There be a listeroid 12/2
« on: October 30, 2022, 12:02:57 AM »
Was able to pickup a used 12/2 that sat in the back of a garage for the last 10 years. Used a engine hoist and a tailer to load it onto. Yes these are heavy engines. It turns but is a little stiff from sitting. Thanks to 38ac, dieselgman and cobbadog for the rigging tips. It has some rust under the rocker covers and valve springs. Will probably take the heads of first and open up the front cover and see what is going on in there after sitting so long.

I have been on and off the fence about getting one of these engines for the last few years.  If I am going to build a decent generator set, I wanted one that was good on fuel, made the horsepower I needed and most of all I wanted slow speed. That is the main selling point for me.

I do not want a diesel engine like a kubota and others that have to run in there sweet spot of 2800 rpm. That is to fast for me to want to listen to. For me 2200-3000 rpm is a high speed engine esp for diesel, and dont want to listen to that racket.

Came across this 12/2 and the lady who was getting rid of it just wanted it gone. Guess it was her ex boyfriend who owned it. but he left the engine and took off a while ago.. Also got 60 gallons of diesel that was stored properly. seems good ,we will see. If it runs it maybe the best $$ i have spent. It will be a project for sure.

Very nice find! The original twins of this type are pretty smooth reliable power units. Congrats!

Field Marshall seems to have a fairly good reputation as far as Indian clones go.

Engine tag. Does BB stand for Ball bearing?   Also cip= cast iron piston?

   Thank you dieselgman. That means everything coming from you. Do you carry spares for this engine?
Are 6/1 parts compatible with the 12/2?  Parts  like valves and guides, piston rings , valve spring retainers and springs, and most importantly a starter HANDLE. They actually could not find it.. Thanks.

Thank you,  Got the spec plate pic posted. I am not sure if it has bushed or tapered bearings yet. I ASSumed BB meant ball bearing. I have not looked at it much yet. We were beat after loading and unloading this thing yesterday.

I am also not sure why the right side cylinder head is unpainted. Maybe a replacement at some point?

Looks like the external spring on the govenor is missing.

I wish my twin were rated for 660 rpm.
Mine is rated for 1000 and after many hours of "play" I could not
get the thing to work at anything under 800 or so.

Your unit looks like it would work fine with a 5 or 7.5 kw head.
All things considered it will probibly pull about 5 kw.

Neat project !

Thanks for the reply 32.  Can you decode that tag?  Is cip cast iron piston? Idi= indirect injection i think. What about BB ?
Is there anymore info on that tag that is worthwhile knowing? Can I figure out when it was built? 

Yes the governor spring is missing along with the starter handle. They could not find them.

I'm no help with the tag but I would think your idea of "idi" would be correct.

I think the bearing housing would be short with a roller bearing and longer with a bush type bearing
but I could be wrong.

Dieselgman would be your best bet for info and parts.

I would pull the heads and see what you have. You may get lucky and not have to go any further.

I will add that most of the time i spent on mine was not engine assembly. Time was spent on getting the
throttle linkage set up correctly. I am happy to say that after many hours of playing with it that the
cylinder temps are only a few degrees apart. I put a tstat on each head and am using a pump and an
aftermarket Honda type radiator and the setup works great.

If you read through my posts you will see the way I have mine setup.
