I recently bought a 440 skid loader, recently had chain case fluid changed and serviced. I was using it to move snow the other day and it started to whine when lifting the arms with snow in the bucket. It lifted slow and was also jolting a little on its way up. I'm wondering what could cause this? It has an aftermarket engine in it and until I fix the exhaust system, the exhaust blows into the engine compartment and near some hoses and the oil cooler coils. Could that possibly cause the issue? Could it be the oil level or the oil filter if it was not changed?
