Overview
A diagnostic and disassembly walkthrough focused specifically on identifying a power steering orbital seal leak on a 1976 Massey Ferguson 275 with a Perkins diesel. The instructor confirms the column is dry-type, rules out the column seal as the culprit, and shows how to access and remove the orbital using an 11/16 crowfoot on a long extension. Ends before the actual seal replacement, so expect a follow-up video for the repair itself. Best for MF 275 owners troubleshooting the same leak.
