It looks like I need to service my shaft log packing. I have been needing to tighten the shaft logs more and more frequently, and now the difference between too tight and too loose is about 1/8 of a turn on the nuts so I think my packing is fully compressed.
This will be my first opportunity to try this so I am wondering what I measure to find out what size packing to order. I think it will be the difference between the drive shaft diameter and the inside diameter of the shaft log tube. Is this correct, or do I order material a little larger or smaller to allow for the compression?
Here is a photo of the shaft log (in case I am using the wrong terminology.)
This photo is from my pre-purchase survey, the nuts are now about 1/2" further down the studs.
The engines are Lehman 120, and the transmissions are Velvet Drives.
Thanks, once again, in advance for your help.
