Hi,
I recently purchased an old PC 220-5 excavator. The old girl has 11000 hours on it and besides rust here and there appears in good condition.
All digging and swinging functions work well and have plenty of power.
The one small problem is the machine lacks power when walking / tracking. It feels like it is struggling - whilst the motor is revving fine, the tracks don't seem to have much power. It walks ok on 100% level surfaces, but the smallest incline sees it struggling. A friend who is an operator used it on the weekend (I did not mention the problem to him) and he said "its a great machine, but lacks a bit of power when walking", which says I an not imagining things.
When the tracks are lifted of the ground (by using bucket sideways) the tracks turn fine.
Both tracks and been checked and are not to tight, they were backed off slightly to be on looser side of the correct adjustment. I have checked the oil level in both track drives and they are fine. Tracks are in reasonable condition and all other oils have been checked.
The machine is still very usable, but I don't want to ruin it, or end up giving myself a huge repair bill by doing damage. So I was wondering
1) if I continue to use it is it likely that I can do further damage
2) what the likely issue is - hopefully something simple I can replace myself.
Thanks
