Transfer case, After-market and OEM bearing part numbers.

[mitsubishikid]

I happen to have a blown 22 spline transfer case... the previous owner of my Colt gave it to me, so I decided to rebuild it as a backup unit.

After tearing into it I discovered that the Tcase was in better shape then I expected apparently the bearings are wasted, but the housing and gears look to be still use-able

as I tore it down I started to see bearing part numbers on the cups and bearings, so I decided to write them all down, and share them with members, just in case you want to order everything in advance to do the job.

Above is a Mitsu CAPS image I'll use for reference.

[Number in picture above to reference location] [part number you might be able to cross at auto parts stores] [OEM #]
30461------------------------------------------------- # on bearing[LM67048]# on bearing cup [LM67010][OEM # MD717511]
30453-------------------------------------------------[32010XJ] [OEM # MD723636]
30307-------------------------------------------------[32009J] [OEM # MD718322]
30454-------------------------------------------------[32008XST] [OEM # MR967457 or MD718323]

You might be able to use these numbers to get after-market bearings from Koyo, national, etc.
[I would recommend you try and avoid any cheep china made ones if at all possible]

Front oil seal on T case part numbers [Duralast # 1981] [SKF 11592] [TIMKEN 223014] OEM # MD723202 or MD703735

Rear oil seal, to drive shaft, part numbers [NOK AH1895E], [SKF 12736], Oem # MD701430 or MD701782

I got all the after market equivalent of these, unfortunately some National bearings are made in China[what isn't these days ], and it's hit or miss if you get ones made in, Japan, Germany, USA, Israel, etc.

I went to AutoZone and crossed the part numbers, these should interchange with most other auto parts stores.

CAPS Image number. AutoZone cross reference numbers/ Brand/part numbers
30461------------------------------------ National [A-6] Duralast [SET6]
30453------------------------------------ Duralast [32010X]
30307------------------------------------ Duralast [32009XM]
30454------------------------------------ Duralast [32008XM]

Front oil seal,on T case ---------------- Duralast [1981]
Rear oil seal, to drive shaft------------ Duralast [223240] or [710317] I'm gonna find out which works soon enough.

Hope this helps other members out.

Update: on the Rear oil seal, I have both in my hands 710317 is a little thicker in some places, but its almost identical to the 223240.

Bringing up the dead but it's legit because there's other good info in here.
Has it been verified that 223240 is a fitting match for the tcase output seal in 1g/2g?

The one I have in my case is still good but I've got two 223240s in hand and now wondering if I should keep them as replacements.

I know, I could measure inside bore and outside diameter of the shaft, but I'm trying not to destroy the seal that's in there right now and avoid disassembly.

I also know that the Mitsu OEM parts are still available and cheap at <$10/ea + ship, I just had two and who knows.. maybe some day they will disappear as well.
I'll just try tor remember to add one to a US order when I do the next, and then I can measure if nobody knows.
