We have a Case 2050M dozer with a small oil leak coming from the right hand side track drive housing. While running the machine you can see some oil drip onto the inside of the track pads. Included a few pics to show where this leak is coming from. Almost looks like there is supposed to be some sort of plug in this small hole? Or could this possibly be a breather?
Is the oil coming from the small hole? it looks clean at the hole but maybe you have cleaned it?
