. Am I
right?
A: Yes, you are correct, you can not
install a vertical engine where a horizontal engine came out.
I have a 1988 Case 446 garden tractor - a few questions:
Q: Will the
Vanguard 23 horsepower engine fit
my Case 446?
A: Yes
Q: Will your kit bolt up to my pump? (With the 23 horsepower
Vanguard engine?) A: Yes
Q: Will your electric clutch conversion kit work with
the B&S 23hp in my Case 446?
A: Yes
Q: Does the Vanguard engine come with a fuel pump,
if so is it the pulse type like the Onan?
A: Yes
Q: When using your conversion kit is the C-I charging
regulator module retained or by-passed?
A: The regulator is already mounted and wired on the
engine.
Q: What is the warranty on the engine?
A: This engine has a 2 year
commercial warrantee
Q: Will it be affected by my doing the install?
A: You installing it has no effect on
the warrantee.
When you order you kit or kits you can call me
on my toll free number and if you have any questions or problems I
can talk you through them. We are open until 9 pm Central time.
Q: What is the cost of your electric PTO kit for the mower deck?
what engines will it work on? 14 HP Kohler engines?
A: My electric PTO kit will work on the
Vanguard 14, 16, 18, 20, 21, and 23 horsepower engines.
Q: I'm considering the purchase of a used
Case 444 tractor. Can it be repowered with the Vanguard engine? Do
you have the kit for sale?
A: Yes, we
have the complete installation kit and the 18 horsepower Vanguard
engine for your Case.
Q: We have a Case Model 444 with a Kohler 301 Engine installed.
I realize this is the wrong engine for this tractor. The engine is
bad. The tractor is in fair shape and everything works. What would
be the most practical engine to use for replacement or should we
rebuild the 301? Will probably use this tractor for snow plowing and
general utility. I have other mowers. If I replace the 301, what
would fit with the least modification?
A: We have
the new Vanguard V-Twin overhead valve 18 horsepower engine that
will fit right in your chassis without much work.
Q: I was splitting wood today with my case 448 garden tractor
and turned my 18 hp Onan twin engine into a single. Broke a rod.
Amazingly it still runs. I saw your conversion. Do you have a kit? I
would swap everything myself, but I wanted some options.
A: Yes, we
have it all in stock. I have the Vanguard 18 horsepower for your
Case 448 that is actually a short 20 horsepower and we also have the
installation kit. An additional kit I have put together (optional)
is a PTO electric clutch, special shaft and PTO switch. You do not
have to do any hood cutting.

Q: We have a Case 224 garden tractor with a blown engine. Do you
have replacement 14 Kohler engines for this tractor? Or, do you
offer a repower kit for other engines for this unit?
A: Yes, we
have an engine that will fit right into that tractor. I have a new
V-Twin Vanguard, overhead valve, 18 horsepower engine, installation
kit, and an additional electric PTO clutch kit if you would like to
add that also.
Q: I wish I would have seen your website about a year ago. I
have a 1984 Case-Ingersoll 446 garden tractor. The engine was tired
so I replaced it with an 18 horse Onan. Overall the switch over went
fairly well, but I cannot get the clutch (so called EZ adjust!)
right. Maybe it needs some new parts, but it just seems like a bad
design. You mention a switch over to an electric clutch, what is
involved in that?
A: Sorry, my
switch over kit will not work with the Onan engine. I have talked
about manufacturing a kit to go with the Onan engine but have not
done so yet.
Q: I have a mid 1970,s (yellow) Case 446 garden tractor
originally powered by an Onan 16 HP engine. I would like to rebuild
a Kohler KT17 to replace this, however, the KT17 has a threaded
shaft and needs to be replaced with a keyway shaft. Can you suggest
crank data - Diameter, Length to block, length of 1/4" keyway,
tapped to?, etc? Or perhaps you are aware of a spec number of a KT17
used by Case to power the 446.
A: I would use your original
crankshaft, put on a love joy, drill a 1/4" hole through the love
joy and through the crankshaft and drive in a heavy duty roll pin.
Do not waste money on buying another crankshaft. But as far as I am
concerned, you are starting out by wasting good money working on a
KT17 Kohler. The is the the worst or either one of the worst engines
ever manufactured by Kohler. What we do offer is a V-Twin, overhead
valve, Vanguard engine that fits right in those good solid Case
tractors. They are about 50 lbs. lighter than the original engine.
When you get this engine in and go for your test drive you will
almost think you have put power steering into the tractor. This is
just an additional bonus along with other big advantages to doing
this clean, neat job. We use the Vanguard V -Twin 18 horsepower to
repower this Case tractor. I also offer another additional kit if
you want to convert that old mechanical PTO clutch to a finger tip
control electric button controlling the electric PTO clutch.

