MARS 5HP DIESEL ENGINE - Completed Restoration of Engine No.32

- Опубліковано 19 жов 2024
- See the results of a painstaking two year restoration of this rare diesel engine. One of four known in the world at present.
Mars diesel engines were made in Brisbane, Queensland, Australia and were not Lister clones. They had thicker 2 3/4" crankshafts and thicker internal pushrods as two of many things that set them apart.
Not one part was interchangeable between the two types.
The Lister engine were great engines but were prone to breaking or twisting their crankshafts in industrial workshop situations.
As the story is told, they were not strong enough to handle the start up load or torque so the Mars company invented a better mouse trap as they say.
An extraordinary amount of attention has been paid to getting every single part of this engine restored to its original factory specification and finish.
The paint was matched exactly to the original factory colour (modern day equivalent is Wattyl R55 Claret). An original intake silencer was sourced and measured and a new one remanufactured in the same method.
The Mars engines were sold from the factory minus the fuel tank, exhaust pipe and water cooling tank as the customer normally would have fitted these for the environment. Quite often the exhaust pipe would have come straight out of the engine and through the factory wall, and a 44 gallon drum would have served for a cooling tank.
All engine bearings, rings and seals have been renewed with brand new factory specification replacements. The flywheels are as per original factory installation and had never been off the engine until the restoration.
The tolerances between the flywheel and the crankcase were that fine that there were literally less than 1/8 " clearances so great care had to be taken to remove and reinstall these right the first time.
As well as having the engine serial number stamped on the head, the flywheels, gibb keys and keyway in the crankshaft are all stamped with the engine serial number which showed an incredible attention to detail by the company.
The injector side of the engine has an 32I on all its components where the other side has only 32 stamped.
The oil seals on the crankshaft were the very first of the new modern type oil seals that we still use today.
Mars were sure ahead of its time in 1942.
The Pyrox injector pump was also fully re-kitted and tested. A new high pressure fuel line was made and everything just came together perfectly.
Custom built fuel tank brackets were made and matched to fit with the engine with a 6 litre tank plumbed to gravity feed through a filter to the injector pump. Nice!
A heavy duty custom built transporter of plate steel and C Channel was also fabricated in an industrial style of the period, and finished in a Penetrol finish to enhance the raw steel. Yes it is heavy.

I had never heard of these engines before, but it looks beautiful. You did an amazing job restoring it! I've always been fascinated with antique machines.
I just love that engine. Great job on the restoration. On items that old a ''true to time'' restoration is a struggle on items that were common. I can only imagine how hard you all worked to bring that rare old engine back. Just everything trying to get specs having to build or pay for fabrication of parts. The thinking trying failing re-thinking inventing new avenues solving problem after problem just to get on to the next tier of problems. I truly respect the time dedication and rededication it takes to make a project like this happen. Every person after the first owner dreamed of that engine being what it is now. People gave up 40-50 years ago and you seen the job through today. I hope you really enjoy that engine you sure as heck earned it. Too say cool old just does not begin to describe this piece. That old engine really sounds great.
Thank you kindly for your words. That gives me energy to do more. :)
Awesome Job !!!!! It looks like it could do the next 50 years of work in this brand new condition !!!!
Greetings from Germany !!!!!
Gidday to you mate.
Man, Thats a real Beauty! Perfect!! Great job. One of the best I've ever seen.
This is a beautiful engine. You sure did a nice restoration on it. Thanks for sharing. From the USA.
Wauw MR Hatman. BIG thumbs up !!!!!!!!!!!!!!!!!!!
Awesome engine and nice piece of history. Great job on resto
I would build a little tug boat just for this darling diesel !
Perfect work!Congratulations.
What beautiful works of restoration. congrats! Must say the sound these engines make brings back lots of memories of the old sawmill my grandfather used to own..... do you have any more or are you working on any more?.cheers
Lovely restored engine!
Good on ya mate.
Best regards from Sweden.
Very good job, sir. I like how fine tune the engines are.
Brilliant... thank you for saving and sharing. (US)
Nice work bringing back a classic.
Sounds a lot better from the last video!
John Hovan It was a brand spanker mechanically in the first video so it was was pretty tight inside, the injector pump was also failing which we found out a few days later as well. All fixed now and that was its first proper run under some load. Thanks. Phil

Fine job mate ! A big change from 2013 ! When your at the Kingaroy rally, show us how the Mars looks there and post for your American friends .
Great restoration, mate. Sounds good too. Cheers from Norway :)
... brilliant engine, m8 ... thanks 4 posting ...!!
outstanding!
Well done! :)
Nice!

beautiful job!
Devon Edwards Thanks Devon. It took a bit but we go there. Had to re kit the injector pump though as it was failing on the first video. Cheers. Phil
seems worth it - do you tour with it? Car Shows etc?
Yes mate. this engine will be at the Kingaroy Vintage Iron Rally on the 19th - 20th September

Sweet job... Congrats!
Good work!
man so beautiful congrat to you sir
After watching a water cooled engine pump water in a circle all I could think was, diesel powered hot tub.
nice soled steady beat
Very nice!
One of these with an 'underground' muffler and a genny - goodbye, power company.
Amazing!
Someday those barrels will get full, someday!
Lovely!
Excellent work, would love to see the old girls internals.
very cool!

