I am rebuilding a 1931 north sea trawler that was originally fitted with a two cylinder Bolinder. The variable pitch prop , shaft , pitch ajustment gear , thrust bearing and cast iron bedplate were still in the hull when we got it. The hull is 18 meters long , 6 meters wide and draws 3 meters. We would like to identify which model Bolinder we are looking for and then find one to fit to the engine beds.Can anyone help?
I assume you are referring to a Bolinder semi diesel, rather than the later full diesel versions. There are a number of 9hp and 15 hp singles in narrowboats, and I think a 30hp in the tug Worcester(?) at the Boat Museum at Ellesmere Port.
The only twin cylinder Bolinder semidiesel I know of is in the Waterways Museum at Stoke Bruerne. Originally fitted in a tug which was acquired by the Grand Union Canal Company, the engine was subsequently installed in the backpumping station at Knowle Locks. It was run for the first time in years during the drought of 1976 and could be heard from some considerable distance away. Such was the success of the backpumping that the engine was replaced with an electric motor and the engine ended up at Stoke Bruerne.
For more help you could try asking on uk.rec.waterways or
Also, some Bolinder manuals are available from
which may help with identification.
Keep us posted on this project. I would love to hear more about it. Where are you based?
There are the early 'large' singles and twins, then there was the later W series engines which were much smaller but more efficient.
Pictures of the W engine we collected from Alicante last year are in the trip reports, and some of the larger engines are shown in the marine diesels section of our web pages.
There are a couple of guys who watch this newsgroup, one of whom has an early engine, and his next door neighbour also had one. That may be out of date now but was good info around the time we went to Spain.
