These oils must meet Caterpillar's ECF-1 specification to avoid reduced engine life. Caterpillar list API CH-4 and API CI-4 as preferred oils and API CG-4 as an acceptable alternative. (I can post photos if anyone wants to examine)Īny feedback or assistance would be greatly appreciated.Lubricant / Capacity Notes a. Transmission will have to come out for complete disassembly and further inspection but wondering if anyone can help by identify debris and what to expect as far as damage. No significant amount of clutch material was found in the screen, only a few small pieces of rubber.Īfter seeing the amount of debris on magnets I'm actually surprised this worked at all. Oil was clear however severe contamination was found on the magnets inside the suction screen including 5 small springs, 4 needle bearing rollers, parts of a washer? and other fine metal filings. The following morning, the engine was started and transmission engaged immediately when increasing engine idle speed.įollowing tips found in forums, the transmission oil was drained to inspect the suction screen. Tractor was towed inside shop to thaw overnight. Pressure was observed to drop momentarily to approx 100 PSI when shifting to FWD / REV and to each of the 3 speeds and came back up to 300+ PSI within seconds after shift change. Pressure was verified at the transmission filter cover and found well above 300 PSI. Problem was narrowed down to the transmission since the driveshaft was not turning and there was no loading on the engine whatsoever in any selected speed. With block heater plugged in for 2 hours the engine fired right up but after a brief warm up period it would not move in any direction. Tractor was parked outside for 1 week at 0F until more time available to troubleshoot. Tractor would not move at low idle and engine RPM had to be increased approx half way before any movement.īlade was pushed in against a solid snow bank and tractor was found weak barely spinning tracks on the icy surface (engine at full throttle and no loading). Tractor was started and driven outside for testing and transmission worked in both directions in all 3 speeds. Transmission was found low and was topped off with approx 1.5 gallons of 30Wt TO4. Once in the shop, the hydraulic problem was repaired, engine oil/filter changed out and all fluids checked. Tractor would not move initially but moved with engine at high idle. I pulled it off a trailer upon receipt and managed to start it and drive it inside the shop for closer examination. Engine runs great but transmission has issues. I love old iron and bought this as a repair project. Hydraulic issue is resolved, one steering brake needs work but I now know where to look and what to look for. I recently bought a well used Cat D3B Dozer (28Y series) with known hydraulic and steering clutch issues and your posts have proven invaluable in troubleshooting thus far. ![]()
