1 8-7. INNER RIM STUD MAINTENANCE (Contd)
When replacing broken rim stud(s), replace studs on both sides of the
Drive studs (1) out of inner rim (2). Discard studs (1).
Disassemble wheel and runflat (para. 8-4).
Drive stud (3) out of inner rim half (4). Discard stud (31.
b. Cleaning and Inspection
Using wire brush, clean studs. Clean all dirt and foreign material from rim with soap and water and
allow to air-dry.
Never use wheel assemblies with studs which are damaged, loose, or
have damaged threads. Damaged studs can cause improper assembly,
which could cause individual fasteners to fail. Any of these situations
may result in serious injury or death.
Inspect inner rim (4) for cracked, broken, rusted, pitted, bent, or loose studs (31, and studs (3) with
damaged, mutilated, or deformed threads.
Perform steps 1 and 2 for stud installation with disassembled wheel.
Perform steps 3 through 11 for stud installation without disassembly of
1. Align splines on stud (3) with splines in inner rim (4) and drive stud (3) into inner rim (4) until stud
shoulder seats against inner rim (4).
Assemble wheel and runflat (para. 8-4).
Align splines on stud (1) with splines in inner rim (2) and drive stud (1) into rim (2) until shoulder of
stud (1) seats against inner rim (2).
Repeat step 3 for all studs (1) being replaced.
Tighten locknuts gradually to avoid bent and broken studs or damage to
wheel components will result.
Install locknuts (6) on studs (11.
After replacing broken stud(s), all rim nuts must be retorqued.
Tighten locknuts (6) to 85 lb-R (115 Nom) in sequence shown.
Tighten locknuts (6) to 125 lb-R (170 N-m) in sequence shown.
Check wheel assembly for gaps at each stud. Use a 0.0015 in. (0.038 mm) thickness gauge to detect
gaps. If gaps are detected, disassemble and reassemble wheel assembly and recheck for gaps. If gaps
are still detected, replace outer rim half (para. 8-4).
Install valve core (7) in valve bore (8).
