David Schweizer Posted March 2, 2009 Report Share Posted March 2, 2009 Right i love my engine(don't tell the wife she starting to look at me funny),It's a hrw 2 and i'm trying to find a age to it.The No i've got 'r 191hw2m18 hope this helps thanks Paddy yes Smudge it blows lovely smoke rings :lol: The HRW range was introduced in 1969, but I do not know how long they continued in production. I am sure that Tony Redlshaw at Braunston would know. He specialises in Vintage Engines and can supply many "difficult to find" parts. Link to comment Share on other sites More sharing options...
magnetman Posted March 2, 2009 Report Share Posted March 2, 2009 I've always been under the impression you add 1950 to the last two digits this page seems to confirm that: http://www.stationaryengine.org/lister_dating5.html but then it'd be a 1968 engine which goes against what David just posted Ah... Its an HW, not an HRW Link to comment Share on other sites More sharing options...
Chris-B Posted March 2, 2009 Report Share Posted March 2, 2009 (edited) The HRW2 range was produced by Lister from 1969 to 1987 The add 50 to the last two numbers is normally correct BUT it is not the same for all Listers due to prototyping end of run etc When I get 5 mins I will post a definitive list of Lister and Petter production years Chris Edited March 2, 2009 by Baldock Link to comment Share on other sites More sharing options...

The engine in the OP is in fact a Lister HW2 which built in 1968. And not an HRW2. At least according to the serial number... and the list of dates in the other thread seems to confirm that 1968 was a year during which HW2's were built but NOT HRW2's where's my cracked record pattern anorak gone?

Ok I read part of the OP not the serial number ( am trying to work as well) HW 1963-1970 as per the list Off to get the anorak cleaned C Link to comment Share on other sites More sharing options...
paddy r Posted March 2, 2009 Author Report Share Posted March 2, 2009 So how do i tell if its a HR or a HRW sorry to be a pain but the plate with the No was not on the engine but in a box. will soon have to buy a anorak paddy Link to comment Share on other sites More sharing options...
Chris-B Posted March 2, 2009 Report Share Posted March 2, 2009 So how do i tell if its a HR or a HRW sorry to be a pain but the plate with the No was not on the engine but in a box. will soon have to buy a anorak paddy Paddy the numbers off the fuel injection pumps ( Bryce) would be easiest and best , other wise the numbers cast into the cylinder head will also identity Chris Link to comment Share on other sites More sharing options...

The HR is an air cooled engine. (Pedant anorak off) Baldock will probably be able to advise of the how to tell the difference between an HW and an HRW in the event that the serial number is missing.

lazyboy Posted March 2, 2009 Report Share Posted March 2, 2009 Your original number 191HW2M18 donates that your engine was the 191st HW2 built to a M (marine specification).The build type 18 would give the engine assembly track fitters the list of parts required to build the engine as a marine specification. There should be some preceding numbers to the ones posted which will give you the exact year of build. Link to comment Share on other sites More sharing options...
Travis Posted March 2, 2009 Report Share Posted March 2, 2009 I thought you if added 50 to the last two numbers it gives the year of build. 18 plus 50 = 1968. Link to comment Share on other sites More sharing options...

paddy r Posted March 2, 2009 Author Report Share Posted March 2, 2009 Right looked on youtube at hr2 and hrw2 both look like mine but not the same ,air filter,water tank,side on wich alti is,all right but not dead right.Sitting at whilton untill the 13th then heading for Lincoln.Any one on the way got 5 mins to stick there head in the engine room is more than welcome.Thank you all for your help.this place and the folk's in it are BRILL. thanks again paddy Link to comment Share on other sites More sharing options...

Externally unless you really know what you are looking at you will not be able to tell, even I rely on pump numbers and so does Peter Thompson who has been working on Listers for more years than he will admit !!! You can always give Peter or I a ring during the day about it if you want to Chris Clicky Link to comment Share on other sites More sharing options...
