Tractor time

There has not been much time spent on my cars recently due to work on the Lightweight (more on which another time) and work on my tractor. I've owned this for the past five years or so and has come in really handy when moving engines around or fetching wood for the farm, but the hydraulics, which provide power to lift the front loader or rear implement, have over the years grown weak.
A gear driven pump provides the hydraulic power, but this is hidden away in the back of the tractor behind the gearbox and below the axle. The combined gearbox and rear axle oil was drained and while this was happening, I set about removing any parts which would get in the way.





With all the parts out of the way the rear case came off without any problems, using the two jack-off bolts to separate it and the Massey 35 to hold the weight.






It doesn't look too bad in the rear housing, though there is a bit of silt in the bottom of the case, not too surprising to me for a farm tractor of this age. I shall clean all this out as best I can, then put new oil back in, all 12 gallons of it.

I moved the rear case, with the hydraulic pump, into the workshop to make it easier to work on. Unfortunately there are no obvious signs of failure yet, so I guess a hydraulic pump rebuild could be on the cards.
