Changing clutch on stihl fs 400 brushcutter

Recommended Posts

The clutch has gone on a brushcutter at work, but I can't work out how to actually get to it to replace it! Ive got as far as the photo... Sort of looks like there could be a c clip in there but it's really tight so I'm not sure. Any ideas? Thank you!

It's a while since I did one and that was a 490 but you need to remove the clutch cover from the engine, it looks like you have the machine screws out already, it should pull off.

 

Then as you say you need to release that circlip, it's difficult but doable with a long screwdriver

The whole white assembly pulls off once you've taken the 4 screws out which you have, there is no need to remove the circlip its holding the drum on. Sometimes they are tight as there are 2 location pins in it, where it joins onto the crankcase you can get a screwdriver in to lever it off.

When you say clutch has gone, you mean driving all the time, or not driving at all? 

 

Probably find the clutch shoes are seized on their bushes, and stuck out against the clutch drum.  That will make the front hosing pretty tricky to get off.  It will eventually with much wiggling and a bit of persuasion .

 

Clutch drum bearings have been known to seize, part number 9503 003 7450 or from a bearing factor 6203 -2rs

Clutch springs x2 part number 0000 997 5519
