Bamford model Z4 Diesel engine

December 1, 2010

Bamford was a British manufacture of small industrial and farm engines, among other things, dating back to the 1870s. I am not sure if they are still around, but believe they may be but trading under a different name.

A customer who has used our services before sent a scan of a head gasket for one of Bamford’s model Z4 diesel engines from the 1930s. He liked our price and decided to order four of them. Because the head gasket was too large to fit entirely within a scanner frame the customer split it in two, and with the aid of some supplementary dimensions we were able to reconstruct that and create a pattern. Upon receiving the gaskets this is what the customer had to say:

The gasket looks great as I expected it would.
Pleasure to again be able to do business with you.

I will paste an image of the scan used to make a pattern, followed by an image of one of the gaskets we made, and a picture of a Z4 engine:

Listeroid Gaskets

February 28, 2010

Earlier this month I wrote about Lister and Listeroid gaskets. Lister is an old English firm that manufactured a line of diesel engines that are popular around the world to this day, so popular that they continue to be manufactured in India by many different firms. These Indian copies are referred to as ‘Listeroids’ by the Lister engine communityto differentiate them from the genuine Lister engines.  Many are identical or almost identical to the originals, but the cylinder head pattern is one important area of difference. Lister OEM pattern head gaskets will fit many Listeroids, but there will be redundant bolt holes and the water passages do not match up 100%.

From what I have been able to gather, the Indian manufacturers have a habit of leaving swarf in the castings and the engines must be cleaned up and rebuilt in order for them to last. They also come with very poor quality gaskets, which is why many Lister owners came to us for help. At our Lister gasket web site we supply a head gasket for Lister and Listeroids that has been very well received by Lister owners, and we will be soon adding Listeroid patterns to our list of gaskets on the site. I will post a picture of one of these below along with the Lister pattern so you can see the difference. As always, we can customize both patterns with different bore sizes.

Stover DV2

February 28, 2010

Stover was one of the larger American industrial engine manufacturers. If my research is correct they were in business from 1895 to 1942. Shutting down in 1942 seems  curious, what with war-time production at capacity. I wonder why Stover wasn’t busy with government contracts to make engines or any other needed material? Perhaps a reader can enlighten us as to why that was the case?

The customer sent a scan for this gasket, and asked for copper sandwich construction. The backing grid indicated that it was not printing out at 1:1, so I foolishly adjusted it so that it would print out correctly. What I didn’t know was that the customer (without realizing it) had scanned it at less than full size, so the result was that I sent him a pile of gaskets that were the wrong size! We sorted that out, but just to be safe the customer sent the old gasket to us and we redid the batch.  I have since revised the scanning instructions at to make things clearer.
