M1-Series Tanks… Funnel Away Oil SpillsPosted: 2014/15/05
Mechanics, you’ve probably noticed that the M1-series tank’s transmission filler neck doesn’t have a very big opening. It’s just too small to pour transmission fluid directly from the can.
Some of the fluid is gonna spill, no matter how careful you are. And things don’t get any better after that. The oil cooler fans are gonna blow that oil all over the oil cooler fins.
Dust is attracted to the oil residue. The gooey mess that forms on the cooling fins keeps the heat from radiating away from the oil inside the coolers. That leads to transmission damage.
But something as simple as a funnel can prevent all that. A box of 12 flexible funnels comes with NSN 7240-00-559-7364. Never add oil without using one. And get one of these if your current oil funnel is broken or too large for the transmission filler opening.
Each funnel holds a quart of oil. So don’t pour more than a quart into the funnel at a time. Make sure you wipe up any spilled oil right away.
