Hello Harle,

Yes, there is a seal at the wingshaft. In the Spare Parts List it is listed as CO1TS 18043 "Packing- wingshaft".

I just checked my old samples and as per attached photo the original packing is on the left, and an "O"ring that was used as a substitute by the rebuilder is on the right.

After 13 years since being rebuilt, there has been no leakage at the shaft so the "O"ring seems to be a good substitute for the packing.

Cheers,

Good Day All,

Slight correction of the previous information:

After looking at a few more Houdaille shock absorbers I seem to remember now that all have the factory chisel mark for the correct location of the arm on the wingshaft.

I am reasonably sure that the centre punch mark shown in the photo is for the location of the indicator arm on the tension adjustment screw. I believe this is also done at the factory where the correct tension in the shock absorber is set on the bench.

I read that somewhere but cannot put my finger on it to confirm.

Cheers,

As I often say "When everything else fails- read the instructions". See attached photo from Maintenance Manual.
Tension adjuster arm points to chisel mark as per Maintenance Manual. It is also in line with the centre punch mark as it turns out. Makes sense as you have to mark both the shaft and the arm for alignment.

Hello
What about the puller that you used for the arm, I tryed different ways with a puller , with heat .....But it is still in place.


Other way I heard that the oil is glycerine oil and could be dangerous by heating?

Thank you
Sylvain
