the main shaft and the fitted carriage is fully back.
4. Select the other carriage sub-assembly and fit over the bearing support rods,
pushing the bars into the other support rod hole. When both carriages and
bars are in position tighten the M8 x 30 Grub screws (15) to 22Nm
5. Selecting one carriage at a time, slide the carriage assembly back to the side
plate, pushing via the cam follower bearing (
this will align the carriage parts
).
Finally tighten the cap heads M8 x 25 (72) cap head to 22Nm.
6. Check that the carriages are free to move with little or no ‘stiction’.

14. With a grease gun filled with 502375 grease, pump grease into the nipple and
hose (approx. 14 strokes of the grease gun), until grease comes out of the
hose. Clean off excess grease and connect the hose ends to the opposite cam
follower pin ‘push in’ fittings.
