Servicing Pike dual air?

Peanut651

Hey, I'm wanting to have a go at servicing my Pike 454 dual air forks. I'm slowly losing negative pressure during rides, it holds the pressure fine when just sitting there so i'm guessing I might just have some worn seals.

Am I right in thinking that the oil for the rebound is only kept in the upper legs of the fork on the compression side and there's only 6ml of oil on the air spring side for lubrication, and there's nothing in the actual lower legs?

Cheers.

Sram have very good service manuals on there pages for all forks with all the info you need.

download and read. dont forget you will need the manual that is older than your forks.

For some reason if you select PIKE it doesn't pull up the oil volume chart, but does if you use SID!

Thanks both. Didn't know they had manuals on there.

I've seen some videos about servicing the pikes, but they already had the lower legs off at that point. I feel competent enough to do the job, just needed the info about the oil.

Cheers.

I did the SIDs at the weekend and have done Rev's before (and Manitous before that), no single action is hard.

Must haves
1/ Syringe for 5ml lower/air spring lube fill
2/ Right oils (lube and damper fill)
3/ Large socket for top caps (24mm from memory)
4/ Deep 10mm socket for removing dual air sleeve nut
5/ Long 5mm allen key for damper side, mine needed a bit to fit onto the socket set for reach combined with torque required

If they are more than 3 years old then the foam rings may well be beyond redemption and you may need a seal/foam ring kit (and new crush washers as well).

Be warned, the old fork oil will get everywhere, it keeps dripping out, I do the job in the utility and thenwash the whole floor afterwards as the floor is like a skating rink when I've finished even if I've wiped up the spills with kitchen roll as I go!

I've got all the tools, if they're not missing lol. I've ordered a full service kit that comes with everything needed like two different oils, dust seals, o rings etc etc.

Cheers.

I used to service my old Pike dual air. It's not difficult, just follow the instructions precisely and keep everything clean. Degrease and thoroughly clean everything before reassembly. Make sure you have an old washing up bowl or similar under the fork as you remove the lowers to catch oil and leave the uppers upside down in it to drain.
