Rocker arm specs


ROCKER ARM SUPPORT PLATE
Installing the rocker arms and rotating the engine with the valve
train loaded can result in bent push rods, damaged bushings
or a warped support plate.

To install the rocker arm support plate, both lifters of the
cylinder being serviced must be on the base circle (or
lowest position) of the cam.
Place the rocker arm support plate assembly into the rocker housing. Loosely install the four
rocker arm support plate bolts with flat washers.
Tighten the rocker arm support plate bolts in a cross pattern and alternately tighten
each of the four rocker arm support plate bolts just 1/4 turn. THEN continue turning the bolts in these increments until snug. THEN following the same sequence, tighten the bolts to 18-
22 ft-lbs (24.4-29.8 Nm).

THEN install and alternately tighten the two bolts to secure breather assembly to 90-120 in-lbs (10.2-13.6 Nm).

Installed new oil pump and now have broken rocker arms


THe rocker arms are broken because there was not enough downward movement in the valves to allow the cam to complete its turn. IT happens when the valve spring retainer either hits the top of the valve guide or the valve springs are fully compressed forming a solid block . If you have hydraulic valve adjusters I would be suspicious of a lack of movement (seized) in the ones that broke the rocker arms

I have a loud tapping in my front rocker box on my 2000 harley 1200 sportster custom i have pulled top and middle covers but the valve springs look fine and pushrods seem fine an thoughts?


I could be the bushings in the rocker arms and the rocker arm shafts. Bring the piston to top dead center on the cylinder that has the noise. Both valves should be closed. Allow about five minutes for the tappets to bleed down on that cylinder. When you can spin both of the pushrods with your fingers, remove the 5/16 inch bolts on the right hand side (pushrod side) of the head. This should allow you to push the rocker arm shaft out and remove the rocker arm. You may have to gently tap the rocker arm shafts out but it should not be difficult to get them out. Do not mix the rocker arms and their shafts up. Keep them together. Check the bushings in the rocker arms and the rocker arm shafts for wear. The bushings can be replaced and use new rocker arm shafts if this turns out out to be the problem. Check the face of the rocker arm where it pushes down on the valve stem for wear as well.

P 2647"A" Rocker Arm Actuator


Your going to need a air pressure regulator or better yet if the ECM found fault price it and replace it
  1. Start the engine, and let it run for 5 minutes, then turn the ignition switch to LOCK (0).
  2. Remove the cylinder head cover.
  3. Set the No. 1 piston at top dead center (TDC).
  4. Move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A should move independently of the secondary rocker arm B.
    1. If the intake secondary rocker arm A moves freely, go to step 5.
    2. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, then check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.
    3. Repeat step 4 on the remaining intake secondary rocker arms with each piston at TDC. When all the secondary rocker arms pass the test, go to step 6.
    4. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa (4.0 kgf/cm2, 57 psi).
    5. Inspect the valve clearance.
    6. Install a 10 x 1.0 mm adapter to the inspection hole, then connect the air pressure regulator
  5. With the specified air pressure applied, move the intake secondary rocker arm A for the No. 1 cylinder. The secondary rocker arm A and secondary rocker arm B should move together. If the intake secondary rocker arm A does not move, remove the secondary rocker arms as an assembly, and check that the pistons in the secondary rocker arms move smoothly. If any rocker arm needs replacing, replace the secondary rocker arms as an assembly, then retest.

Rocker arm come out on jeep chrysler 3.7 eng


A rocker arm is the arm that sits on top of the valve stem and connects to the push rods 'the push rods sit on the cam so when engine is running, the push rods go up and down in a timed sequence and with the rocker arms, open and close the inlet and exhaust valves. the rocker arm is located inside the valve(rocker)cover .If the rocker arm gets loose or comes out.
Check the nuts on the shaft which holds the rocker arms.either the shaft or nuts are got loose.They need to be tightened.Don't make it too tight or too loose.  Too tight,and they don't flutter right. Too loose,and they allow the rocker arms to wiggle out of whack. Other possibility can be  something is broken, bent, collapsed, or out of adjustment. 
Thanks. you can rate this solution and show your appreciation.

Cam gears pulled out when changing gear box gasket trouble reinstalling due to tappets line cams up but front exhaust to tight to install


I'd be interested in knowing how the cam chest cover cam off changing a gear box gasket but.

In order to get the cams back in and to insure their proper timing, I'd put the rocker arms out. I'd pull them all out but you're free to do whatever you wish. Remove the top and middle rocker cover on the front clinder. Remove the large bolt that hold the lower plate and the rocker arm for the front cylinder in. Tap the rocker arm shaft out of the rocker arm and remove the rocker arm. You can then get your cam into position. Now, to get rocker shaft back in, rotate the engine until the front exhaust cam has the valve in it's closed position. Reinstall the rocker arm and shaft and torque the bolt to 25 foot pounds. Reassemble the upper and middle rocker box covers.

Loud rattle noise in Camshaft


First, your engine has rocker arms, if you have a 4 cylinder you have 8 rocker arms, and if it is a 6 cylinder you have 12 rocker arms. Now if it is indeed a rocker arm making the noise, the cause is most likely a bad lifter or a worn cam shaft.
