4) Loosen the lock screw for the push rod protecting tube, see plate 50801, item 207, on the roller guide top cover and lift up and remove the protecting tube (2).
5) Dismount the screws (3) which secure the roller guide top cover, take off the cover, the spring (7) and lift out the roller guide (5).
Disconnect any pipes that may be in the way (lub. oil and fuel oil pipes).
6) If the roller guide housing is to be dismantled, the fuel injection pump and the fuel injection pump roller guide are to be dismounted, see working card 514-01.05 and a number af lubricating oil and fuel oil pipes are also to be disconnected.
The roller guide housing (6) cannot be dismantled with the roller guides fitted.
7)If the event of any marks or scores from seizures, these must be polished away.
8)Inspect the spherical stud for deformations (replace as necessary).
Examine the surface of the roller for marks and other deformations.
Make sure that there is free ply between the roller and the bush and the shaft pin, and replace the bush, if necessary.
Replacement of Roller, Bush and Shaft Pin.
9) Remove the lock screw which secures the roller guide shaft pin and push out the shaft pin.
The roller, shaft pin, and bush can now be replaced as required.
10) Blow through the lubricating ducts in roller guide and roller guide housing, and clean the lubricating grooves.
Mounting of Roller Guide.
11)When assembling the parts, which is carried out in the reverse order to the above care must be exercised not to damage the o-rings when mounting the proctecting tube.
12)Adjusting of valve clearance, see working card 508-01.10.

Adjusting of Inlet Valve Clearance.
1)Turn the engine so that the roller, rests on the circular part of the cam, i.e. the inlet valves and the exhaust valves are closed.
2)Loosen the adjustment screws on valve bridge and rocker arm, see fig 1.
Fig. 1.
3)Clearance between valve bridge and valve spindle, see page 500.40.
4)Place the feeler gauge marked with "correct" 0,50 mm above the valve spindle nearest to the rocker arm bracket, see fig 1.
5)Adjust the clearance between valve bridge and valve spindle by means of the adjustment screw on the rocker arm (above the push rod) and tighten the lock nut.
Fig 2.
The feeler gauge is to remain in this position when adjusting the clearance of the other valve.
6)Place another feeler gauge, at the same size 0,50 mm above the other valve spindle, see fig 2.
7)Adjust the clearance between valve bridge and valve spindle by means of the adjusment screw on the valve bridge, and tighten the lock nut, see fig 2.
8)Check that the clearance is correct simultaneously at both valve spindles.

9)Carry out adjustment in the same way as described for the inlet valves, but using the feeler gauge for exhaust valve clearance 0,90 mm.
10)The feeler gauges for checking the clearance have two gauges which are marked "incorrect" and "correct", the latter to be used when adjusting the valve clearance, see fig 3.
After tightening up the counter nuts on rocker arms and valves bridge, be sure that the feeler gauges marked "correct" can be inserted into the two clearances simultaneously as where it must not be possible to insert the gauges marked "incorrect".
