Installation
- Check the part number(s) for your application against the part number(s) listed on the instruction sheet to confirm you have the correct kit.
- Do not use any washers with these ARP flywheel bolts — they are designed to be installed without them.
- Make sure there is an adequate chamfer around the bolt holes on the flywheel to clear the radius under the head of the bolt.
- Lubricate the threads of each bolt with Loctite 242 and the underside of the bolt head with ARP Ultra-Torque Fastener Assembly Lubricant. Then install the flywheel onto the crankshaft and tighten the bolts hand tight.
- Using an alternating (criss-cross) pattern, torque the bolts to 150 ft-lbs using the specified lubricants from Step 4.
NOTE: Always tighten flywheel bolts in an alternating, criss-cross sequence to seat the flywheel evenly against the crankshaft flange.
