Reading up on it seems that one of the weak areas of the design is the hard tube lines going up in the left rear ROPS support. Fix is to just go back with a/c hoses.

We have an old 4320 here. Used for small jobs ~ disking, chasing & banking. No air con, just louver windows.
Make sure you give it a good clean before you start work on it. Will have years of dust built up every where.
