Can anyone tell me or show me where is the timing mark for the D1? I can see the timing mark in the crankcase pulley, but I cannot locate the reference point in the engine. I checked through the manual and I couldn't find it.
If possible, can someone post a picture?
Thanks,
Vincent |

I'm assuming you have the 3.9 "B" suffix motor with a distributor:
There is an approximately 1/2-inch rounded metal peg sticking out from the front of engine front cover just above the crankshaft pulley. You'll notice that the peg is part of the front cover casting, but has been ground down on top at an angle to make a flat surface which aligns with the timing marks on the crankshaft pulley.
The best way to see this is to stand in front of the truck and look down at the crankshaft pulley between the power steering pump pulley and the water pump pulley. You'll see the flattened peg over the crankshaft pulley, which is where you aim your timing light.

Make sure that you take the reading whilst positioned above the timing peg. I found it easiest to see the marks and the peg from side of the car but then parallax causes you to be off by a good number of degrees.
Also, factory spec. is 6 degrees. We found that here at altitude of 6000 feet, setting the timing to about 10 to 12 degrees made a huge difference in performance and response. We used 93 octane fuel.

Also Vincent, disconnect the vacuum advance line whilst doing the timing.
Rover recommends that you all block off the stepper to plenum chamber hose. I do this by clamping it tight with a vice grip. Start the engine and check that the Base idle speed is correct, it will be around 500-550 rpms I think ( but check specs) then adjust the timing. Release the hose clamp, this will also set your stepper in range |
