    I can’t figure out exactly which n14 I have and what torque specs I use when doing an in frame?
    I know it’s not a STC, I have an ECM.
    S/N 11868318
    CPL-2025.

    my book is for stc, celect and celect plus models. I’m pretty sure mine is just the n14 so what torque specs do I use?

    You have a N14 Celect plus built in 1997 so should use all the latest torque specs. Other than the main bolt torque, that has a break at serial# 11875596 so for that you use the older block torque specs. (final main bolt torque of 255 ft-lb)

    You can also make a free account on cummins quickserve to get access to the latest online manual for your engine. (free account allows up to 5 serial numbers) Cummins QuickServe Online

    I hate to ask, but can someone look up ser# 11994122? I can’t find anywhere to look it up. Any help would be greatly appreciated.
