Hi Adrian351, and a warm welcome to the forum. It's always nice to welcome another Scott Bonnar Model 45 owner on board.
I am glad that the videos Joe Carroll (moderator and Victa guru) and I made helped you...I know Joe and I had a lot of fun making them!
Re your questions;
Q1. When the cutter clutch handle is in the disengaged position, the cylinder reel should
not rotate.
Q2. Unfortunately, this subject is not covered in the owners' manual and as I have never had to remove the drum clutch, I am unable to answer that one. Scott Bonnar, to my knowledge, have never published a workshop service manual for the Model 45.
However, many of our members here have stripped their machines completely and re-assembled them successfully, and may chime in here and give you some advice.
Q3. The set-up of the cutter clutch is a different matter and in fact quite easy to do, once you set up the location of the clutch assembly on the engine PTO shaft. (ie. the distance between the crankcase of the engine and the inner clutch half) You may glean some good info from the thread
HERE which addresses this in some detail.
Re: the bottom blade issue, have a good read of the thread
HERE and in particular post number 15497....this mentions the fact that both the reel and bedknife are sharpened to suit one another; in other words you don't replace one without sharpening the other to suit. Plus the fact that the machinist/engineer will supply and fit a new bedknife for you when you get the reel done, if necessary.
Looking forward to seeing your pics...
Once again Adrian,
to OutdoorKing.
