WOW, how did you pick all this up on that one crappy photo? I'll have to blow it up and take a second look.
That's exactly what I did
, but due to the picture quality eBay size restrictions place on listing photographs, there is a limit to how much enlargement can take place before the image becomes too pixilated.
I found them to be troublesome and awkward to build.
Could you possibly expand on that please.
I can think of several areas the KHD F2L engine is an improvement on a comaparable sized Lister ST engine, such as: only one fuel pump to spill time, use of Bosch fuel injection equipment verses Bryce (which is not well known outside the UK, and hence could be more expensive to repair), external fuel injection equipment (hence no engine oil dilution from diesel leaks), gear driven oil pump verses Lister's plunger pump, induction hardened crankshaft journals, electric starting as standard, available as indirect or direct injection, one piece cylinder head, on multi cylinder engines conventional centre main bearing caps instead of main bearing cheeses which can and do fret in the corresponding crankcase bore, oil is filtered for all bearing surfaces (unlike the ST engine where timing gear main bearing (ST1 only) and rocker arm bushes are supplied with unfiltered oil.
In addition the KHD engine was a new design whereas a comparable engine, the Lister ST range was based on the Lister LD engine (a 1950's design) which Lister's had stretched to the limit of its bore and stoke capacity with the ST range, but still using the same crackcase casting as the LD range. Which made assembly of the crankshaft balance weights only possible when the crank is partially assembled into the crankcase. Combined with Aluminium lower half cylinder heads (when previously cast iron was used on the smaller capacity engines) which were known to crack if the injector clamp bridge piece holding down bolts are over tightened.
However I would conceed that the KHD engine is a considerably more complex engine than the Lister equivalent, and will deteriorate faster than a comparable Lister engine if not maintained as per the manufacturers recommendations. Which would be more likely to occur on an engine working for long periods of time un-attended in remote areas such as an Alaskan oil pipeline.
