Air Brake trolley hand brake control valve rebuild kits FS
Hi All,
I am looking for the hand air brake valve that mounts on the steering column of the Diamond T. That or a repair kit that has the seals.
Has anyone had other options for repairing these?
I understand these the same on the Ward LaFrance Wrecker, Pacific Dragon Wagon, High Speed Tractor, essentially any MV with air brakes (or uses it for a trailer as with the HST).
Thanks,
Dave

Thanks. Good to know.
What have people been doing to get them working again?
There are a couple rubber parts inside that get all dried out.

Hi,
With all the WWII MV's out there with air brakes using this valve someone must have a replacement kit or way to rebuild them.
Any help appreciated!
Thanks

Re: WTB Air Brake trolley hand brake control valve or repair
Dave,
I hope you are not being ignored, rather that you have asked a question no-one has the answer for.
This valve is the only one that I have not had apart on my DT969. Here is the exploded view from the parts manual . . . .
. . . . . and the listing for the kit.
The 'Ball' is item G
The 'Cup; is item U
The 'Screw' is item B
The 'Spring' is item F
The 'Spring' is item AB
The 'Valve' is item X
Hmmm, the kit does not seem to have any rubber parts except maybe the Cup. Strange.
It is not much, but maybe a European dealer may have something to help.
Please let us know what you end up doing.
Sam.

Re: WTB Air Brake trolley hand brake control valve or repair
Sam, thanks for responding and offering the info. I appreciate it.
So my solution to get the trolley hand brake controls working again were to make my own rebuild kits.
I had all the rubber pieces molded using an NOS kit as a template. There are 3 rubber parts in the valve.
The company machined molds from the original parts and molded brand new rubber pieces.
I had new springs made as well.
The sealing surface on the plunger was pitted on 2 of my valves so I had them welded up and then I turned them on my lathe to spec.
The new hand valves work great!
The truck also has double check shuttle valves, so I made new seals for them too.
I made extra pieces so I have some rebuild kits available if anyone needs them.
Thanks,
Dave

Here are some pictures of the valves with new rubber and spring going back together.
There is a special graphite lube (as per the TM) on the seal so it looks irregular in the picture.
