Ford Long Shafted Starter Motor Replacements
Posted 6/30/07
I am disappointed to announce that there will not be an adapter plate for
the TB series of Injoy motors, making them "plug and play" with the Ford starter
motor....or at least not available in the near future. The shaft of the
motor would need to be around a 1/4" longer than the now 6-1/4" in length from
the mounting surface of the motor. I'm not sure, right now, that I want to
do that. I have 30 of these motors in stock right now and I have to eat
through those before I can stock any motors with the longer shaft length.
You might be interested to know that the shaft length for the Ford starter
motor, from the mounting surface of the face plate, is 6-1/4," not the 5-3/4"
which is the shaft length that is usually used to describe the motor. The
5-3/4" shaft length is measured from the front of the bearing housing on the
face plate...makes a big difference.

The test results for the Injoy TB series of motors are in from Jim Brandon
and the boys at Olathe...check out the responses on the
rcgroup. I am still on track to have the Ford hole pattern adapter
plates for these motors the first half of July.

Jim Brandon had an opportunity to test the TB1225 out in the field with his
sailplanes this week. The results as he describes them are "subjective,"
but the motor performed at least as well as the Ford and maybe a little
stronger. He will be posting his test results on the rcgroups in the next
week or two.
I also sent Jim one of the TB1248 motors which he also tested out in the
field with his planes. To quote Jim,
"I put a winch together last
night and used the 1248 motor. All I can say is WOW! This is the first winch I
have been afraid to launch from. It pulls very hard – all the way up.
Absolutely no bog down, the motor just whispers all the way up." He will
be testing his winch with the TB1248 with some of his buddies that fly moldies
in the next two week.
The TB1225 and TB1248 motors will be available in the future with an adapter
plate for the Ford 3 hole mounting pattern.....available in July 2007.
The motors will then be "plug and play" with your Ford winches so they will fit
the Tim McCann winch kit, "pre" and "post" 2007 models.

I have some new test results in from Jim Brandon of Gladstone, MO.
Being from MO, he is a true "show me" kind of guy....so he purchased one of my
TB1225 motors and has started assembling a winch. Jim also has a friend
that earns his living rebuilding motors and has a motor test machine used in his
business.
Jim has been testing the Ford 3110 and 3115 motors at his friend's shop for
the past few years and has been keeping a database of the results. This
past week, Jim took the TB1225 motor over to his friend's shop and they ran it
through the various tests that the machine performs. The results were great
when comparing them to the results for the Ford 3110 and 3115.
The TB1225 tested out at slightly more than 2.5 HP under load with a
comparable RPM to the Ford 3110 under load. At this point I feel confident
in telling people that the TB1225 will perform equal to the originally manufactured Ford 3110 starter
motor. I look forward to hearing from Jim when he starts using his new
winch out in the field with his flying buddies. Thanks, Jim, for being
willing to be a pioneer. You can follow Jim's progress
building his
new winch.

Tim
McCann is sending me a prototype winch to use for the upcoming field tests
launching sailplanes. I will be testing two different motors...one rated
at 2.5 HP and one rated at 4.8 HP. These motors are standard production
motors used for various commercial and industrial applications but with short
shafts. I was successful in convincing the manufacturing company to
produce these motors for Injoy with a 6" shaft. There should not be any
problems with having these motors rebuilt or serviced because the components are
pretty standard for a 12 volt DC motor.
I hope to start field tests at the end of April and in May. If there
are any clubs in the northeast (New England, NY, NJ, PA) that would like to
take part in these test, please e-mail me.

Tim McCann constructed a fan dynamometer to place a load on the motor and he
then measured the RPM under load. He measured the Ford 3115 with needle
bearings, the Ford 3110 with ball bearings, and the new TB1225 with ball
bearings. The results are as follows: the 3115 produced 2340 RPM;
the 3110 produced 2640 RPM; and the TB1225 produced 2320 RPM. While the
fandyno placed the same load on each motor, it is unclear as to how this load
relates to the load placed on a winch motor when launching those big, hard to
launch planes now being used in open class competitions. Only field
testing with the "big" planes will determine if the TB1225 is a possible
replacement for the disappearing Ford 3110 motor. This will probably not
happen until the winter snows disappear.

A
sample motor, built to my specifications, has arrived. It is rated 2.5 HP
with four field coils and ball bearings front and rear. The motor looked
good enough with a bench test that I ordered a quantity to be built by my
supplier. Today, I shipped the sample off to Tim McCann for rigorous field
testing and to compare how it performs against the Ford 3110 starter motor. I
will report his findings as soon as he has a chance to complete the testing...I
expect that he will post the findings on his
Superskeg website, also. The price for the motor will be $290.00
To my lure machine customers, Tim McCann will be testing the motor by using
it to launch various size sailplanes. These tests will give me a good idea
as to how this motor will perform when used on a lure machine. As the snow
has finally arrived in Vermont, it could be 3 or 4 months before I am able to
test the motor on a lure machine.

The hunt for some newly manufactured motors goes on....and on, and on.
Actually, I'm making pretty good progress...it just takes time when you are
specifying how you want a motor to be built. Some of the information
I gave you on 12/06/06 below, has proved to be inaccurate. The following
is the new information as it stands today.
I have in stock, right now, newly manufactured 3115 and 3110 motors.
These are the original Ford design and not the Prestolite style as reported in
December. For the time being, the price for each of these motors is
$125.00. The future availability of these motors is unknown at this time.
I
have specified a new motor to my supplier, that I will be using for all of my
lure machines and it should work great for my sailplane customers. The
motor has 4 field coils (3110/3115 motors have 2 fields) with a rating of 2.5 HP.
The 4 field coils will provide more torque than the Ford starter motors with
about the same RPM. This motor will have a four hole mounting plate like
the motor shown in the picture at the right. And, the exciting part is
that the motor will have two ball bearings (front and rear) installed with a
selling price under $300.00. I am hoping to have these motors in stock by
the end of January.

Historically, we have used the 3115 Ford starter motor to power our lure
machines. This motor is a 12 volt starter motor with a 3 hole mounting
plate and a 5-3/4" long 5/8" diameter shaft. The 3110 Ford motor has the
same physical dimensions but is a 6 volt starter motor and the field coils are
made with heavier (thicker) copper strip. This motor can be run on 12
volts and produces more speed and power than the 3115. If you ask for a
3110 starter from the local parts store, you may receive a 3115...the only way
to tell, is to examine the copper windings.
For the period of 2002 to 2006, I have been selling a new 3110 motor that
was being manufactured in India. These motors are no longer available
because the company in India has gone out of business. I am currently
testing new 3110 and 3115 motors that are being newly manufactured in the
US. These are quality motors that are manufactured in the Prestolite
Style. This means that the motor brushes are not installed on the end cap,
but are installed in a separate bracket inside the motor. This makes no
difference for my lure coursing customers, but for my sailplane customers, you
will not be able to use the Real Balls end plates. Unfortunately, the cost
of these motors are going to be more than the $125.00 that I am currently
charging for the India motors.
Sailplane pilots, not to worry. The 3110/3115 motors are rated at
around 2+ HP. I can purchase motors rated at 2.5 hp and 4.6 hp that have
sealed ball bearings installed in both ends. Unfortunately, these motors
will not have the 3 hole Ford mounting plate but instead will have a two hole
mounting plate, 180 degrees apart. It appears that I can sell these
motors, with ball bearings installed, for less than a set of Real Balls would
cost. They will not have the sexy fins on the Real Balls end plate, but if
you can live without the sex, these motors should be boss.
