Lincoln F3LY-6268-A Timing Chain

To check the timing chain with the cover on, remove the battery cable and position the number one cylinder at TDC. Turn the crankshaft 360 degrees, place the timing indication before TDC, and remove the valve cover on the right side. Affix a dial indicator to measure chain slackening then rotate the crankshaft to TDC. If it shifted by more than 10 degrees, one must replace both sprockets and chains. While inspecting without a cover, get rid of all obstacles barring access to its top surface by pulling away accessories; then move this top part of the engine block with the number one piston on it towards TDC. Measure chain deflection after taking off the balancer and cover; if it is greater than 1/2 inch replace it with a new chain. Replace gears in case they are broken or damaged. Remove it when the number one piston is at TDC, open up the top part of the engine, align sprocket marks, and slide out this device together with all its parts including chains as well as sprockets.
