TXT Rear Diff Lube change
I changed my diff oil today. My cart was a fleet cart and they had changed the oil before, then sealed the cover with clear RTV gooped all over. But the oil was dark and had silver shavings in it. So time to go. Diff looked great, so no concerns. Washed the diff out a little with brake cleaner.
I am using Mobil 1 75W-90 Synthetic Gear Lube w/ friction modifier already included, not that the TXT needs that. To seal the cover I used Permatex 81182 Gear Oil RTV Gasket Maker for differentials (special resistance for gear oil additives). Permatex instructions say: Snug bolts up until RTV begins to squeeze out, wait an hour, then torque to specs. Has anyone used magnets on the outside of the diff cover (I am not gutsy enough to put them on the inside) to trap metal shavings? Cover torque specs: Specs are 16 to 24 ft. lb. and tighten in a criss cross pattern (see attached). I snug them up to 20 ft./lbs. which I think is PLENTY tight. These Textron Dana LS installation instructions were finally a place I found Textron to actually give cover bolt specs. |

Re: TXT Rear Diff Lube change
I'm using the same 75-90 limited slip gear oil on the RXV, not quite sure, if recommended on non-LS differentials... a special RTV sealant for any kind of oil isn't necessary in my opinion, waiting for hours before tightening also. What do you think, happens in the factory? They may have 1 hour to assemble the whole transaxle... And, i'm always using the build-in torque wrench in my arm for that small screws used on differential or automatic transmission oil covers ( knowing after tight comes loose.. )
To use a magnet outside the oil pan wouldn't last long, i guess. I know slim magnetic pads used on automatic trannys or magnetic drain plugs. |

Re: TXT Rear Diff Lube change
Does anyone know why the TXT rear end is supposed to be filled with 12 oz. of lube and the RXV with 25+2 oz. of lube/additive? The dana housings seem to be the same in size and capacity, so why would one take twice the amount of lubricant than the other??
