12.7 series 60 inframe cost?

$6000-$10000...most likely $8000 or more

 

Have a blow by test done, if it falls in spec don't worry about it.

Assuming it's either a ddec 2, 3 or 4 for peace of mind I'd have the bull gear replaced, do an overhead, replace the turbo and oil pump relief valve.

Don't worry about the rods and mains they're almost bullet proof.

 

what do you think it will go for ?

 

If it needs an overhaul, it should sell for about $4,000 at auction tops!!! If you pay anymore for it then you are crazy unless it has brand new tires, brakes, transmission

 

The last time I checked on rebuilding a series 60 was about 12 or 14 years ago. Detroit wanted $8,500 at that time. I would expect to spend up to about $12,000, depending on what needs to be done. I have a friend who rebuilt his N14 Cummins about a year ago and he spent almost $10,000. It should cost about the same for a Detroit as it does for a Cummins. He didn't replace his injectors at that time. If you want to know for sure call a dealer who rebuilds them and ask what they will charge. You may find a smaller shop or mechanic who could do it for less. If you can do the work yourself then you can probably do it for about half of what it would cost for a Detroit certified dealer to do the work.

 

I would not worry too much about it as long as it is running good. You could drop the pan and check the lower bearings. You could put lower bearings in for about $800, as I recall. You may get the serial number off the engine and check with an authorized dealer or distributor and ask them to run the number. If the engine has had work done at an authorized dealer it should pull up the history and they can tell you what has been done.
