R (2) If the tachometer drive is damaged:
- replace the DRIVE ASSY-TACHOMETER,WHEEL 1 (2681GM) (Ref. AMM TASK
32-42-68-000-003) and (Ref. AMM TASK 32-42-68-400-003).
R (3) If the tachometer hubcap or the debris guard (if brake fans are
R installed) is damaged:
R - replace the tachometer hubcap or the debris guard (if brake fans
R are installed) (Ref. AMM TASK 32-41-11-000-006).
R (4) If the tachometer drive mechanism is not damaged:
R - do a functional test of the tachometer (Ref. AMM TASK 32-42-00-720-
R 002) or (Ref. AMM TASK 32-42-00-720-003).
R
R (a) if the test is OK:
R - Make sure that the splines of the tachometer are coated with
R grease before final assembly (Ref. AMM TASK 32-41-11-400-006).
R No other maintenance action is necessary.
R (b) if the test confirms the fault:
R - replace the TACHOMETER-WHEEL 1 (19GG) (Ref. AMM TASK 32-42-57-
R 000-001) (Ref. AMM TASK 32-42-57-400-001)
R (5) If the fault continues:
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-933)
related to the ANI-6 analog input signal of the SEC 2 COM and SEC 3
COM (Ref. ASM 27-92/25).
R (6) If the fault continues:
- do a check and repair the wiring from the tachometer (19GG) pins
A/A,C to the first terminal block (Ref. ASM 32-42/02).
R B. Do the functional test given in Para. 4.A.(4)
