Engines / Re: Alpha LPW/S water pump sleeve seals
« on: February 19, 2023, 10:07:02 AM »
So when you overhaul do you get it out and change both seals or leave well alone? From the deathly silence on the forum I wonder if people realise it is there

Engines / Alpha LPWS cylinder head resurface
« on: February 18, 2023, 08:19:29 PM »
 In another post Dieselgman makes the comment “Your LPWS head cannot easily be resurfaced and the usual fix is a new cylinder head”

Does anyone know why this is. Is it different for the LPW head?

The sleeve is item 7 on the water pump drawing. I’m sorry if I misled people it’s on the cylinder block not the cylinder head. It’s between the water pump and cylinder block

Engines / Alpha LPW/S water pump sleeve seals

This probably a silly question but there is no mention of it in the manual. The sleeve 751-40441 between the water pump and cylinder head has two o ring seals shown on the parts list. To get at the inner one do I just waggle the sleeve about and pull the sleeve out? It seems pretty rigid to me. Will it be corroded in?

I've just taken out the injectors on my LPWS and used a spanner on the flats between the two pipes, they unscrewed without incident.
Yes I did think of doing that but don’t want to split the injector by accident so I’m hoping to adapt a socket to reach the bottom set of flats
I’m hoping to use a friendly machinist! 
Thank you anyway

The injector shown in above photo is not an LPWS injector, but from an LPW engine. When I said earlier about boring a long reach socket out, you only bore out material from the upper inside of the socket. Leave the spline as is. The normal drive spline will also fit over the injector stubs as they are a slightly smaller diameter. The problem is the internal space further up the socket with is normally designed with an internal diameter just big enough for the stud to go through. Hope that makes some sort of sense.
Hi Diesel Engineering thank you that makes perfect sense.  You don’t happen to have a modified socket or injector handy you can measure  do you so that I can bore one out before going to the boat? I will need the socket size (M?)and the injector length from hex to top. Thank you for your help. Robert

Hi Robert

I've just looked up a photo of an Lpws injector, is this yours?

If it is you won't need a socket to remove it, it should just pull out.

At the worst way you'll need a slide hammer with a fitting to suit the connection for the injector supply line, the other photo is one I made years back from bits out of the come in handy pile for pulling injectors from Land Rover engines.

The local injector service shop will probably have one laying around or you may have to buy a new pipe and butcher it.

The fab shop mentioned earlier should be able to find you a lump of steel for the hammer and another for the shaft or you can get one for around £20 on eBay and either have the union fitting welded onto it, like mine, or get a nut welded to the fitting to make it detachable, then should you ever need it for something else it becomes multi purpose!

Cheers

Hi Stef I'm sorry I can't seem to post a picture. No its not that one. It screws in and has 2 stub pipes at the top for the leakoff pipes. If you google LPWS Injector there is one very similar on ebay 751-40760. Later ones that I have have I think a larger thread. A long socket should fit over the top but I am worried about the leak off pipes fouling the socket. I am not down at the boat now but trying to get all my ducks in a row before Xmas!

All you need to do is buy a standard long reach socket of the correct size then find someone with a lathe who can bore it out to allow it to go over the injector.
Do you mean just skim the splines inside the socket so they don’t foul the spill pipe stubs but still grip the injectors or will I need to die grind some of the splines completely out of the socket?
Thanks a lot for everyone’s help. It’s not the depth of socket that’s the problem it’s me worrying that the spill pipe stubs will foul the socket and prevent it going far enough down robengage the hexagon

Engines / Lpws2 injector removal
« on: December 16, 2022, 09:29:31 PM »
I have a 400 series build 48 lpws2 engine and I want to check the head gasket. I need to take out the injectors 751-60290. (This the type with the 2 pipes sticking up on each side). It is recommended to use a special socket which I don’t have (it is £180!)
The boat and engine are a distance away so I was wondering if anybody new
What size socket I will need?
Can  modify a standard long reach socket?

Thanking you in anticipation

Engines / Re: LPW2 Build 902 change fixed to variable speed
« on: January 22, 2022, 05:07:12 PM »
Thanks dieselgman. Do you think the governor arm for the fixed speed I have will be any use with the variable speed weights etc I need for variable speed or will I need a complete new arm?

Thanks that’s what I intend to do. I’ve got some 3M scotchbrite to scuff the red primer.

Thank you for all the advice. I visited the vapour blaster today and he is a specialist in maintaining top rally cars. He reckons vapour blasting will not remove paint but offered to use grit but said I could have a problem with contamination. He said if the paint is sound don’t take it off but scothbrite it to key it (he gave me a sample) and paint over it. He showed me an engine he had done like this and it looked very good. He just used Halfords engine enamel with a brush
Cobbadog thank you for the advice re the POR15 I wasn’t aware of the short life.
Dax and Hugh. I have used caustic dips on wooden furniture and it was brilliant if messy. My problem is I only have a small shed and yard and haven’t really the room.
As an aside I worked in the North Sea for ODECO. We used caustic in the drilling mud and some water dripped on flakes trapped in a grill above me and burnt my back! I found out after the event when I went to bed
I think I will go the scotch brite way as the paint is quite sound. It was suggested not to worry too much about masking as the paint can be scraped off before it is too hard
As with all these jobs I am discovering there are more problems than I envisaged! Thank you all

I have found somewhere locally that can vapour blast it. What I would like to do is to get it vapour blasted then rebuild at my leisure - I am not the fastest worker and it may take a couple of months! But I don’t want it to be rusty when I finally paint it. Any ideas? Can I coat it with wd40? What to people do?

Engines / Paint Removal LPW
« on: January 09, 2022, 11:05:05 PM »
I’ve broken down my engine and removed all the grey paint from the aluminium parts of my engine. I thought this was going to be the tricky part. I am now onto the iron head and block but having difficulty getting the red undercoat/primer off underneath the grey. I’m planning to paint with POR15 engine enamel. Does anybody have any suggestions to get it down to bare metal?

You’re probably correct but if S-H hadn’t taken it over there probably would be no new Lister engines at all. I don’t think that they claim to be anything that they’re not. End of an era (almost!) all best Robert
