Well a new "BIG" problem. The engine I have doesn't fit in my car. The motor mounts on the engine do not spread wide enough to align with the motor mounts on the frame. The engine # is 836915 J 25 2. Looking up numbers in the parts book shows that number for 29 to 31. What do the experts think? It's like the parts are made for a narrower frame. As I remember the earlier frames were straight ladder frames.
Any ideas?
Thanks Don

The engine 836915, is a 1933 truck engine.
What year/style are you installing it into?
Front or side mounts?

My car is 33 5 window coupe Master.

Is the 33 truck a ladder frame?
My 33 has front, two side, and a transmission mount.

Hi Don,

Hopefully some one will have the solution for you.

Did your car come with the engine out?

Or did you purchase another?

Cheers

The engine was with the car. However it was in a box and not in the car. I'm pretty sure I can make some motor mount adapters. At least it's the same year engine. I'm currently checking the transmission etc. alignment. I'll be putting some pictures on my blog tonight so all can see the difference.

What do they say

Good luck, I will keep an eye on your Blog.

Well the good news is, after much "shoe honing", The truck engine fits. The motor mounts still are short of their correct position. I'm wondering if the mounts are for the standard car. Does anyone know if there is a difference. Can anyone explain the difference between the truck vs. car engine. In more modern engines the truck usually has a longer stroke with more torque and less RPM. I like to know the specs if there are any available.

Beauty Don,



Well done. Now you can truck on down the road. Dont know much about the difference but would think like you that they dont rev as fast but have more low range grunt.

Bet you cany wait tro find out.

Cheers

You can look at the blog to see how the side mounts don't line up.

Good photos Don.

Interesting development. Other will know better than I, but it could be as simple as changing the mounts, or at worst a bit of fabricating. One side looks like it just needs a bit of packing to bring it out, dont know about the other.

Your 33 is leaps ahead in technology to our poor Chev fours, with some details designed back in the early 20's.

Good luck, I know you will get there.

Cheers

Don,
I'm not sure if I am reading my '29-'39 parts book correctly but if I am the "33 CA car block and the '33 CB pickup block are the same but the engine side mount brackets are different. Hopefully Chevgene or one of the other experts will comment again.

The CB block is the same as CA except the CB block is not drilled for bolts in the flat area on the side.

The front motor mount fits under the cross member, not on top.

The 1933 Master mount is under the cross member as stated. The studs on the front mounting plate go through the mount - then the holes on the ends of the mount bolt to the cross member.

That mount was used on 1932 and 1933 cars and also used on trucks up to the 1954. The mounts were improved over the years and are still available.

The side mounts require brackets. On the right side a short bracket bolts to the bell housing, The bottom of the mount bolts to a short bracket on the brame.
On the left side there is a large long bracket. It has four holes where it attaches to the side of the engine. A boss cast into the engine (under #4 cylinder barrel) has four hales with studs for mounting the bracket. No if this engine was from a truck the boss may not have the holes or if it does have they holes they may not be threaded, This long bracket reaches over to the frame, the mount is attached to it and the mount sits ona a frame bracket.

There are good pictures of the mounts and hundreds of other parts in the 1933 Engineering Feature manual. It is available from ....www.fillingstation.....for a very reasonable price. I would suggest you invest in ti as well as the 1833 shop manual that they also offer at a reasonable price.

I looked behind the fuel pump and found the engine number.
374543 Can anyone tell me what year etc. thanks. The number I gave before as someone mentioned was the block number.

If your engine is supposed to be for a 1933 Master, then you are missing one digit in the serial number since it should be a seven digit serial number, not a six digit serial number.

The engine serial numbers for the 1933 Master ran from 3367317 to 3964077.

3 374543 seven digits.
Thanks Don

Chev Nut, your description of the motor mounts for the 33 is right on. However if you look at the pictures of the side motor mounts in my car you will see that the side mounts do not reach far enough to connect to the rubber mounts that are attached to the frame. What I'm wondering is that my mounts are for a Standard model. Everything about the standard model is smaller. My question is are Standard and Master mounts a different size. And I have the wrong ones. Do you have any thought on this?
Thanks Don

The bracket you have looks just like the 1933 Master bracket picturedmin the 1934 parts book. They do not list a bracket for a Standard and I do not have a picture of one if there is one.
If the engine is from a Standard the water pump will mount to the head - the Master mounts to the block.
Perhaps some one here with a 1933 or 1934 Standard can check their left mount bracket.

I found a picture of the left side of the 1933 Standard engine and it does not use the mount bracket.

Maybe the problem is the after market rubber motor mounts I bought.

Your problem is in the motor mounts. They are for a 34.
I had this same problem and had my originals re-vulcanized. Installed them and they fit perfect.The 33 mounts are round in shape.
Thanks,
James

Don - I also have aftermarket rubber mounts and they fit perfectly. There is an angle to them, so they don't line up directly over the holes in the slanted frame braces.

Roger

I finally got thing to line up fairly well. I will be including pictures and explanation soon. The engine and transmission have been re-installed. In testing the clutch I found that the adjustments had to go to the limits. In inspecting all the parts, it's apparent that I have accumulated areas of small wear. So I will be taking the linkage apart and overhauling all the parts. Pictures etc. will be on my blog. So now I'm open for all comments "clutch".
Thanks Don

Roger, I've got them to work also. It looks like I will have to replace the front mount however. I mounted it under the frame to get the side mounts to fit. Is your mounted under the frame?. How much clearance do you have between the front mount"steal" and the frame itself?
Thanks Don
