Our undercarriage mounting frame stops were not allowing LG08s to go overcenter! Gear collapse waiting to happen. One was just at center and the other under center. Needed to grind stops where the cap on the tube was complete gone. Purchased from McMaster some hard durometer polyurethane rod that was Reduxed into tube for correct length, then made a tube that went on OD of tube out of 4130 that is bout 1/16" shorter. Then put a 3/16" screw through whole mess to make sure. Thus there is a slight cushioning but max. overcenter things could go is 1/16". Look up in archives details from Ron Parigoris and Steve D. on subject.
