Hi everyone
looking for some other thoughts, have a couple older stone construction equipment rollers,
our 43 inch roller (SD-43) lost its vibration on the drum, ended up it stripped out the splines, no big deal got it rebuilt and back together
took it out for a test and works great
until one of our guys went from full reverse to forwards rapidly, got a weird chattering noise, almost sounds like i piece of tin catching on a fan blade (not that)
jacked the unit up and tried it under no load, no noises being as aggressive as I could smooth, put it back on the ground, and retried it thinking maybe a air pocket, no dice,
no noise going from forwards to stop, just reverse to stop, have to be at minimum half throttle
nothing appears to be loose to catch anything rotating
thought maybe a brake but the machine is a hydrostatic transmission and the only brake is on the drum, and sound is coming from the rear half of the machine
seems to be that the wheels are still turning a bit and forcing oil backwards through the motor but that doesn't make a lot of sense
with stone construction products being defunct now support is limited so any thoughts be appreciated,
