Petter Industrial Engine Data Sheets

(1/5) > >>

listerdiesel:
As promised, I have set up the first 12 Petter engine type data sheets on our website.

http://www.oldengine.org/members/diesel/Technical/PetterData1.htm

There are 3 or four pages per engine, 40 pages including the menu page.

I have a pack of Petter info to pick up in SFO, the  week after next when we go over for a short break, that will be added as soon as we have time on our return to the UK.

There are a couple of Armstrong-Siddeley engines in there as well, petters took their business over (along with a few others!) in the days of ABOE and Brush Group.

Very Interesting!!!

Thank you for posting this. This raises as many question about the Indian varient as it answeres. For example the 116 mm stroke must be Indian and what about the larger bore versions such as the 95mm the 102mm and the 114mm are these also Indian or were they adapted from other Petters.

The angled fuel injector from he series two is seen on all the Petters I have pictures of but there are a lot of changes.

Thank you again.
Doug

I've had a chance to realy look over the specs of these Petter types and I now see some intersting relationships between the Indian varients and the originals.....

114.3 mm was a PVD standard bore piston, perhaps it was the source of the liner and piston for the Indian AV1 big bore clone.

PH1 clearly shows the Petter oil line for the rocker box tapped off the front of the engine oil gallery just like my clone...

AS1 shows a combination cam and crank output shaft at the front of the engine simmilar to others I have seen made on some water cooled Indian wins and triples.

Wonderful stuff, it leaves me wanting more. Was there any  parts interchangeability between the different types?

Non of these engines share the gear oil pump that mine has, I wonder it came from?

Doug:
Peter I have another question for you a little off topic about Nordberg....

Did they manufacture other industrial equipment? Specificaly I ask this because there is a Hoist at the mine where I work installed sometime in the late 1930s with the name Nordberg. Since its an internal shaft this hoist was decommisioned and left intact and its in a dry area so the preservation is nearly perfect.

Only an electrician could call a 1000 hp hoist a thing of beauty but it represents a technology thats gone all mechanical controls, iron casting and heavy steel forgings bolted and rivited that today would never be made in one piece but welded and run by computer.

I guess I need to go to 3800 level and snaps some pictures if your interested. Quality won't be good I'm afraid the power to the hoist room was 25 cycle and we don't have any services to electrical room for lighting.

Firstly, the oil pumps were Hobourn-Eaton types on a lot of the engines:

PJW, ASJW, AS, PJM, AC2, BA1, AA1, AB1, PHWM, AV1 LAB, PH, PJ, AVA Ser II, PCM.

Plunger on some:

PA, PAK, PAZ1, AV1 SerI.

Splash on some:

A1, AP1.

Gear on some:

PDV.

That's after a quick flick through the manuals.

Hobourn-Eaton pumps are the concentric rotor types with one lobe less on the rotor than the outer stator, which in fact rotates as well. They are widely used in power steering applications where their compact format and low parts count is a major selling point. BMC used them on the original Mini after years of gear pumps on their engines.

Regarding Nordberg, yes they had a very big machinery manufacturing side, they made all kinds of rock crushers/graders and conveyer lines etc etc.

I have a couple of contacts in the USA who have supplied me with additional engine material for the website, let me know if you want to be put in touch.

Missed your question in my first reply post.

The AVB is more likely to be the source for the AV1 big bore clone, or the B series. I haven't got any data on my own AVB and don't want to pull the thing to pieces to check!  The B was a big water-cooled lump as well, there's one down on the Somerset levels off the M5 motorway that I looked at a couple of years ago, probably still there out in the weather....
