WTB Air Brake trolley hand brake control valve or repair kit

Postby dlevy » Mon Mar 20, 2017 3:23 pm

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

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.

Image

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.
