Designed for use on Ford 1993-2012 4.2L, 4.6L 2-valve, 4.6L 4-valve, 5.4L V8, and 6.8L V10 engines when installing timing chains.
These engines are not free wheeling, and if an engine has "jumped time," it is possible the cylinder heads have to be removed because of damage to the valves or pistons.
Easily installs over the crankshaft and engine front cover alignment dowel to position the crankshaft at top-dead-center - the correct position for timing chain installation. OTC recommends the No. 6024 be used with Nos. 6009 and 6020 (but it is not required).
