Riveting aluminium parts
1.0 Recommended tools and equipment
-
Stud welding apparatus (refer to Service Information 5 03 03 975) with gas bottle containing inert gas
(82 % argon, 18 % CO
2
).
-
Stainless steel stud (sourcing reference via BMW Parts Service picture board 83-0286 Aluminium and
steel/bonding and welding)
-
Universal riveting tool (refer to Service Information 5 03 03 975)
-
Hand riveting tool for blind rivet nuts and blind rivet bolts (refer to Service Information 5 01 00 532 or Workshop
Equipment Planning CD, Chapter 7).
2.1 Extracting punch rivets:
-
Grind off paint and dark grey coating of punch rivets.
-
Position bolt centrally on the rivet and weld on vertically. The area in which the bolts are welded on should be
between the two grounding terminals. Position both terminals, if possible, on the top side of the metal plate on
which the rivet is located.
-
Extract bolt with welded-on rivet using universal riveting tool. Use a large plastic nose piece if not otherwise
specified in the repair instructions. Check plastic nose piece prior to use for wear.
-
Plastic nose piece must rest on sheet metal all round; if necessary, grind off plastic noise piece in collision area.
Do not push riveting tool forcefully onto special-steel bolts.
Do not use riveting tool to bend special-steel bolts.
-
Pay particular attention to central positioning of the bolt when using the small plastic mouthpiece.
-
Follow the equipment manufacturer's instructions for use.
2.2 Drilling out punch rivets:
Only if extraction proves repeatedly unsuccessful or the rivet cannot be accessed with the universal riveting tool.
-
Drill out rivets with a 6 mm dia. carbide drill bit.
-
Punch rivets can be drilled out on both sides. When drilling from the protruding rear side, spot-drill the rivet shank
only and remove the rest with a rivet punch.
-
Use a drift punch to remove all punch rivet remnants in the aluminium (risk of corrosion).
-
Clean vehicle to remove all traces of chips (risk of corrosion).
2.3 Drilling out blind rivets:
Only when a part is repeatedly replaced.
-
Drill out rivet head only with 6 mm dia. metal drill bit. Knock out rivet remnants with a drift. Use existing 6.7 mm
hole for blind rivet.
-
Clean vehicle to remove all traces of chips and rivet remnants (risk of corrosion).
