Default CMP fuel pump and dizzy????

Has any one ever seen a CMP fuel pump with the metal bowl on top instead of glass.........BUT with a hand lever on the outside that allows to hand prime the pump........ I have one onmyMassey diesel tractor circa 1974....never seen one on A CMP......

Question number 2........ ever seen a 216 distributor in which the inside plate that holds the points/condenser si "isolated" from the mainbody of the dizzy and has a separate connection for grouding the plate....... the inside has a semi circle of black plastic that prevents the clip mounting bracket screws from grounding the bottom plate.....??? I am trying to get a better picture to see the serial number from underneath the condenser.........Could it be for a radio truck???

Curious????

Default 1110090

Hi Bob, all I can find is part #1110090 changed to #1112353 on 7-1-50. When I tried to find the #1112353 my parts book said removed from service. It would be interesting to know what it was used in.

Default Distributor

Hi Bob, it seems that the number 1110090 is a 216 distributor from 1940 to 48 and the 1112353 distributor is 1950 to 52. I found another distributor on EBay with the same insulation on the plate as your distributor.

Default Here is reply from a Dekco-Remy site....

Never heard of a polarity reversing switch on a CMP but engine in CMP frame was not original 216.......

Thanks guys.


Posted 5 hours ago
1941-1942 Chevrolet 216. Those years had a reversing switch that changed polarity to the points each time the starter foot pedal was activated. The theory was to prolong point life. After frequent failures the switch was bypassed with a dedicated ground to the plate terminal. Note that points with a different part number are used in that distributor. 7L2 is probably the date code. December (L) 7, 1942

Default Fuel pump with a hand primer pump built in....

Probably civilian market for specialized application such as a standby unit or other static application where the engine may not have been started often.....but it does fit on a 216 engine block.....

I think that I have one of the CMP fuel pumps with metal rather than glass fuel bowl (either at home or the barn) but it definitely doesn't have a priming lever.

Default Gmc cckw

The WW2 GMC CCKW pump has a hand primer and metal bowl, it will fit a Chev 216. But looking on-line, rebuild kits are no longer available and NAPA sells a replacement pump . Part No. AC-429 - no hand primer though.

My C8 has the original 216 engine, I fitted a GMC CCKW fuel pump with a hand primer and metal bowl, I bought the CCKW pump NOS many years ago from Auto Surplus in Mitcham . Holden ( local GM car ) Red motor fuel pump kits might fit the earlier GM AC pumps, being AC brand. Side by side , a Holden fuel pump looks to be identical to a older Chev pump.

You need to find kits that are suitable for modern fuel.

New CCKW pump from the Netherlands.

I’ll dig the parts out in a bit to better show.

The early CCKW and Jeep engines both used a 2 valve fuel pump with primer levers and metal bowls. From my understanding the only difference was the actuating arm that rode on the cam was different. One arm pointed up and the other pointed down. These are the same fuel pump that Chevy used just minus the priming lever. The good news is that the Jeep portion of the hobby has almost everything available to them. Joes Motor Pool products reproduces both the Jeep fuel pump and high quality rebuild kits. The rebuild kits will work with the Chevy 216 pumps.

My Jeep has a fuel pump with the primer and I love it. When the Jeep sits for a time, I can easily give the pump a handful of pump ups and I’ve got fuel right up at the carb. I’ve got an original CCKW fuel pump to rebuild for the Otter project. I also bought a new made fuel pump with the priming lever to fit on my C15A.

Here is the link to Joes Motor Pool fuel pumps. Most of the Jeep parts vendors sell their products as well.

That is useful information. Yes you can buy just about everything for a MB GPW now.

Default Are you saying.......

Hi Jordan.....

Are you saying the rebuild kit for a Jeep fuel pump (Hopefully made with a modern rubber diaphragm) will interchange for rebuilding a CMP Chev pump???

Interesting interchange........ as we all know that the Jeep PCV will fit a CMP and so will the horn rubbing block on the steering shaft....

What else fits a CMP???

The pumps are all basically the same. Itís just the actuating lever that goes into the engine and rides on the came that are different. So you need to change that out


Bob, anything will fit if you hit it hard enough

Default Yup......

....got some big hammers in the barn........

Original Chev parts do surface on Ebay and FB Marketplace....particularly the French PQ area parts postings....some what geographically limited and the asking price are more reasonable.

Good job on the big turtle ........ would love to see the guy's face that does the safety for registration........ but I know you have an ace up your sleeve.

Cheers

Bob,

It would appear that Chev CMPs started using fuel pumps with priming levers during 1943. Please see attached image from Spare parts list C15-03.

It also appears that the fuel pump bowls were metal: https://www.lwdparts.com/product/fue...-ac-fuel-pump/

...found it in my later published April 44 C60 book

The funny dizzy was on a 1942 C15a........ it explains the funny rotational switch on the stomp starter that allowed the polarity to be changed each time the truck was started.....said innovation only lasted 40-42 on civilian vehicles.

A bell housing from a civilian Chev 3 speed ( late 40s) has now been found that fits the 216/235 and will take a SM420 dirtectly bolting on....... it is a left hand clutch bell housing but will be modified by cutting a fork window on the right hand side and relocating the fulcrum bolt to an existing reinforced bulged in the RH side
( to be drilled and taped at 7/16)....obviously the bell housing was also meant for export....will be guided by Phil W. instructions who as done the mods in the past.

Cheers
