Hand pump bracket connection to rear seat on GPW
How is the bracket that holds the foot of the hand pump connected to the underside of the rear seat on the GPW? I bought some new brackets and there are some holes in the base bracket. Is it welded, bolted or riveted? the place where mine was has had a perfectly sized patch welded into the seat as if the old bracket had stress cracked a neat rectangular hole in the seat base.

Re: Hand pump bracket connection to rear seat on GPW
Original early GPW rear seats did not have tire pump brackets and they are actually fairly rare. If you have such a rear seat you would be making it less valuable by adding the bracket. Having said that, it sounds like you had a bracket there, but I can't help because I have the early version myself.

Mine is April 43 and according to all of the information I can find the pump was fitted in about February 43. The stud for the handle bracket has been broken off and the hole welded up.JAB wrote: ↑Tue Mar 20, 2018 8:31 pmOriginal early GPW rear seats did not have tire pump brackets and they are actually fairly rare.

Re: Hand pump bracket connection to rear seat on GPW
Does no one know how the large pump bracket is fitted under the rear seat ? spot welds, rivets, bolts?

Re: Hand pump bracket connection to rear seat on GPW
As stated above....the early seats with NO provision for the pump seem to be more prevalent. Why butcher one to make it a "late" when I am pretty sure there will GPW owners in your neck of the woods who would love to trade you a LATE version.
If you were in the Bay Area I would hot-foot it over to your place with one I have that has the brackets factory installed and trade you in a New York minute.
Oh yeah...the foot bracket is spot welded and the handle clamp is held with a stud similar to the one holding the battery bracket that is located on the fender or the one on the floor for the ground strap. Can you post a pic of the bottom of the rear seat? The M201 seat is similar but the foot pump mounting is much different...

Thank you for the reply. My GPW was fitted with a pump as it is April 1943, I would have thought your 108 would have a pump fitted, should it not?
The new bracket has 3 holes in it, I suppose they are so you can puddle weld it onto the seat with a mig welder. My seat has a repair the same shape as the pump bracket as if the old bracket had broken off making a hole in the seat. The stud has broken off and the stub is still there. I will post some picures later.

Re: Hand pump bracket connection to rear seat on GPW
My GPW-17963 should not have a tire bump bracket on the rear seat....I have two of the rear seats with the brackets, one currently in GPW-17963 and the other set aside for GPW-108552.
So, it sounds like you have a late rear seat someone butchered or damaged so reinstalling the brackets sounds about right. You can plug weld the foot bracket where the old one was and perhaps drill through the handle stud remains and install a section of threaded rod and secure it with a bit of weld under the cushion that you can round off. Be careful not to blow a hole through the seat pan when plug welding the foot bracket back on.
PS...check your tire pump to see if it fits the bracket BEFORE welding it to the seat...

Out of interest, what is the thread on the stud for the pump handle bracket?Chuck Lutz wrote: ↑Mon Mar 26, 2018 12:03 pmMy GPW-17963 should not have a tire bump bracket on the rear seat....I have two of the rear seats with the brackets, one currently in GPW-17963 and the other set aside for GPW-108552.

Re: Hand pump bracket connection to rear seat on GPW
I found this in my pictures file, which reminded me that I did have one with the bracket. The stud is a special part but I'm sure you can easily fix it like Chuck suggested. It's fully threaded, 5/16-18 X 1-1/4 such that 1-1/16" protrudes through the pan. The bracket appears to be welded only where the three holes are, which is odd because it's almost broken off like yours. If I don't fix it, it too will break off leaving a rectangular hole. The holes are about 1/4" or maybe a little larger, one right below the end of the tape measure and two more above it, almost in a line. Seems like a poor way to do it, but it's lasted this long. This is an F-marked seat pan (look below the tape at 9-3/4).

Thank you very much, that was exactly the information I was after and the reinforcement fo the theory that my bracket broke off.
Below are pictures of my rear seat. In the last picture you can just make out the circular edge of the hole that the stud went through to secure the pump handle

Re: Hand pump bracket connection to rear seat on GPW
Oh boy. You need more info to do the job properly. I’m off work tonight due to family issues but I should have time later to get you more accurate dimensions, including the head of the stud.

Hi,
I think you want a weld stud- something like this.

Shouldn't be too hard to find at a local hardware store or online hardware retailers.
Cheers,
Ian.

Re: Hand pump bracket connection to rear seat on GPW
Yup, that’s what it looks like. I’m going to be tied up for a while but if you need a specific dimension I should be able to get it
