10 Fit the Torque Converter Housing - Gearboxes with
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 A (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 10d to the housing 10a.
b Carefully locate the torque converter casing on the front
case. Fit new 10.9 grade bolts (shown at B) as follows:
M10 x 35 mm bolts (21 off). Note that on some
gearboxes spacers are fitted under bolts at positions Y.
M8 x 25 mm bolt at position 22.
M8 x 45 mm bolt at position 23.
Progressively torque tighten the bolts in the sequence
shown.
