Which drive pulley? If you are referring to the engine drive pulley, I'd drain the primary and remove the outer primary and check the compensator sprocket. Check the nut on the compensator. I would tell you what the torque rating is but I don't know what year model bike we're talking here. Please advise me of where the noise is coming from and the model of bike we're working on.

Good Luck
Steve

Jeep 360 rattle sound at idle in park


it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

Rocker arm torque specs on a 97 gmc jimmy 4.3


  1. For the 4.3L engines which are equipped with screw-in type rocker arm studs with positive stop shoulders, tighten the rocker arm adjusting nuts against the stop shoulders to 20 ft. lbs. (27 Nm) on 1994-96 models and 18 ft. lbs. (25 Nm) on 1997-99 models. No further adjustment is necessary, or possible.
  2. For most 4.3L engines which are not equipped with screw-in type rocker arm studs and positive stop shoulders, properly adjust the valve lash. For details on valve lash adjustment, please refer to the procedure in Routine Maintenance . (see below)
4.3L Engine

The 4.3L engines may be equipped with either of 2 rocker arm retaining systems. If your engine utilizes screw-in type rocker arm studs with positive stop shoulders, no valve lash adjustment is necessary or possible. If however, you engine utilizes the pressed-in rocker arm studs, use the following procedure to tighten the rocker arm nuts and properly center the pushrod on the hydraulic lifter:
  1. To prepare the engine for valve adjustment, rotate the crankshaft until the mark on the damper pulley aligns with the 0? mark on the timing plate and the No. 1 cylinder is on the compression stroke. You will know when the No. 1 piston is on it's compression stroke because both the intake and exhaust valves will remain closed as the crankshaft damper mark approaches the timing scale.

Another method to tell when the piston is coming up on the compression stroke is by removing the spark plug and placing your thumb over the hole, you will feel the air being forced out of the spark plug hole. Stop turning the crankshaft when the TDC timing mark on the crankshaft pulley is directly aligned with the timing mark pointer or the zero mark on the scale.
The valve arrangement is as follows:



E-I-I-E-I-E (right bank-front-to-rear) E-I-E-I-I-E (left bank-front-to-rear)

  1. With the engine on the compression stroke, adjust the exhaust valves of cylinders No. 1, 5 & 6 and the intake valves of cylinders No. 1, 2 & 3 by performing the following procedures:
    1. Back out the adjusting nut until lash can be felt at the pushrod.
    2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
    3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turns.

  2. Rotate the crankshaft one complete revolution and align the mark on the damper pulley with the 0? mark on the timing plate; the engine is now positioned on the No. 4 firing position. This time the No. 4 cylinder valves remain closed as the timing mark approaches the scale. Adjust the exhaust valves of cylinders No. 2, 3 & 4 and the intake valves of cylinders No. 4, 5 & 6, by performing the following procedures:
    1. Back out the adjusting nut until lash can be felt at the pushrod.
    2. While rotating the pushrod, turn the adjusting nut inward until all of the lash is removed.
    3. When the play has disappeared, turn the adjusting nut inward 1 3 / 4 additional turn.

Overhead valves making noise like they need ajusting


Valve Lash ADJUSTMENT 1.6L Engines NOTE: Measure valve clearance with the engine cold.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the valve cover.
  3. Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
  4. Check the valve clearance. The valve clearance specifications are as follows:
    • Intake valves: 0.005-0.007 inches (0.13-0.17mm)
    • Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
  5. After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
  6. Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible. prev.gif next.gif

Very noisy engine at idle Rattles like cam chain. Noise goes away as you rev the engine. What do you think it could be?


Could be the carbs are out of balance as this will cause lash noise at the primary drive gears as these are straight cut gears.

Engine rattle


Does it only do it with the a/c on or does it do it with it off and in gear. If it does it with the air off and in gear the the problem is possibly in the tranny. If it only does it with the air on the possibly another pully in a bind causing the rattle possibly water pump.
