Section 06 STEERING AND PROPULSION
Subsection 02 (iBR AND VTS)
smr2009-038-019_a
1. iBR guard
2. Lift up on iBR gate
3. Measurement "B"
5. Subtract measurement "B" from "A" to obtain
the iBR gate backlash (A - B = iBR gate back-
lash).
Example:
– 48 mm - 41 mm = 7 mm
– 1.89 in - 1.61 in = 0.28 in.
iBR GATE BACKLASH
A - B = BACKLASH
MAXIMUM 25 mm (.98 in)
6. Ensure iBR gate backlash is within specified
limits.
If backlash is excessive, inspect and replace iBR
gate parts as required in the following order:
1. iBR locking sleeve (iBR key)
2. Friction sleeves
3. Bushings
4. Contact points (VTS trim ring, "U" arm, iBR
gate)
5. iBR actuator.
NOTE: Look for rotation of the locking sleeve
and "U" arm as you move the iBR gate by hand
which may indicate excess play in the iBR actu-
ator mechanism. Always replace the iBR locking
sleeve first and recheck iBR backlash.
If the backlash is still not within specification af-
ter replacing the iBR locking sleeve, continue dis-
assembly of the iBR gate replacing the previously
listed parts as required.
NOTE: If the contact points on the VTS trim ring
and "U" arm are excessively worn, or the friction
sleeve cams in the "U" arm are worn, replace them
as required.
7. Check iBR gate backlash and gate operation af-
ter parts replacement and reassembly.
FRICTION SLEEVE
REPLACEMENT
The 4 friction sleeves on the VTS trim ring should
be replaced if they show signs of advanced wear
(flat spots), or every 100 hours as per the mainte-
nance schedule.
smr2009-038-021_a
1. Worn friction sleeve (flat spot)
1. To replace the friction sleeves, remove the iBR
gate and VTS ring as an assembly, refer to iBR
GATE AND VTS RING REMOVAL in this subsec-
tion.
smr2009-038-013_a
1. Friction sleeves (2 each side)
2. Remove the worn friction sleeves from the VTS
ring and install new ones.
3. Apply service products, torques, and install
new screws with Scotch Grip threadlocker as
specified in exploded view.
