Hi I have aquired a Crawley 75 Diesel Tractor which I am now in the midst of restoring, however little information, seems to be available on these machines, I was wondering if anyone had any idea of the thickness of the brake linings when new, mine are nearly down to the rivets, and are at present around 1/8″ thick. when trying them in the drums, it is hard to see that they could be a lot thicker when new, perhaps 3/16″ or 1/4″, does anyone know, or has anyone had any of these shoes relined? I was also wondering if anyone could supply me with a picture of the rear hitch for attaching trailed implements to. I do not have one, so a picture, and perhaps sizes would be gratefully received, so as then I could make one, I have the 3 point lift and pump etc, also I have heard of them been converted to a pulley clutch drive arrangement, rather than the centrifugal clutch and chain drive, I see that there are twin pulleys on the gearbox, does anyone have any details of the belt drive clutch arrangement, as I would like to convert to it as I find the centrifugal clutch a little difficult in tight spaces, any help would be much appreciated. Kind Regards Chris..
