160 lbft This is important since the balancer is a "slip fit" not a "press fit" as many engines have. Failure to torque it suffiently will result in wobble and eventual balance failure.
With a harmonic balancer puller.
To set the timing marks on a 1969 Pontiac LeMans, first ensure the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. Locate the timing tab on the timing cover and the harmonic balancer; the timing marks are usually indicated on the balancer. Align the mark on the harmonic balancer with the desired timing specification indicated on the timing tab. Adjust the distributor as necessary to achieve the correct timing setting.
We need to know what engine your talking about.
Depends on which engine the car has...
30 degrees
all oil pans go to 10 ft lbs.
21st August 1969
The setting is in Harlem, New York in the early 1970's, perhaps even 1969-1971 would be my hunch.
220 lb-ft, plus however much more torque it takes to align one of the castellations in the nut with the cotter pin hole in the axle. If that pin is not in place, your back wheel will fall off.
There is no lash adjustment on Pontiac engines. You simply torque the nuts down to 20 foot lbs.
Just tighten them down as tight as you can and then drive the car a few miles and retighten the bolts again as they will be loose after the gaskets heat up.
cam timing marks are on the timing gears inside the timing case cover the crank timing gears are located on the harmonic balance (big pulley wheel at bottom of engine on front of crank)
