Smiths "Maxfield" tranmission compressor- What vehicle?
 

Good Day,

A friend just gave me this transmission compressor. He thought if was for my Ford CMP truck. I don't think F15-A trucks were equipped with compressors but it would have been a nice accessory to have.

Don't think it is for it Ford CMP trucks as it as made by Smiths in England. My Ford Parts Manual says they were made by Outboard Marine, Saylor-Beall or Webster. It is also much larger than the one for the CMP transmission. It is all cast iron so quite heavy instead of the die cast metal ones used on the Ford transmission.

A quick Google search suggested a few applications: International K5, Austin or even Land Rover but no definitive answers Even a G-Well bag lifter which I haven't got a clue to what it is.

Any help with identification gratefully appreciated. Prefer to pass it on to someone who can use it.

Cheers,

Hi Jacques it looks very much like a pump that would go on my Morris C8 GS, I have half of the pump so will photo that half tomorrow and let you know. Looks good though.

Yes
 

Hi Jacques

I think these pumps were ubiquitous and were fitted to various British trucks. I have one from a Morris CS8 . If you don't have a use for it .... hint hint

Hi Paul and Mike,

Thanks guys for your identification of the pump.

I guess I better give Paul first offer since he was first in line. If you can use it it's yours for the postage. Heavy sucker it is though so may cost a bit!

If Paul doesn't want it its yours Mike. Same deal postage or pickup.

Cheers,

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,

Austin K5
 

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
 

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.

Jacques I would gladly pay the postage up to Hervey Bay QLD,
Many thanks
Paul

Hi Paul,

It is yours. Glad it can go to someone who can use it.

PM me your address and I will work out the postage cost.

Cheers,

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,
