🚨 Husqvarna 455 Rancher Chainsaw Guide bar runs dry, gets extremely hot, and smokes
Top Culprit: Clogged automatic oiler delivery channel
Why It Happens: Packed sawdust and chain wood pitch block the exit oil port or destroy the internal nylon worm drive gear.
🛠️ The 60-Second Diagnostic Test
- Remove the guide bar and side clutch cover; run the saw briefly to see if bar oil pumps out from the oil slot.
- Check the oil pickup screen filter inside the oil tank reservoir for blockage or debris.
💡 The Quick Fix Steps
- Clear the bar oil slot channels using a thin scraper tool and blow out the case port with compressed air.
- Replace the nylon oiler pump drive gear assembly if oil flow is missing with clear channels.
