New Ruston & Hornsby Hopper cast.
9th May 2008
We have a few Ruston & Hornsby PT's in South Africa but they are mostly "tank cooled" versions. For shows (Rallies) we prefer hopper cooled engines as they need less water carried (often with a bucket from quite a distance away from the engine display area) and they take up less space on the back of a "bakkie" (truck/ute/pickup) allowing us to take more engines to a show.
I have a tank cooled model <Here> and

in Natal who had a spare magneto and gear but needed a hopper. A deal was

model. We removed the hopper and cut it in half (with an extreme amount of

our "friendly local casting plant" who produced the new hopper shown in the
Converting the Ruston PT to a
"hopper cooled" engine is very easy as it only involves taking the 6 fastening
bolts out and removing the "top water jacket cover" from the tank cooled
engine and bolting the new hopper in place. The cylinder head remains in
place unlike the Rustons successor the Wolseley WD range which had the cylinder
head and hopper incorporated into one casting.
Here are a few pics of the raw casting as we got it back from the casting shop today.
