Sumitomo SH250-6 BREAKDOWN | Leaking Final Drive Repair & 500hr Service

Welome back to Diesel Geesus! 🔧🚜 Today we're heading out to a breakdown on a Sumitomo SH250-6 excavator that's developed a leaking final drive. After diagnosing the problem, we find that the brake seals have failed, allowing hydraulic oil to leak into the final drive gearbox. It's time to get the tools out! We head out to site, remove the complete final drive assembly and bring it back to the workshop for a strip-down, inspection and reseal. Once everything is back together, we head back to the bush, refit the final drive and get the machine back up and running. But we're not finished yet! While we're there, we also carry out a 500-hour service to keep the old Sumitomo earning its keep. Just another day in the life of a heavy diesel field mechanic working on forestry and earthmoving equipment in New Zealand. Grab a coffee, come along for the ride and see how we get on! ☕🔧 If you enjoy heavy diesel repairs, hydraulic diagnostics, excavator maintenance and the everyday challenges of being a field mechanic, consider subscribing to Diesel Geesus.
