Where are the VVT sprockets located on the engine?
Located on the camshaft, VVT sprockets (also known as cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency. To ensure proper performance for this
What are the tools in the timing chain?
Tool B is the camshaft locking plate, which holds the camshafts aligned in the correct position relative to the crank at TDC. Tool C is the intake sprocket holding tool. This is used to hold the intake sprocket in place in addition to maintaining the correct tension on the timing chain. Tool A is the exciter ring positioning tool.
How do you push in a new camshaft?
Push the cam in and use the cam bolt in the new camshaft to give you leverage. You need to push in, turn, and move the head of the cam around to get the lobes to move over the cam bearings. Be gentle. Have I said that enough yet?
How to install a 4 cylinder cam gear?
1. Remove both front camshaft bearing caps. 2. Assemble No. 536176 camshaft gear holder to the back side of the camshaft gears. 3. Assemble No. 536174 camshaft gear holder to the cam gears and No. 536176 with four (4) bolts. Torque the bolts to 19 ft. lbs. (25 N•m). 4. Install and tighten two (2) bolts that attach the No. 536174 camshaft gear
What should torque be on a cam sprocket?
Torque the cam sprocket bolts to 94 to 115 ft-lb. Check that your original chain marks still align with the marks on the sprockets and the lobes still point away from the center of the engine. Remove the tensioner locking wire you in- stalled. Inspect your work carefully.
How do you install a camshaft on a Nissan QR25DE?
Attach the sprockets to the new cams and screw the bolts in by hand. If you have positioned the cams correctly, only a slight rotation of the cams will be needed to engage the dowels and sprockets. Check to see that the sprockets are fully seated against the cams before torquing the bolt tight.
When to remove the VVT actuator from a camashaft?
DON’T FORCE ANYTHING and remember that as soon as the Timing Chain is finally on the sprockets and the New Bolts (cannot re-use the old sprocket bolts) have been “Torqued to Yield” with the Torque Angle Meter… then the above tool should be removed before you forget it is attached at the back of the camashafts “Chance Favors The Prepared Mind…”
