torn down, cleaned and ready to reassemble

the shaft was left in, I had no new seal or bearing or roll pin so I left the shaft alone

cover plate for the oil seal held on with 2 small machine screws, there is also a washer slid onto the shaft -don't forget this washer

this is the breaker assembly, also called the stator & it has a ring at the base. 2 small machine screws w/washers attached hold that ring in place

pickup coil & frame. The 2 small white tabs on the right are where you check the resistance. 920-1120ohms is the range you need have

These 2 parts plug into each other & are held into the dist. with 2 machine screws. If these are hard to remove use vice grips & do it slow & careful

stator fastened in. Put a thin coat heavy grease on center shaft. The governor rotates on this shaft and must move freely

pickup coil fastened

Governor plate w/o weights attached. Note position of flat side of shaft in reference to the tabs on the plate -flat side to the larger tab

flat side of shaft to the larger tab, this is the tab the rotor screws to

thin film heavy grease on the posts the weights move on

retaining clips hold weights on posts and springs hooked over posts

Turn your crankshaft until the timing mark on the crank pulley is at the center line on the timing cover, this is TDC.  The crank will turn two full rotations for one rotation of the cam.  You need to get the TDC marks lined up so that the dowel pin in the cam is at the TOP.  Actually it will be slightly counter clockwise of 12 o'clock.  TDC never lines up with the dowel at 12 o'clock.  If you do not have the valve cover off and you didn't put the motor to TDC with the rotor pointing to #1 position then you do not have to remove the valve cover.  The easy way to tell if you are in the correct cycle is to remove #1 spark plug and have someone bump the starter, when you feel pressure building, STOP then continue to the TDC mark on the timing cover and that will place you in the correct cycle to insert the distributor.  There is a small machined dot near the roll pin that holds the drive gear to the shaft.  Line that up with the raised notch on the dist. stub.  Doing this will put the rotor clockwise of the #1 position.  Now put the stud that is in the head in the center of the adjustment range of the dist.  Slowly push the dist. into the head and do not rotate it when doing so.  When you get it right, the rotor contact will line up with a raised bump on the dist. base and the stud in the head will stay in the center of the adj. range.

CAM WITH DOWEL AT THE TOP WHEN THE CRANK PULLEY IS AT TDC

DIST. WITH STUD IN CENTER OF ADJ. RANGE -NOTE POSITION OF ROTOR

MACHINED DOT ON DIST. SHAFT LINED UP WITH RAISED NOTCH

NOW SLOWLY INSERT THE DIST. INTO THE HEAD WITHOUT ROTATING THE DIST. OR TOUCHING THE ROTOR, line the notch on the adj. slot with the stud before and as you insert

ROTOR TAB SHOULD LINE UP WITH RAISED BUMP ON DIST. BASE

THE MACHINE DOT WILL ROTATE TO THIS POSITION
