Cummins 6CTA8.3 Injection Timing
Just a taper, no key or splines. You'll also need some timing tape or you can print your own here. I think the pulley is 8.75? diameter which is 225.25 mm. https://www.blocklayer.com/timing-tape.aspx- MAdams

Cummins 6CTA8.3 Injection Timing
The gear is bigger than the hole. All you can do is use a gear puller to remove the gear from the taper but not remove the gear from the housing, or loosed the IP mounting nuts and knock the IP back a 1/2" or so.- MAdams

Cummins 6CTA8.3 Injection Timing
I'm trying to wrap my head around this and an stuck. A few months ago I attempted to advance the IP timing 6 more degrees(14 total) but after I was done I kept wondering if I retarded the timing by mistake. After driving the truck I didn't notice any more power and my EGT's seem high, like 900...- MAdams
