🔧 Product Description

🔌 Function

Opens to admit the air charge into the cylinder and seals against its seat on the compression and firing strokes.

⚠️ Common Signs of Failure

• Hard starting and uneven running with a low compression on one cylinder
• Ticking or tapping from the valve gear that will not adjust out
• Valve clearances closing up between services
• Stem worn or picked up, and the seat face pitted or burnt on strip-down
• Head of the valve tuliped or the margin eaten away

🛠️ Service Notes

• Renew the valve guide and stem seal at the same time — guide 859658 and sealing rings 859659 and 859660 are listed in this run
• Shim 859662 is the clearance-setting item on the same applications; reset clearances after any valve work
