[R-390] Megacycle Change Detent Lube?

[David Austerman]

My detent spring wore through and I put a few washers to move it out a mm or two. This just brought a new un-worn part of the spring surface in contact with the detent and there is plenty of room to do this. Works great. Many people have probably done this. Saved me from finding another spring altogether. Dave

If I remember right, this is one place the manuals call for grease.  I  
use "One Grease" from STP, the grease version of the Teflon-containing  
One-Lube that's been suggested here in the past.

A possible cause of the grinding is that the detent spring has been  
worn to the point it has sharp edges rubbing against the detent  
wheel.. If this is the case, you need to replace or repair the detent  
spring.  Otherwise, the detent wheel will become worn quickly and  
scraped away.
