timing chain setup for 93 3.9 dakota

From : horizon a

Q: i am replacing the chain and gears. since the chain jumped i have to set up the cam and crank. when i put the new gear on the cam and rotate the timing mark to the 6 oclock position the distributor rotor points to the #4 cylinder. is this correct. if so i then have to find compression stroke for the #4 cylinder to line up the dot in the 12 oclock position on the crank gear. am i on or not. i have worked on chevy engines which are on cylinder #1. have never worked on the 3.9. appreciate any help. john .

possible distributer drive gear bushing failure causing drive gear to push distributer up and jumped a tooth or two. at top dead #1 with the distibutor out the drive gear slot should line up with the most forward intake manifold bolt on the left side cly #1. kinda hard to see with the intake in the way. does the distributor turn with the cam gear good luck bryan i am replacing the chain and gears. since the chain jumped i have to set up the cam and crank. when i put the new gear on the cam and rotate the timing mark to the 6 oclock position the distributor rotor points to the #4 cylinder. is this correct. if so i then have to find compression stroke for the #4 cylinder to line up the dot in the 12 oclock position on the crank gear. am i on or not. i have worked on chevy engines which are on cylinder #1. have never worked on the 3.9. appreciate any help. john .

bryan thanks for the response. the distributor does turn when i rotate the cam. when i reference the haynes for chain replacement it refers to tdc the #4 cylinder. the mitchell books reference the #1 tdc. this is the confusion. if haynes is correct then i am on track. if mitchell is correct i am really confused. have you done a v6 timing chain. according to some they are different. thanks john .
