How much skill required to rebuild shock?

I have rebuilt top and bottom end of 2 strokes, took forks apart and replaced seals, wondering how hard it is to take my rear shock apart and rebuild? Any special tools needed? It’s off a ‘06 yz125, definitely due for some attention and possibly would like to replace bottom bumper. Better off just having someone do it for me as will need them to fill with nitrogen anyhow?

Its not that hard. A few special tools are needed that are not too expensive. Watch a video on youtube and they will explain everything. I was in the same position you were in and did it and it did not take too long. Then just take it to the shop for nitrogen charge.

I just did the rebuild on my 06 125 rear shock. I had absolutely ZERO experience prior to doing it. Found a great Youtube video (06 KYB rear shock rebuild). I bought the pivot works rebuild kit. Also the top nut needs to be grinded to release the peen. As far as tools go, you need a seal bullet and a nitrogen charge kit...I had to go to a local shop to finish this. Take it on bro and save yourself some money.

Its pretty easy until you need the gas

It's not too bad. It's actually easier than forks. I've done mine, then just find someone to fill the nitrogen. It's still cheaper and more satisfying.
I think Rocky Mountain has videos as does YouTube. Use those as a reference.
I'm across the state from you, so if you're bored, I have some(maybe all) of the tools. No nitrogen though.

Yup. if you have that much bike work experience already, you can easily swing it.

Alright, probably give it a shot. Thanks for the encouragement...if it goes bad it's all your fault!!

Just an aside, if you have a mountain bike shock pump, or an air fork pump that goes to 100-150 psi, this will at least let you pump it up close to its final pressure without having all the nitrogen stuff. This lets you seat the bladder and seal head against the circlips and check for leaks, as well as making sure there’s no cavitation as it extends. Just remove the air or warn the shop before they try to fill it.

Just make sure the seal head and bladder clips are seated properly or bad things will happen when you gas it.

Not hard unless you drop the shim stack.

No revalving planned!

So all balls or pivot works "rebuild" kit, what is recommended? Any preference for shock oil?
Thanks for all the help!

Don't get the crap made in China. Any shop can get you the KYB kit through Tucker Rocky part #770663

Have you ever used shims as lightweight washers? I do. Also Indonesian 100 Rupiah drilled are even lighter but a poor quality alloy but work.

Watch the Technical edge dirt shock videos on YouTube.

I've not used them as washers, but I have used them to shim motors to the mounts.

Shock is too easy. Showas require a clip groove spacer thing or you can rip the seal head. Kyb are too easy. Just picked up nitrogen tank setup and pieced the fill kit for 60 bucks

Look for a Technical Touch kit. Please skip the All Balls, Pivotworks, etc. kits.

Look on Youtube for the Race Tech video and the TBT Racing video. Be careful. Wear safety glasses. Getting the compression adjuster assembly back in can be tricky.

Never removed the assembly on the shocks ive done. Worked fine every time.

How did you do a YZ shock without doing that??

|

12/28/2017 6:57 AM

Just like all any other shock. It does take a while for the oil to bleed over but other than that no probs.

|

12/28/2017 7:14 AM

So how do you fill and bleed it? Are you pulling the reservoir??

|

12/28/2017 7:40 AM

Yeah no need to pull the compression assembly out. When it bleeds over from the body the the reservoir side, turn the compression all the way out. It will allow it to move the fluid over faster.

|

Also I haven't watched the videos but make sure that after you put the bladder back in (some oil should overflow when you do), pump it up to about 10 psi or so. That will allow the oil to push through the ports and shims when you out the shaft in the body. Take your time and good luck, it's super easy.

|

12/28/2017 8:07 AM

I feel like the videos online are pretty straight forward. Just follow those. Be really careful with the shims.

Just fill the reservoir and the fluid slowly migrates over, maybe 10 minutes, then over fill the body . After running the shaft up/ down to get the air out , push seal head down and the fluid will run over. Done. And yes compression adjuster opened all the way .

I recently started doing my own and have had great success so far. I’ve reached out to a few members on here for advice (thanks Brian and Bruce!), and got my own nitrogen tank set up. I just bought the race tech fill tool since it simplified the process of piecing things together, and got a regulator for my tank so I can easily control how much pressure goes in. The RM video online is great, I still use it as a reference all the time.

I say go for it, but like said above be careful when you fill it with nitrogen. I double and triple check the retaining rings on both the piston and bladder side, and make sure I’m wearing safety glasses as well as standing to the side of the shock when filling. The pressure going in is no joke, so take precautions accordingly for yourself and anyone who might be standing nearby.

As others have said, it's definitely doable.

A strong suggestion from me is to wear safety glasses. This is especially important when cycling shaft with comp adjuster out and when filling with pressure.

Let us know how it goes.

On KYB & Showas .... Just make sure you get all the air bled out of the oil...... now my KTM on the other hand dizzy is not as easy
