Pro-tip: before driving the oil seal in, use the seal driver to pound the bushings into place. Mine took quite a beating with the driver and dead blow to get low enough to get the oil seal in far enough for the circ clip.

At 13:15 he says to torque the fork piston rod to the cap at 14 ft lbs. DO NOT TORQUE IT TO THAT. The correct torque is 8.5 ft lbs. It cost me $75 and 2 weeks to get a new fork piston rod. I torqued it to 14 ft lbs and the fork piston rod sheared right off. I had to easy out the threads from the cap. Not a fun month....

2016 husky TC 250. This was pretty darn close, and massively helped me out.

Watched this video to do my fork seals 4cs and everything worked perfectly just like the video thank you . And no I didn’t have any oil leak out while bleeding it.

Very well explained, very clear and precised ... William Australia, , 03/29/2022

A tip before parting to fork (wich also stated by ktm) is to heat the outer fork a little (unill roughly 50 degrees celcius) to making parting a little bit easier. Also for remounting, its adviced to heat it up a little bit! For the rest, great video!

What is the amount of oil in the lower part and what amount of oil in the upper part? thank you

[boex]

It would be nice if all the kits and parts would be in the description of this video. All kits, tools with URL for the 4CS fork.

i just took my forks apart and I noticed there was a missing washer the washer that goes under the seals. is only once fork supposed to have that washer? because only one on my forks lol

NEED HELP! Great tutorial, but my manual says 'oil capacity per fork leg is 670ml (22.65 fl. 0z)' how much for bottom and top? I've just received all the tools suggested from Rocky Mt. ATV and anxious to get stated.

[jesseklassen]

My 2016 KTM XC-W has the same for but the top cap is different but I think it's the same procedure with a few different tools

[steveg]

Is there a possibility to make it 50mm lower ? (Scrambler project with fe 501 )

[DuRoma]

Is the same process for the NO 4cs suspension, on the KTM 300 EXC 2015 ?

[joeduncan]

Would the oil level be the same for a 2016 250 SX? Redoing my fork seals and not sure how much on the bottom and top of the fork.

[davidchandler]

On my 2017 KTM 300 XC I used a 20mm wrench instead of trying to squeeze the 19mm wrench in there. Worked MUCH better.

Hi guys
I'm currently rebuilding some 4CS off a 2015 FC250
When I added oil to the lower section and I was pumping the rod a fair amount of oil ran out through the upper section. I added an amount of oil extra (guess) for the amount that ended up on the floor.
When spinning around and adding oil to the top section the rod will not float up by itself. Takes a small amount of effort to push down and stays down will not float up.
Any ideas to help would be appreciated
Thx

My compression side only moves four clicks, whether it is clockwise or counterclockwise. Any idea why that would be?

[ranvirsinghnetam]

HELP !!, guys i dont have access to dedicated fork seal grease so what other grease can i use to lube the seals, PLEASE BE ELABORATE because i use all purpose grease and seals started leaking in a day

[spebizf]

Would these forks retro-fit a 2013 dual chamber bike? I mean same triple clamp and brake and wheel... thx
