Honda HR-V: CVT Differential Backlash Inspection (CVT)

Inspection

1. Differential Backlash - Inspect

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Install both axles into the differential, then place the axles on V-blocks (A)
  2. Check the backlash of the pinion gears (B) using a dial indicator (C).

Standard: 0.05-0.15 mm (0.0020-0.0059 in)

  1. If the backlash is out of the standard, replace the differential carrier.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

Inspection

NOTE:

  • If the transmission housing, the torque converter housing, the differential carrier, the carrier bearing/bearing outer race, or the thrust shim is replaced, the bearing preload must be adjusted.
  • Apply a light coat of clean transmission fluid on all parts before installation.

1. Carrier Bearing Preload - Inspect

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Remove the carrier bearing outer race (A), the 68 mm thrust shim (B), and the oil guide plate (C) by heating the torque converter housing to about 212 ºF (100 ºC) using a heat gun (D).

    NOTE:

    • Do not heat the torque converter housing more than 212 ºF (100 ºC).
    • Let the torque converter housing cool to room temperature before adjusting the bearing preload.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Install the carrier bearing outer race (A), the 68 mm thrust shim (B), and the oil guide plate (C).

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Drive the carrier bearing outer race (A) until it bottoms using the 15 x 135L driver handle and the 62 x 68 mm bearing driver attachment.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Install the differential assembly (A).

Continuously Variable Transmission (CVT) - Testing & Troubleshooting
Fig. 2: Torque Converter Housing With Torque Specifications (AWD)

  1. Install the torque converter housing (A) with the dowel pins (B), and tighten the bolts in a crisscross pattern in at least two steps.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Install the preload inspection tool
  2. Press the preload inspection tool gradually by tightening the bolt (A) and fix it.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. Rotate the differential assembly in both directions to seat the bearings.
  2. Measure the starting torque of the differential assembly using the preload inspection tool, a torque wrench (A), and a socket (B).

NOTE: Measure the starting torque at normal room temperature in both directions.

Standard:

New Bearing: 1.25-1.65 N.m (12.7-16.8 kgf.cm, 11.0-14.6 lbf.in)
Reused Bearing: 0.95-1.35 N.m (9.7-13.8 kgf.cm, 8.4-11.9 lbf.in)

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

  1. If the measurement is out of the standard, remove the 68 mm thrust shim, and measure its thickness, then select a suitable 68 mm thrust shim.

NOTE:

  • To increase the starting torque, increase thickness of the 68 mm thrust shim.
  • To decrease the starting torque, decrease the thickness of the 68 mm thrust shim.
  • Do not use more than two thrust shims to adjust the starting torque.
