Engineer museum

[MKTEF]

Hey guy's.

Today i got very good news

One of my fellows at work showed up in the door today:
The museum is dying on roots in the old engineer camp. The local club of retired officers can't afford to pay rent for the houses where the museum artifacts is stored.
And they are passing away one by one.

So we are supposed to take care of it and store it under a roof in our camp.
Well, i have some free space but not so much, our new machinery takes up a lot of space.
(always a smal problem with good news)

So later today i got a list of the machinery that will be moved to our camp already next week.
We are talking about Cat D4, D7, Cat 922, Broyt X2, wayne crane, M624, Willys, Dodge 3/4t, Magirus tank mover, Diamond recovery vehicle, diamond compressor and a lot of equipment i don't remember the names of right now.
We are now talking about things made in 1940-1970.

And everyting is restored and operationable.....:woohoo
Plan is to build some displays outside our Engineer training center.
Concrete areas with a roof over, maybe some spot lights too.
I'll post a lot of pictures as it arrives over the weekend.

Here it is Wrenchbender!

First some pics of our D7.
Not sure of the modell, bet some of u guys can tell imediately.
I looked at the plate, but it got a seriously thick paint so the numbers where not readable. Beliewe it is prodused within 40-45. It got a added English winch.
We where not allowed to start it. Theese babies is not nice to get started. The trick i have learned is to use fresh fuel, don't hold your fingers crossed around the cranking lever and use some time on it. I have seen guy's been trown over the engine hood and on to the tracks on the opposite side.

Last picture is of a ROC 601 drilling rigg for 3-5" holes.
When i joined the Army we used this one. U don't talk about oil leaks before its pouring out. This baby is constantly dripping oil.

Both of them is in working condition. The rig got a brand new drilling head...

Got theese two this week. And some more that i haven't got time to picture yet. I'll work on it on monday.

That old 7 looks good even in combat attire. It's kinda shame they wont let ya start'em up.:drinkup

 

[MKTEF]

You know wrenchbender, this one got rubber clutches, just pull both and get som towing help. Release both, and voilla.(Not nice to the rubber pullies though )
A beautifull noice from theese oldies, u know more like an old steamengine.
A slow rewing, soft, puff puff sound.

The Roc is in working condition, just crank up the compressor and drive on.
A noisy one though, everything is airdriven on this one.

Maybee i have to start them up next week and drive them indoors to get off all the snow.
They where parked outside last week, and it was snowing one foot yesterday.
Bad judgement by me, theese oldies deserve a roof in the wintertime.:Banghead
I got space for them, but they where delivered by the logistic guy's late at night.

More museum artifacts

I was on a trip down to our closed down engineer regiment camp at Hønefoss yesterday.
Some of our museum stuff is still there.
The retired officers club is still alive and kicking, so they keep some of our old stuff alive.
Here is some pics of it.
I'll post more next week....

Lets start with the wayne crane...

 

[MKTEF]

Wayne crane part 2

More of it

And its complete as a crane, drag line, excavator both forward and backwards.
Also got a ramming device.

 

[MKTEF]

More old stuff

Next objects:
Austin Western modell 99 A, grader, 4wd and 4ws.
Brøyt X2 excavator.
Allis Chalmers HD9B with snowplow and blade.
I'll get bether pics next week...

 

[MKTEF]

Still got some more:
- Controlls on the ALLIS.
- The Cat 922 with winch.

Remember having my ass in a Cat like that in the late 80's.
Good that the bucket is dimensioned to the force and size of the loader...

 

[MKTEF]

Here is some nice ones:
International TD 15
Cat D7, Pasific ocean, we call it.

Had my dozer education on the TD15.
The D7 is a WW2 modell.

Any details u want pics of?

 

[woodchuck2]

Those pics are great, thanks.

 

[Freightrain]

Really neat stuff!
Thanks for the pictures.

 

[Buckethead]

Anybody who saves old machines from the "bluetipped adjustable wrench" is alright with me! MKTEF if you ever come here, the beer is on me:drinkup

 

[MKTEF]

Thanks guy's

We have a smal plan for a project where some of theese babies will be put on a concrete slab with a steel roof over.
In front of the main Engineer building here in camp.

I'll have to do some project planning, and get my 3 apprentice operators to do some important work...

That D7.

Hi, MKTEF.
You have a good collection there. Thanks for sharing. I can remember the old Gardner Denver and Ingersoll Rand drill rigs of similar style. I even had to clean off quite a few areas ready for them to drill but always managed to stay away from operating them. Whew!

That D7 is probably either a 3T, 4T or 6T series - the 4T and 6T were the U.S. military versions with slightly different gearing and other minor differences. The 17A series which followed these models had mostly disk front idlers instead of spoked.

Thanks again for sharing.

Hey Deas..
As a expert on theese old irons, can u share some info with us?

