Hi LawnKing
Yes, just remove the side cover.
This will also help BB assess the condition of the transmission.
I am expecting to see an all-chain drive, similar to the Model 45.
Type 'Model 33' in the search bar (above).
You will find a lot of info there too.
I think this will be a rewarding project for you.
Again, I thank you for the great images of this machine.
