Sticky shutter on 80mm Mamiya lens

[Douglas1]

I have a lens for a Mamiya C330 that has a sticky shutter. I've read that some people have fixed this problem by applying Ronsonol lighter fluid to the shutter blades. I'd like to give this a try.

To do that I believe I'll have to take the front and rear lens element off. Is this correct? If so, I might need a spanner wrench to unscrew them. I don't want to buy a spanner rench for just one job. Any ideas on a substitute or other method?

Many thanks,
Douglas

First you can damage a lens even with the most expensive spanner wrench $ can buy.
Second real proffs may use needle nosed pliers filed down to just fit into ring slots, or brass blank filed similarly.
Third unlike a uv filter unless you reassemble in a clean room you will admit dust.
Four is sit in from of your fav TV program and shoot off blanks that may free the shutter off sufficiently.
Not stripped a C330 buy I try and only work from one side admits less dust. Use slightly damp camel hair brush to try and avoid turnng shutter in to schrapenel over the deep shag...
