Alternator Belt Inspection and Adjustment
NOTE: When using a new belt, first adjust the deflectionor tension to the values for the new belt, then readjustthe deflection or tension to the values for the used beltafter running engine for five minutes.
Deflection methodi
Apply a force of 98 N (10 kgt,22lbll, and measure thedeflection between the alternator and crankshaft pulley.
Detlection:
Used Belt:8.5 - 11.5 mm (0.33 - 0.45 inlNew Beft: 5.5 - 8.0 mm 10.22 - 0.31 inl
NOTEr lf the belt is worn or damaged, replace it.

Belt tension gauge m6thod:
Attach the belt tension gauge to the belt and measure thetension. Follow the gauge manufacturer's instructions.
Tension:
Used Belt:340 - /€0 N (35 - 50 kgf, 77 - 1r0 tbf)New Belt: 690 - 880 N (70 - 90 kgf, 150 - 200 tbt)
NOTE: lfthe belt is worn or damaged, replace it.

Description
Hydraulic Flow (cont'dl
2nd Gsar
As the speed of the vehicle reaches the prescribed value. shift control solenoid valve A is turned ON by the pCM.Modulator pressure (6A) in the left end of the 1-2 shift valve is released by turning shift control solenoid valve A ON.The 1-2 shift valve is moved to the left side and uncovers the port to allow line pressure (5) to the 2-3 shift vatve. Linepressure (5) changes to 2nd clutch pressure (20) at the 2-3 shift valve, The 2nd clutch pressure {20) is appli€d to the2nd clutch. and the 2nd clutch is engaged.
Fluid flows by way of:- Line Pressure (4) + CPB Valve - Line Pressure (5) * 1-2 Shift Valve - Line pressure (S) * 2-3 Shift Valve- 2nd Clutch Pressure (20) - 2nd Clutch
The hydraulic pressure also flows to the lst clutch. However, no power is transmitted because of the one-wav ctutch.
NOTE:
. When used, "|eft" or "right" indicates direction on the hydraulic circurr_' The hydraulic circuit shows the'97 - 98 models (7 positions); the '99 - 00 models (6 positions) is similar,
