Hello Martin, my first posting on here!
Yes, the PH2W does have anodes. They are on the starboard side of the block (assuming flywheel end of engine points forward if your engine is in a boat). I'm assuming your engine is identical to mine, which is a PH2WRMR. You have to remove the water inlet manifold beneath the injectors.
I'm not an engineer, so I can't get too technical!
A friend of mine has the same boat as mine, with the same engine. We are overhauling the 'water works' on my engine at the moment.
You may find it very difficult to find new anodes. I have two original ones. My friend, who is an engineer, is using mine as patterns to make up some new ones. If you give me your email address I'll try and get the drawings and email them to you for you to get some made up from, if you wish? Doug |

Ah, just checked your profile, Martin, so I've got your email address.
It will be a little while 'til I can get my hands on the drawings, but when I do, I'll let you know. |

You're welcome, Martin. Will get onto that as soon as I can. Nice to be able to help each other keep these old beasts running. |

Managed to get manifolds off tonight at last, all i can see is brass plate in between the manifold and the block plus a lot of corrosion, could this be the remnants of the anodes, the hole in the center of the plate is smaller than the manifold bore so are the anodes tubular and attatched to the plates and inserted into the manifold/block ? |

Yep, thats it! Mine was the same, just the plates were left, with a load of bits. I take it that your engine is in a seagoing boat, ie salt water, like mine is? I'd assume those that run in canal boats don't suffer the same corrosion like ours do.
The part number, by the way, is PN 257678, but when I last enquired several years ago, I think Lister-Petter just referred me to 'Sleeman and Hawkin' (somewhere in the West Country)and at that time they had a few left at something like £30 each. It was my friend, with the same boat as mine, who enquired more recently and must have been told they no longer were available, hence going down the route of making up new ones. See the link below (if it works) for a pic, to see what a new anode looks like.

Thats fantastic doug, is that the one you made ? they look like a piece of cake to make. Only one question, how is the anode attatched to the brass, does zinc have a low enough melting point to act as a solder, also it might be a good idea to double the length of the anode and have it protruding into manifold and into block providing there is enough space. and i bet they dont last long.(better stock up on gaskets and get a handfull of anodes)
anyway i will post any progress ,the engine itself was a auxilliary engine on a cornish trawler and was hardly used but stood full of sea water, soon to be fitted in my 16 ft cornish cove boat. need a scoop bearing housing for the stern tube as well.
much appreciated Doug |

I would love to say that was one we made, Martin, but that is one of the original 'new old stock' ones.Regarding how the anode is attached to the plate, I'm not sure. Its not screwed in, it seems to be pressed in somehow. What I'll do is, I'll take another piccy in due course of the other side so you can see how it is attached. I'm not sure about the melting point of zinc. I agree it would possibly be a good idea to extend the lengths of the anodes if possible. It is my friend who is making them,and I could put it to him. At the moment he has his boat ashore and he's concentrating on re-painting and antifouling. As soon as I have any more details I'll pass them on to you. I have suggested to him that we make a load of them up, and then maybe we could send you some, and would just ask you to contribute to the costs,but I'm in his hands, so it all depends upon him really. Will see what I can do anyway.
Our boats are 32' wooden sloops. My friend's was built in 1965, and mine was built in 1968.
Once the engine is back together I shall repaint it in its original colour scheme of very pale green, and then I shall attach some original style Petter diamond shaped transfers.
How is the water pump on your engine? Mine is being rebuilt from a combination of parts from original pump, pump from spare 'donor' engine, new parts, and parts from a 'new old stock' pump,almost identical but sadly not able to be adapted to fit my engine!
Here is a link with a piccy of my engine....

Hi Doug, no problem contributing to costs, as for the pump its a jabsco 5870(only ever fitted to lister/petter engines) which works well and spares are readily available (according to web page)http://www.jabscoshop.com/wizard/item.asp?ls=5870&v=9DFF7865504046B1A8B45F8CDBED 5653&code=5870
Thinking about those anodes, they could be made by press fitting zinc tubes into the manifold once the manifold bore has been cleaned/re-machined, possibly omitting the need for the brass plate. Just a thought.
All the best
martin. |

I'm glad your pump is running fine. Just be aware that wherever it says on the webpage 'click to enquire about this part' means it aint stocked anymore! I ordered double of pretty much everything else that was available, so that I have a good supply of spares for many years to come. I'm lucky in that a load of engine spares came with the boat, and that I've also aquired a spare engine in working order, complete with the same gearbox and reduction gear!
One of the reasons for doing the 'waterworks' overhaul was because the engine occaisionally started to run dry. Hopefully a good clean out of scale and an overhaul of the pump will have cured this.
At the Beaulieu Boat Jumble I found a couple of new old stock 5870KD pumps. These were fitted to Kingfisher Diesels. They look identical, but closer measuring revealed the holes for mounting them onto the Petter engine are very slighty spaced differently from the 5870 which is a shame, but at least I can cannabalize the bodies for spares.
You could be right about the method of fitting the anodes into the block. Again, I'm in the hands of my friend on the way he decides to make them up. By the way, regarding length of time that they last, I think you're right, they don't last long at all!

Some i made earlier, 30mm zinc rod machined to a tube, cut to length and soldered to the brass plate. |

Any chance of getting hold of a working Jabsco model 5870 water pump for my ancient but well-running petter diesel. I think the cam is worn |
