I'll up load photos later today once Home from work as I only finished giving them a quick clean, and the glass is all stoored in a hard box in loft to stop brakeage

Hope pic helps, yer I thought stock but wasn't 100% ive inspected the piston (be it still on the engine) and there is only a very slight wear on the side (as an ex engine builder for alfa) the wear dosnt concern and a quick wipe with emery cloth and the coke is coming strait off, all rings are free and coke free, only thing missing was the bottom oil ring but has a grove for it.

I've started to strip and clean the ha2 now I know it ran so I can clean it up and then once national is fully running will rebuild it. I've removed and cleaned all the top end im in the middle of cleaning piston, I do have a set of rings about (no idea why) but the number on the pistons don't match to anything. There genuine lister pistons and liners and are in very good condition so will prob hone and reuse, The numbers off the piston are part number 531-18250/7 (the 8 could be a 9 as has a bit of dirt on it but it looks like an 8 when I look at the patern number has a 9 in) Any idea what this relates to e.g. stock or over sized?

Not really found any new ones, except my very cheap poor quality one but that still wasn't new. Mine are old duplex ones but not sure how old,

I'm in the middle of going threw my stock of boat bits ive built up over the years and after a good going threw and realising I have bould a lot of rare but not needed parts im going to start getting rid of some of it, some im keeping but have lent to people, but I have 4 back cabin paraffin lamps. 1 is pretty rubbish It didn't cost much as it still had price on but I think was an attempt by someone to make one and apart from the globe and chimney has been binned it wasn't worth anyones time. 2 I have are the same i bought them years ago from someone who was rebuilding a motor and butty and putting conversions on and wasn't keeping much and 1 of these is going into my motor Towy. I was going to keep it to put in a butty if I bought one but thats not happening for a while now so will sell And the last one is one im going to sell. Im in the middle of cleaning them up as covered in dust and not been cleaned in years. there complete except for the smoke bells (these were glass ones not brass for the matching pair and im keeping them) and other one i dont think I had one for it. Anyways they hold paraffin and work have solid brass sconce on them and locate into the sconce, have glass globe and chimney. Any idea what there roughly worth? I'll post a pic tomorrow, once got an idea of price I'll list on here in the for sale before I ebay them.

Given that marine jp3 with box running sold for 1.9k I would say it was well over

Well all electronics removed bodged fuel bottle and line connected bleed and pop fired straight up. Only run for a min but It def had a variable throttle, and will tickover nicely with my finger between the lever and the stop bolt. Its abit smoky but im not sure if its just build up of crud or if the rings leak as ive noticed a fair bit of oil in the exhaust but that's OK as will be rebuilt. I'm guessing the max it will run is 1500rpm rather than 1800rpm as the side has a pin hole and the lever won't go past the pin lining up with the hole. (This is fine as if so not bothered about changing unless easy to do but it also allows me that little extra leway of not putting the engine at full stress) The nice tick over is just under 1/2 the full movement of the lever so guessing tickover is around 500-600rpm?? Sorry I've no idea on ha engines as to what does what, but I know there good reliable easy running engines. Fr2, national, bolinders, jp2 I can get my head around,

True thanks tony

Thanks, I wasn't 100% sure as alot of older engine you have to fill the sump direct and on some ha ive seen it had fillers on the head and on the crank case.

Right ive looked and its got a variable electric solenoid that then has a pin on the end of the governor, the pin pops out onto a switch this switch makes the solenoid drop the rpm when it pops back in the solenoid speeds the engine up, you can also lock it in full 1500rpm im guessing for starting but as soon as you touch it or move the speed its on a spring load and it automatically runs back on the solenoid, ive now removed all the electrics and will run again, im guessing by the way I saw it work its got fully variable speed but is set to hold at the given rpm for the engine load on the power unit. It can also self start and self stop (although this dosnt work due to the alternator unit being dead) but will manually run.

