[Drake] oiling L4B

[W4AWM@aol.com]

Good Morning,

I just recently "serviced" my L-4B and did oil the blower motor.  On mine, 
there are two small oiling holes, one on each side of the motor housing. I 
used 3 drops of sewing machine oil in each hole. ( 3 In One oil is good also) 
 The holes may be a bit hard to get to depending on your dispenser. If you 
have a problem, take a small long shaft screwdriver and drip the oil on that. 
 It will slowly move down the shaft and into the hole.  Be sure to clean up 
any spills or you will have a very dirt ridden spot on the chassis next time 
you do housekeeping chores.  ALSO: Before you begin, disconnect the HV and 
power supply connections, just in case!

While I was in there, I installed step start, power switch protection and 
filament voltage drop mods.

73,

John,  W4AWM
