Note:
- For best results, heat the cylinder head to 150°C before removing or installing guides.
- Some guides may require a pneumatic hammer to remove.
1. Knock out the valve guide from the bottom of the cylinder head.
2. Drive in a new valve guide to the required depth.
Valve guide height after installation:
- Intake: 17.85-18.35mm
- Outlet: 18.65-19.15mm
Deployment
Note: For new guide bushings only.
1. Apply lubricating oil to both the reamer and guide bushing.
2. Turn the reamer clockwise the full length of the valve guide.
3. While removing the reamer from the guide sleeve, continue to turn the reamer clockwise.
4. Wash the guide thoroughly with detergent and water and remove any residue.
5. Check clearance with valve (see above). Make sure the valve moves freely in the guide bush.
Note: Rotate the reamer only clockwise.
