REFLECTOR: Franklin engine rear seal.

Mon May 26 15:02:04 CDT 2008

This has probably been discussed in the past but maybe someone can bring me 
up to date.

I am having trouble with seal leakage at the prop end.  At first, I just got 
some black grease type goo being slung out the seal area.  Now, it is 
leaking oil and dripping out the lower cowl.  Is there a seal that can be 
replaced?  Can the existing one be tightened?  Is it a job that can be done 
by the average mechanic?  Thanks for the help.  JT
