I’m new here and hoping for some help please. I have a Ford 335 (1984) which i have bought recently. I seem to have an oil leak from the handbrake housing unit? This is under the tractor on the right hand-side. Someone mentioned to me that it is likely to be a faulty seal in the gearbox driveshaft. If that’s right, which I don’t doubt, then my question is where is that? Do I remove the whole of the unit attached and access it from behind the handbrake discs? Hope someone can help. Many thanks
