A friend asked me to find this information.
He is looking for the valve spring specs on the 4.0 SOHC engine.
open spring rate
closed spring rate
install height
coil bind
and the exterior dimensions on the spring itself .
so far we have only got this information
Valve spring free length 43.1 mm (1.7 in)
Valve spring squareness ± 1.5 deg
Valve spring compression pressure at specified height (lbs) 275-305 Nm at 35.9-36.7 mm (202.84-224.968 lb-ft at 1.413-1.445 in)
Valve spring installed height 39.86-40.86 mm (1.569-1.609 in)
Valve spring installed pressure 320 newtons (72 lb)
can anyone fill in the other parts?
thanks!
