Title: Early JP2 loco engine
Post by: Seedyh on March 10, 2017, 12:27:39 PM

Any info please on an early (1931?) JP2 engine.  The cylinder heads are machined with an annular ring which locates over the liner rim.
They are sealed with plain copper rings and shims to adjust bumping clearance.  Water jacket sealed with rubber gromets.
Will the bumping clearance be the same as for later flat head types?
This engine is fitted into a Ruston narrowgauge loco but is definately Lister and not Ruston.
Any info would be welcome!

I'd really like to see some pictures of that! To do that here you'll need to host them somewhere and link them to from here.

The JP series stands for (joint production ) which was with Ruston hornsby. Ruston made the larger castings like block crank heads rods pistons, and lister made/fitted the rest. There neat engines i had a jp3 for a few months but it was massive.  Ran good but smoked a little.
