Metal Magnets's M211 teardown and future rebuild.

[USMC 00-08]

I would like to know exactly what kind of transmission and bell housing was used.

Transmission I.D.

To answer your question on transmission I.D. and bellhousing.....look here. I double checked to make certain I am right, and this is what was installed in place of the automatic. As for bellhousing, I believe it's a civilian truck bell from a 270 engine. Starter is unknown at this time. Hope this helps.

Great! Thank you!

This is a 1963 G.M.C. 270 engine which I suspect has the same bolt pattern, for the bellhousing or was altered to bolt on to the 302. The flywheel, and clutch was also likely used, but uncertain at this time. I will be working on getting this truck running as soon as possible, now that my boom truck is together.

The last GMC-only straight six was the 270-cubic-inch (4.4 L) 270. It was produced from 1941 through 1963, and was an OHV/pushrod engine. This is a raised-deck engine. The bore was 3.78125".

Is there a way to figure out what vehicles might have come with that engine?

M-135 hauling an Insley K-123(?) crane and other things coming home

https://youtu.be/AoWxtJiTTgc

 

[metal magnet 1963]

This is the latest truck I bought.

This is the one with the standard trans . It works good, but would work MUCH better with the original trans installed. I barely hauled the crane in first gear, where the other setup would have had no problem. I'll keep you posted on other stuff.

 

[USMC 00-08]

I'd like to see some more video of the standard transmission M135 in action so we can really get a good idea of the performance difference.

Asking you do drive the truck around more wouldn't be too much to ask would it. Haha!

 

[metal magnet 1963]

Transmission

Yes more videos to come. Don't take your auto trans out whatever you do!!!

 

[metal magnet 1963]

I had a chance to give the truck a run around the yard, and found it to suck big time when you got to 3rd gear. You lose far too much when you go to a standard setup. It really bogs down but on highway would likely go well, if you have no load or hills to worry about https://youtu.be/_Tzq8Tqh7a8

Flying Kitchen



This is a picture of a M135 equipped with a "flying Kitchen" used in the Canadian armed forces. My girlfriend worked in this type of setup when she served in the forces. The U.S. didn't go this way.
Just wanted to show how much snow has come down here.Believe it or not, there is a M-135 completely buried next to the old blue truck.(4x4) ......
It'll be awhile before I can even think of playing around with them, have another full schedule planned for this summer so time will be at the short end of the stick.

Awesome pics

We might want to talk about your girlfriend more in private messages because I have questions.

We're looking for the team that fed the troops throughout operation morninglight between 77' and 79'. Was she serving then? That was the operation to go up in northern Alberta and search for a downed Russian satellite.

We have access to parts of one flying kitchen that went on that mission and the thought of saving it is motivating. Did she snap any photos while working in the kitchen?

I'd love to hear about her service so when you're not looking, get her to call me or find some time for a screech sit-down and I'll phone you.

Good to see the snow magnet. Is that a normal amount of snow that would visit 30 years ago? Kinda takes your breath away. Not because it's beautiful but if this short fat guy fell off one of those trucks it looks deep enough to choke me. Be safe out there buddy and get on that drainage early.

 

[metal magnet 1963]

Hello plowboy, as for "normal" amount of snow, it's kinda average I would say. Seems like it snowed every second day. Made it miserable to do anything in the basement, because you have to clear the snow first, and that took all weekend to get back to normal. My girlfriend only entered into the services around 1980{boot camp) so the dates that you need info on are too early for her. She said she would help with what she can. She loved her job, but HATED driving the trucks. Who would have thought that manual steering would be a GREAT IDEA for those fully loaded trucks???? Seriously?????? She also was responsible for maintenance on the road,and had to back the trucks (with trailer) into position. She isn't tall, so she labored doing the driving, and said there was no heat either in the truck. That's another thing I can't get out of my mind, why in Canada, no HEATERS-POWER STEERING? That would seem to be a no brain-er to me. Stay in touch boy's, i'm so swamped with work that it's hard to find time to get on here.

 

[metal magnet 1963]

Plowboy, are you still around? Just saw ground under my m135 and soon will be moving things around here in a month when ground dries up. Drop a line if you can. Been so busy haven't touched the trucks in a long while.

 

[m1010plowboy]

The country is big and time is small

I haven't been around as much as I'd like so I found a round place closer to you. It's in Alsask Saskatchewan and we're going to book a few weekends this year for visits.
You still traveling with a troop? What's your mission with the trucks this year?




We're researching like mad men to dig up all the CD / EMO Civil Defence and Emergency Measures Organization stories. We're doing oral/ video interviews with veterans and really need everyone to chip in with their CD/EMO/ Military bio so we can save even more stories. Know anyone that drove a deuce that could cook up a mean story? lol.

This is one of the maps I put together and you're one of the first guys to see it. Each one of those yellow dots represents up to 3 radar domes like the one in the picture. Each site was a small city with all the essentials to support people from winter right through mosquito season. The work we went through back in the day so I could follow a yellow dot road right to your place is impressive. That yellow dot on the Sask/AB border near the 49th parallel is our dot. Think about a visit before we're too old to climb stairs.



Here's the map that the Canada War Museum started and is still a work in progress. I can see your house from here and it's just about time to mow your lawn buddy!

Thanks for the maps, depends on when picture was taken of my place. Couldn't see it on map, but will be awhile before lawn gets mowed here.
