Puller Frills

[olin r. boyer]

Don't remember who it was that suggested the 1/2" 8-point
socket for cranking the 4-square top of the OTC927 puller,
but it sounds like a good idea if you can come up with a
"thrust bearing" for the other end!

I had a brain-storm while out driving today, and couldn't
wait to get home and see if one of the Alcoa lug nuts would
fit the bottom of the puller! Unfortunately, like most of
my marvelously inventive ideas, it didn't. Seems the lug nut
is 1/2 inch and the bottom of the puller is threaded 5/8-18.
Too bad --- the built-in washer in that lug nut has a
"built-in" thrust bearing!

Anyone have a suggestion (make or buy) for a 1 1/8" collar
that would couple a lug nut to one of the steel "crutch
tips" that is already threaded 5/8-18? (two of the steel
tips came with the puller).

On another subject --- while looking around under the front
end of my coach today, I noticed a couple of "polished"
areas ~1/4" wide ringing the drive shaft that passes under
the oil pan. Looks like the shaft might be contacting the
pan in a couple of places. Is this normal? Should I be
concerned? Should I "lube" the spots until I can see about
getting it corrected?

Sorry about that... The lug nut is 9/16" (still smaller than
5/8-18)

Olin:

Don't give up yet on your thrust nut idea. Just because the nut for our coach
isn't the right size doesn't mean that there isn't one for another application
available. Contact your Alcoa supplier and ask if they have the size you need.
Let us know the part number then.

Sorry I brought up the subject of Thoma. There was no
offense intended, nor were my remarks meant to be
disparaging of your puller. I bought your puller because I
thought it was a marvelous design, and that it would be a
tremendously good buy! I still think that, and am proud to
own it! I am merely trying to assemble any ancillary tools,
equipment, gadgets, etc., that might be of some help if I
should have the need to use the puller on the road.

Today, I bought a 1/2 in drive 8-point socket to fit the top
square of the puller shaft. I also bought a 3/4" to 1/2"
adapter so I can "crank" the puller shaft with my 3/4"
sliding bar lug wrench, or if need be, the 300# clicker
torque wrench that has a 30" swing. The 1" drive nut I can
handle with a 1" open-end wrench. The wrench is only 12"
long, but I'm sure it will rest against one of the upright
puller bars to offset the longer wrench that I will use on
the 8-point socket. I really don't think I could come up
with any more "puller power" with an impact wrench... using
Thoma's puller or anyone else's. When I look at the diagram
in the 7525 maintenance manual that shows the positioning of
the "C-clamp' that was apparently needed to use the GMC
puller, I really am impressed with how far forward you have
brought us with the Warner puller!

As I've mentioned before, I bought a slide hammer and made a
strap to fit the lugs so I can pull the hub from the knuckle
just like the maintenance manual tells me to, but.... I do
hope you will find time to develop the "plate" for use in
pushing the hub from the knuckle. I want one, and I know a
lot of other folks do, too.

Thanks, Tom
