[TenTec] Disolving pto grease

[Tim Long]

We're starting to see suggestions of some creative solvents and 
greases.  When I rebuilt mine, I saw traces of the familiar green Copper 
Sulphate in the old grease.  The source of copper is obviously the 
brass.  The source of sulphur was probably the cutting fluid that was 
used when the brass was machined.  Be careful you don't use anything 
containing trace amounts of sulphur, either in the solvent or the 
grease.  Good luck.  The factory gets $25 for rebuilding a PTO.  They 
told me that it was roughly the same complexity as rebuilding a 2 barrel 
carbeurator.  If we knew the type of plastics used, we could easily 
specify a solvent that would be safe.
