– Fit assembly cone -T10133/5- with new combustion chamber
ring seal -1- from repair kit onto injector -2-.
– Using assembly sleeve -T10133/6- , push combustion cham‐
ber ring seal onto assembly cone -T10133/5- as far as it will
go.
– Turn round assembly sleeve -T10133/6- and slide combustion
chamber ring seal into groove.
Note
The combustion chamber ring seal is widened when it is pushed
onto the injector. After pushing it on, it therefore has to be com‐
pressed again. This is done in two stages, as described below.
– Push calibration sleeve -T10133/7- onto injector as far as it will
go and simultaneously turn it slightly (approx. 180°).
– Pull calibration sleeve -T10133/7- off again by turning it in the
opposite direction.
– Push calibration sleeve -T10133/8- onto injector as far as it will
go and simultaneously turn it slightly (approx. 180°).
– Pull calibration sleeve -T10133/8- off again by turning it in the
opposite direction.
