Check any deviation in engine bed parallelity.
Measure distances B and B2. The difference must
not exceed 3 mm (0.2") for each rubber pad.
The difference between rubber pads must not ex-
ceed .5 mm (0.06") for dimensions C and C2.
Angular misalignment between the bed plane and
the engine brackets is adjusted by correcting the bed
plane beneath the foot of the rubber pad.

Installing the engine on the
engine bed with mounts of type 1
Before adjustments can be made, the engine must
rest on the rubber mounts for at least twelve hours
but prefferrably more than two days.
Never use rubber mounts other than those intended
for each particular engine type.
This chapter explains the procedure using a mount
which is adjustable in the vertical plane with a nut.
Mounts adjusted with shims follow in principle the
same procedure, but use shims to adjust the engine
height.
A = Nominal height
D2: 30 mm ±8 mm (5.±0.27")
All other engines: 7 mm ±8 mm (4.6±0.3")
V = Lateral adjustment ±8 mm (0.30 ")
B = To verify height adjustment, 0-6 mm (0–0.62")
Height adjustment is carried out using the adjust-
ment nut ().
NOTE! Verify that the mount is not adjusted too high.
The distance (B) between the big washer and the ad-
justment nut () must not exceed 20 mm (0.8").
Lateral adjustment is carried out using the slip-
shaped holes in the base of the rubber mounts.
These can be turned facing forward or backwards,
whichever allows the best accessibility. The basic
position of the rubber mounts is at the intermediate
position with the base plate holes in the bed’s longitu-
dinal line.
