If you need any other question answered regarding your CASE Crawler Loader Dozer please leave a comment in the box at the bottom of the page & I’ll get back to you ASAP. Get the machine to operating temperature at an idle check each individual gear the transmission pressure & response time should be EXACTLY the same for each selection. Q: What do I look for when buying a used dozer / loader? Q: My machine has lost all drive & hydraulics!Ī : Flexplate likely is broken – check inside engine bellhousing for debris. Q: Why does one track want to drive even when in neutral?Ī : There is a broken plate in a clutch pack, locking it up & causing it to permanently drive. Sometimes faulty seal rings at clutch pack piston seals. Often oil control rings on shafts are at fault. Why is there a hesitation when I change gears/range?Ī: There is a problem with internal oil leakage on the slower side. Q: Why won’t my machine engage left & right tracks at the same time? eg – two being engaged at the same time (fwd & rev / low & hi on same side) If all clamps are tight & no leaks are present – the problem could be the charge pump itself.ġ) Air flow through radiator / oil cooler restricted with dirt, grass etc.(usually effects engine temp as well)Ģ) Loss of oil flow due to bad pump or internal leakage at torque convertor or transmission clutch packsģ) Transmission oil being superheated by faulty clutch pack operation.
If any oil leaks are present, while machine is parked – these are usually leaks on the suction side of system & need repair. Q: When cold, why does my transmission not engage drive straight away?Ī: Often this is due to a lack of pressure due to the transmission pump sucking air – cavitating. If yours is broken, think about getting it replaced. TIP – Most Case crawlers have transmission pressure gauges – this is a valuable tool for diagnosing faults.
