great video, thanks, my 55 tst2 forks make a real clunk when I lift the front wheel or olie, thinking of pulling them apart for the first time, have you got any ideas? is that likely to be the same problem you were having?

[blumpher]

@parkemnz some of the forks with the lower specs do clunk and it appears you can;t do anything about it? I'd still give them a service as they are easy to pull apart and you know it's ok then....

Hi I your vid was really helpfull but I have a Q.

How much oil goes into the rebound cartridge which viscosity? In marzocchi´s page, it says thar 150ml in left leg and 10ml in right SAE 7,5. I dont think they are including the cartridge there.

Thanks

[blumpher]

@nohtog yes, marzocchi's page wasn't very helpful. I just filled the cartridge fully with 7.5 w fluid so it operated smoothly, with no gurgling.

Hey blumpher. Would you be able to comment on how to rebuild the ATA cartridge and TST cartridge? Specifically do I need to add some oil inside the ATA cartridge?

Great vid. Used it to rebuild my XC 700 fork. Almost exactly the same. Couple of minor differences but thanks so much!

[blumpher]

@zsvara never seen those bits, unless it's the cartridge inside this one. I'd take it apart and see what's inside. Is the ATA cartridge travel adjust? sometimes these are air or just turn a preload device...On this fork I had to fill the cartridge up to the top with oil to get the damping nice and smooth throughout the travel.

@5niran5 I've fully stripped my 2005 66 rc2x version ...and changed the seals. have a look through the other videos I posted, it's in there. Good luck, it's a very satisfying job to complete..."!

hey, great vids!

i want to service my 66 RC3 2009, is there any guide on how to do that?

is it different from your "Marzocchi 66 RC Oil Change" video?

could you give me some tips and pointer on how to do it?

its going to be my first service :)

thanks in advance :)

Hey blumpher. I took the plunge and opened up the TST. It's a bit more advanced than the TST from the XC 600. It's mainly the upper piston. Almost like a sealed chamber. The oil looked at a decent level but I added some 7.5wt to the 2.5wt anyway. It's like butter now.

Cheers!

@blumpher The ATA is the air spring (Actually my fork is the XC 700 only diff I see is the Micro TST and the location of the units i.e. ATA is on the right leg) and the TST is the oil damper you showed in this vid.  You used oil for the damper was it 2.5wt? I want a real smooth compression do you think I could get away with 7.5wt?

Cheers!
