Chevrolet 1533X2 30-cwt trucks

[paul Lincoln]

Tony,
LRDG Chevs came from a batch of 200 vehicles to replace their Fords in March '42. When they lost many of them in Sept '42 they had to get the old Fords out of retirement as the replacements were lost at sea. Vehicles seen in photos with wooden bodies were 1311 15cwt trucks used by patrol commanders, medics etc. The 1533 body was an all steel ammo body made by Gotfriedson, or some very similar name. no time to confirm at present.
I can get you info on the converterd Chev in UK and LRDG preservation Society in US have a couple. The UK truck has a Dodge 3 ton rear axle with 2 speed diff and a Ford CMP front axle from a 15 cwt. A friend of mine has a Chev like yours and he has just started the conversion. He had a near perfect example of this truck, but it was too good to mutilate. He sold it to another enthusiast to keep it in good order.

You can send a PM to Clive on this forum to "Servicepub", or purchase the CD through his website.

G’Day from NZ ,
Three of us here are creating replica of a 1942 LRDG Chev 1533X2 30cwt truck (the long-nosed kind with the “art deco” grille). Ours is based on a 1945 truck, which we assume was partly built in Australia as it has GMH stamped on some parts. We are having frustrating problems obtaining the correct engine mounts and wonder if anyone in the forum can help. We ordered new engine mounts from a US supplier but when they arrived they were too big to fit between the bell-housing and chassis so we had to return them. We showed them photos of our old original mounts (see attached photos - they cannot be used as they are in poor condition) and they said they had never seen that type before and cannot supply them. Then they sent us another kind of engine mount that was smaller and did fit between the bell-housing and chassis. Both types from the US are made of steel with a vulcanised rubber pad inside.

However we cannot use the new US engine mount as there seems to be a deficiency in its design. It seems to us that engine mounts should include a “male” part that is attached to the chassis and which fits inside the “female” part that is attached to the bell-housing (as shown in the pic) with a rubber pad between them to cushion the vibrations. However no “male” part was supplied and on enquiring to the US supplier they don’t know what we are talking about. This is very strange, because if we use the new US engine mount as supplied, it will be a metal-to-metal connection and the rubber part will have no cushioning or damping effect at all. In the attached photos of our original mount, the red "male" piece fits inside the black "female" piece as shown.

So can you please tell me:

(1) Do Australian-assembled Chev trucks of that era have different engine mounts from US and/or Canadian trucks? Or maybe civilian trucks had different mounts from military trucks?
(2) Can anyone supply me with a photo or diagram of the correct engine mounts for our 1942 Chev truck? I cannot find a drawing even in an original service manual.

I have searched the forum and seen a diagram in another post showing one kind of engine mount that has no rubber, but uses springs instead. However I am not sure whether that is suitable for our truck.

It would be great if someone could put us on the right track.

Andrew are there any markings on the mounts?
Here is a picture that I recently grabbed from trademe

most of those Chev trucks were built by GM Canada and are not US ones. Holden only assembled them and made a few parts BUT chassis and running gear were Canadian I believe.

Hi Andrew

Finding CMP parts or Militarized Civilian Truck Parts is an interesting challenge as you well know. Don't know which US parts supplier you are dealing with but most if not all of them really are geared to dealing with cars and pickups.

The following is out of the Canadian Chevy Truck Parts Cataloque 1938-1951 it gives information on engine mounts parts # and which trucks they fit as a starting point.

Could you post a picture of where the mount bolts on to the transmission and the cross member that it sits on?

Is this the engine mount you found "I have searched the forum and seen a diagram in another post showing one kind of engine mount that has no rubber, but uses springs instead. However I am not sure whether that is suitable for our truck. "

From the note at the end of mount section I would take it that they routinely replaced the rubber mounts in rough service with the spring units.

Hope this helps.

Cheers Phil

Thanks everyone for your prompt response!

Lyn: There are no markings on the original mounts (so maybe they are not original?).

Cliff: Our truck is definitely made in Canada as the data-plate says so. However some parts are stamped "GMH" indicating parts were added in the Holden factory in Australia before being shipped to NZ. It is the militarised version with the wooden steering wheel and army instrument panel.

Phil: Thanks for your helpful and very comprehensive reply. Yes your diagram is the one I was referring to. Am I correct in thinking that that type of mount was used in trucks used for "heavy duty"? If so, then the LRDG trucks would surely have used that type of mount? The attached photo shows the cross-member with the original(?) "male" mount at right and one of the new (female-only) US mounts at left.

Hi

In the drawing it is hard to see but there is a tube spacer between the top and bottom of the cross member to keep the rear engine mount from crushing or deforming the cross member. Dose your have this spacer and the reenforced bottom?

Cheers Phil
