RD6 head bolt torque and serial number locations

Ser # on the left side of the eng block & the left rear transmission case. The square heads raise individual injection pump lifters to check spray manually. If the unit has been setting a long time, make sure the lifter is free or you will break the weak aluminum lifter casting.

You need the earlier parts book for 2H1 to 2H3247 which use the flange type injector pumps.

Use the head bolt torque for the D13000 (one head instead of two) for the D6600.

Thank you for your reply. I will look for an earlier book. I am glad you have the information about the head. I had the head off 20 years ago to repair a valve seat and I do not recall where I got the torque values, but it was from a parts source because at that time.

I have owned this tractor for 20 years. I bought it sitting in a field in 1996 from the second owner and he retired it in 1982. I found the original owner and he told me how to start it and he retired it in 1952.
I bought it because I needed it to build my house and because I love anything antique with a gas engine on it.

Thank you for sharing your knowledge.
I will check back tomorrow.

Hi , The serial # on the engine is behind the water pump on the diesel

Thank you for the reply.
I never even tried cleaning that area to look for it, but finally I have a serial number 2H2493 to work from.
Thank you.

I may start disassembly next weekend if I can. I wish I could pull the piston out from the bottom and look up in there to see where the water is coming from. I found a different topic where someone mentioned the pre-combustion chambers may get water leaks.

Pre-com chambers would be the first place to look, followed by low liner height, cracked head or block then pitted liner.

Thank you for the reply.
If a pre combustion chamber leaks, can I see that by pulling the injector?
Thanks,

Good evening,
I finally removed the head and it is leaking around the outside of the valve seat repair I had done 20 years ago. I plugged the holes and filled the head with water to find it. The repair was done by flame spray. I doubt it is repairable.

Does anyone know who would have a good head for sale that would ship to Oklahoma at my expense of course? I sure would appreciate it.
Please let me know.
Thanks,
Scooter
