I remembered this thread and now have the same problem with my 1956 D7 17a. I bought it in 2000 and it has done great work, digging out a small lake, grubbing stumps on the farm and levelling the chalk roads with the blade set at an angle.
I was just finishing some work pushing a load of saplings into a heap ready to burn, which was easy first gear work, when I noticed a small amount of white smoke coming out of the gearbox filler, no unusual noise and I assumed this was a sign that the transmission brake needed adjusting so followed the instructions in the manual, but like LG 78 said I saw that the linkage was worn and needed welding. It still works as there is just contact but I have not had time to do that yet. I had one more short run to do, only a half hour job, so I set off. Initially I found that my clutch brake adjustment had worked and it was easy to engage gear. Then there was an unusual noise from the gearbox and for a second I thought that I had lost the drive but it came back. But the transmission first gear was now noisy, not broken cog noisy but perhaps bearing noisy, and there was an improvement in second gear and even better in third, which sounded normal
However the clutch brake is not working at all now and I was wondering if the brake band had broken off and fallen into the gearbox. Is this even possible in theory. The white smoke may have been from the band disintegrating. The gear oil looks fine and no sign of debris and is up to the full mark and is nice and clean looking
I drove her all the way back to the yard about a mile in third with no incident, reverse is also fine. Any ideas before I start taking things apart?
