You have to tear the whole case down to swap the input. The case disassembles from the rear forward.

It's easy stuff, prolly unfamiliar to you, but it is just nuts and bolts, take your time. It only goes together and works one way. Take pictures if you dont have a good memory, lay out your parts, in order with a system of remembering up=front etc. Also, prolly the google has some pictures of disassembly...

There is a snap ring on the input shaft that has to come out. Its behind the seal

And a pain in the ass too, there is actually 2 snap rings. The one on the input shaft and one for the front output

I just did this swap but going from an auto to a manual, it's pretty straight forward, it is very important to have a good pair of snap ring pliers!

However, I think you can manage it, and hope the pictures above help... let me know if you got any questions

There are several snap rings throughout the case that will have to be removed during disassembly (not just 2).

Also, while the pictures above are useful, they are not of a 271. The seal has to be removed from the front case half - it cannot be unbolted as shown above, so I would suggest getting a new seal onhand before you start. It is not difficult, just take your time.

I have pictures of a 271 when I tore mine down, so if you want to see something specific, let me know.

I'm a freaking idiot, I just now saw the "271" I read 241 my apologies

They're pretty similar - I just wanted to make the point that the seal is basically destroyed upon removal and not bolted in.

Yes but I've always used an anaerobic sealer. I think I spelled that right.....

jakerc69 · 10-13-2013, 02:12 PM

Lots of people use anaerobic sealer
I like the right stuff by permatex
dodge transfer case and diff silicone works well.
If using anything but right stuff make sure and let it cure before adding fluid....

Penni · 10-13-2013, 02:27 PM

I use the grey silicone myself...

I like black rtv that's all I use, never have leaks with it

On this same subject, has anyone ever seen a 31 spline output for a 47RH?
