PTO seals leaking, replacement info needed

[trider]

I have been taking my newly acquired deuce on short drives then checking it over for leaks as I have fixed several fuel and oil leaks on it since I bought it. I have been driving it the last few weekends with no leaks until today. I came outside this morning to find two leaks under the truck. The smaller of the two leaks it comes from the rubber boot on the right and it appears both of these rubber boots need replaced but I do not know what they are called to try and find replacements. Will replacing these rubber boots fix this or is there some other problem I am not seeing?

You need to replace the seals on the shifting rail in the pto

Can this be done from under the truck without having to remove the tranny?

 

[73m819]

YES, will need to drain the trans

 

[trider]

So to be sure I'm understanding I need two front shift shaft seal ie: TIMKEN, NATIONAL #471538 and two boots and that should solve my problem?

 

[73m819]

Should, check the shift rail, if pitted or scared, replace it, the seals will not completely seal if so.

Anyone have any instructions on how to replace these two shaft seals from under the truck or words of advise? I will be sure an inspect the shift rails as well. Thanks for that heads up.

Buddy... You will NEVER stop all the leaks. It will make you a madman.

I know this is true but figured I might as well fix what I can that doesn't required a major tear down and isn't very costly. This doesnt sound too bad but I dont know exactly what is involved so maybe I am wrong. I know its a MV and will always have some leaks and seeps.

The boots to be clear are there to keep dust, dirt ,mud, water away from seals and shaft.

Instructions likely could be found in the TM.

Deuces don't leak, they just mark their territory.

If changing the seal from under the truck do you remove the shafts? I would think it would be hard to install the new seal with the shafts still installed.

Which TM would I look under to find this?

Remove everything attached to the shift shaft?: YES; remove the shift shaft?: NO, you really can't... without pulling the whole PTO-unit.
Just pry the old seals out, clean/ inspect surfaces and install the new ones. Careful, the shaft material is soft steel - not hardened.
TM's #?? TM 9-2520-246-34 and -34P

TMs are broke down in series and numbers. If the last number starts with 1 (10, 14 etc) its an owners manual. If it starts with 2 (20, 23, 24 etc) its a unit maintenance manual. If it starts with 3 (34, 35 etc) its a depot manual. Each level covers more detail. If that number ends with a P, then it's a parts manual. Start with the -20 then look at the -34. Specifically I would stay with the TM 9-2320-361-xx which is the 361 series (as underlined). Only 5 books to navigate through.

TM 9-2520-246-34 does cover replacement of the shaft seals but with it out of the truck and disassembled. If I have any questions along the way I will be posting for help. I will get two new seals and boots ordered this week.

I literally just did one of these and although it's a pain to have to reshim the PTO, there's no way I'd try to do this on the truck. Take the PTO off do the job on the bench and then reinstall. I've had multiple trucks come out of the service that weren't shimmed properly (I've had at least half a dozen that weren't even shimmed: They put RTV sealer on and that was it!).

Also, don't damage the small rings that retain the boots. Make sure you're buying the right seals: The seals have to be .25" height and a lot of people are selling seals that are .28" or .30", which won't leave enough room in the bore for the boot retaining ring. When I went to NAPA and tried to order seals, the correct seal # superseded to a different seal that was too tall.

I recently did a clutch job, so naturally, I replaced all the seals in the Tranny & PTO. I had noticed that I could not put the winch in its 2nd gear, and just thought that it was an adjustment issue. Once I had the PTO on the bench, I realized the the PTO shift shaft had been installed backwards, because the detents would not line up for the shift points.
