Replacing Rivets With Bolts
REPLACING RIVETS WITH BOLTSCAUTION: Drill only where a rivet was removed. Drilling outside the rivet hole will weaken the frame.
1. Line drill a hole the size of the bolt through the old rivet hole. Example: for a 11.11 mm (7/16 in) diameter rivet, use a 12.7 mm (1/2 in) drill bit.
2. Position the support.
3. Replace the rivets that were removed with the next larger size bolts. Insert the bolts, nuts and washer that are Property Class 9.8 metric (Grade 8) in the drilled holes.
