Wastegate Actuator Replacement
4:18
Thread new end link several turns on to the shaft of the
new pre-set actuator assembly.
Hold the actuator assembly with the spine of the spacer
piece upright. Rotate the valve mechanism lever arm to
close the wastegate valve (pushed towards the
compressor end). Fit end link over the lever arm pin.
Attempt to slide the actuator bracket over its retaining
lugs. If the actuator bracket fouls on the lugs or there is
significant clearance between bracket and lugs,
actuator rod length requires adjustment.
To adjust the length of the actuator assembly, remove
from the turbocharger. Rotate the end link to shorten or
lengthen the rod as appropriate. Re-fit, until the
underside of the actuator bracket will just fit over the
mounting lugs with less than 0.5 mm (0.020 in) gap.
The rod length setting is correct if, by rotating end link
clockwise by a half turn, the actuator bracket fouls on
the lugs.
Caution
Contact your local approved agent for the correct
replacement actuator kit (74). It is important to quote
the correct turbocharger assembly number to ensure
supply of the correct pre-set actuator.
Caution
Do not apply force to push the actuator on to its
mounting lugs.
Note
When refitting existing actuator the end link will be
locked in the correct setting.
