900 L4-1985cc 2.0L DOHC Turbo EFI (1985)
NOTE: Under no circumstances should the chain tensioner extend by more than 11 mm. If it exceeds this measurement, the chain should be
replaced. The tensioner does not need to be replaced (See Figure 3-A). On all 9000 models the torque stay must be removed.
4. Inspect the sprockets and chain guide for wear.
-
The surface between the outer grooves of the chain guide should not indicate any contact marks. If this surface does show signs of wear, the
guides will also have to be replaced (see Figure 3-B). In that instance, the repair will have to be carried out in the usual way (i.e. engine out of
car).
-
If the wear on both the sprockets and guides is acceptable, replace the chain as described below.
