Lister Petter TR2 1992

[South Prairie Larr]

Newbie here but I've been lurking.   Just purchased a used as is TR2 with 10 KW generator. Pulled the heads and remove carbon, cause it would not turn over. Got all the parts to do a top end but the cylinders look good. One of the injectors is bad. got new nozzles, would like input on how to get them apart to change them. No diesel engine overhaul experience!  Also should I go through the valves now or put it back together. It will only be used for power outages a few time a year. Thanks SouthPrairie Larry

Welkom, It will take until the weekend to start having reply in general.
First i dont have experience with a petter.
The basics are the same. So lets start make pictures all the way from dissambly ( nobody will remember after a week month the exact way) and it is the perfect drawing to put it all back again.
It is the best to remove as much as you dare. I know there will be comments to remove all, but to start do not go to far.

greetings from Greece

Larry,

You are a pretty gutsy guy taking that Lister TR apart without any diesel mechanic background or experience. I hope it is not getting discouraging for you with all the little problems that have come up in the process. At any rate I am thinking you will know your machine quite well by the time everything is sorted out and back together! I will consider adding my 2-bits to requesting some additional subdivision on this forum to deal specifically with the newer Lister models for folks like you.

Best of luck!

can you turn the engine over now that the head is off and you have decarboned??

i have a ts2 (same as tr2).  i personally would just visually check the valves for seating, check the injector spray, reassemble and get the machine to run before i decided what work i wanted to do.  these are tough machines.

Captain Steven,
I have been slowly working on the TR2, As soon as I pulled the heads it would turn over. Front piston carboned up real bad. Evidence of rain water in thorough exhaust valve, clean out carbon some pitting on top of piston.  Pull out valves, exhaust valve and seat pitted. Heads off to machine shop for seat clean up and valve guide replacement, labor $40.00. Went to install new valves and the groove for the keepers to small, back to machine shop cut bigger grooves, $20.00, Machinist lost keeper in chip tray email dieselgman to send replacement. Was getting ready to install the stub shafts that hold the valve rockers, and got looking at the oil holes and noticed three of the stub shafts had not been cross drilled for oil to get to rocker bushings ,too hard now to drill, funny this engine probably has over 5000 hours and it still worked this way, must be lots of splash in the top.
 I don't have the luck to not replace them, so 3 are on the way from England.
While the heads were gone after pulling the injectors, front one rusted up and pitted. I had new nozzles but was to chicken to try to take them apart. I hooked up the injectors to the high pressure pipes bleed out the air and spun it over by the starter, rusted one nothing but other had four spray pattern but not even, exchanged front to back and back to front no change. So off to the injector shop $50.00 labor.
 I all ready had cylinders and pistons and after seeing rust and pits decided to pull cylinders and pistons, front piston had second ring stuck hard so I guess I did right. On to the connecting rods small bushings need replaced, off to the machine shop, replace bushing and ream to fit piston pin $20.00 labor. Picked up today.   South Prairie Larry

sp larry.....
in for a nickel, in for a dollar.  i have owned many tr2 and 3's which never had there heads off with 40,000 hours.  it is easy to spend big $$$ with the cost of lister parts.

In for a peny in for a pound sounds funny in "American" lol.

Larry, you're getting off cheap.  I had one injector "cleaned up" and the pressure set $100!

Stan, But I didn't say that the shipping from Fairbanks Alaska to Buckley Washington was $950.00, so I need a few price brakes     South Prairie Larry

[South Prairie Larr]

Finely after a few weeks of honey dos, finish planting Christmas tree seedlings, till up the winter rye, add river silt from the last flood and a load of cow manure to the garden. Then change the front brake rotter's on the wifes car, then its making the bad front bearing sound on the front side , get the unit not the bearing , I remember the old days when....   now all quite and all the yellow lights in the dash are off. Got around to putting the connecting rods into the new pistons, used my fancy hose clamp ring compressor and put em in the new cylinders ready to go back on the bottom end. And yes I heard from dieselgman my stub shafts made it from England to Kansas and will be on the way to Buckley. What kind of pre lube do you like to use on the rod bearings?    South Prairie Larry

I have never worked on one of these engines, but when I was younger, I used to be in the fishing industry and had several diesel engines. I am not by any form or fashion a diesel mechanic, but I have replaced a few injectors. The first thing the shop always told me was to NEVER touch the end of the injector, not even lightly or it might mess up the injector.

Would an EXPERIENCED Lister mechanic please coment on this as to if this precaution should be followed with a lister?

[dieselgman]

Larry,

No rest for the wicked eh Larry? I think you have it made if you can keep as busy as yourself and be happy at doing it.

We use an engine assembly lube specially designed for bearings that we get from the auto parts store. Almost any lubricant would be OK though. The important thing is keeping it in place until the engine has developed its own oil pressure. We prefer the very heavy stuff that sticks and stays put. I think Hyper Lube is one brand name we have used and liked.

On the fuel injection question... internal parts of the injection system are of such a high precision that any contamination can cause sticking or failure. This includes skin salt/oils and this is the reason for the caution about handling the parts. The tips of the injectors are exposed to the combustion chamber gases and carbon etc. and generally can handle being touched but it is best to keep them protected during handling so that they are not damaged. New parts come with protective sleeves.

Best Regards,

Here I am again after more Christmas tree stuff and the regular jobs, and got the Road King out for a spin last Saturday, finely installed the new stub shafts and rocker arms tonight. Next on to the connecting rods to the crank.   South Prairie Larry

Friday night,  got the new cylinders,with connecting rods onto the crank, oil sump buttoned up, next job the heads. Larry

Monday night got the heads shimmed to .035 - .038 inches with the mash the lead solder with the piston set up routine and learned how to read my dads old 1940s micrometer.  Larry
