Control damper repair change out of BMW-Bike-forum to: Navigation, search
That the Dinger leaky will hang from my viewpoint therewith together that dirt remains hanging on the piston pole and damages the sealing through it. I think would be a remedy well a kind of dust cuff buildup.
Heat the screw in the fork bridge unconditionally on 120 degrees C, (248 F) goes otherwise that not out.
Thin fork oil, (ca 60ccm) oil sort 10W 2 wave density rings outside 20, interior 10, tool for removing of explosive ring, a new screw for the fork bridge and
opposite side. (Screw security is also already at it ...)
You may see a muddy pool of watery grease after a thorough cleaning of the part. The wave sealings can be expelled with knocking of a rubber hammer or plastic hammer speedily and easily. There oil will look somewhat dirty.
Remove Segerringe (lock ring or snap ring) and disks and then expel the ring with some beherzten (behemoth, or heavy) blows with a plastic hammer on the piston pole on a side (goes somewhat heavily). New wave density ring imprint slips (have for that a suitable nut taken) with easy blows it very easily purely. Mount disk and Segerring (segerring = lock ring, or snap ring)
Replace first a thread side, disk and ring immediately mount, after that the mother, (prevented the getting through)! would fill the entire with oil, (piston something move, until no more do bubbles come!), would pass a short string to the relief through the second wave sealings and would push it with the thread onto the wave, would remove the thread and would mount the disk and the ring again.
Alas yes I took a normal M8 key screw 2 mothers thereon turned screw into the control damper and the mother against the control damper countered. So I was able to harness that very beautifully in the screw cane and was able to mount of both sides.
The original label of the density ring is QHWA 10X20X7/8,5 VGF01Z03
As of 12/3/2013, a company called Metric Seals, Inc., in Westfield, Indiana (just north of Indianapolis) 317 896-3555, sells this exact part, although they want $27.10 per seal, and I'm pretty sure you need two. (one on each end)
Metric Seals Item #S 10 X 20 X 7/8.5
When I asked them why they charged so much for one seal, they offered to sell it to me for $19, but offered the following as the reason they raised the price so high:
"As these are KACO parts out of Germany, this company now requires a $5000.00 line in order to bring these parts in. They have as the euro exchange rate has gone up and the Europe increase in price structure gone up so has our price. The best that I can do on two pcs would be $19.00 ea." Go to the following link:
Interior diameter 10mm, outside diameter 20mm, height 7mm / height 8.5 mm including. Schmutzabstreifer. The ring has makes therefore an installation height of 7mm and a Schmutzabstreifer of 1,5mm 8,5mm. It concerns a hydraulic pole sealing. Ca. 5 Euro per piece (10/2007 = €16.37 including. Postage), that goes yet yet in comparison with 175 Euro for a new mute. Manufacturer of the Dinger (seal) is Fa. KACO, deliver needs not directly therefore one a dealer.
Type label KACO 73839099
