Changed the rear end fluid today in the bus, I didn't know the history of the fluid so decided today was the day. I have the bus on ramps made of old railroad ties so it made it easy to crawl under and get it done . I was trying to figure out how I was going to get the gear oil back in and a buddy had this at his shop, sure made it easy ^.^d
Yup, easier than multiple "squeeze to fill" quarts, but that works if you don't have the "heavy equipment".
I just did mine and made my wife promise that if she heard me planning to do it again to say, NO WAY!! (Actually suggested much stronger language.) Four gallons is a lot to pour down a slippery little funnel while reclined under the coach. I even tried a YOUTUBE special garden pump hack. It kinda worked but was slower than slow.
Nothing slicker or smells much worse to me than gear oil.
Dub's wrong, gear oil has a wonderful aroma.
Somewhere in between the slippery funnel and the drum pump is what I call the grease syringe. Harbor Freight calls it their $10 Pittsburgh Automotive Oil Suction Gun. Don't be tricked by the words "gun" and "pump" in the description, it's just a heavy duty syringe. It will get the job done . . . eventually.
I did mine once with one of those small Harbor Freight hand pumps.
Needless to say it took a while and a lot of muscle.
Amsoil gear oil comes in 1 quart size and is in a squeeze bag,easy to put in,have someone opening and one person squeezing.
Yes it will take 20 bags but it's fast.
I've used those hand pumps lots but I prefer the air pumps.
How about burnt gear oil? Really tells you something is wrong.
