Lubricant for rear derailleur

[GAP]

I always make sure the jockey wheels are maintained well.

Well if you look at a new RD and see where The manufacturers have put grease or lubricant or oil - you should ensure there is some there also...

 

There is such a thing as too clean and too dry... Remember typically that the springs and joints probably has grease on it also to keep dirt out as it is doing 2 things - keeping the actual contact point clean and providing lubrication.

 

I think your detergent is possibly too strong and has thus caused you damage through removing all of the protective lubricants.

 

If there is grease - put grease.

if there is lube - put lube.

if there is oil - put oil.

 

Just remember over lubrication is almost as bad a none. but is still better - unless you like replacing stuff.

Mine lasted just over 5000km before it lost tension and had to be replaced.

 

It wasn't the clutch, but seemed to be all the bearings and pivot points.

Never thought I had to lube it...

You are using degreaser on something that comes from the factory with grease on it...

[Reghardt van Rensburg]

Just keep it clean, that's all.

 

You don't want anything that can attract dirt.

 

Do you still have the old derailleur?

No, the shop said that the RD is not serviceable, Actual words was, "we cannot get the RD open to access the springs to replace anything"

 

They've kept the old one.

Depending on how dirty you ride. A good blast of clean water gets rid of most of the gunk. I still have my STX RD on a 1995 Marin Palisades trail. That's done so many km's!. I will remove the RD once a year strip as much as I can clean it out, grease the moving parts with Marine grease and put it back together. WD 40/ Q 20 those are all "solvents" and they in fact dissolve any lubrication. The also act as moisture repellents and do not discriminate between H2O or other liquids and will remove lubricants already in place. In short stay away from these unless something is jammed or rusted in place and needs to be loosened up. Herschels have some really great products and you can get them at Builders Warehouse. http://swifts.co.za/herschell/herschell-specialised-lubricants-2

Marine & Outdoor Grease (MO)

“M” is white in colour. This grease is designed to meet and exceed the extreme lubrication needs of Marine, Farming and Recreation equipment. It possesses unrivalled salt water-resistant properties making it ideal for use on deck parts and equipment. It boasts dependable service life on Jet Ski, bike, bicycle and quad bearings and wheel bearings. It is also suitable for boat and ski trailer wheel bearings subject to frequent water exposure. This grease is an excellent clean grease for house-hold appliances, power tools, tools, garden, and gym equipment.

 

PS. My mate, a mechanical engineer, stopped short of assualt when he saw Q 20 in my hands. He took it all away and told me to rather use nothing on moving parts than a solvent!

Agreed, Clean Green undiluted is a hectic solvent and will wash away all lube. Also Sunlight "soapy water". It is fine to get the part clean but you will need to replace what you washed away. grease, lube or oil

Sorry, another comment, last one I promise, my Dacocrdi road bike still runs on a 1994 Shimano 105 rear derailleur. That has racked up over 30 000km over the past 24 years with only replacing the jockey wheels when needed. No tension problems there. Maybe they just dont make them like they used to.

The LBS are becoming like car mechanics, "We cant fix it but we can replace it" eish!

It's not worth spending 2 hours to fix something, Replace at the customers cost and make profit on the Spare and the Labour. Simple Economics this is why DIY works so well.

 

Derailleur Links can be lubed with a Light Weight Machine Oil. Sprays have mostly solvents and very little actual oil.

[Patensie]

Got a 1989 shimano dx on my diamondback. Never been oiled or serviced or reset. Still working.

 

Have never oiled a rear derailer on any of my more modern bikes & had only one issue with derailer wheels giving issues, that is since 2000.
