Allan Mercury 3,5 diesel
Circa 1960
 A nice find complete with original box and papers

 Unfortunate the big end is worn out and needs a new rod and bushing


Design History:-
Designed and manufactured in England in the late 1950's


Design Features:-
Short stroke design;
radial porting;
front through the shaft induction;
iron piston; and
steel cylinder liner


Specifications:-
displacement 3.5 cubic centimeters




Observations:-

Nice powerful diesel from around 1959. Engine is in nice condition. They had a red head and a pinky version. It's a short stroke design, so it's also a nice "finger-biter"... but when revs  are up...it has a lot of power. It came with the original box, with the manual....so that makes it for me very special item.

I must make a new con-rod for this little gem, because making a bronze brush alone will not leave enough thickness on the big end. So a new rod is needed and I will make him little bit thicker, to have save thickness for a red-bronze brush....A nice job for the nasty winter.. I will update the clip ,when the engine is running well!..

Thanks for interest in diesel-mania...more stuff on its way!

  1. Hi, have you dismantled the piston/conrod assembly yet? If not, you will find that the AM35 does not have a conventional wrist pin/gudgeon pin. The pin is carried in a steel carrier with an external thread, the cast iron piston is internally threaded to screw on over the carrier. This assembly can be tricky to dismantle as it is usually gummed up with old castor oil. Having re-bored a number of AM35's, I have made some simple tooling to do the job. If you are aware of this, please accept my apologies for wasting your time, but if you need help you can contact me at dcauser.262@btinternet.com and we can discuss it further. Kind regards David Causer
