The Stovebolt Site Forums The Parking Lot Big Bolts Updated pics for 51 GMC tanker

Hi all,

I have a confirmation date for the trailer tuesday of next week. I had to go up there for a meeting today so I took some more pics and put them in my photo bucket. Tell me what you guys think about the Parts ID tag and what you know about the tranny and diff. Also I got a better pic of the wheels so you can give me advice on how to deal with them. Is there anyway I can use the old PTO for a dump flatbed? 51 GMC minus tank

It is a Clark 460 steering axle which became obsolete not long after this truck was built, but bearings are still available. The transmission is a Clark 5 speed 202V with a direct 5th. First is away from the driver and towards the seat. Reverse is away from the driver towards the dash. This was considered useful when the vehicle got stuck. One could rock back and forth between 1st and R. The drive axle is a 16600 Eaton 2 speed with 6.50/904 ratios. This rear was used for another 30 years or better. The PTO should work with a hydraulic pump for a dump. The wheels are hub piloted with Goodyear style rims which is a good thing. The tires don't look all that bad. And bias tires don't blow out from age like Radials. The tread design looks like Goodyear of about 25 years ago. The thing on the rear axle is a backup alarm. A bell rings when the vehicle moves backward.

Wow I didn't know they had back up alarms back then. Thanks for all the great info. What does it take to remove those tires?

A tire hammer or bead breaker, a couple of long tire irons and someone who knows how to use them.

Had either the same Trans or a similar one in my '62 GMC 6500. Used that First and Reverse routine many times with that Trans when I would get stuck in the mud.

Actually I meant taking off the wheels, I would take them to a professional to put new tires on. Removing the tires is like any other truck? Nothing dangerous?

A large impact would be nice, but a socket and a "cheater" pipe will work. Be careful with a cheater though. People have slipped off and knocked their teeth out. Other than that it is just common sense. Don't let it fall of the jack, and use jack stands.

Any idea on what tires cost for that size?

Looking at your pics on Photobucket. According to that tag, the pump on your tanker was made by the Gorman Rupp Company in Mansfield, OH. I live just 6 miles from that factory which, judging from the cacti in the background, is just a bit closer than where that pump is now. Very cool.
