I have recently acquired an H55F and T-case for my FJ-60. It came with the oilling tube already installed. The PO used a soft line that looks like it should do, but I was wondering if there was any reason why he didn;t go with hard lines? Is there any down side to using hard lines for this application? There is a good shop near me that bends lines for most applications so that should not be a problem. Maybe a stupid question but I wanted to make sure before I changed it.
 
if you mean the line that conects the two fill plugs...
you should take it off and fix that busted seal!
just my opinion, but much easier to do before you install the tranny/ t-case into your truck.
good luck, carl
 
I would replace the seals while you got it out.
 
Below is what my tranny t-case looks like.

I always thought that one reason the line was installed was to ensure proper oilling of the OD. I guess not. So part ref# 38111S above is the proper oiller? I guess I need to tear it apart and check things out.

That is the MAF line to use when the seal has failed. It has nothing to do with the 5th gear, which is oiled by the internal oiler cup.

You need to take the transfer apart, and replace the big seal at the transfer case Input shaft (same shaft as the transmission output shaft). I thought you had already rebuilt your transfer?? if not, now's the time!

This is the seal you need:

Past april, I put out this seal when I bought the MAF oil retunr kit, not problems yet with this ..
 
Andrew,

Yes I did rebuild my t-case but this is a different one. This one has different gears in it. I am now planning on tearing down the t-case, checking things out, and changing the seals. Up until yesterday I thought that the oilling cup everybody was talking about was the line from fill plug to fill plug. That's what I get for previously primarily owning TLCs with autos. :doh: Thanks for the info guys, you may have just saved me from faillure in a remote area down the road.
