Windsor Engine

CAUTION: Since the engine is not free-wheeling, if the crankshaft (6303) or the camshafts (6250) are moved in any manner during removal and installation the crankshaft and camshafts must be re-synchronized.

CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: Unless otherwise instructed, at no time when the timing chains an removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.




If the copper links are not visible, mark one link on one end and one link on the other end, and use as timing marks.




- LH camshaft timing mark is approximately at 12 o'clock.
- RH camshaft timing mark is approximately at 11 o'clock.




Install the crankshaft sprocket, make sure the flange faces forward.




Position the lower end of the (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.




LH timing chain on the camshaft sprocket with the camshaft sprocket timing mark positioned between the two copper (marked) chain links.




Position the RH (outer) timing chain on the crankshaft sprocket.





RH timing chain on the camshaft sprocket with the camshaft sprocket timing mark is positioned between the two copper (marked) chain links.





Verify correct alignment of all timing marks.
