0178-10-10 1824
Inspection / Gauging
Measure clearance of accessible bearings. If wear is
discovered, examine other bearings also. To do this,
remove injection pumps (Job Card 07.04.01).
Replacement of bearing bushes requires cam-
shaft removal (Job Card 04.05.01).
Job:
Remove cover (1) and fit feeler gauge between camshaft and bearing bush.
Nominal clearance: 0,111 - 0,208 mm
Wear limit: 0,3 mm
Once 0,3 mm has been reached, bearing replacement is due.
Reconditioning
We recommend that reconditioning work be entrusted to a Deutz Service Station.
Removing the Bearing Bushes
Remove injection pump with drive (Job Card 07.04.01). Detach cover (1) and remove camshaft (Job Card
04.05.01). Either saw through bearing bushes (2) and/or drive out of the crankcase (3) with a brass pin (Ø 0,94
mm), or withdraw with a puller.
Fitting New Bearing Bushes
Prior to installation, the bearing bushes are to be undercooled (shrunk) in liquid nitrogen down to between -
170°C and -196°C (see Section 3.7). Make sure that all shrink-fit surfaces (bushes and their receiving bores
in the bushes in crankcase) are perfectly clean, i.e. metallically bright.
Be sure to install the bushes in the location shown overleaf, i.e. with the bores in the bushes coinciding with
the bores in the crankcase.
