🔌 Function

Provides a repeatable manual indication of engine-oil level at the factory measuring point.

⚠️ Common Signs of Failure

• Level markings worn, polished away or no longer legible
• Blade bent or twisted so it fouls the tube and reads high or low
• Oil weeping or misting from around the dipstick where it enters the tube
• Dipstick not seating fully, or lifting out of the tube in service
• Readings inconsistent between checks taken on level ground

🛠️ Service Notes

• Renew O-ring 949187 when the dipstick is fitted, as an oil leak at the tube is normally the seal rather than the stick
• Supersedes 3807083, so an order placed against the old number is filled with this dipstick
• Confirm the reading against a known oil quantity after fitting, since the blade length and stop position set the calibration
