I was reviewing adjusting push rods in the 80-83 FLT/FXR service manual. The procedure says " move the front piston until it is at the top of it's compression stroke". It then states " with the front piston this position the Advanced timing mark will align with the timing inspection hole." WTF If the front piston is at the top of the compression stroke wouldn't the TDC mark be aligned with the timing inspection hole. Have I lost my mind??

 

Plugs out rear wheel up in 4 th gear - pushrod covers open - rotate the engine til one of the intake push rod is at full lift - then adjust the other intake

do the same thing exhaust one at full adjust the other then rotate till the other is at full lift and adjust the other

 

+1. That is how I have always done it. When one is all the way up and the other is all the way down. Boom. You got it.

 

solids or hydraulics?

 

Good point. You going to be opening a whole new can of worms there. Thanks for that. Spin for feel on the low point. dammit man.

 

Thanks guys, Hydraulic, I do understand the principle but I was scratching my head when I read in the HD manual that when the front piston is at TDC the advanced mark will be i the hole.....misprint or what?

Here's what I find easy. Rotate the motor until one of the cylinders is in overlap, the other cylinder is now on the base circle,
There are many ways to do this and I understand that the adjustment must be done on the lowest point of the cam and let it bleed down before attempting to rotate the motor or bad things will happen.

FWIW ive found the best method for hydraulics is the pull them out and clean them out method........then buy one of those hydraulic lifter clearance check tools so next time you only have to check them
