Yes, it's a 1950-52 Jobmaster Six 235 Truck engine. Have you got the casting date code please? We can then identify which year it is. I can then add a new prefix to my database collection!

Hi All

I need my memory updated, was 1950-52 Jobmaster Six 235 Truck engine a dipper or a pressure lube crank? Next question did they make the change from dipper to pressure crank at the same time in US and Canada?

Pretty sure that it is a bypass filter system but is it like the later 235s that can be converted to full flow filter system.

Cheers Phil

The weatherman was calling for the building of arks. Fortunately for the Ottawa area, the storm front split east and west of us, drenching Montreal and keeping Kingston damp.

Bob, Grant and I took advantage of the fair weather to further our projects. Bob continued work on the world's strongest rolling engine stand. Grant pulled his transfer case to check it out, and I played with the prototype HUP.

While all of this was going on, we were surprised to see Clive standing by. The aim of his surprise visit was to put some of his rolling stock to bed for the winter. After sorting out his shelter, it was loaded up and sealed enough to keep the coming snow outside. Clive then showed off some his recent publications (see more at: http://www.servicepub.com/) including one on the Churchill tank. This got Bob's attention as earlier on in his youth, Bob was instrumental in saving one of two Churchill bridge layers, one of which is on display at the Canadian War Museum. We all donned our helmets and listened to a "war story" that should be written down sometime in the future.

Following Clive's departure, we all got back at what we do best - pulling things apart and rebuilding them (sometimes more than a few times). I removed the sliding hatch guide rails from the prototype roof. It turns out that roof is in rougher shape than I had originally thought. The leading edge of the roof, most of where the rain gutter meets the roof line and all of the areas under the sliding hatches guide rails will have to be replaced.

Bob suggested that the front edge metal of the roof should be replaced with a better version from one of the many roofs we have at the barn. The discussion turned to where to cut and the best area to reweld. When it came time to compare the roof lines it was discovered that the production model HUP roof leading edge was stamped, whereas the prototype roof was hand formed and welded. The profiles are quite different - the production model is rounded and somewhat taller. The prototype roof leading edge is flatter, and has a visible sharp line where the roof metal was cut and welded.

A new plan was devised. I will save as much of the original roof as possible and weld in patches where needed. Fortunately, the welded side ends of the leading edge of the roof are in good shape. Other areas were not so lucky - see follow on photos.
I know what I will be doing this winter.

Starting with Phil

Yes the "hat" section that reinforces the cab 11 runs left to right just ahead of the head pads......

Not sure exactly when the "splash" oiling ended on the 216 and 235...... maybe David can sort this one out........

David..... here are some numbers from the mystery engine

Starting form the top... on the dizzy side.... between 3rd and 4th cyl. are small 1/4 inch numbers.......22
909 ....... directly beneath the 22.

On the head....outside the valve cover..... near mid section near carburator

...........................3835909

inside the valve cover......GM 11 and C 16 4

............... which I translate to March 16 1954 or is it 44

Confirm serial no. Y 24340


Block.... below dizzy... behind draft tube..... 3692713
1 below the seven.

I could not find any similar Alpha numerical casting number on the block....?

I did find a large GM with a one inch circle and 1/2 inch square inside.


Phil..... I forgot to remove thelifter covewr to see if I could find another number...maybe that is where the casting date is.....

I poured acetone/ATF into the cyl. and the engine turns ....but only about 200 degrees..... then it is stuck....... we truned it back wards agains and turned it back to the stuck ocation again using the starter....

So there is hope....... is it a rust ridge in one cyl. or a broken rod with a piston lodged half way up a cylinder..... owner tell me engine ran when removed from the truck....... sounds like a winter project by the "lucifer" with the engine on a swivel engine stand.

Thanks everyone.

Hi Bob

As for not turning all the way through, don't force it it may be a valve stuck down and hitting the a piston. Check while you turn the engine over by hand to see if the valves are moving up and down on the cylinder that is coming up on stroke. I remove all the plugs when doing this and then use a piece of copper wire bent to slide down the spark plug hole to find which pistons are the highest up, then check the valves on those cylinders.

