Those are the stud sizes, not the wrench size that you need for the nuts.

John,

The Franklin parts catalog I am looking at shows 3/8"-24 and 7/16"-20 for the nuts.  Perhaps they are different between American and PZL Franklins.  Mine is PZL.  I would appreciate any tips and tricks you might have.

You can get the wrenches (pricey) from Susan at Franklin Engine Company.  Or you can buy a set of stubby wrenches and grind them down a bit so they fit in the tight spots.  The special wrenches are needed for setting the torque if you don't have a torque gauge built in your arm like I do.  The Lycoming/Continental wrenches have a similar shape and should work as well.  You need two sizes, 5/8 and 9/16.  Buy a set of pal nuts from A/S in case some of the ones you remove don't tighten well.  I have lots of other tips if you're interested.

I am hoping that in the next few months, I am going to be able to start the slow process of bringing N21HV back into the air.  First on the agenda is a detailed engine condition inspection, reconditioning, cleaning.  I anticipate I am going to have to pull the cylinders off to do this and recall reading this magical tool that makes the job remarkably easier.

Now, doing the web searches, there are many vendors selling "Lycoming / Continental cylinder base wrenches" but not Franklin.  That make sense as the install base for the Ly/Con are far greater than Franklin.

Now, the question is, is that just a naming thing? According to Franklin manual, the base nuts are 7/16"-20.  Is that what Ly/Con use?

Thanks in Advance.
