likely a bad cooler in the lower radiator tank. Question is, water or coolant? Coolant is death on engine bearings, frankly I don't know about roller bearings. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

| No it's not in the engine supposedly there is some type of liquid getting into the transmission |

Sorry Keith, I wasn't trying to suggest anything was in the engine, just referencing how bad coolant is on engine bearings, but I didn't know how bad it affected roller bearings, typical of the transmission bearings. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |
