Info needed: Smiths "Maxfield" tranmission compressor- What vehicle?

[Jacques Reed]

Just to add:

The pump turns over freely but I noticed I could not fully disengage it- gear to rear of pump position. Seems the spring mechanism at the selector fork only allowed it to move slightly back and forth on the pump crank gear and not fully rearward and off it.

I removed the spring and it slides smoothly off the crank gear. It may need attention at the selector shaft and fork. It is not good idea to drive a vehicle with a transmission pump still in gear!

Cheers,

I know the Austin K5 4x4 had that pump fitted because I had a K5 drivers handbook, I passed the handbook onto a K5 owner in the UK.

Certainly the pump and mounting were a standard British item but I think that the gears were specific to the truck it was mounted to. The PTO flange mount on gearboxes was standardized but I am doubtful if that included the gear inside the gearbox that the PTO meshed with.

Yes that's true plus depends on where the pump mount is , it might be on either the LH or RH side of the gearbox

More on both English and Canadian/US PTO Compressors in THIS THREAD, including this Smith's Pump used on Austin K5 trucks.

While the Austin and Morris pumps are "Handed" differently for fitment to opposite sides of the gearbox, I think the pump end could be disconnected from the PTO adapter and swapped to the Morris PTO.

If I remember right the two cogs in the unit remain engaged, it is the large cog and the gearbox cog that get engaged to turn the pump on.

Hi Robert,

Thanks for that info.

It obviously doesn't have to move too far to disengage from the transmission gear.

I reckon the gear only moved slightly more than the width of the gear but that would be enough.

Paul, on that basis you have even less to do when you receive it. Just put the spring back into position on the selector fork. I've already packed it up otherwise I would do it for you.

Cheers,
