If a feeler gauge won't fit between the valve adjustment and the screw is fully backed out, it's possible that the valve clearance is incorrect or there may be an issue with the valve train components. Try rotating the engine to a different position and rechecking the valve clearance. If the issue persists, it may require further inspection or adjustment by a qualified mechanic.

What is the distributor contact breaker point setting on a 1961 Holden?

not that critical 0.8mm or if you dont have feeler guages the back side of a hacksaw blade will do ( the side without the teeth) the standard contact breaker gap is 0.12mm - 0.13mm rotate the rota so the points are fully open then insert the feeler gauge realese the locking screw so that it shuts on the feeler gauge then lock the screw off (just nip tight as it can break real easy)then remove the feeler gauge then your done. i know this as i have done so many.


How do you run overhead on a c12 cat engine?

Finding TDCRemove two bolts (1) and remove cover (2) from flywheel housing (3) in order to open the turning hole.Put one 6V-5219 Bolt (1) in the timing hole. The timing hole is located approximately 127 to 152 mm (5.0 to 6.0 inch) above the turning hole in the flywheel housing. Use the 9S-9082Engine Turning Tool and a 1U-7115 Reverse Ratchet to turn the engine flywheel. Turn the flywheel in the direction of engine rotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel end. Turn the flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is reverse of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal rotation until the timing bolt engages with the threaded hole. This procedure removes the play from the gears when the No. 1 piston is at the top center position.Remove the front valve mechanism cover from the engine.The inlet and exhaust valves for the No. 1 cylinder are fully closed if No. 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Note: When the actual stroke position is identified, and the other stroke position is needed, remove the timing bolt from the flywheel. Then turn the flywheel by 360 degrees in the direction of normal engine rotation and reinstall the timing bolt.Injector adjustmentTo make an adjustment to the unit injectors on cylinders 3, 5, and 6 use the following procedure:Put the number 1 piston at the top center position on the compression stroke. Refer to Systems Operation/Testing and Adjusting, "Finding Top Center Position For No. 1 Piston".Turn the unit injector adjusting screw (2) clockwise until contact is made with the unit injector.Turn the unit injector adjusting screw through 180 degrees in a clockwise direction.Hold the adjusting screw in this position and tighten the locknut (3) to a torque of 55 ± 10 N·m (41.0 ± 7.0 lb ft).To make an adjustment to the unit injectors on cylinders 1, 2, and 4, remove the timing bolt. Turn the flywheel by 360 degrees in the direction of the engine's rotation. The engine rotates in a counterclockwise manner. This will put the number 1 piston at the top center position on the exhaust stroke.Repeat 2 through 4.Remove the timing bolt from the flywheel after all of the unit injector adjustments have been made.

How do I perform the SRAM B-gap adjustment on my bike's derailleur?

To perform the SRAM B-gap adjustment on your bike's derailleur, follow these steps: Shift the chain to the smallest chainring and smallest cog. Loosen the B-tension screw on the derailleur to create more space between the upper jockey wheel and the smallest cog. Adjust the B-gap by turning the B-tension screw clockwise to decrease the gap or counterclockwise to increase it. Check the gap by eye or use a feeler gauge to ensure it is within the recommended range. Tighten the B-tension screw once the gap is set correctly. Remember to test the shifting performance after making the adjustment to ensure smooth operation.


How do you adjust the valve clearance on Chevy Metro 1998 4 cylinders were to use the feeler gauge?

To adjust the valve clearance on a 1998 Chevy Metro with a 4-cylinder engine, first, ensure the engine is cold and remove the valve cover. Rotate the crankshaft to align the timing mark to TDC (top dead center) on the compression stroke for the cylinder you’re adjusting. Use a feeler gauge to check the clearance between the rocker arm and the valve stem; it should be within the specified range (usually around 0.008 inches for intake and 0.010 inches for exhaust). If adjustments are needed, loosen the lock nut and turn the adjustment screw to achieve the correct clearance, then recheck with the feeler gauge and reassemble the valve cover.


What is zero correction in screw gauge?

Zero correction in a screw gauge refers to the adjustment needed to compensate for any slight misalignment between the zero mark on the main scale and the zero mark on the circular scale. This correction ensures accurate measurements are taken by aligning the two zero points when no object is being measured.

How do you adjust valves on a 95 S10 4.3 vortec?

If you look in hood a sticker will tell you the clearance but you get a wrench and a screw driver and a set of feeler gauges. Rotate the motor till.your #1 cylinder is at TDC on compression stroke all.valves will be closed cam.lobes away from the rockers this is when.to.adjust the valves. Losses the nut on the vale back the screw out and stick the feeler gauge in for which ever valve your doing. Then tighten the screw so the gauge can move freely but you have no vertical movement from the rocker arm. Hold the screw and tighten the nut. Recheck to make sure you didn't over tighten the screw while tightening the nut down by sliding the gauge through again. Then move to the next valve. On the f22b1 I believe with #1 at TDC you can also do #4 then turn the motor 180 so 2 is at TDC and adjust 2&3. That should do it.

How do you remove the mounting button from the mirror bracket on the rear view mirror of a 1999 Nissan Sentra?

You get a tool that looks like a flattened tuning fork and slide under the bracket to release the spring, then pull the bracket out. I watched my mechanic try a different method without the above mentioned tool. Use the blade of a very thin feeler gauge. Press the feeler gauge blade between the metal button and the bracket. This also releases the spring. You can then use a screw driver to push out the button.

What is the function of sleeve on micrometer screw gauge?

The sleeve on a micrometer screw gauge is used to provide fine adjustment of the measurement by rotating it to move the spindle in or out slightly. This helps in achieving accurate and precise measurements by allowing the user to make small adjustments without needing to rotate the thimble.


How do you adjust the valve on a 86 Porsche 944?

To adjust the valve on a 1986 Porsche 944, first, ensure the engine is cold and remove the valve cover. Then, using a feeler gauge, measure the gap between the rocker arm and the valve stem for each cylinder. Adjust the gap by turning the adjusting screw on the rocker arm until the feeler gauge fits snugly, maintaining the specified clearance (typically around 0.008 inches for intake and 0.010 inches for exhaust). Finally, recheck the adjustments and reassemble the valve cover.
