One of my tilt plate bolts fell out today.. Where the tilt plate attaches to the lift arm. I put the unit in the shop and checked it out, compared it to the other side. It would appear that there is some sort of bushing in the tilt plate assembly that the bolts threads into. This is missing on the side that the bolt fell out of. What do I need to repair this or how do I re-bush the tilt plate bolt housing ? I did a search for some sort of parts diagram but no joy. Anyone?? What do I need to do? Thanks
