Though I would start a thread of my non 80” specific machinations
Today I 'arve mostly been dismantling a winch!
Many years ago, possibly even the last ever Langley Farm, my brother and I ended up trashing his Discovery.
At the beginning of the weekend I arrived in Yorkshire as usual to help run the event with the rest of my YLRoC cohorts. I recall helping my brother replace the control relays with a nice new single relay recently acquired from Warn. Tested it and all was OK.
The rest of the weekend we would take groups of people round the off road, mainly our helpers such as the Scouts, Air Cadets and St. Johns chaps, especially the infamous mud hole. For this I of course used my brothers Disco instead of mine :evilgrin:
I ended up with mud coming out of all the heater vents, even around the transmission tunnel. At the time this resulted in having to replace the alternator and the heater matrix as once the mud dried solid !!
Anyway, many years later (well last year) djdommyp bought HVH’s remains from my brother, the breaking of which is in another thread.
Well needless to say, the winch never worked after the mud hole either.
So today I decided to finally try and open up the sized winch to see if it is worth refurbishing.
I finally managed to separate the gearbox from the drum and motor assembly after a long war with the cap screws that held the two halves together.
The Gearbox came apart quit easily but mud and gunge had made its way in (fortunately it was never run after its dunking so the mud wasn’t used as grinding compound)
The freewheeling mechanism was also seized up, as you can see the little cam switch would not turn.
Next job was to split open the gearbox, this was achieved by removing 10 hex headed bolts then breaking the seal between the two halves with the judicious tap of a screwdriver an soft headed hammer
A bucket of Gunk and a brush and I had all the components cleaned. The only pig was getting the freewheel sleeve first to move then to remove it as it appeared rusted in place.
However a bit of 3”x2” whacked in as a mandrel first broke the corrosion then with the aid of WD40 I got it to spin before removing and thorough cleaning.
Once reassembled (dry, still needs grease etc.) the gearbox now runs freely.
Onto the motor, again the appeared seized, but I managed to get it to spin. Promising, so I progressed by removing the motor case bolts and removed the end piece to reveal the dried mud level !!
With the armature out, I could start to clean all the mud out. Once I removed the brush assembly I could see that the brushes were seized and the springs rusted through.
Oh well. I shall now find out whether I can get a replacement unit or springs tomorrow.
That said when the cleaned winch was reassembled it now seems to run smoothly in freewheel so there is some promise.
Watch this space.