The first one is a 1951 modell by the signs.
The last one is a 39-45 modell.(i didnt get a good pic of the sign)
(both is US army modells according to the signs)
I see the winch system is different, one has it at the front, the other at the back.

Is the designdifference due to age?
Or manufacturer?

Do somebody know if its possible to get new drive belts for theese babies?
If i am not wrong the oldest one has its drive belts broken...

On my first ride on theese old ones we towed some of them to get them started.
We used the poni engine on a D4, then we towed the D7's and just released both clutches.....
(and i know the tricks of starting the D7 with the poni, not that young....)

Expert on these oldies? Just how old do you think I am?

Hi, MKTEF.
The blade control winch location is due to design, timing and the particular manufacturer as well as the purpose for which the machine was to be used.

The front-mounted cable control on the later machine is a Caterpillar product. Cat used mostly LeTourneau attachments on their machines until the two companies went their separate ways in about 1945-6. Then Cat started making its own attachments instead of using LeTourneau's products. The split came about because LeTourneau started making 2-wheeled prime movers for its scrapers after having asked Cat to make them and being knocked back.

Cat started making front-mounted cable controls for the blades in order to leave the rear PTO free for other uses, such as logging winches or rear-mounted DDCCU's. The other BIG plus of the front-mounted units was that they were full-time live drive, not dependent on the master clutch being engaged.

The LeTourneau cable control on the earlier machine in the last photos is missing the top sheave arrangement that spooled cable onto and away from the winch drum. See the attached photo. This earlier machine would probably be a 7M series, given that build date range of 1939-45.

I'm guessing that you are talking about the fan drive belts. I doubt that Cat make them any more but I could just as easily be wrong about this. I'm also pretty sure that they would use the same belts on both machines so some cross-matching with other Vee Belt manufacturers might be in order.

You can also use the master clutch when pull starting these jiggers but using the steering clutches has the distinct advantage of making the towing machine pull less weight until it gets the towed machine rolling and you engage the clutches.

Hope this helps.

Nice!

Thanks for the pics of these old wonders. It always makes me glad to see older stuff taken care of. Deas if I remember correctly from somewhere wasn't there a marriage amongst Letourneu (spelling?) and Cat somewhere? It may have been someone else but I think it was someone pretty well thought of by Cat anyay :beatsme .

 

[MKTEF]

Thanks very much for the info Deas.:notworthy

We used the stearing clutches for towstart...

But your answers brought up a new question:
You see, i have not had my fingers under and into the technical solutions on theese Cats, so i rely on what i have been told.
(They are so old, we didn't get any education on theese when i joined)
Looks like i have to do some research and "higher" maintenance on theese babies.

I have been told there is rubber belts for the stearing clutches.
Is that right?
Or have they dry cluches with brake lining/pads as on a normal clutch?
If so, i bet there is some hours to do a rebuild of those linings.....

Rubber Belts?????????????????????

Hi, MKTEF.
I have been deep into the bowels of several Cat steering clutch compartments and have yet to see any BELTS. Lotsa clutch plates, brakes, springs, bearings, yokes, actuating levers and rods and a few other miscellaneaous items but NO belts. Except the ones I've used to lift the clutch packs out after I've unbolted them. LOL. I think somebody was either having a go at you or just plain didn't know themselves. Or maybe they were 'fullavit'.

The steering clutches in most Cats from very early on were first dry multi-plate and then wet multi-plate clutch packs with brake bands acting on the outside of surface of each clutch case on the output side, the side connected to the final drive. This is a large part of the reason why Cat crawler brakes (before power-assisted) are so effective - the braking effort is multiplied many times by the reduction gearing in the final drives.

You can get a bit of an idea of what's in there by taking off the inspection cover on each side and having a good old-fashioned LOOK inside. You won't be able to see the clutch plates - unless there has been a MAJOR explosion in there - but you will be able to see the brake bands and drums and also part of the actuating yoke towards the center of the machine. You will also be able to see the brake adjusting mechanism.

If my memory serves me right, these covers are partly under the fuel tank on top of the steering clutch compartment on each side. Some machines had these covers on the back face of the steering clutch compartment on each side but these were mainly smaller machines.

Hi, Bear.
There was a marketing arrangement between Cat and LeTourneau for many years. LeTourneau products and spares were sold by and through Cat dealerships until about the end of WW2. This worked very well 'cos Letourneau was the most commonly-used supplier of attachments for Cat crawlers. Blades, rooters, cable control units, drawn scrapers (pans), etc..
It worked well for LeTourneau 'cos they didn't need their own sales/service network and it worked for Cat 'cos they had the LeTourneau attachments for their crawlers right under their own roof.

To the best of my knowledge, this was the only arrangement/'marriage' between them. LeTourneau even built his first Peoria factory right opposite Cat's factory so that crawlers could be moved from Cat's factory over to LeTourneau's factory to be fitted with attachments before delivery.

Hope this helps.
