The 4.0 liter OHV engine ( over head valve ) does not use a jackshaft ( 1991 to 2000 )
but all the 4.0 liter SOHC engines have 3 timing chains and a jackshaft
Yamaha introduced the jackshaft system on their snowmobiles in 1974. This innovation was part of their effort to improve performance and reliability in their sleds. The jackshaft allowed for better power transfer from the engine to the drive system, enhancing overall efficiency.
I have a 1995 Ford Explorer : It has the 4.0 liter Over Head Valve / pushrod design VIN " X " engine It has cast iron cylinder heads and uses ( 1 ) timing chain The best word that I have heard to describe that engine is " gruff " but I like it . Although , depending on model year of Ford Explorer it is rated at 45 to 50 horsepower LESS ------------------------------------------------------------------------- The Ford 4.0 liter Single Over Head Cam , V6 engine has aluminum cylinder heads and uses ( 3 ) timing CHAINS . A main chain at the front of the engine to the " jackshaft " , a chain from the jackshaft to the front of the drivers side cylinder head , and a chain at the REAR of the engine from the jackshaft to the passenger side cylinder head . It is a smoother running engine and as mentioned before it has a higher horsepower rating Ford first started using that engine in certain models of the 1997 Explorer and as far as I know they have worked the " bugs out "
