Clutch damper spring orientation
Hi guys,
I had my clutch plates out for inspection and when installing everything back I didn't recall the orientation of the 'clutch damper spring'. This is the concave metal disc (says OUTSIDE on the concave side) that goes in second after the first metal disc 'clutch damper spring seat'. The service manual says to install with the OUTSIDE mark facing out - so I installed it with the outside mark facing to the outside of the engine as in to the right side when looking at the motorcycle from behind. Is that correct or would the OUTSIDE mark need to be facing out from the clutch plates so towards to cylinder? I actually tried both but I'm having another problem with the clutch as it is not actuating (no resistance in clutch lever), not sure where the problem is but I will take my time tomorrow so I'd also like to be sure then the clutch damper spring is facing the right way so I won't have to pull it off once more . Thanks in advance for anyone willing to supply me the answer! |

It could be the actuating rod/lever orientated or engaged (with the push rod) correctly. The punch marks should line up when the clutch is fully engaged. Read this thread and see if it helps...

But the main problem I had still exist which is that the clutch is not actually disengaging, I thought it was maybe due to the clutch plates sticking and that's why I opened it up in the first place but that does not seem to be the case. I'm sure the clutch plates etc. are all in the right place at the moment as per manual now. To be clear this problem already existed before I opened her up, I first noticed the problem after I changed the oil + filter. Anyone any ideas? I just cannot disengage the clutch even the slightest even if I fully remove the slack of the clutch lever. Last edited by Jofr; 01-04-16 at 18:59. |

With the rear wheel lifted I could sometimes start the bike with the clutch disengaged in the higher gears 3+. The wheel would not turn but once let go of the lever most of the times I could not disengage the clutch anymore and the wheel would keep turning...
Very strange, I'm left clueless to be honest. Could it be the oil, is the XT 660 picky about oil? I've used the same oil in my XT600E without issues. |

Either way, if you are sure the external parts are all in order (cable, freeplay, lever, punch marks etc.) then you're going to have to resign yourself to taking the cover off and inspecting. The interesting thing is it happened after an oil change. What oil did you put in? It is quite possible that the oil used could have swelled the friction plates locking everything up - the "wrong" oil doesn't always result in clutch slip; a common misconception. I've seen/heard of several sets of clutch plates ruined by the use of "Energy Conserving" oils, just ask SteveD! BTW - contrary to popular belief, the wrong oil doesn't mean synthetic, nothing to do with that, it's stuff labelled "Energy Conserving" (usually, but not exclusively car oils) that are the problem due to the complex additives which reduce friction and cause swelling in multiplate wet clutches; it just happens to only come in synthetic form. It should never go anywhere near a wet clutch. Use only JASO MA certified motorcycle oils suitable for wet clutches, which can be mineral, semi or fully synthetic. |
