Hi all, I have a 1967 TD15BG serial 21210 with the original DT361 engine. Injector tip number DLL145S261 pump DDGFC637-54AJ turbo Solar TC3B Ive dome a lot of work with this unit and to this unit including renewing both steering clutches, right side planetary bearings, fuel pump overhaul and renewing and calibrating the injector nozzles and rebuilding the starter motor. She’s a real top machine and punches way above her weight. I’ve been working alongside a D6 Cat and holding my own. Question I have is regarding the amount of smoke I have. I did remove the fuel pump after the flex drive coupling broke and had it overhauled at a reputable fuel injection shop. Reinstalled it and all was good except after idling for a 5-10 minute period it starts to hunt a little (this was the same before the pump was done). Give it some throttle and it runs smooth again and away we go. So when I was doing the planetary bearings I pulled the injectors and sent them out to the same fuel shop to be overhauled. The nozzles fitted are DLL145S261 or p/n 0433270074 which I believe is IH p/n 610715C91. The fuel shop couldn’t source new nozzles so cleaned up the old ones and I reinstalled them. Same problem as before re idle. So I pulled the injectors and sent them out to a different shop who managed to source 5 new nozzles (different stamp number on the nozzle to original) and cleaned up the best old nozzle. I reinstalled, same problem but in addition a heap of black smoke when pushing hard. I pulled the injectors again and sent them back, they were checked and sent to me, I put them in and same result. I am really searching for a set of reman injectors with the nozzle number or 6 new nozzles I have mentioned above. Searching globally for them seems to be like looking for rocking horse pooh. Anyone out there got any leads on a set of 6? I need them tested before being sent out. Seems a lot of these components have been sitting for years and the needles have seized in the nozzles as the assembly lube has gone solid. Especially a problem with NOS. Many thanks

I have noticed that the top #1 main bearing is not flush with the block. It protrudes about .020. Is this ok? The bottom bearing is flush. The bearings were all the same stock number, so I don't think I would have gotten them out of place. Should the top bearing be a different stock number?

Can anyone tell me the thickness of the head gasket against the sleeve on a DT361 engine? Want to make sure I received the correct head gasket.
