penny in gears

[jeremy_283]

i gotta losen up a nut right around my clutch and ive heard of putting a penny inbetween the gears....... but will that hurt the gears?

no, the copper the penny is made out of, is much softer than the gears. If you put a hardened peice of steel, you will damage the gears.

be carefull about usin a penny b/c they are not all made of copper. If you have ever drilled into a penny you would notice its more of a steel color inside. the composition has changed througout the years. Found this on wikipedia the online encyclepedia. If you use a more current penny i would find out if zinc is softer than the steel of the gears.

did you try an impact gun before the penny? When I remove the nut off my clutch basket I use an electric impact gun and it comes right off.

if you do have a 1943 penny, you have a $.01 piece worth a few million.

And if it's a truly copper 1943 penny you may wanna rethink the tool of choice;)

The most paid for a 1943 copper penny was $82,500. That's alot of pennies :eek:

i'm with Kc, put an impact on it, and it'll come off with the machine in neutral without holding the basket in any way.
