O-ring for trapping oil in the bladder.
Bleeding Instructions
1/ Remove the cartridge from fork
2/ Remove the TST adjuster using a 2.5mm hex wrench
3/ Remove cir-clip
4/ **** Using a 10mm spanner remove compression valve assembly (42). Use a rotating motion so not to damage the O rings. Alternate version uses a 23mm spanner, see bellow
5/ Pour our waste oil and clean and inspect all components
6/ Re-fill the cartridge using SAE 7.5w oil - cycling the damper rod to expel the air
7/ Fill to the very top and re-install the compression valve using a rotating motion, again not to damage the o-rings.
8a/ For models with an 8mm damper shaft
Compress the damper rod so that the exposed rod measures 160mm to the red nut
8b/ For models with an 10mm damper shaft (Marathon Race)
Compress the damper rod so that the exposed rod measures 80mm to the red nut
9/ Using an O-ring roughly the size of the damper, slide down from the top of the cartridge to halfway down the bladder so the oil is trapped in the bladder bellow the O-ring.
10/ Using a 10mm spanner remove compression valve assembly. Use a rotating motion so not to damage the O rings
11/ Extend the lower damper rod fully
12/ Top up the cartridge using SAE 7.5w oil
13/ Re-install the compression valve using a rotating motion
14/ Remove the bleeding O-ring
15/ Test - make sure there is a film of oil under the bladder to ensure lock-out
**** NOTE: There are two types of TST5 cartridge tops, please take note to which one you have.

ReplyDeleteWhy can't i just turn the Compression adjuster assembly by the 23mm at the top of the topcap?
ReplyDeletegood point, see update
DeleteGood afternoon, tell me where to buy part 43 tst5 and can I buy it at all?
ReplyDeleteHello I believe I have a 09 all mountain z1 looks like type 1 but was unable to remove 42 assemble from top of bladder- had luck filling from the bottom by removing the rebound needle and filling the entire assembly and after putting needle back in it filled up the bladder pretty good- got rid og the clunking during rebound stroke- just thought id share if anyone else was having clunking- i wasnt able to do the o-ring method
