Southern Cross ETB diesel engine
« on: February 13, 2019, 12:28:10 AM »
Hi Guys, I am awaiting the delivery of a Southern Cross ETB 2.5 HP diesel engine. Manufactured in Australia circa 1950, they were also manufactured briefly in South Africa. This engine has sat in a mate`s shed for the last 20 years. I have finally persuaded him to part with it for free!  :) 

Sadly it is incomplete, missing the fuel injector, pump and fuel lines. The originals would have been made by an Australian company called Pyrox, who manufactured injectors and pumps under license from Bosch.

I have been unable to find much out about the missing items but believe they are very similar to the units used on a Lister CS 3/1. I suspect that I might have to change the injector nozzles and fiddle with the pop pressures a bit to get them to work properly. Any thoughts please?

I have attached a photo of a complete ETB I found on the internet, probably a breach of someone`s copyright, for which I apologize in advance. I will post photos of my unit once it arrives.

Perhaps Rob at OldTimer Engines could help with a suitable pump?

Thanks Mike, I`ve been looking at a few Youtube videos and it would appear that the injector pump timing must be adjusted with shims as there is no access to the plunger or cam that drives it. Interestingly the fuel injector is side mounted in the head.

I`ll flick an email to Rob once I get the engine here.

Always wanted one of these most Aussie of engines. What could be more Dinky Di than something called " Southern Cross"?
For those that don't know, that's our most prominent constellations of stars Visible here and features in much of our poetry and cultural history.  It is also the constellation that is featured on our flag.  There is another constellation which is similar called the false Cross because that's what it is. Real Aussies aren't fooled and know the difference and how and where to find the Southern Cross in the night sky. 

Where I am here at certain times of the year I'm right under it which is pretty special.  most times, it is in the south.

I would like a YTB model which is 10 Hp I believe but any of these is a real find no doubt.

From what I have read of the things, they were a local attempt at knocking off the Lister market and a lot of things were done the same and similar on them.
I wonder if the yanmar type Pumps are the same?  Yamnar were doing engines at that time and the modern versions as well as the China Knockoffs work by shimming the pumps as well. Just a simple plunger design. If you could find a pic of an original southern cross pump and put it up would be easy to compare. The china pumps are easy to get and cheap.

I got an idea there are some other engines these were pretty interchangeable with as well. Might have been Moffit Virtues.

Hi Glort. when I bought my Lister CS, the farmer also had a YBT. I chose the Lister because it turned over, while the other was seized. Parts for Lister engines are readily available,.New parts for old Southern Cross engines would have to be manufactured at huge cost. That said, you only have to look at the work being done by 38ac to see what can be achieved by a determined and skilled individual.

When it gets dark here I can see the entire Milky Way in the sky, No wonder that earlier people worshiped the heavens and learned to use them to navigate the globe.

I'm "centrally located" aka middle of nowhere, at 5600 ft and the night sky is very bright here too; the plane of the Milky Way is obvious. A big reminder of how very small we are, even within our own galaxy.

Years back I read something to the effect of....
