Model T Ford Forum: Forum 2017: TT Ruckstell, where to fill.
Top of pagePrevious messageNext messageBottom of page Link to this message  By jay on Sunday, March 19, 2017 - 04:47 pm:

'26 TT truck.
A newbie just being sure and wanting to learn.
Using 85-140 gear oil per Forum posts.
The manual says about 2 quarts but doesn't show the fill location.
There are 3 close up plugs.
Plug A: at the top on the end cap of the worm shaft.
Plug B: at about the middle edge of the right differential housing.
Plug 3: drain at the very bottom of the right differential housing.

Do I fill at Plug A or Plug B hole?
Thank you.

Fill to Plug B using Plug A.

Or just put a little bit in A to lube up the thrust bearing and then fill directly in B. You'll want to keep the level just about an inch below the level of the B plug.

I don't think plug A was meant to fill the rearend, at least it wouldn't on my TT. I think it's just meant to lube the thrust bearing, as Justin said. I got a street L and screwed it in the filler hole(B) and filled it that way because all I had was a gallon jug of lube and had to poor it in. Then, removed the L and replaced the plug. Dave

Justin and David are correct. My TT is an early one and does not have Plug A. I just wasn't thinking. :-(

David is right about the fact that it can be a little difficult to get lube to go in the Plug B hole. I made up a gizmo using a small funnel, a piece of tubing and a hose clamp. It works pretty well.

Flip the truck over and use the drain plug ? :-)

I didn't flip the truck over on its topside, didn't want to get the roofing material scuffed. Instead, I removed the entire driveline using pliers and a hammer, left both wheels on for balance, stood it up on the driveshaft, don't own any wrenches to remove the plugs, instead drilled a hole in the left axle tube and filled it with a gallon of 2 stroke engine oil, duct taped the hole so the oil won't leak out. But now I forgot how to put it all back together...lol lol lol :-) :-)

Put a little JB weld on all the parts and stick them together. No tools needed.

I leave the street 90 in the fill hole for easy filling later.
