ABSTRACT:
A cylinder head is removed from an overhead cam engine by first inserting a timing chain support tool between opposed portions of the timing chain so that opposite edges of the tool support the chain above the crankshaft sprocket. A movable finger at the bottom of the tool can be moved outwardly to apply pressure against the normal bias of the chain tensioner, which prevents the timing chain from slipping off the crankshaft sprocket while the upper cam shaft sprocket and the cylinder head are removed. The engine can be cranked with the cylinder head removed by mounting a cam shaft idler tool on the engine block for supporting the cam shaft sprocket. The timing chain is engaged with the cam shaft sprocket and a slide member of the idler tool can move the cam shaft sprocket until it applies tension to the timing chain. The movable finger which opposes the timing chain tensioner can be actuated to release pressure on the tensioner so that the tensioner can engage the timing chain, allowing the engine can be cranked.
