Sachs Shock Service

Can you elaborate more on the step cut?

A bit of info here

Had a good read of that. Thanks Matt.

Had a quick read and see what a step cut is (not on LTR site). Any issues with using an angle cut? Either way, I'll have a closer look and try and work out which piston band they have on this particular model.

A step cut is like looking at a set of steps sideon, you cut the piston band down to half way, then across then down so it intertwines when held together.

Cheers.

Yep yep. Worked it out with some light reading Thanks Simmo

Jacobi. I have the 16mm sachs shock seal and the swingarm bearing kit!

Hey jake why do you say it is not possible to vacuum bleed the shock?
How is it different on other shocks? (Pls answer with pics;-)

Thanks Rob, I had some swingarm bearings here and the bushings came up ok after some cleaning. Ended up replacing the tie rod portion of the linkage.

The Sachs shock was really quite easy to hand bleed, and I used the seal head to set the height of the res piston. I also used the vac pump to pull any air from the fluid before pumping it into the shock for hand bleeding.

In regards to the vac pump Matt, you have to be able to fully assemble the shock dry, and then connect the vacuum pump lines to the shock. This means you either need a bleed port (just a threaded hole somewhere on the shock body, ususally near the top eye), or you need to bolt up an adapter plate to the resevoir and fill from there. Using the later way, when completed you remove the adapter and then drop the bladder into the res and allow some oil to overflow and no air is trapped. Due to the Sachs using an internal floating piston to separate the N2 and oil, you can't get it in there at the right height using this method.

Any special tool needed, to hold the seal body in place, while unscrewing the 4 hole seal cover?
There is no way for it to give and it wouldnt be in my interest to scar the body.

Possibly try a strap tool like you use on car oil filters?
