M813 axle boot and seal job, Socket Sizes needed?

[SFCBush]

I ordered boots for my front axle(1970 XM-813 5-Ton), and had planned on replacing them without disassembling the hubs. However, after getting 2-3 coffe cups of gear lube out of the bottom screw on one of the brushguards, I am going to back out of the job and get set up to replace the axle seals also. TM 9-2320-260-20 shows how to do the job, but the TMs don't say anything about needed tool sizes.

What size/type of socket is needed for the inner and outer adjusting nuts? Are they just very large off the shelf sockets or something special? Where do I find them if they are not off the shelf?

I've seen reference to the need for a slide hammer type of seal puller, any other tools needed that might not be in an average tool box?

Thanks.

4-1/2" and 4-15/16" for the wheel bearing nuts.

a slide hammer puller works well for pulling the axle tube seal and retainer out.

a older thread titled "slight issue with XM818" has a few pictures of the process.

Thanks for the reply

Wow, I'll need to scrounge those sockets up somewhere, don't have anything even approaching those sizes.

Thanks again

at the top right of this pic is the socket that i use.

its 3 sockets welded/bolted together.

one end fits the outer nut and the other end fits the inner.

its nice as the extra length allows good access even when doing the hub with the duals still bolted to the hub.

the tire tool handle is used to turn it.

Torque on socket?

The TM wants 250-400 ft/lbs on the outer nut, those wheel nut sockets can do that without rounding out? Or do you finish torquing it with something else?

that is what i use. they will take whatever you can put on them with a 3 foot bar.

I don't know if the 5 ton is the same or not, but a pipe wrench is what I used to remove my spindle nut. Worked great!

Kevin--I will loan you the sockets---you bought two tires from me if I remember right---groundog

The sockets are 4-3/8" and 4-7/8" eight sided sockets. I found them at toolsource.com, part numbers 1917 and 1919.

Thanks for the offer, I'll be needing these again though, so I'll be trying to locate my own set first.

Thanks for the part #'s, that will save a lot of time, I'll give them a call.