Big old thumper... lovely to see!
Fantastic job; great bit of Aussie engineering, i have a couple of Lister CS diesels; didn't think they could be improved on!!! does the crank have plain bearing or roller bearings? thanks for sharing and well done indeed. A+++++++++++++++++++++++++++
The crank has a plain babbit bearing. :)
stunning music 😍😍
Very nice job on the engine! I'm wondering if you are "short circuiting" the cooling tank by not having the lower cold water line to the engine come off the bottom of the tank?? The coldest water in the tank should be at the very bottom and it would make sense to tap the tank there. Taping off the bottom would force the entire surface of the tank to be used for cooing and not just the top half.
Hi Jim, the bottom pipe actually goes into the tank around a third of the way from the bottom but once it goes into the tank it has an elbow inside that takes the pipe to the bottom to draw the coldest water. Hope that makes sense mate. Cheers. :)
Nice job! :-)
Nice man if you don't remember me I was Gameday
Ever considered running a generator off them? I love watching them run, I could watch them forever but it feels a waste to have it running and not doing anything with all that power, dont you think?
ijustwanttoseetitty yes, but a bloody good size generator, just ti make it work a little.

Put it is an oak framed cedar planked heavy 16 foot skiff,tiller steering.flat bottom.Good for 5 knots.
How efficient is this compared to modern diesel engines of the same size? Also a power comparison. How much hp would a modern diesel engine output at the same size?
It is very similar mate.

Nice I have one in India we r still using to pump water in farms
That water in reservoir for cooling engine,how hot does it get after longer running ?,as i not see there is any fans or something to cool it down.What is normal water temperatures for that engine to running all day long ?.
Hi mate, the cooling tank is right next to the engine. The engine can run for around 7 hours before the water temperature gets to be very hot and even then it is ok to keep going, although we have not run it longer than that yet.
Cooling is achieved by convection cooling. The bottom pipe draws the colder water from the bottom of the tank and once it has gone through the engine the warmer water goes out the top pipe to the top of the tank and then is drawn down through the coller water to the bottom and so on.
I wish I had one to put in my yard! The water tank however is seriously ugly, do you have plans to replace it?
The cooling tank that is beside the engine is as pr the original specs and is galvanised and soldered as per the techiniques of the day.
The tank that has the pump water in is one of many I have and is simply a half of a 44 gallon drum. Yes I have replaced this. :)
Are those barrels ever going to fill?
No, the barrel is set up on a recirculating system where he water is taken out the bottom with a 3 " hose which goes 3 feet along the ground back into the centrifugal water pump. :)
crazy how we have come from this to crotch rocket motors being affordable
how much cooling is achived by this methoud of drum??? time of safe running
?
Hi mate, the drum that you can see the water flowing into is not a cooling tank. It is separate. The cooling tank for the engine is beside it and the engine will run for 7 hours straight before the water gets anywhere near boiling. :)
does this require cooling of somekind?
Yes mate. The cooling tank is sitting beside the engine on the transport. It works by convection cooling.
Why do you bleed it first? To get air bubbles out?
yes
AkubraHatman and
You have to bleed it first, so that it will prime the system, otherwise you will dry start it and badly damage it. However, this only needs to be done if you replace the Untagleeden bearings.

Those look like one could make power genorators if know how.
Betcha this things got torque eh?
What is the displacement? and do you have the bore x stroke dimensions?
I've always wondered, what's the /hour fuel consumption on these things?
5 litres per 6 to 7 hours
So, what were these Used for back in the Day?
Driving water pumps, generators and other driven machinery. Mostly they were used in factories driving a line shaft and multiple machines
can you get parts for these things?
Yes but they are very very rare now. 3 hp engines are worse. :)
same one problem. my engine is high-speed how to control it give me solution
Adjust the idle screw down. :)
I want to learn each and every thing about it like working machine parts. what can u do? ?
Please feel to email me at akubrahatman@gmail.com and happy to chat to you. Phil. :)
What is the fuel consumption on that engine
I can run the engine for 6 hours on 5 litres of diesel, under load.
look at her goo!!!
very good but open Peres. Think you
yeah evil robots wanting fingers to eat!!
नोट वनदी के वात के हसी वाले किससे
were i stay at in mississippi at a place out towards a oil feil call lake mary theres about 20 of these motor just rusting away an there only one still running a oil well people ask why he dosent replace the motor with a up to date cummins he like he day i replace that motor is the day the well drys up or the day she locks up until that day she be running here forever lol , that well gotta be over 60 years old or more
