Showa 47mm rebuild question

Recommended Posts

Hi,

I tore down the right fork let to note the stock shim specs.

Also changing the oil, after bleeding the damper cartridge the manual says to make sure the damper rod extends out when compressed.

My question is how quickly should this happen?

Mine seems to slow down at the two inches. It will eventually extend all the way out it just takes approx 20 seconds for that last inch or two.

Is that normal?

Thanks.

It is cold today 36 degrees.

I think the ics seal is leaking.

I'm going to rebleed and check it again.

I'll bring the fork inside so it's warmer.

When I cycle the rod I hear some air inside that I did not hear when I initially bleed the cartridge. I also had a bit more oil come put of the two holes on the top.

So I bled the cartridge a second time and the air was all out, once I performed the full dampening rod compression to purge out the excess oil I introduced air to the system.

It feels OK, and it does extend all the way out, but I can hear an air noise inside as I am compressing the rod.

Is that normal to hear a noise? it sounds like air.

Thanks.

You shouldn't hear anything except the oil moving through the piston. Are you letting the cartridge set for 15min. before pushing the compression assembly in. It takes a while for all the air to rise out of the oil, especially if it is cold. Otherwise you could have an oil seal leak which could be the large o ring around the floating ICS piston, the seal in the ICS piston or the seal at the base of the cartridge (check for oil in the damper rod).

I let the cartridge sit for a few hours with the cap off.

Is is possible to push the rod in too far?

I pushed it until it bottomed out.

I have no oil on the damper rod.

The air seems to be when I perform the excess purging of oil.

Does the ics valve has a seal on the inside, soething to seal it against the shaft that runs down the center?

I will try the other fork leg and see what I have on that one.

yes it does. If your rebound rod fully extends on it's own your good.
