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 dimension (a),
considering the measured value of height ad-
justment (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 measured
value of dimension (a) is lower than the per-
missible value.
