OK, thanks for the help so far, now I have one more question if someone can answer. I need to know the head bolt torque setting for this motor? anyone know?
Clint
From the 955 60A1-up Service Manual for the D330T
OK, If some one can help. I need the head bolt torque settings again, Please
The water pump went out and after rebuilding it, I have water blowing out from around the injector and getting in the cylinder. Is this more than likely the gaskets or just a seal around the injector chamber?

first round on the head bolts 85 foot pounds
second round 120-130 foot pounds
The pattern of tightening is starting at the center and doing all of the two middle rows of bolts in a criss-cross pattern down the head and then returning to the center and doing the outside two rows in a criss-cross pattern.
The water blowing up around the injector and getting in the cylinder could be a combination of problems, but the one problem that could cause that would most likely be if the precombustion chamber itself has a hole in it. It will have to be removed to change the seals anyway, so check it good for pits while you have it out. Could also have a cracked head or blown gasket and some bad o-rings on the top of the precombustion chamber.
Hope it isn't too bad. The precombustion chambers probably aren't too expensive (aftermarket).
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

Hold on here a minute Drigger. Does your engine have a cast aluminium valve cover or a pressed steel one? Aluminium is on a D330 and pressed steel is on a D330C. Different engine different torques. Also the 330 has a belt driven water pump 330C has a gear driven one. OM has a file of pic to identify your engine. 85J is also a common serial #.

Hi Bob,
A check of my TRW parts interchange indicates the 955K serials # 61H1-61H1801 uses the 330A turbocharged engine (early) same as the 60A1 series. Still a bit tricky identifying the 330TA, 330TC and 3304 engines across the K & L series:D

Still had em on file:D . CCJersey seems to have the symptoms covered.
Thanks to all, a fe wmonths ago I got this same info from you, but have since had a couple of puter crashes, I have the info saved on CD, but cant find it, to many dang CD's.
I pulled the head today, the head looks OK, the gaskets looks fine, so its looking like it is the injector chamber seal, I hope?
any know the best way to remove it?
or should I run it down to the cat dealer and let them get it out and put a seal back

The gaskets look fine, and these head bolts are the hardened bolts so will take the higher torque settings.
another quick question, once I get the engine running again, and the head bolts torqued, how long should I run it and re-torque them? or abou how many hours?
I replaced the hed gasket back in January, and torqued them to 160 # but when we pulled it today, they seemed easy to break loose, just a regular breaker bar did it, does that sound normal? I figured that I would have needed to use a cheater?
