MrGrumpy83 Posted October 19, 2016 Share Posted October 19, 2016 I noticed a wet oil stain on the sidewall of my tyre yesterday after the bike had been parked for a few hours. I had a look and found a drip on the bottom of the hub. I rode it home and parked it. The oil is actually clean (it shows as black in the photo but it had collected dirt on its journey to the low point to form a drip) and is very thick and tacky and has a similar smell to car gearbox oil. In fact I'd say it's so thick that it can't possibly be oil, has to be grease - how it's forming into droplets I don't know. It appears to be originating from behind the hub assembly, around the area of the chain tensioner. Has anyone seen this before? Any tips on anything simple I can do to get me by until I can get it in to Honda? Bike has ~16,000km. Link to comment Share on other sites More sharing options...

Member Contributer fink Posted October 19, 2016 Member Contributer Share Posted October 19, 2016 I would say chain lube too. Link to comment Share on other sites More sharing options...
MrGrumpy83 Posted October 19, 2016 Author Share Posted October 19, 2016 Could be I guess, but I can't see how? Chain lube would tend to fling away from the chain when riding and not leak down like that, wouldn't it? And if it was chain lube should there be evidence of it elsewhere? I don't use huge amounts of lube on it, it's not overly 'wet' and it hasn't been done for a few weeks, but yesterday was the first time I've seen the drips and it has leaked more overnight. The pics don't really do it justice at all but it certainly doesn't look to me like it's coming from the chain. Either way it's due for a clean and re-lube so I'll do that and if that's all it is then awesome. Link to comment Share on other sites More sharing options...

dogman Posted October 20, 2016 Share Posted October 20, 2016 Maybe some of the grease in the rear wheel bearing is coming out due to the bearing running hot??? I have never noticed it myself but that is an area that tends to get mucky. Next time after a good ride feel the hub to see if it is excessively hot.

Member Contributer JZH Posted October 20, 2016 Member Contributer Share Posted October 20, 2016 FYI, the bearing carrier is not filled with grease, but it could be liquified excess grease, I suppose. The only way for bearing grease to migrate out of the bearing carrier, though, would be past the axle seals (the carrier itself doesn't have a drain hole or anything like that).

Member Contributer Grum Posted October 20, 2016 Member Contributer Share Posted October 20, 2016 It looks to me as though there has been a pooling of whatever at the pinch bolt head area and has dribbled down the back of the swing arm. Could you have possibly accidentally oversparyed chain lube onto that area. The chain lube I've used for years is Maxima Chain Wax and as you described (smell of gearbox oil) it does have a smell of Hypoy Gear Oil. Does your rear wheel feel nice and smooth when turning by hand? Might pay to clean the area thoroughly then re-assess the situation. Cheers and Good Luck.

Member Contributer Egg on Leggs Posted October 20, 2016 Member Contributer Share Posted October 20, 2016 Maybe the previous owner was smart enough the lubricate the area to avoid it seizing up. Link to comment Share on other sites More sharing options...

It looks like that in the photo, but there's no evidence of that when you see it in the flesh. The fluid runs through the crack in the middle and pools there before running. There's only a little bit around the pinch bolt. I'll clean it up over the weekend and see how it fares. Link to comment Share on other sites More sharing options...
MrGrumpy83 Posted November 14, 2016 Author Share Posted November 14, 2016 Finally got to clean it up and go for a decent ride. Now it's time for some humble pie. It was chain lube. Must have been heavy handed last time around! Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted November 14, 2016 Member Contributer Share Posted November 14, 2016 That's Great news far better than it being a bearing failure. Enjoy the ride. Cheers Grum. Link to comment Share on other sites More sharing options...
