Video Description

This John Deere 850K dozer came to the shop with a right-side final drive locking up — and what we found inside explains everything. The customer had the final rebuilt 50 hours ago by another shop... and they left out one of the main bearings. That mistake destroyed thousands of dollars in gears and housing. In this video we tear it down, find the damage, and show you exactly what happens when a $14,000 repair gets done wrong. 👉 Subscribe to see Part 2 where we open the other side and see if it’s just as bad. 0:00 A Costly Mistake by Another Shop 1:00 Diagnosing the Locking Track 5:00 Metallic Oil = Bad News 8:30 Metal Found in Final Drive Case 10:40 Pulling the Ripper and Setup 17:30 Building a Custom Lifting Plate 24:30 Cleaning and Prepping the Case 28:30 Finding the Real Damage 35:00 Metal Paste and Bearing Failure 39:00 Discovering What’s Missing 41:00 $14,000 Rebuild Gone Wrong 43:00 Wrapping Up and Parts List 47:00 BONUS: The Bog Hog RC Mud Test For early access to add free videos and members only videos be sure to check out our Patreon page.
