FRONT TIMING CHAIN CASE








Removal and Installation

NOTE:
^ This describes procedures for removal/installation procedure of the front timing chain case and timing chain related parts without removing the oil pan (upper) from the vehicle.
^ When oil pan (upper) needs to be removed or installed, or when rear timing chain case is removed or installed, remove oil pans (upper and lower) first. Then remove front timing chain case, timing chain related parts, and rear timing chain case in this order, and install in reverse order of removal.

NOTE: Necessary only when removing secondary timing chains.





25. Remove the IVT control solenoid valves.
^ Discard the gaskets and use new gaskets for installation.





26. Obtain compression TDC of No. 1 cylinder as follows:
a. Rotate crankshaft pulley clockwise to align timing mark (grooved line without color) with timing indicator.





b. Check that intake and exhaust camshaft lobes on No. 1 cylinder (right bank of engine) are located as shown.
^ If not, turn the crankshaft one revolution (360°) and align as shown.








27. Lock the drive plate (A/T), flywheel (M/T) attached to the starter bolt hole using Tool.
Tool number : KV10117700 (J-44716)

CAUTION: Do not damage the ring gear teeth, or the signal plate teeth behind the ring gear, when setting the Tool.





28. Remove the crankshaft pulley as follows:

Tool number : KV10109300





b. Position a pulley puller at recess hole of crankshaft pulley to remove crankshaft pulley.

CAUTION: Do not use a puller claw on crankshaft pulley periphery.





29. Remove the front timing chain case.
a. Loosen the front timing chain case bolts in the order as shown.





b. Insert the appropriate size tool into the notch (1) at the top of the front timing chain case as shown.
c. Pry off the case by moving the suitable tool (2) as shown.
^ Cut liquid gasket for removal using Tool.

CAUTION:
^ Do not use a screwdriver or similar tool.

CAUTION: Do not damage the front cover.





32. Use a scraper to remove all of the old Silicone RTV Sealant from the front timing chain case and opposite mating surfaces.

CAUTION: Do not damage the mating surfaces.

INSTALLATION





1. Install dowel pins (right and left) into front timing chain case up to a point close to taper in order to shorten protrusion length.





2. Install the new front oil seal on the front timing chain case. Apply new engine oil to the oil seal edges.

NOTE: Install it so that each seal lip is oriented as shown.





a. Install the new front oil seal so that it becomes flush with the face with front timing chain case using suitable drift.

CAUTION: Press fit straight and avoid causing burrs or tilting the oil seal.

NOTE: Make sure the garter spring is in position and seal lip is not inverted.





3. Apply Silicone RTV Sealant to front timing chain case as shown.
^ Use Genuine Silicone RTV Sealant, or equivalent. Refer to "RECOMMENDED FLUIDS AND LUBRICANTS".
^ Before installation, wipe off the protruding sealant.
4. Install dowel pin on the rear timing chain case into dowel pin hole in front timing chain case.
5. Loosely install the front timing chain case bolts.
Bolt position - Bolt diameter
1, 2 : 8 mm (0.31 inch)
3 - 22 : 6 mm (0.24 inch)





6. Tighten the front timing chain case bolts in the order as shown.
^ Retighten the front timing chain case bolts in the order as shown.
