Over the last several months I have provided over 110 front wheel bearing
pullers to GMC coach owners. As far as I can tell from talking to others, we
have provided more front wheel bearing pullers than all other sources
combined. And without the GMC net it would not have been possible. Its all
been by word of mouth or via email. I receive letters (and checks) now
everyday from GMC coach owners that have heard about it through someone
else. My hope is that the production of these pullers will eliminate our
front wheel bearing problems, since it will be very easy for anyone to
service them the right way. Every coach should carry one of these tools even
if you do not do the work yourself. Give it to your mechanic with the
instructions and let him do it right.

The price of the complete puller at $190 is far below anything else on the
market and it is a superior tool to any of them. The split rings alone now
weigh 8 1/2 pounds, and are beautifully tooled. I originally said that I was
only going to produce 10 of these things, but it has outgrown itself. I am a
great planner as you can see. As long as the orders keep coming in I will
keep having them made. My wife says I really need the work. Yeah sure! Ever
try and hand box 50 nine pound pullers and address them through UPS?

Several coach owners have sent me emails and personally talked to me about
making it easier to use, since a hub with an old bearing on it can be really
tough for even a big guy to remove. I decided to redesign the puller and
make it totally hydraulically operated. The shell is complete and even more
massive than the first ones previously produced so that it will accomodate
the hydraulic jack. The prototype has been tested using a 6 ton bottle jack
as the hydraulic source. It now is possible for a child to both remove and
replace the front wheel bearings of the GMC motorhome with very little
effort. I am now working on an attachment that will adapt to it to remove
the hub from the knuckle.

I believe I can keep the cost of the hydraulic version below $200 as before.

 
Dick if you can find a bottle jack that will fit between the two screws of
the assembled puller and the OTC927 than we can retrofit it. I have not had
time to check yet.

Hi, Tom,

Wouldn't a porta-power be ideal for this? I have long wished for a couple of
puller attachments for a porta-power cylinder to make a puller out of it; do
you suppose your friend could be induced to make some? A 4 ton porta-power
kit is quite reasonably priced--I paid a bit less than $200 for mine--and
this is something that would get a lot of use.

Sure that would do it travis but most would never spring for the two units
of around $$310. I am trying to make the best tool possible and still keep
it very reasonable

Tom, I haven't yet used my puller so I don't know how tough it will be with
the purely mechanical unit. I'm 6'-3" and weigh 234# -- and have two sons
about the same size -- so suspect we can get it done.
I'm pretty mechanical myself and can probably come up with something on my
own, but.
just for grins, could you share enough of the new hydraulic unit with the
gang so we might be able to cobble together a retrofit to adapt it to the
jack if that becomes necessary.

I was thnking about a 10 ton portapower from Harbor Freight. Not a great
quality piece of gear, but not bad - and the jaws should fit between the
two pieces.

I second that suggestion, Dick... I have been looking at skinny (inline
bottle jacks and have found a manufacturer Omega Lift (located in Taiwan!!!)
that makes three small jacks that might fit between the two holes that are
about 3.5 inches apart on the C collar ring. They are in the $20 to $30 range
at retail.

Omega Lift
http://www.omegalift.com

Hydraulic Hand Jacks
Available at 2 ton up to 50 ton capacity for "In-Line" and "Side-Pump" Series.
Serrated, heat treated saddle provides generous lifting area and secure grip.
Heat treated extension screw allows low pickup height adjustment and
maximum lift height.

U.S. Patented built-in by-pass device protects hydraulic system from
overpumping damage. Spring loaded handle ensures maximum pumping
force. A wide, rugged base provides stability and strength. All models
critical stress points are reinforced for added durability and dependability.
Cross type forged release valve assures positive control.

Specifications
In-Line Series
Model No. Capacity Min. Height Max Height Ext. Screw Base Size (LxW)

10020 2 Ton 7 1/4" 13 5/8" 2" 4 7/8" x 3 1/8"

The last dimension on each line is the width...

Anyone see any problems... Since you Tom, are already working on a
bigger one, what should we be looking at in particular?

John 74 Glacier
 
As soon as I get it finished I sure will.
