MARS 5HP DIESEL ENGINE - 1st Start Up in 50 Years!
Watch as an early 1940's MARS Diesel engine is fired up after 50 years.
Originally acquired from a cane farmer in Nambour, Queensland, Australia in
the 1970's, this engine sat in careful custody with another three owners
before finally retiring with me.
MARS engines were made by the MARS Machine Tool Manufacturing Company in
Brisbane, Australia and were preceded by the horizontal and vertical Rapson
and Dutton engine, made by the same company under the Rapson and Dutton
MARS engines are not Lister clones. Mars engines are bigger, heavier and
more robust than Lister engines. When you listen to a Lister and then to a
MARS you will agree. This engine has a 3 " diameter crankshaft and not one
component is interchangeable with a Lister.
MARS engines were commonly used in industrial situations such as factories
to power line shafts which powered a number of machines, a task Lister
engines had some trouble with apparently with their crankshafts twisting
under the load on start up, and why this company made the Mars Diesel.
5 HP MARS engines were painted Maroon colour as standard from the factory
although there are variations of colour in existence. 8 HP engines were a
This engine has not run since the original owner sold it in the early
1970's. Apparently it had not run for some years before that. The second
owner sadly passed away before restoring it and it sat in a shed untouched
with the third owner.
Close friend and temporary fourth owner, Simon Devere, assisted actively in
the mechanical restoration when I purchased it and assisted in the first
start after its mechanical restoration. This man is a genius when it comes
to diesel engines and he has the nickname "The Lister Whisperer" for good
reason. Thanks "Slippery".
This engine appears to have not done much work judging by its internals.
Work to the engine includes new rings, liner/cylinder hone (the original
factory liner had indiscernible wear in it), new valve guides made to
original specs, new valves to original specs (original was bent and caused
damage to the guide) , new big end Babbit bearing, new conrod bush, very
light head machine to ensure true flatness, new internal oil pipes, new
head gasket, new oil gaskets, new high pressure line, new welch plugs in
the head and new oil pickup.
There are still remnants of the original factory maroon paint on it that
have survived the years of weathering out in the cane fields.
Cosmetic restoration is planned shortly to bring it back to its original
livery. It will be mated with a steel transporter to emphasise its
industrial heritage and will be rallied with pride.
Video of the finished engine on transporter will be posted when it is done.
Enjoy and please share if you like.
This is the only video of a Mars engine running to this date anywhere. Hope
to see more.
