Chevrolet 1533X2 30-cwt trucks

Thanks David,
So to be authentic there is only one type of engine mount we should be using and that is the small one with the bolt and spring and no rubber at all!
Correct?

[motto (RIP)]

Yes Andrew, I believe that to be the case. I do however shy away from making definitive statements because of the frequency with which somebody turns up with conflicting data. I can only go on what I've seen and I don't know it all.

I will say this though. You can't go wrong in using the small bracket with bolt and spring, that was definitely used on wartime trucks. The rubber mounts I would be doubtful about. It is possible that the rubber type rear mounting was used on lighter vehicles, I am not familiar with those at all.

Gentlemen, it seems to me, that the answer can be determined from the parts list posted by Phill.
Do we know the series of the truck?
Do we know the year it was built?
Who has the steel mounting brackets, and what part numbers if any are on them?
The one in Phill's drawing showing the bushing and washer is a #602787 this number does not appear in the other list which mostly identifies (earlier?) numbers in the 59xxxx range.
Is the 602787 one, an improved (stronger?) model?

Andrew, yes, the spring and steel mount is the CMP style (I recall someone posted about the way the bolt is fitted)
As David states. this arrangement can be used, with no harm done, and if more info comes to light later, then so be it.

Thanks Lyn,
I don't know the "series" of our truck but the data plate says it is a 1945 model and the attached two photos show it before we dismantled it. I think the engine number might also be relevant but its away being reconditioned at present.

And thanks also David,
I had to chuckle at your comment, as I also sometimes confidently make definitive statements which are subsequently proved wrong But in this case, I think you are correct and we will probably use the spring type of mount. As stated before, we do have a set of those mounts here, but don't have the springs or special bolts to go with them. Can anyone provide a photo of them?
Cheers,
Andrew

Andrew, you can probably scale the bolts from Phill's drawing. The springs are primarily there to allow the "rigid" engine assy. to move away from the chassis, which will flex in a cross country situation. The spring specs are probably not that critical.

Hi Lynn

There is a problem with the perfectly logical of working back from the parts sheet number to the Canadian Parts Book part numbers. The Parts Sheet was US and for some very strange reason not all the part numbers back and forth across the boarder are the same.

I have both master parts books covering period of the pages I posted, both Canadian and US an it often drives me crazy to find visually identical parts one Canadian one US with two different part numbers.

The best use of either parts book these days is to find those parts which were common to a particular time to a particular vehicle and then go looking for parts that way.

Just to add to the fun the Chevy CMP Part numbers sometimes match the civilian parts book sometimes they don't.

As I have not installed the engine mount I posted pictures of I can easily provide dimensions.

Cheers Phil

G'day Andrew

I have posted two photos of the right and left engine mounts from an original ex NZ LRDG Chev. This Chev is in an unmolested state and I believe the engine mounts are the originals. Although the mounts are covered in grease and oil, you should get an idea of the set-up.

This is the vehicle the photos come from.





Engine mounts.





I hope this helps.

Bingo!