Q: I have a Case 446 garden tractor and have a few
questions. Do I need to modify the hood for clearance? Is there room
for me to fabricate some exhaust pipes to use the original muffler
set-up? I'm going to rewire the tractor so is there anything I
should know concerning the electric clutch or electronic ignition?
A: With my
engine and kit
you will not have to cut anything. For your
original
exhaust we offer some exhaust plates that go on to the heads and
then
you just weld the pipe onto it. Also available is a complete
Vanguard exhaust
that bolts right on. If you are going to rewire the tractor I would
wait until you
get the engine in. Yes there are some wiring differences.
Q: I have a 1981 Case 446
garden tractor and it runs. However, the engine leaks oil, runs hot,
blows the fuse, and the carburetor probably needs to be rebuilt. I
see that you recommend the
Briggs Vanguard and have a kit to
fit it to my tractor. Does this require any modifications to the
hood or grill? How involved is this conversion and would you
recommend any bigger engine?
A: With my conversion you
will not have to do any cutting on the hood or grille as it all fits
in nice and neat. The Vanguard 18 HP fits in real nice and I have
them in stock, they put out a short 20 HP. The Vanguard engine will
give you more power than you currently have. We can install it for
you or we can ship everything to you so you can do it yourself.
Q: I read the
article in farm show and thought I
would send you this note regarding my 466 that I replaced the 16 hp
Onan engine with an 18 hp Onan about 20 years ago. This is an older
“yellow” one that has the hand levered clutch in front with the
plastic fan on it. I have always wondered if it would be possible to
put an electric clutch on it, as the original has never worked very
good?
A: Yes, when we do an
engine transplant we convert it over to an electric clutch and also
have to wire in a PTO switch.
Q: I am seriously
considering the
Vanguard engine repower.
Other than re-machining the adapter plate for the hydraulic pump
would there be any other modification? It would need an electric PTO
on the forward side or a shaft stub to allow the PTO clutch to be
mounted from the Onan engine. My only concern is that from what I
have found out about the repowering with the 21 HP Kawasaki engine
the hood has to be raised 2 inches and cut out or stretched at two
points on the side. I want to avoid this and that is why I am
considering using the Vanguard. I have the capability of machining
the pump adapter plate if that's all that is necessary. That being
the case If I can't get the Onan running.
A: Yes, there are more
things to do, you would have to rework the exhaust system I would
send you. If you wanted to reuse your old PTO clutch I may be able
to get that set up for you. Of course the electric PTO is a far
better set up than that old style Case PTO clutch.
Q: Would you repower 'kit'
also work for a Case/Ingersoll 648 loader tractor, originally
equipped with an Onan engine? Will any cutting or
modifications need to be done to the original hood, and will the
hood still hinge and lay flat on the front grille as was the case
with the Onan engine?
Also, will any mods to front grille or hood be needed to adapt the
exhaust pipes, muffler and exhaust pipe to the 648 frame when using
the Vanguard application?
A: I have the
kit with the Vanguard engine
that should work fine on your application. You will not have to do
any cutting on your hood. The hinges can also be left in their
original position. Our exhaust comes out the right rear side so
there is no need to cut any of the grille.
Troubleshooting the Case - Ingersoll garden tractors
Q: I have a Case 446 ( 1980
model ). It will not go forward or backward in low gear. Hi gear is
O.K.
What could be the problem ? Is there a repair kit ?
A: Your hydraulic pump and
hydraulic motor is in okay condition. It sounds to me like rear end
two speed problems.
Q:
I have an Ingersoll 448. I've tinkered
with this mower for years now and it's been very reliable. Recently
the battery light has been staying on, lights are dim and the
battery eventually runs down and needs to be charged to start it. I
just replaced the rectifier/regulator and it still stays on. There's
a little metal capacitor looking device with 3 wires (1 going to the
starter relay, 1 going to the battery light and 1 going to the
negative battery terminal). Do you think this part is bad? I guess
the key switch may be involved too as I look at the wiring diagram.
What do you suggest?
Also, this mower surges when running.
It's a steady constant rev and decline. when I mow, I don't notice
it at full throttle but when i slow the engine it begins again...
hot or cold. I noticed that when it pulls itself under a slight
load, it quits too. The only other remedy is to pull the choke half
way out and it idles smooth. I changed the fuel and air filter and
it still does it.
A: I think you need to check if
the center wire on your rectifier is hot with the ignition on. If it
is not hot, that is your problem. The second test you need to have
an AC voltmeter and check the two stator wires with the engine
running and they should be putting out 24 to 36 AC volts. If it is
not the stator is junk and I would not fix that as it also sounds
like you are having Onan governor problems.
