23 bolt fix only
Important Note:
Only the specified sealant can be used. The
machine
MUST NOT
be operated for at least 6 hours after
sealant has been applied and the converter housing
assembled. This is to allow time for the sealant to cure.
a
Make sure that the front case and torque converter
housing (
10a
) mating faces are clean, dry and
undamaged. Apply a 3 mm wide bead of Loctite 509
sealant to the front casing as shown at

(pump not
shown for clarity). Make sure that sealant is applied
between all the port channels as shown. Take extra
special care at positions
X
as sealing is critical in these
areas. Be sure not to block galleries with sealant. Fit a
new ‘O’ ring

to the housing
10a
.

case. Fit new 10.9 grade bolts (shown at

M10 x 35 mm bolts (21 off). Note that on some
gearboxes spacers are fitted under bolts at positions
Y
