Engine identification SR2 or LR2 or LD2 or SL2
Chris_DK:
Greetings from rural Denmark and thanks for letting me join in. This is my first post and I am new to Listers and diesels. I have for some time thought about making a homebrewed genset for my homestead and before I long had five aircooled Listers sitting in my barn.
Two of them I think are SR2’s. One of them has no engine ID plate and the other has a rather odd plate, indicating that it may have been produced under licence at a Portuguese producer, but no numbers to indicate model or build year. One of them came with a lister gear
I hope you guys can give me a hint as to which design details reveal the true model and year of these two engines.
Engine 1(my guess is SR2)
Fixed rpm
Cast in crank case: 202 50012
CW rotation
It has inlet cold start cups
Says “Lister Diesel” on rocker covers
Engine ID plate says:
“Metalurgica Duarte Ferreira
AV. Dom Carlos (21??)
Lisboa Portugal”
As far as I can see Metalurgica Duarte Ferreira was a Portuguese farm equipment manufacturer that employed 800 workers at its peak. The company existed from about 1900 to 1984.
Engine 2(my guess is SR2M)
Variable throttle and mounted with Lister gearbox with forward and reverse
Cast in crank case: 202 50012
It has inlet cold start cups
CW rotation
Says “Lister Dursley England” on rocker covers
Thanks

Marine SR2 as far as I can see. We don't often see the old SRs in clockwise rotation in North America. The raised starter motor is an odd modification, first one I have seen done like that.

Thanks.
I removed the electric starter and the gearbox and handcranked it to life, but definitely not an easy starter, but ran ok on both cylinders once it was running.
Do you have any comment on the one with the portuguese engine ID?
sirpedrosa:
Hi Chris
Yes Metalurgica Duarte Ferreira was a Portuguese farm equipment manufacturer, colonial war army trucks and other machinery and a Lister importer from England, for PT market.
Just scratch the paint around and you will find ID plate.
Usualy "marineized" engines are engines that are originaly air cooled and modified to water cooled.

Hi Chris and welcome to the Forum the numbers you have posted of 202 50012 would only be a casting number for that component and not the engine number which is what will be needed to date the engines.
As sirpedrosa has posted there should be a id plate ivetted to the engine block and most likely near the fuel pump. If you do find this then be very careful in removing any paint from the plate. The numbers will be stamped into the plate but the writing telling you the details will be painted in black paint usually. Details on the plate will tell you engine number, model, hp and RPM. Engine number is what is required to date the engine/s.
