Camshaft removal
To pull out the camshaft simply remove bell
1
, gear
2
, fuel feeding
pump
3
, injection pumps
4
and tilt the engine; in this position the
cam followers is not in contact with the camshaft thus making its
removal possible.
How to measure camshaft bearing and journal inside diameter
Dimensions (mm):
A
= 44.000÷44.025
B
= 43.940÷43.960
(A-B)
= 0.040÷0.085 limit value = 0.170
Measure
A
with an inside micrometer gauge and
B
with an outside
micrometer gauge. When repiacing the bearing make the lubrication
hole
1
match with the corresponding crankcase bore.
Dimensions of camshaft journals and housings (mm)
A
= 42.000÷42.025
B
= 41.000÷41.025
C
= 33.200÷33.220
D
= 41.940÷41.960
E
= 40.940÷40.960
F
= 33.140÷33.160
Clearance
(mm)
(A-D)
= 0.040÷0.085 limìt value = 0.170
(B-E)
= 0.040÷0.085 limit value = 0.170
(C-F)
= 0.040÷0.080 limit value = 0.160
Use an outside micrometer gauge to measure camshaft lobe
height.
