Re: Corrosion problem in rear shock.
why don't u go for a diesel wash to remove the corrosion 1st & then use some anti-rust agent like wd40, nulon's, abro anti-rust spray, etc. I make it a point to spray my bike always wid wd40 after a wash.

Re: Corrosion problem in rear shock.
Nope, diesel does not remove rust. The chrome layer over the nickel one already got removed so rust is forming, there is nothing much you can do actually. Hero seems to have a inferior quality control now.Originally posted by chulubuly View Posti've never known about diesel thing mate.will it really remove all the rust patches on my shock ....i have to try it then.thank you so muchI am back!

Re: Corrosion problem in rear shock.
The effective solution to this is that
1. remove the shockers which is a easy task.
2. Scrap out the rust on outside with a sand paper. Use finer one. Sometimes at some parts you may find the chrome coating is good
3. If required go to a specialised shock repairers to get spring disassembled and then spray paint is effective to make it look new and rust free.

Re: Corrosion problem in rear shock.
You can't spray paint chrome, it needs to be electroplated which is a complicated process and the materials used are toxic.Originally posted by chulubuly View PostI am back!

Use a fine sand paper like 150 or 240 grit. Scrap out the rusted portion only.Originally posted by chulubuly View Post
Forget the chrome layer, rust will again form on it. Its better to have a permanent solution like black spray paint. Then rust won't appear again.

Re: Corrosion problem in rear shock.
I have always sprayed wd40 in the inside of the shock absorber covers of my 14 year old bike and they are in good shape. The best preventive way is to use good old plain wax on the coil spring and all metal parts of the shocks and spray the un-reacheable areas with WD40.
For your present condition, if you are a DIY person please go with the suggestions already mentioned by the fellow bikers. I guess the quality of the plating has degraded quite noticeably in the past 10 years. I have seen 20yr old CD 100s with shiny rear mudgaurds without a single blemish!
Getting the chrome to its previous glory after rust has set-in is a near impossible task. One of the most effective way is to clean the rust thoroughly(but gently) and then coat with a good quality paint that suits your taste.Comment

Re: Corrosion problem in rear shock.
Electroplating is costly and you will need to disassemble the shock absorber, which is not recommended.
Use WD40 or some anti rust spray on it. Grease or oil should prevent faster rusting, but nothing much can be done on whats already started.
Alternately you can sell your shocks for scrap or to some local mechanic for whatever price it fetches and buy a new set for about Rs.1900+tax/There are no short-cuts to any place worth going. So ride safe when you are treading uncharted roads.Comment

Re: Corrosion problem in rear shock.
There really isn't much that can be done, now that the rust has set in.
Keep the area clean and do not let grime collect, which will exacerbate the rust by staying damp longer every time the area gets wet. Get the shocks taken off and the mounting points touched up with paint. Diesel/WD 40 will stop the rust, but only until they are overcome by riding conditions. Diesel is lighter than water so it will get displaced quicker, perhaps WD40 will last longer since it is heavier than water.
A frequent pressure wash will help. Essentially, the areas have to be kept clean and dry.Comment
