Metal_man_Rob Posted February 21, 2021 Report Share Posted February 21, 2021 Found a plastic piece buried in the sweet sweet chain-lube/mud/sand mix all caked up in the front sprocket area. See photos.Front sprocket is junk but wondering if the collar is ok or is this something I should replace.And is this an OEM nut? I am putting a case saver on and switching to the TM chain guides/rollers.The counter shaft seems to have normal play (in and out but no play side to side).The sprocket is worn out, possibly prematurely but definitely in the normal and predictable way.The collar has a groove through the center running evenly around the outside and seems manufactured this way. But it seems to have wear. The not was so loose, even with the lock washer in place and in tact, that the nut was just barely catching the thread. The shaft and splines are all well in tact and show no wear or damage.I can’t think of anything that would cause the nut to loose up so badly. The lock washer was beat to heck but still in tack. Only thing I can think is the busted off chain roller, the shitty ass OEM front chain guide/swingarm bearing guard and a possible shit alignment of the front and rear portions of the chain have allowed the counter shaft to jerk in or out hard enough to allow the splines on the shaft to slip out of and past the splines on the lock washer allowing the nut to loosen over time.Or the shop the guy said he used should consider switching to fixing toy horses for Barbie houses. Anyway... can anybody think of a reason the nut would barley even be engaged on the threads? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted February 21, 2021 Report Share Posted February 21, 2021 That little rubber plug goes in the case in front of the sprocket. Collar is damaged from the seal -replace. Factory nut, was the concave in board? The nut being tight keeps the countershaft from going in and out. 1 Quote Link to comment Share on other sites More sharing options...

Metal_man_Rob Posted February 21, 2021 Author Report Share Posted February 21, 2021 The counterbored side of the nut was against the washer and sprocket. So far I am going to grab a new sprocket, washer, collar and nut. Quote Link to comment Share on other sites More sharing options...
Metal_man_Rob Posted February 21, 2021 Author Report Share Posted February 21, 2021 Oh thanks. Haha. I stared at this schematic before I even posted and couldn't find it. Like where's waldo Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted February 21, 2021 Report Share Posted February 21, 2021 Did it have to proper lock washer? Splines to match the shaft... I've seen many a post and pic where people don't think the nut needs to be tight since it has that folding washer. (and not only self-taught mechanics either) Quote Link to comment Share on other sites More sharing options...
Metal_man_Rob Posted February 21, 2021 Author Report Share Posted February 21, 2021 It doesn't look the same as the OEM washer but it is definitely made for this same countershaft. Everything lines up. And why would someone not tighten it to spec? That blows me away a little. I mean if it was like 12ft lbs and someone tightens to 15, whatever. But so 60 pounds as opposed to 0 pounds... Quote Link to comment Share on other sites More sharing options...

See, I'm helpful dammit. 1 Quote Link to comment Share on other sites More sharing options...
