Question 1

How to service and repair the Rocker Shaft Spring Kit on the right side on Cadillac DeVille?

Accepted Answer

For right valve spring maintenance get j 38820 valve stem seal tool, j 39313 Spark Plug port adapter, j 43059 valve retainer tool, j 44211 on-vehicle valve spring compressor, and j 44214 flywheel holder. Raise the vehicle and take out the right camshafts to begin work. Beginning with the removal of both parts connecting the transaxle case and engine Oil Pan then proceeding to take off the torque converter cover. Place the j 44214 tool and let the vehicle descend to the lowest position. Before sparking plug removal clean the recess area to stop foreign material entry. Install the base plate of j 44211 over the Spark Plug opening before removing the Spark Plug from the service cylinder. Set the j 39313 valve into the Spark Plug hole and use steady breath pressure to block the valve opening. Install the arm and swivel nut of the j 44211 assembly onto its valve stud and tighten the swivel nut enough to reach the valve locks. Use a magnet to take off the valve locks from their position then loosen the swivel nut and swing the arm backward to unfasten the valve spring retainer and spring. To extract the old valve stem seal you can use the j 38820 tool set if needed. Put clean engine oil on the valve stem and inside the new seal before pressing in the seal using j 38820 . Insert the valve spring and spring retainer into their respective spaces. Move the j 44211 arm over both parts and apply just enough torque to the swivel nut for fitting the valve locks. Position the valve locks onto both sides of the j 43059 before dismounting the swivel nut and arm from the j 44211. Service each valve using the same approach by releasing air pressure then taking out the j 39313 tool from the Spark Plug hole. Put the Spark Plug in its position after you remove the base plate of the j 44211 . Put this method through the rest of the cylinders before putting back the right Camshaft set. Rise the vehicle up and replace the j 44214 piece before securing the torque converter cover in place. Let the vehicle down before securing the Oil Pan to its transaxle brace by tightening bolt threads to 50 nm (37 ft. Lbs.).

Question 2

How to replace the Rocker Shaft Spring Kit and Valve Stem Oil Seal on the left side on Cadillac SRX?

Accepted Answer

You have to uninstall the Starter first to reach the left side valve components. Mistakes often occur because the en 46106 (Flywheel Holding Tool) is not used. The Crankshaft may move which forces complete disassembly of the Camshaft timing machinery. Put the en 46106 in position to stop Crankshaft movement before taking off camshafts and rocker arms. Plug the appropriate cylinder and fasten the j 39313 Spark Plug port adapter to access compressed air. Place the en 46110 (On-Vehicle Valve Spring Compressor) onto the cylinder top. When using the en 46110 setup handle valve springs carefully because they are hazardous to dismantle if pressed within 24.0 mm (0.943 in). Tighten the valve spring compressor nut with en 46110 and install the en 46117 tool to remove valve keepers. Unfasten the en 46110 valve spring compressor nut and take out the valve spring retainer combined with valve spring. To remove the valve stem seal utilize tool en 46116. You need to use tool en 46116 to put in a new valve stem seal then add both valve spring and retainer. Cease holding the valve spring nut with en 46110 before installing new valve keepers at the proper angle on their tapered ends. After loading the spring hold the valve keepers inside. Later detach the en 46110 system and disconnect the j 39313 air supply. Place the spark plugs then rocker arms and camshafts on the engine while taking out the en 46106.

Question 3

How to service and repair the Rocker Shaft Spring Kit and Valve Stem Oil Seal on the right side on Cadillac XLR?

Accepted Answer

To access the right valve stem oil seal and valve spring for service work start by uninstalling the right camshafts and removing the Starter motor. Attach the en 46326 flywheel holder while preparing the Spark Plug area by cleaning the recess. Insert the j 39313 into the Spark Plug hole while keeping the valve closed by maintaining constant air pressure. Place the base plate of j 44211 into position over the Spark Plug hole. Put the j 44211 arm and swivel nut above the valve stud of the vehicle body before you tighten the swivel nut just enough to grab the valve locks. Specialize a magnet to take the valve stem locks off next loosen the swivel nut to pivot the arm away from the valve and disassemble the spring retainer and valve spring. Keep removing the valve stem seal for replacements only; use the j 38820 to hold and turn the old seal out. Load clean engine oil into the new valve stem seal before fitting it with a j 38820 tool. Lock the valve springs into place with the help of a magnet after setting the valve spring retainer and valve spring back in position while keeping the j 44211 swivel nut tightened. Lift air pressure from j 44211 head assembly and take off its swivel nut and arm before dismounting j 39313 and j 44211 base plate. Completing the process means installing the new Spark Plug first then repeating these steps for all other cylinders before reattaching right camshafts and taking out the en 46326 flywheel holder to place the Starter motor.
