What should torque be on roller rocker arms?

What should torque be on roller rocker arms?

Slowly torque the bolt to 18-20 FT-LBS. Since you are pushing down the plunger in the hydraulic lifter as you torque the bolt, it will probably take a minute or two to complete the procedure. The bolt should have turned between one-quarter to one full turn to reach the torque setting. This will give the correct lifter preload of .020″ to .060″.

What does the rocker arm do in an engine?

An engine’s rocker arm is a reciprocating lever that transfers radial movement to open the poppet valve, a valve responsible for opening and closing the intake and exhaust ports in the engine’s cylinder heads. The rotating lobes of the camshaft raise and lower one end of the rocker arm while the other end acts upon the poppet valve stem.

Can a cylinder head be modified for rocker arm studs?

Pedestal type cylinder heads can be modified for rocker arm studs (351C illustrated). Machine at right angles to the existing stud hole/bolt hole, not the bottom of the head. The valves in canted valve heads operate at compound angles. For 302/351W cylinder heads, measure from the top of the pedestal.

What are torque specifications?

Torque specifications are for dry threads only. The fastener threads should be free of oil, dirt, grit, corrosion, etc. The hardware should turn freely without binding when tightened by hand. It is important NOT to lubricate hardware threads or seats. The friction at which torque is measured against should come from the hardware seats.

What are the torque specs for valve cover bolts?

Proper torque for the valve cover bolts is between 50-100 in-lbs., which is about 8 ft-lbs for a maximum. If you have the gasket properly set, and proper torque on the valve cover bolts, you should not leak.

What is the head bolt torque?

Head Bolt Torque Head bolt torque refers to the amount of rotational force that must be applied to the cylinder head bolts for a safe and secure connection either to the engine block or another cylinder head depending upon the engine. After the desired torque is reached, some bolts then require further rotation of a few degrees.
