Fzj80 oil drive gear (on crankshaft) orientation (1 Viewer)

[ceylonfj40nut]

I am in the process of replacing my headgasket and timing chain. Need to know which way to put the oil drive gear back on the crankshaft. One side is flush, the other side has a little lip that protrudes off the gear. Does flush side seat against engine or face radiator?

I'm looking at the `96 FSM and the flange goes toward the radiator and away from the engine.

I have the FSM but did not see it. It just shows the timing gear orientation only. By flange do you mean the lip that protrudes out?

Looking at the FSM there are only two "gears" shown to be installed. The PUMP DRIVE SHAFT GEAR, and the OIL PUMP DRIVE SHAFT GEAR. The pump drive shaft gear goes on the crankshaft, and the oil pump drive shaft gear goes in between the pump drive shaft gear and the power steering pump gear (already installed). The teeth on the pump drive shaft gear are running left to right when installed, and the teeth on the oil pump drive shaft gear is running right to left when installed. When all three gears are installed they will only go in one way (the teeth must mesh to drive the oil pump and power steering pump).

Awesome. Makes sense. Thanks!!!