It will run but unfortunately she don't have a lift pump or the slot in the crankcase door for one. So got to bodge a tank or something above the fuel filter to try and get fuel into the injectors, I have a big day tank on the boat if it ever got put in so the purpose its being build for means I won't need one just be easyer for setting up and running at home. I've also going to have to get a diffrent crankcase door as there dosnt seam to be a way to fill the engine with oil, unless you just poor the oil strait in threw the heads?

Engine is now parted from the alternator unit, Engine will be stripped down and converted, I maybe getting another for some spares

Its got an electronic speed controller on the side unless this is to turn the engine off

So an update to my engine, I have now found out what it was used for and why was replaced, The engine is fine its the dynamo / alternator thing that failed. It was installed into a railway carriage to give 240v to buffet cars and lighting on coaches when pulled by a loco that couldn't provide power, it was then bought (coach) by a small railway society and used until a few years ago when one day the alternator side of it (240v supply) failed, it was then removed and a replacement unit put in. This was then kept as a spare engine, but they decided to sell on and the funds go towards a diesel loco restoration. This will explain why it has all the ducting on in and extra air feeds to all electricals as it was in the back of a guards carriage. Its got the perfect engine for me as has a bit of history to the engine.

Look quite a nice engine quite neet

I thought was a marine or ship power generator set due to all the ducts and air cooling for a confined space Thanks for wire diagram though! But will be loosing it all to convert to marine and bolt a 2g box to it as ive now found there the same as all h series and frs and will hopefully find a marine timing cover or at least one to copy or make a plate to fit to the stock one

Pos it has a heat cooling outlet shield on and all electrical are cooled too with vents on, once its stopped raining next week I'll get it out and get more details off it ive not had it long. Its also got an electrical decomposition part on the levers too, so has auto start and stop from electrics

Yes but it then dosnt quote it its an industrial or marine engine Or was it only the marine units that got a marking for use?

No national is 3/4 back together I've been quite lucky with it that I have been at bclm but if had been anywhere else I would have been stuffed. I have been looking for a spare engine for ages really wanted a jp1 k1 ect but trying to get them at sensible money, I did find a jp1 but they wanted 1k and by time I rebuilt it I was on for 2.5k, so if the national does go wrong I've got an engine I can throw in as a temp with very little work to get it in and running.

Mine says 3161ha2i2 Which would put it 1952? Unless the i is ment to be a 1 but then it dosnt state if its industrial or marine

If you mean mine it was part of a gen set well still is but i think I was or has been installed either in a boat / ship or a confined space as mine has the cooling scoop on the side for the hot air to be vented and also has a shield around the flywheel with a space between the engine and gen for air but also all the electrics are air cooled too and all have air outlet scoops of some sort. Its all a bit odd as everything is electronically controlled even the decomposition is All easy read info is 10kva Cycles 50 Single phase 240v Slipring brushes 4 Do bushes 4

Thanks, looks like best option will be to run it off the flywheel end, good news for me as means I can use my stock national box

How did you get on with air flow threw the flywheel? Looks a big but nice setup. My other option is to put a shaft threw to the box with a cover over it

I've got a ha2 industrial engine 1952 year, its missing (compared to full marine) a few bits but its an odd engine as its got alot of marine parts on it compared to other industrial engines, It already has variable speed control be it electronically controlled, so with all electronics removed a fabricated speed lever can easily replace this. Its missing a hand starter handle (marine hand starter) should be easy to fit one Now the only thing it does say is 19hp at 1500 not 22 at 1800 is this just down to the electronic controller (replace with lever to be same) or do these have diffrent governors? I can see diffrent is the end plate as marine seam to have a extra bit casting and the bolt holes for bolting a gearbox, this isn't a massive problem as its either a case of replace the end case or make a plate to bolt onto it. Lastly are the ha gearboxes the same as fr2? If diffrent im guessing if a custom end plate is made you could mate one to it?

Isn't ascot the fuel boat that looks rather sorry for itself?
