HUGE LEYLAND 2 STROKE L60 ENGINE!

I have several Leyland L60 chieftain tank engines in unknown condition.
Me and Mr Best fire one of them up!
We need to find a suitable engine for "Concrete Chieftain"

[@geoffbuck6890]

As a Student Apprentice at Leyland Motors I’d walk out of Spurrier Works and hear the sound of L60s being developed in the Research Test Centre with a deep roar coming out of the exhaust stacks echoing around the factory buildings - wonderful… We were developing the multi-fuel capability of the engine which compromised the engine, then the bloody British Army said they didn’t want this. Based on the Junkers Juno engine concept, the L60 never made the performance of diesel tank engines from Rolls Royce despite performance packages such as “Sun Dance” (if my memory serves me) and it never achieved what it might. But it was a beautiful engine, and seeing them being produced on the assembly line painted in that glorious duck-egg blue which the army liked their engines (I think as it helped spotting oil leaks!) was a sight one would never forget. Before the British Government forced Leyland Motors to try to save BMC and all our funding was syphoned away slowly bleeding a proud and great British manufacturer to death…

[@dieselhatz4247]

Rumour was it was to prevent people stealing them as they were so obvious in colour.

[@thewomble1509]

The "bloody British Army" NEVER wanted the multi fuel capability, it was an edict passed by NATO that was subsequently ignored by all the major western tank producers with the exception of the UK Gov't who were determined to "play the game".

[@davidelliott5843]

The English Electric (Nee Napier) Deltic was developed from the Napier Culverin which was licence built Junkers Jumo 204. What a shame we never had micro deltics for heavy road vehicles and tanks.

As a technical manager for a pump manufacturer I went to Catterick camp some years back, a new test rig built for testing rebuilt L60 engines wouldn't cool correctly. We checked all the usual stuff and found the pump performance at 50%. Found the impeller half full / chocked with rubble from when they installed the suction tube into the wet well water sump. Pipe bell mouth was too close to the sump bottom which hadn't been cleaned properly before recomissioning and sucked all the debris into the impeller. Warranty declined - bill for our time..

[@davezipman8959]

If my old memory serves me well the 11a is a fully reliability and life improved engine with the same power output as the 13. Apart from a couple of minor sealing mods they are the same engine. That noise takes me back!

That must be about the same design as the old 2 stroke Detroits here in the US. They sound exactly the same. Had an old diesel mechanic tell me once that the old 2 stroke Detroits aren’t much for making power but they’re great for turning diesel fuel into noise.

One of the main failure points of the L60, was that Tankies wanting a brisk start would rev up and drive off before the oil had reached the top crank. Otherwise it was a very good engine if treated properly, but as we know, if you wanted to test the durability of anything, give it to a soldier! 😄

I'll remember to check the Engine when I go to buy a Chieftain. Great advice! When I served my apprenticeship i worked on U series Leylands and C range Roll Royces .Those scavenge blowers were a chore to overhaul.We had a big board on the wall with end plate gaskets of various thicknesses and if the blower lasted 3-4 minutes on initial start up,all was OK. a blower seizure wasn't unusual.

Gotta love a 2 stroke diesel. I hope that Leyland made them as good as Detroit. The only issue is the oily exhausts that tend to catch fire and become small flame throwers. Pretty cool unless you're standing in front of the exhaust when it ignites. The Napier deltics had a habit of it too.

As an ex Chieftain crewman I can say it’s one of the least reliable engines ever and were a nightmare. A pile of crap. The only good thing was Chietain could turn at tick over so good for track bashing and getting into a tight hangar or hide. We also had a length of green army cord running from the solenoid through and under the turret floor into the cab so the driver could avoid having to open the back decks to hold it open after overheating. Everything on Chieftain is a massive fcuk around and the sprocket bolts shake out after a days motoring. I don’t miss replacing them in the mud and German rain using just a torch and hylomar gel to hold them in.
