Derailer small spocket bearings oil or grease?
on my Shimano read derailer what lube should I use on the small
sprocket wheels bearings that actually do the shifting part? Oil or grease? Mine were dry so I dont know what to use. Thanks |

Thanks Grease...any grease. I know Peter's a professional bike mechanic and I'm just a hobbyist, but I've had lots of success using just oil. I probably clean and relube my derailleur wheels more often than most, but after a thorough scrubbing I just add a drop or two of Mobil-1 before reassembling. I also discard the rubber seals that sit under the little metal disks, since I find getting them properly alligned is a bit of a pain. They also seem to be a source of some drag, minimal but unwanted. BTW, grease is just oil mixed with a binder. jeverett3ATearthlinkDOTnet http://home.earthlink.net/~jeverett3 |

Derailer small spocket bearings oil or grease?
I took them apart and cleaned them and the chain and the sprockets
on the back wheel. My derailer is a low end Shimano so it did not have any rubber seals under the metal disks..Was wondering what grease to use and found some folks like the grease from the small grease gun I use to grease the sprocket end of my chainsaw. Looks like good stuff, certainly works on my chainsaw. So I cleaned and reassembled everything so its nice and clean and smooth shifting. Its actually a bushing inside mine, maybe fancier bikes have real ball bearings, I dont know. Thanks for all the help. |

try castrol marine from walmort.
i worked the maintenance schedule for the derailleur wheel pulleys up to four greasings a year. that's every 700 miles or so. the interval appears to match the tooth wearout and pulley wheel replacement cycle. listen and you can hear the pulleys scream for grease and the brake pads for checking for sidewall rub |

Actually the better Shimano ones have ceramic bushings which are pretty much self-lubricating. So are the cheaper plastic ones. The main thing is to keep them clean -- shifting suffers when they get gummed up. If you want to lubricate yours, grease is better. Oil will run out or wash out pretty quickly. FWIW I usually put a little grease in mine. Matt O. |

Well, not really. leave these things dry and the inside ceramic bushing will dissolve to dust.Same for the plastic/metal ones. None are self lubing, none are 'impregnated' with anything. Grease is what I use on all pulleys, even the shimano teeny cart bearing ones, Remove the little cover, greaee, replace. If you want to lubricate yours, grease is better.

The main thing is to keep them clean -- shifting suffers when they get gummed up. If you want to lubricate yours, grease is better. Oil will run out or wash out pretty quickly. On the other hand a little oil can be weeped in from the edge every now and then without disassembly. If I must disassemble for cleaning and inspection (periodic) I use grease. At all times in between I use [insert your convenient chain oil here]. FWIW I usually put a little grease in mine. I think that's all you can use (a thin film), since clearance is tight between pulley and bushing. Matt O. Robin Hubert |

The teeth on the pulleys that came with my low end shimano Tourney TY20 wore out after about 15000 miles but the bushing clearance was still fine even though I only used oil. After 30000 miles I am starting to get some play in the upper pivot. 6/7 speed derailleurs don't need the tight tolerances that 9/10 speed systems require ,but there do not seem to be many good low end replacement derailleurs. The stamped sheet metal parallelogram parts on the new low end derailleurs are made out of a thinner gauge sheet metal that will likely saw right through the aluminum rivets they use in no time. Do you need to buy the 105 level of components these days to get durability? |
