Crank spins a little less freely after torquing primary gear
Hi all,
Still busy with my 3AJ project.
I replaced all the bearings, put new 4th and 5th gear and sent the crank to be balanced.
This month I put the crank halves back together and installed the primary gear, crank balancer gear, oil pump and clutch hub.
At this point, the crank moves pretty much effortlessly. It falls and rotates under its own weight.
However this week, after torquing up the primary gear nut to 120nm I've noticed the crank doesn't move as effortlessly as before.
It doesn't bind or grind. It feels smooth and there are no weird sounds. However it doesn't fall under its own weight anymore. When I stop turning the crank, it doesn't move back & forth anymore.. it just stops (if that makes any sense).
It's still relatively easy to turn (although slightly harder than before), I can crank it with 2 fingers by rotating the clutch hub no problem.
Is this normal? I checked for clearance between the bearing and crank and everything seems fine.
I didn't forget any spacers (triple checked).
Thanks!
