For the Yak 52 owners that are unaware of the hidden elevator roller in 

the tail cone of the airplane, attached is a photo of a severely worn 

roller.  Most of the rollers are phenolic.  This one is metal. The flat 

spot is caused by the roller binding and not being manually checked for 

free rotation periodically, then lubricated to prevent binding.   When 

this roller binds up, the cable movement across it is like a sawing motion.



Ultimately what can happen is a frayed upper elevator cable. Needless to 

say, not a good thing.



If for any reason you find the hidden elevator roller binding in any 

way, replace it immediately.  Call Jill for the roller.  She usually has 

them in stock.  Replacing it is literally a one-handed job.



If you don't know where this roller is located, email me and I will send 

you a photo of the location.

Dennis

Dennis,

     Thanks for the heads up.  Mine's in the middle of a condition inspection and the bearing is frozen.  No damage to cable evident.  Hoping a little Mouse Milk and time will loosen it up.  Otherwise, anyone know of a 35 pound midget with six foot long arms?  I assume the Russians had a handy supply of them on the production line....

Mark,

If it's already frozen, bite the bullet and replace it.



I've never found the 35 lb midget with 6 foot arms.  The only way I've 

been able to remove it is to place asmall vice grip on the nut and turn 

the bolt head with a 1/4 drive 8mm socket and ratchet.  Just sheer the 

cotter pinand push it out of the bolt once it is removed. When 

reinstalling, be sure the guard is clear of the cable when tightening 

the nut/bolt. This is very important so as not to cause the cable to rub 

on the guard.  You'll need a 1.6 mm cotter pin or a metric lock nutto 

replace the castellatednut.

Theirs was a Three foot tall midget with 12 inch fingers! 

There is a guide that fits on that pulley too. If the bearing becomes frozen the guide can saw on the upper elevator cable too.
