Wondering if Anyone would have some insight to this problem, my pt50 has a bad vibration when moving forward, had it lent it and when i got it back it seems to be vibrating fairly bad when moving , when stopped and reving the motor and working bucket hydraulics no vibrations can be felt at all. machine has 1250 hrs and tracks have 200 hrs on them, any ideas appreciated , thankyou
Have you checked track tension, and that there's nothing caught up in the tracks?
i took a quick look and tracks seemed fine , installed tracks myself and everything was fine , i remeber my old tracks getting too loose and it never had a vibration like this , you could actually hear the lugs popping as they slipped under load and skipped the drive rollers, tightening them up that time and all was good, i will hopefully be able to take a better look this week at it , still looking for ideas
Have someone drive it forward for you and look at it. Maybe you can see something from the outside that you can't see in the operator's seat.
Can you isolate it to the left, or right?
took a better look last night, put er on jack stands and ran the tracks, cannot isolate it to ethier side, thinking maybe its the tracks sorta like when u dont rotate yr tires on a 4x4 truck, they seem to have slight humps in them, well have to haul to job sites now instead of driving 10 blocks or so away which sucks, cant beleive tracks will go bad with so little hrs, dont use the machine much but when i need it, i need it, kinda sucks..................
I find it hard to believe that is the problem. I am missing large chunks of my tracks in several places and they have visible wear on the ground contact surface opposite of where the drive sprockets ride on the inside. I have no unusual vibrations.
Only other thing I could think of is that something might be wrong, in the drive roller cage, like a foreign object trapped in the drive roller cage. have you checked for that?
Just checked the cages they seem normal, i do have a squeaky bearing though , think its the passenger rear, have a new one here but no time to put in right now, the rear wheel was not wobbling though , ill have too reallly pressure wash it good in a few days and see what happens and take some pics of my track and post
