Valves And Valve Stem Seals; Removal From The Cylinder Head; Installation - Triumph Rocket III Classic Service Manual

Cylinder Head
10. In the sequence shown above, tighten bolts 1
through 8 through a further 90° using tool 3880105-
T0301 or similar to measure the torque-angle.
11. Tighten bolts 9 and 10 to
10
Nm.
12. Refit the bolt head cover to the right hand rear
cylinder head bolt.
13. Lubricate the tappet buckets with a
50150
solution of
molybdenum disulphide grease and engine oil, then
refit them and the valve shims to their original
locations in the head.
14. Refit the camshafts (see page 3-17>.
15. Refit the sound suppression bolt to the camshaft
drive chain chest and tighten to
10
Nm.
16. Check and adjust the valve clearances (see page 3-
19).
lZ Reconnect the coolant temperature sensor and the
oil pressure sensor.
18. Refit the bypass and top hoses.
19. Refit the oil tank (see page 9-17>.
20. Refit the throttle bodies (see page
11-190>.
21. Refit the exhaust system (see page
11-203
for
Rocket III and Classic, see page
11-207
for Rocket III
Touring).
22. Refit the radiator (see page
12-/4).
23. Refit the fuel tank (see page
11-150
for Rocket III
and Classic, see page
11-154
for Rocket III Touring.
24. Refit both engine in-fill panels, tightening the fixings
t04Nm.
25. Start the engine and allow it to idle while checking
for air, oil, coolant and exhaust leaks. Rectify as
necessary.
26. Check and top up the cooling system (see page
12-
5).
2Z Check and top up the oil level (see page 9-7>.
Valves and Valve Stem Seals
Removal from the cylinder head
1. Remove each valve from the head using a valve
spring compressor. The compressor must act on the
top cup to allow removal of the valve collets.
2. Once the collets are released, remove the following
items:
• collets
• valve spring cap
• valve spring
• valve stem seal
• valve spring thrust washer
Installation
1. Apply a thin coat of molybdenum disulphide grease
to the valve stem.
2. Install the valve into the valve guide and refit the
thrust washer to the valve spring recess (if removed).
3. Fit the valve stem seal over the valve stem and, using
a suitable tool, press down fully until the seal is
correctly seated over the valve guide.
Note:
• During fitment of the valve stem seal, two
distinctly different degrees of resistance will be
noted when the seal is correctly fitted.
4. Firstly, press the seal down the valve stem until the
lower side of the seal comes into contact with the
valve guide. Greater resistance is felt at this contact
point and further gentle pressure is then required to
locate the seal over the top end of the valve guide.
5. On application of this pressure, the seal can be felt to
positively locate over the top face of the valve guide.
Once correctly positioned, the seal cannot be
pushed down any further.
Incorrect fitment of the valve stem oil seals could lead to
high oil consumption and blue smoke emissions from
the exhaust system. Do not use excessive force in fitting
the seal as this may break the seal ring.
6. Install the valve spring and spring cap.
Z Compress the valve spring ensuring that the spring
is compressed squarely to prevent damage to
components.