Cheers Phil

[Bob Carriere]

Hi Phil

I like the bent copper wire to see which piston is moving......

I had removed all the plugs to facilitate turning the engine and some fluid/lube did spill out when the engine partly turned over.

Before turning the engine over, I loosened up all the valves with light taps from a hammer.... then Grant manually depressed each valve with long screwdriver..... all valves moved and sprang back.....

I am afraid that nothing short of removing the head will give me a clear answer but will try the wire trick first.

Stay tuned.

After loading the truck and trailer on Thursday night, Bob, Grant and I headed to southern Ontario on Friday morning to recover a CMP. After traveling the equivalent of the breadth of the Province of Saskatchewan, we arrived at our destination near Godridge, Ontario. We pulled into Gord Yeo's farm a little after 5PM to load up a new (to us) CMP truck for Bob, and to drop off an engine for Gord. Gord's truck was the stable mate of the truck we picked up in Paris, Ontario a few years ago. Hopefully, Bob will chime in with that story later.

Prior to the loading of the truck, Gord gave us the nickel tour of the farm and his vehicle repair/restoration workshops. Along with the requisite finely restored CMP, Gord also had a deuce and a half (M35 series), a few jeeps and some Iltis trucks in various stages of restoration. We were impressed with the quality of work of these restorations.

After loading the CMP, Gord mentioned that he had some old Dodge M37 parts that were heading to the scrap yard. We saved him the trip and loaded every M37 part we could put onto the trailer. Gord was in a very giving mood and provided some additional CMP parts. I guess it was his way of doing a clean up, and we were more than willing to help.

By this time it was closing in on 7:30 PM. With the truck firmly knitted on the trailer, we headed for Guelph where we would stay overnight. On the way we spotted one of Bob’s favourite restaurants – Swiss Chalet. After carefully parking the truck and trailer, we enjoyed a good chicken dinner - Bob was particularly appreciative of the breasts. Then it was on to the hotel for a good night’s rest.

The next morning we checked the chains and headed down the road to Acton to take in the militaria show. No sooner than we had pulled into the parking lot, then a gent came up and asked Bob “How much for the truck?” Bob wasn’t really in the selling mood so it remained chained to the trailer. Inside we found the usual suspects flitting from table to table wheeling and dealing. There were some good deals to be found and after our newly purchased items were stashed away in the truck, we headed back to Ottawa.

Along the way we ran into some road construction and we experienced a few good sized bumps that shook the truck. This was nothing out the ordinary, so off we went down the 401 and then onto the 407 drag strip. Just short of Pickering, Bob could be seen peering out at the side mirror with a quizzical look on his face. When asked what was up, he mentioned that it looked like the second wheel on the drivers side of the trailer was protruding somewhat. Now this was odd, but we soon came to the end of the 407 and pulled in for some lunch. We checked the tires and noted that the rear tires on the trailer were warmer than the lead tires. We decided to eat first then get dirty checking tire pressure and tie downs.

After lunch, Bob in his usual understated way said “Uh-oh! We have a problem”. The rear axle of the trailer had been pushed back slightly on the passenger side causing both tires to run at an angle to the direction of travel. We determined that this situation was just a small problem now, but it could quickly turn into a major problem at highway speeds. There was no question that the trailer had to be repaired before we hit the highway, and Bob decided that it was best to find a place to park it until the repairs are completed. Safety first is more than just a sentiment with the Hammond Barn gang.

Fortunately, we were close to the world famous “Chicken Ranch”, so we decided to take a nice, slow, short trip up to the ranch. There we chatted with the land owner who gave us permission to park the truck and trailer until we could get back next week to repair the trailer. It is good to know so many people in the hobby; else we would have had a big problem on our hands. The Chicken Ranch was a welcomed solution to that problem.

With the trailer unloaded, we jumped back into Bob’s Ford and headed back to Ottawa. We pulled into the Hammond Barn at around 6:00 PM. This was a milestone recovery – the first trip where we failed to bring home a recovered CMP. Despite the inconveniences the trailer situation caused, we were happy with the trip. We are in this hobby for the enjoyment factor, and we do not want to be part of any unsafe activity that could impact others.

The happy ending will have to wait until next week.
