PTO box O ring sizes (1 Viewer)

[Eurasiaoverland]

Does anyone know the size of the O-rings used in the 60/70 (and probably 40) series PTO boxes?

There are two sizes - one for the input gear shaft and lever shaft (3 in total) and one that lives inside the case where the shift shaft comes out of the front of the unit.

Unfortunately they are both 'flattened' slightly in cross section, so hard to match to a specific size. I think the larger one is non metric, BS114 but can't be sure. The smaller one is more distorted, possibly BS112.

NLA from Toyota.

Thanks

I believe the one on the portion that comes through the front of the case should be 12mm.

The two on the idler shaft should be 30mm.

Those are educated guesses based on Toyota part numbers.

Thanks Onur, I was wondering about the part numbers - the smaller shaft is 13 mm in diameter, so a 12 mm O ring might work. The larger shafts are 20 mm though.

Mechanical winch shaft 1979 (info & pictures)

Spent some time for my winch shaft (bj43 1979). Easy start of the shaft restoration. Decided to post some condensed info, might be useful for the new comers.
