Subaru Legacy BN/BS (2015-2019) Service Manual: Installation
1. CAM CARRIER RH 1. Insert the steel rods into ST, and set the engine so that the camshaft RH is facing up. CAUTION: • If the engine is standing on one side without inserting the steel rod into ST, engine may lose balance and fall down. Be sure to insert the steel rod into ST to extend the length. • Use the steel rod with enough strength. • Be careful not to pinch the engine harness with ST.
2. Apply engine oil to the valve shim and the roller rocker arm pivot, and install the valve shim and the roller rocker arm pivot to the cylinder head RH.
3. Apply engine oil to the O-ring and the roller rocker arm, and install the O-ring and the roller rocker arm to the cylinder head RH. NOTE: Use new O-rings.
4. Apply liquid gasket to the mating surface of cam carrier RH as shown in the figure. NOTE: • Before applying liquid gasket, degrease the old liquid gasket seal surface of the cylinder head RH and cam carrier RH. • Install within 5 min. after applying liquid gasket. Liquid gasket: THREE BOND 1217G (Part No. K0877Y0100), THREE BOND 1217H or equivalent Liquid gasket applying diameter: 3.0±0.5 mm (0.1181±0.0197 in)
5. Install the cam carrier RH to the cylinder head RH. (1) Mount the cam carrier RH, then tighten all bolts with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure. NOTE: Set the intake camshaft RH and the exhaust camshaft RH to the zero-lift position.
(2) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.
(3) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.
(4) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.
(5) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure.
(6) Loosen the bolts (3 places) by 180° in numerical order as shown in the figure.
(7) Tighten the bolts (3 places) with a torque of 18 N·m (1.8 kgf-m, 13.3 ft-lb) in numerical order as shown in the figure. NOTE: After tightening, if the liquid gasket is squeezed out onto the seal surface of the chain cover, completely remove any squeezed-out liquid gasket.
6. Set the part so that the intake manifold is on the upper side. 7. Install the cam sprocket RH. Cam Sprocket > INSTALLATION NOTE: This procedure is required only when the cam carrier RH is removed for disassembly. 8. Check the cam clearance. Cam Clearance > INSPECTION 9.

Insert the steel rods into ST, and set the engine so that the camshaft LH is facing up. CAUTION: • If the engine is standing on one side without inserting the steel rod into ST, engine may lose balance and fall down. Be sure to insert the steel rod into ST to extend the length. • Use the steel rod with enough strength. • Be careful not to pinch the engine harness with ST.

Disassembly
NOTE:When replacing the coupling sleeve and synchronizer hub, replace them as a set. Because these must engage at the specified point, avoid disassembly as much as possible. If it is necessary to disassemble, mark the engaging points on the splines beforehand.1. Put vinyl tape around the main shaft ...
