  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on GMC Canyon?

  A:

  You must lift and stabilize your vehicle before starting the Valve Stem Oil Seal and valve spring replacement work. Put the en 46547 into the flywheel teeth after pulling out the service slot plug and lower the vehicle. The next step involves taking out both valve Rocker Arms and Spark Plugs. Place the j-44228-a (J-44228-A) base plate over the service cylinder Spark Plug hole. After that put the j 39313 (J 39313) inside the Spark Plug hole while keeping continuous air pressure from closing the valve. Install the j-44228-a elements carefully over the stud holding the chosen valve while taking care of its powerful spring compression. Twist the swivel nut partially to reach the valve locks and then pry out the valve locks with a magnet. Twist the hand nut to reveal the entire arm then move it aside to take out the valve spring retainer and valve spring. Twist and pull the j 38820 (J 38820) tool to replace the old valve stem seal through its gip points. Before sealing the new stem valve apply clean engine oil to both valve surface and inner seal area then use the j 38820 tool to install the new seal. Reposition the valve spring and valve spring retainer while fixing the arm above them then tighten the swivel nut until the valve locks become visible. Use the j 43059 tool to place valve locks and then free the swivel nut and arm of j-44228-a. Follow this procedure on each cylinder valve to lower air pressure and extract the j 39313 piece from the Spark Plug. Raise the car once more and support it to put in the spark plugs and valve rocker arms on the base plate of the j-44228-a. Finally, install the service slot plug and remove the en 46547 from the flywheel teeth to complete the repair.

  Q: How to Change the Rocker Shaft Spring Kit on a GMC Canyon?

  A:

  The process to replace the Valve Stem Oil Seal and valve spring requires vehicle elevation before removing the service slot plug. Position the en 46547 into the Flywheel teeth before lowering the vehicle. Separate the valve Rocker Arms from the vehicle then remove the Spark Plugs. After applying the j 44228 (J 44228) base plate to the Spark Plug hole position of the serviced cylinder, insert the j 39313 (J 39313) into the Spark Plug hole while maintaining constant air pressure to keep the valve closed. Fasten the j 44228 arm with its swivel nut onto the appropriate valve stud ensuring all valve springs are handled with due caution. Once the swivel nut reaches adequate tightness for valve lock access you can extract the locks with a magnetic tool. Swinging the arm with loose swivel nut removes both the valve spring retainer and the valve spring. The j 38320 (J 38320) tool helps users retrieve and measure the valve spring and remove the old valve stem seal while twisting and pulling. The new valve stem requires a clean application of engine oil both on the valve stem surface and inside of the installation area. After lubrication place a seal protector over the valve stem before using the j 38320 tool to apply the new seal. Set the valve spring retainer and spring aside before swinging the j 44228 arm over the retainer to just tighten the swivel nut enough to insert the valve locks. Use the j 43059 (J 43059) to position valve locks on the valve and then remove the j 44228's swivel nut and arm. Rinse the j 39313 against the Spark Plug hole while relieving the air pressure until all the valves in the cylinder have been serviced to completion. After you remove the base plate of j 44228, set the spark plugs and valve rocker arms correctly before repeating the previous steps to lower the vehicle and install the service slot plug before supporting the vehicle again.
