How big is the rocker torque on a Ford Ranger?
With the number two piston top dead center, torque the number one intake, number two exhaust, number four intake and number five exhaust valve fulcrum bolts to 19 foot-pounds. Justin Chacos is a professional mechanic with experience on all vehicle types, from cars to boats to airplanes.
Why is rocker torque important in a 3.0 liter V6?
Given the fast operating speed of the camshaft, precise rocker arm maintenance is crucial to the operation of the 3.0 liter V6 engine. A moderate level of mechanical experience is necessary when performing this adjustment. Proper rocker arm torque is essential to safe engine operation.
Why do you need to torque the rocker arm?
Proper rocker arm torque is essential to safe engine operation. Every hardware item in an internal combustion engine must be torqued. Proper torqueing prevents the hardware from working its way loose, damaging the rocker arm from excessive torque or allowing the rocker arm to shift during operation. Torque each fulcrum bolt to 8 foot-pounds.

What are the valve clearances on a Ford Ranger?
Adjust the valve clearances A with the No. 1 cylinder at TDC of compression, and those of B with the No. 4 cylinder at TDC of compression. Valve clearance [Engine cold] IN: 0.10—0.16 mm {0.0040—0.0062 in} EX: 0.17—0.23 mm {0.0067—0.0090 in}. Tightening torque (lock nut) 20—24 Nm {2.1—2.4 kgf·m, 15—17 ft·lbf}.
What happens when you loosen the locknut on a Ford Ranger?
CAUTION: Loosening the locknut and the adjust screw while the cam lobe is not pressing down the rocker arm will damage the claw of the rocker arm. When loosening the locknut and the adjust screw, rotate the crankshaft clockwise and be sure that the cam lobe presses down the rocker arm firmly as shown in the figure.
How to remove stock rocker arms on m-6564?
Step 1:Remove valve covers. Rotate engine to number 1 cylinder TDC. The distributor rotor should be at the number 1 terminal. Step 2:Remove stock rocker arms, fulcrums and bolts from number 1 cylinder. Clean pedestal mounting surface. Remove pushrods; clean, oil and reinstall. Make sure the pushrod is in the lifter seat.
Where are the lifters on a Ford Ranger?
Just by removing the valve cover you can see the gap between the top of the valve and the rocker arm. That was the worst of the lifters. It had completely collapsed inside. This is just a reference shot.
Can a lower intake manifold be removed from a Ford Ranger?
Lower intake manifold removed along with both rocker arm shaft assemblies and push rods. Now in plain sight it becomes clear that the lifters will definitely not come out with the heads in place.

Torque to 20 ft. Lbs. bandit_60 You can, t adjust hydraulic valve lifters! You put the rocker on the low cam ( all the way down ) and torque the rocker nut!
How much torque do you need for a rocker arm?
Proper torqueing prevents the hardware from working its way loose, damaging the rocker arm from excessive torque or allowing the rocker arm to shift during operation. Torque each fulcrum bolt to 8 foot-pounds. If your foot-pound torque wrench does not adjust to 8 foot-pounds, torque to 96 inch-pounds with an inch-pound wrench.
