Q: What is the recommended
engine for a Bobcat 600? Do your kits come with everything I need?
repower engines have their own
charging systems or will I retain the jackshaft-driven alternator?
A: We do our best
to furnish you with everything you will need to make the conversion.
I would recommend the Vanguard 23 horsepower engine and the
installation kit. No, you do not have to worry about keeping your
old charging system as this will already be included in my package.
Q: I have an old Melroe
Bobcat model 500 that has a sick Kohler engine. I have the engine
out and was ready to go through it when I came across your site. How
Vanguard engines tolerate the
crankshaft load on the belt drive side? The Kohler has a very large
tapered bearing in addition to the babbit main bearing. Does the
Vanguard have this kind of crank support also? With the crank being
smaller I am concerned about how they would hold up. Also, how does
the hydraulic pump hook up to the opposite side of the engine? I
have machine shop capabilities as well as equipment so I feel I
could do the project myself with some direction.
Even our smaller 23 horsepower
Vanguard engine has a ball bearing crankshaft. Of course the 31
horsepower is just bigger yet with ball bearings. I already have
many Vanguard engines running in skid loaders, and have been
repowering them and garden tractors since 1988. These are the
Cadillac of air cooled engines that include a commercial warrantee.
I also have the stub shaft kits in stock so that is no problem
getting power off the other end, meaning the flywheel side. We also
have different types of exhaust systems available so we can fit to
Q: I have a late 70's early 80's 632 Bobcat with the Ford 1.6L
in line four cylinder engine. I had heard there were various
conversions available for stronger and more reliable engines. In a
web search, I came across your web site. Have you done replacements
for these engine before?
Yes, and I would recommend the new 31
horsepower V-Twin Vanguard to repower your Bobcat.
Q: I have a Bobcat 630 with a Wisconsin VH4D 28hp engine
with engine problems. I was told that ONLY Bobcat put a tapered
crankshaft in their WI VH4D 28hp engine, so if I want to put a used
WI VH4D in it, it won't work. Have you heard anything like that?
Also, What about the VG4D 37hp WI engine. Would that fit?
A: I have a
31 HP, V Twin, overhead valve, Vanguard engine
which would have plenty of power to handle your job. I would have to
check into getting the taper machined into this current shaft to
equal your current taper on your Wisconsin engine.
Q: I have an old Bobcat
520 skid loader and engine has gone out in it. The engine has a
crack on it. Do you have any ideas how I may repower it without
spending more than I paid for the machine? Does the Vanguard 18 hp
engine have an electric starter and an air filter and fuel tank and
fuel pump? I need to know if there is anything that is not included.
I also need to know if with the engine and the conversion kit come
with an installation manual or notes? What is the availability and
how fast can it ship?
A: Well I don't know how much you paid for it, but I'm sure
it would cost a fair amount to replace the skid loader. I have the
new Vanguard V-Twin, overhead valve, 18 horsepower engine. This
engine actually puts out a short 20 horsepower. Yes, these new
engines come with the electric starter and a charging system to keep
up with the running lights and keep the battery charged. It also
comes standard with a heavy duty air cleaner and also has it's own
fuel pump. It does not have a gas tank but you can use your existing
one, or I have gas tanks available if you do not want to use yours.
We currently have everything in stock, the engines and the different
kits. With each machine being unique, instead of instruction manuals
we offer our customers phone and or e-mail support almost any time
of day, toll free. You can just give me a call and I can talk you
through most situations.
If you want me to send the
engine and kit give me a call on my
toll free number, 1-800-618-8738. I need to ask you some questions
so I can figure out what to send you to get it as complete as
possible on the kit subject.
