My 2007 3320 seems to have had a rough life before I bought it. I've been gradually fixing and replacing parts (and adding attachments of course!) since I got it. The tractor itself is now in pretty nice condition and everything seems to be working well. The 300CX loader, although it works very well, could use some improvements. Several of the pin joints are looser than I would like, and I want to tighten them up. However, buying new parts just to tighten up the pin joints seems like an expensive, and perhaps not necessary, project. I think that I'd like to disassemble these joints, bore out the worn parts, and add sleeves to take up the 'slop'. I thought that the first step should be to buy a service manual for the 300CX loader, hoping that it would include some details about the diameters of the pins, etc. However, I've not been able to find any service literature for the 300CX. Has anyone seen any service literature for this loader? Also, has anyone attempted to do what I'm suggesting?
