PostSubject: Rollerizing Torque Spec & Threadlocker question   Rollerizing Torque Spec & Threadlocker question Icon_minitime1Thu Jun 13, 2019 12:46 pm

I've almost completed the rollerization of my GRiSO and had a couple of questions:

1. Cam Cap Screws (2 per cylinder) - The manual calls these the Camshaft Support Fixing Screws and states they should be torqued to 13 ft. lbs. Pete's directions state 20 ft. lbs. On my bike the factory tightened these to the point where I was worried about rounding off the screw heads. What should I tighten these to?

2. Sprocket Retaining Screw (1 per cylinder)- The manual calls this the Plate Locking Screw and Timing Gear and states to use Loctite 243 on the threads. There was no mention of Loctite in Pete's instructions. Should threadlocker be used here?

Not sure what you mean in 1. as my manual has different names - a picture from parts explosion would help.... But for number 2 the official spec was to use loctite so I did

Sorry. Dunno what you mean by the cam cap screws. Do you mean the ones that hold the breather plate on? They're only 5mm bolts you don't put anything close to 13 ft/lbs on 'em.

Loctite on the sprocket bolt.

I torqued them the same (13 ft/lbs) as the same bolts fixing cam underneath and it's still running !

The two screws in the center of paulbrice's top-most post are my #1.

Thanks for the responses everyone! Next is a test ride, and then I plan to flash the Beetle map.
