B7100 driveshaft tube

[Richsark]

Hi everyone, the tube that protects the driveshaft to the front axle as long ago rusted off, there's just a bit poking out the rubber boot I would like to put one back. I have some metal tubing that will do the job.
But I don't know how long the original was. Can anyone help me with this dimension
Cheers

You need to give more info, there are several versions of the B7100.
Might get you a more accurate info.

Hi
It's a 1981 B7100D that's all I know, just the standerd manual gearbox, oh try this image it may help! Also, can I remove the driveshaft and both UJ's without splitting the tractor. I've just removed the front UJ but the one next to the gearbox looks tricky.
Thanks for your reply cheers

I recently had to split my B7100 for clutch repair. When I re assembled I assumed I could get driveshaft back together after reassembly, but I could not do it. I even disconnected it at the Hydro gearbox (spring roll pin, hard to access), with no luck. I ended up having to cut off a small amount of driveshaft spline to get it together. Now I know it will come apart with splitting tractor. Not sure on yours, but mine would not come off without splitting. My tube also has a seal between tube and shaft at the end near the gearbox to keep crud out of the tube/Ujojnt area. I thought that was a weird if not stupid design for sure.

Mine is split right now, b7100d. I will get you a measurement on that tube later tonight.

Ok, 13.5" long. The end is tapered out over 0.5" to a diameter of 1.805", that makes up the last 0.4" of the shaft. Overall length is 13.5" though for my 81 b7100d.
