Need some advice as I am not an expert and know enough to be dangerous. The clutch on this '05 WR450 seems to be either engaged or dis-engaged and I can't find the all impoprtant in-between when hill climbing.
I've read that grooving takes place be searching threads, but found no images so I have attached an image that shows the clutch housing (outer) and clutch boss (inner) and both have visible grooving when under a lights, but are so slight that one can barely feel them by hand.
Can someone tell me if I have found the problem by looking at the pictures please? I would guess the "grooving" is less that .001, but I haven't figured out a way to actually measure them. I thought I would ask here before asking the stealership.
The friction plates (fiber plates) are within spec at 0.119. Manual calls for 0.115 - 0.121. I have not measured the clutch plates (steel discs) because I don't have a true flat surface to use the .004 in feeler gauge as called for. If the discs and plates all look new, what would the chance be that a plate is warped causing the symptoms in comparison to what's in the pic (since I don't really have a way of measuring for warp/cupping)?
Thanks in advance guys.
