Tractor Cab Glass

I have a 1976 Case David Brown tractor with a Prairie Cab. Can anyone tell me what kind of glass the cab was manufactured with? Plate glass or safety glass?

Also, I need to know how to repair the power steering pump. It seems a seal has gone.
 
Regardless of what it was use safety glass, just not worth the risk. Any glass shop likely stocks more laminated safety glass flat stock than any other type of glass. In my experience the cost is the same, and you can handle it much rougher to install it than float plate.
 
I agree with Doug. I don't think my local glass shop guy would cut me anything other than safety glass. He offers, and I get tinted, to help a little on keeping the heat down.
 
Definitely safety glass, either
laminated or tempered. Plate glass
would create a real hazard. New
machines typically have tempered glass
at least on the sides so the operator
can break out in an emergency egress
situation if the door is blocked.
 
Bob, local glass shop can only cut laminated glass. Tempered/saftey glass can not be cut after it has been tempered. When I built the cab for my 440 a couple years back, I had a good supply of salvaged glass from tractor cabs, and I also had a couple of windshields out of trucks. The only ones they could recut were the laminated truck windshields, however I built the cab to fit some of the salvaged tractor cab glass.

I'm probably not using/don't know the correct terminology. Wouldn't the used truck windshield be considered "safety", in other words, break into hundreds of little chunks, instead of big, sharp, shards? I think that's the type my guy cuts for me.

How's all the glass for the 931 cab?
 
A glass shop can make laminated or tempered glass, cut to size, as long as it's flat.

The difference, laminated is 2 pieces of standard glass laminated together over a plastic film. If broken it tries to remain in place, the plastic contains the shards. Typically used for front windshields.

Tempered glass is very strong, but can be broken. When broken it shatters into gravel size chunks, no shards.

Another solution would be Lexan, or poly carbonate plastic. Think "bullet proof glass". It would work for lesser windows, something not critical for clear vision. It can be cut with a saw, is unbreakable, but is not optically desirable, scratches easily, and will sun craze.
 

In an old brochure I have from Prairie Cab Ltd. in Winkler, Manitoba (late 1970's), they advertise a choice of tinted glass or laminated glass. Not sure why you couldn't have both? The Prairie Cab I had on my combine was tinted.

Can you make a copy of that brochure for me?

Tinted and laminated are not the same as safety or tempered glass. I'm well aware that a tractor cab should have safety or tempered glass. The cab I have is all plate glass and it looks OEM.

I need solid proof that Prairie cab used plate glass in its installations. Any help in this regard is greatly appreciated.

The tempered glass has to be ordered by the glass shop. The supplier cuts the glass and then tempers it. Any good real auto glass shop can cut and install laminated glass in your choice of clear, tinted, and in some cases shaded and supply the gasket material.

I found another brochure after posting last night with more detail. It says they used sheet glass.

No,, Laminated glass cracks but doesn't shatter into tiny peices. The plastic laminates on the surfaces hold it together. You can cut the plastic laminat on each side and then snap the glass just like plate glass.
Google " cutting laminated glass"

Last year I needed a window for a snow cat. The shop had me take the other one out for them to get it duplicated from their supplier. it was around $175.00

This is awesome. Just what I need. Any more?

Where does it say they used sheet glass? I need to see this statement clearly in the brochure. A confirmed date for the brochure would also help a lot.
 
The reference to sheet glass is on page 1 - History of Prairie Cab with the girl looking out from the cab. 8th paragraph down.

There's no specific date but I picked up this brochure before I bought my combine cab from them in 1978. The other brochure was the one I referenced in my first post, it doesn't mention sheet or safety glass, only tinted or laminate.

I noted in a brochure for Fibro Cabs (made in Sask) from the same era, they mention using safety glass. We had both cabs, the Prairie Cab was, in my estimation, the superior cab.
 
If a 4 cylinder tractor, PS pump is pretty easy. 2 bolts hold it to the timing housing. Comes apart easy once off, just mark the pieces with a scribe line down the side to make reassembly easier.

Case sells the seal kit, for $50ish, Sparex sells them for under $10. Neither ever seems to have all the orings so I order 2, and have parts left over.


If a 3 cylinder tractor, seals and pumps can be harder to come by.
