How the heck do I pull this part out.

[BJH324JH]

I'm disassembling the KM-145 transmission and I am having a difficult time getting this last few pieces out. Any help would be appreciated.

Look at this StarQuest thread found by xboxrox. It mentions and illustrates how to remove the countershaft.

I saw that and he doesn't seem to have photos of the very thing I need help with.

If the issue is removing the synchronizer ring, from your picture it looks like the outer race of the rear countershaft bearing is still in place. The StarQuester removed both front and rear. That must have given him enough room to displace the countershaft and wiggle out the ring. If that doesn't do it, remove the main shaft center bearing.

Here's a video of someone disassembling a Ford FM145 which has Mitsubishi internals and the steps look much the same. Skip the first 20 min to jump to the relevant portion. He uses hammers to remove some bearings. Not sure that's wisest with an aluminum case.

Thank you so much. I figured it out slowly but surely.

Nice work! I’m curious, how are you removing the center main shaft bearing?

[BJH324JH]

Btw, is this the "main bearing"?

[FMS88]

Btw, is this the "main bearing"?

Yes. It's the only double ball bearing on the main shaft.

[BJH324JH]

Yes. It's the only double ball bearing on the main shaft.

Where would one get a replacement for this bearing? Seems like an oddball bearing.

The parts book I have lists MD716917 as the P/N for the center bearing of 87-90 KM145 transmissions. Looks like it's available through Amayama and a few other sources. If the trans is '86 or older, the P/N is MD703729.

[BJH324JH]

Wow thank you. Are you able to share your parts book with us?

Which transmission KM132 or KM145 is in my truck..? Anyone..?

Some trucks have a plate on the top of the radiator support that states the trans type, rear ratio and paint code. If yours doesn't have it, my documentation shows the 4wd trucks with the 2.6l engine have the KM145 trans. (P/N MD715807 for 84-86.) The KM132 was installed in 2wd trucks with different versions for the 2.0l and 2.6l engines.
Look at this site:
https://www.moparpartsgiant.com/part...filter=(T=DDR)
It lists MD71587 as KM145-1 for the '86 Ram 50. (not sure what the "-1" means.)

Thank you FMS88

Only a paint code sticker on my radiator area...

Spoke with a guy named WILL (other shops said Will was the Mitsubishi expert) at this transmission shop in Denver & sent him an email asking for advice & parts support...

My truck still runs & drives but the IMHO sounds like the tranny input shaft bearing is nearing the end of it's lifespan...

As I was replacing seals throughout the transmission and transaxle, I hit a roadblock with this weird seal. It seems to have these raised "locking bumps" on it. I don't know what they are. I believe I found the after market replacement for it. Part number for aftermarket replacement is Timken 224560. Does anyone know if the aftermarket replacement will work properly? Btw, there is two stacked on top of each other. I took one out. The picture shows only one seal, but it originally had two seals stacked on top of each other facing each other. The Timken seal appears to be identical in outer diameter and inner diameter, it just doesn't have those raised spots that the original has.

It is a double seal for the input shaft of the transfer case. The original P/N is MD704164 but that's been superseded by P/N MR145502. Here's a web page for the latter.

The seals are installed back-to-back, or bump side-to-bump side. Behind the inner seal is a thin, shim-like baffle plate.

Also I made a PDF of the parts list. Just need to see if it will upload.

Thank you so much! It does indeed have a thin metal spacer underneath the seal. I wonder why it has those raised bumps on it though?

[FMS88]

Both service manuals I have emphasize the application of gear oil or grease between the two seals. I suspect the bumps are there to create spaces between the backsides of the seals that retain lubricant and keep the seals happy.

Aww, I see. That makes sense. Thank you for the info! Btw, is there a factory service manual other than the typical Haynes and Chilton that can be downloaded?
