Reverse Idler Gear End Play

WARNING: This page is about a different variant/trim than selected.

When adjusting reverse idler gear end play, select adjusting shim for reverse idler gear. To select adjusting shim (1), measure clearance between transaxle case (2) and reverse idler gear (rear) (3). Refer to "REVERSE IDLER GEAR ADJUSTING SHIM ".
CAUTION: Only 1 adjusting shim can be selected.
Calculate dimension "Q" (thickness of adjusting shim) using the following procedure to satisfy specification of end play for reverse idler gear.

End play : Refer to "REVERSE IDLER GEAR ADJUSTING SHIM ".

Dimension "Q" = (Q1 - Q2) - End play

Q : Thickness of adjusting shim

Q1 : Distance between transaxle case end face and mounting face of adjusting shim

Q2 : Distance between clutch housing end face and end face of reverse idler gear (rear)

Using a depth micrometer and straightedge, measure dimension "Q1 " between transaxle case end face and mounting face of adjusting shim.

Using a depth micrometer and straightedge as shown in the figure, measure dimension "Q2 " between clutch housing (1) end face and end face of reverse idler gear (rear) (2).
CAUTION: "Q2 " : Measure at 4 point by approximately 90 degrees and use the average value.
Install selected reverse idler gear adjusting shim onto reverse idler gear (rear).
