I was told that a 1969 Diamond T with a 335 is coming in for a overhead. A little bit before I started wrenching so I thought I check some of the more experienced techs on the over head setting. Been a long time but I have set small cam with the dial indicator setting the travel I think was .170 and still have the tool.

Thanks Brent

If memory is correct......the NTC335 valve setting was 0.014 intake....0.027 exhaust with a go-no go feeler gauge, and 48 - 52 inch pounds on the injectors at the bottom of travel, all cold settings. When you do the injectors, you crank them down to 60 inch pounds, back them off 3/4 turn and 60 inch pounds a second time to push out any fuel in the injector and oil under the push rods, then back them off 3/4 turn and then down to 48 - 52 inch pounds and end it there.
Some of the later injectors were 60 inch pounds and even some were 72 inch pounds. Top-stop was a different story, but I don't believe your 1969 335 has top stop in it or the later injectors.

Back in the day, when the NTC335 came out....nothing could touch it until the NTC 350 made it's appearance a few years later.....aaaah the memories..

Thanks Joe. I haven't seen the truck yet. I didn't think it have top stop. The back side of the cam would be like the N14 method . Valves and injectors on the same cylinder? I remember using the indicators on some small cams but never did the inch pounds till the STC switch to that method.

Thanks Brent

I have tried different methods, but never noticed a difference. Those old Cummins didn't need much attention. Close enough was good enough....they ran well even if the settings were off considerably. I have just found it easier to use the inch pound method to work as well as anything in a lot less time. It is a bit more impressive if the customer is standing by to see a dial indicator being used.
