Hello guys,
I think I've either done something drastically wrong in the rebuild or missed something or....?
I rebuilt it back end of last year (then my back again decided it wouldn't play anymore) fast forward to last weekend when I was well enough to put it back into its rightful place.
So Disco is on 4 ramps, transfer box re-installed, whilst everything was apart and accessible, the autobox was also treated to a new filter and new fluid. New fluid put into the transfer box (2.5L) and all linkages reattached for the high/low ratio & diff lock. Things going swimmingly I think.
Now before I put the props back on I thought I'd start it up & let it go through the gears to allow the autobox to circulate the fluid around, so start up, engage D,3,2,1 & back & forth, everything was fine so I thought lets engage the transfer box and see if it works. High / low were selected, no weird noises to report, diff lock in high / low all worked with no untoward noises. By this point I was starting to feel happy at a job well done, both boxes were working as they should and....and NO LEAKS
Engine switched off, I get underneath and start to contemplate putting the propshafts back on, now for some reason, I don't know why I just put my hand on the rear output flange and it was hot, bloody hot. Not hot enough to burn, but hot enough that you couldn't keep your hand on it??? I then thought 'Oh dear, what have I done' put my hand on the front output flange to compare and that was fine, not hot at all???
The only thing I think it could be is the bearing on the rear output getting overly hot for some reason??? The bearing was new and was pre-greased & I doused everything with gear oil before putting the box back in.
Could I have -
A) Over tightened it to the shaft?
B) Got a duff bearing?
C) Help I'm running out of ideas
TIA
