Main Seal. Fit the pivot pin into the square section at the rear of the prepared bottom case
ensuring that the pin hangs out of the case with the notch on the pivot facing towards the operating
rod of the tillerpilot. Fold the metal pin into its recess in the lower case. Position the Case Seal
E02498 onto the case bottom ensuring it is pushed fully into the grooved housing. Carefully lift the
case seal from around the area of the pivot pin and using a cotton bud apply Dow Corning 1205
Primer 260029 to the case. Fill a small hypodermic syringe with Dow Corning 3140 Silicone
sealant 260001 and run a small bead of sealant completely around the case seal in the area of the
square as shown below.
Refit the seal onto the case.
Final Assembly. Carefully position the case top onto the bottom ensuring that the case seal is
correctly located all round, squeeze the top and bottom halves of the case together, and fit the 10
screws 200088. Tighten down evenly all round in the sequence shown below:
Post Assembly Test. Remove the Tiller Connector E02607 and push the Tillerpilot Test Syringe
Part No. TP-SRY over the end of the Push Rod E02522. Depress the syringe piston and release,
the piston should return to its original position indicating that the integrity of the case seal has not
been compromised during fitting. Remove the Test Syringe and refit the Tiller Connector.
