Original Lister Cs Engines / Re: 1940 CS 5/1

Thanks for the encouragement  :)
Got the crank out but still haven't removed one of the flywheels. Might have to drill the key out as the head on the key is long gone and welding a new one didn't help either.
The two main surfaces of the crank arnt badly worn but have some pitting, don't think it's worth sleeving them tho. The big end will get reground as the pitting on it is beyond DIY polishing.

Original Lister Cs Engines / 1940 CS 5/1

Hi all,
As the title suggests I have acquired a rather large ( to me ) Cs engine. Bought in pieces with most of the engine in red primer but the mechanicals all need overhauling. No pictures as yet but ill get some later. The crank is in poor condition so I'm in the process of battling the gib keys to remove the flywheels and subsequently removing the crank. I've got most of the parts to put this engine together bar the odd bolt and the injector bracket. The spec plate reads "CS37976" ( the second last digit was an 8 but has a 7 stamped over it) and it is a spec "5/1/35", any history would be appreciated. The engine has evidence of being seized due to water ingress hence the crank is a little worse for wear. The injector pump and injector I got working as it was seized solid but I must have put the rack in the wrong way as it's failing to stop when the rack is in the closed position. I also am having a mini-battle with the oil pump oil seal, said seal is an original metal and leather that is very seized into place, any ideas?
I'll try to keep this thread updated.
Josh.

Hi all, Been absent for a while I know but getting back on track now.
Having completed my startomatic box which I remade, I have a question. The wire-wound resistors found in most Brush type generator head, One small one and one larger on. On any set I've ever worked on have needed serious work and I'm running out of old spares to repair them with. I'm wondering is there a modern replacement for them or can I buy the wire to rewind them? I'm fortunate to have found a very damaged lister backup installation box (about 5 feet high) so I have a supply of relays but the resistors are the rare things now. Any help is appreciated
Josh.

It may take a bit of fiddling with that contactor as it is held by half wave rectified 230v pulses and made slow to release by the 4Mfd capacitor.
Right you are. I've figured out an appropriate array of relays to replace the box's innards leaving only the inductor. Not a "proper" startomatic I know but its the best I can do with the knowledge and equipment I have.
Kind regards,
Josh.

Hi all,
Can anyone tell me the voltage at which the relay coil LC 4 operates at? I need to build a replacement as is the running theme with this box, its shot. I presume it's around the 300vdc mark so a 240v ac coil should suffice?
Kind regards,
Josh.

Thanks very much, the advice will get the project rolling hopefully. Any recommendations for the size of the diodes? 1 amp? I took the relay to bits and have a few pictures for any other members to use. it can easily be replaced by a 12v (or 24V) timer and relay.
Kind regards,
Josh.

Also if anyone has the two control solenoids that sit on top of the engine to control the decompressor and fuel rack id be very interested in them as they are missing on this unit. I have a similar unit that uses a 240v solenoid connected straight to the output to trigger the decompressor? is that how its supposed to work?

Hi all,
This is my first post on the forum so please forgive any mistakes.
Yesterday I purchased a rather unloved Lister startomatic. It was completely seized and the unforgiving climate of the west of Ireland has not been kind to it. Took it to bits last night and have accessed the damage- one very stuck piston. Having accessed the engine I believe all it needs is a barrel kit and big ends. Now the startomatic side of things is another story. I'm quite confident I can get it working again but I would appreciate a wiring diagram but more importantly a diagram of the selector switch and the reset? switch as both are completely shot and I can't seem to reverse engineer them. all the relays are seized solid but I should be able to free them off. Also if anyone has a guide to replacing the diodes and what values to use and in which direction, particularly the one in the generator with a load of wires coming out of it, It would be great. I have (hopefully) included some pictures of the tag and various electrical gubbins. If anyone has spares for these I would be very interested.
Kind regards,
Josh.   
I've no clue how to insert pictures so They can be found here: https://drive.google.com/drive/folders/1ablw4uLkdiQhliJGK51p2h58uu--X9KK?usp=sharing
