8M8211 Shim thickness
.010 in. (0.25 mm)
approximately
1 second
Three 8M8211 Shims will change the
steering time (stop to stop) at high
NOTE
idle by approximately
06 second
The addition of 8B3115 shims will cause a faster right

turn (stop to stop) and a slower left turn. The result is
Three 7M8538 Shims will change the
opposite when shims are removed.
