Engine mounting – Checking
condition of resilient mounts
1. Measure height setting (b) with feeler
gauge.
2. Measure dimension (a) with calipers.
3. Calculate permissible value of dimen-
sion (a), considering the measured value of
height adjustment (b):
• Reference values: The permissible value
of dimension (a) is 144 mm when (b) =
5 mm.
• When measured height setting (b) =
6 mm, the permissible value of (a) is
145 mm.
• When measured height setting (b) =
4 mm, the permissible value of (a) is
143 mm.
4. Replace the resilient mount, if the meas-
ured value of dimension (a) is lower than
the permissible value.
