BTW, unless that pinion seal is gushing oil, I'd put my efforts elsewhere before dealing with a "wet" seal. From what I saw of the airlines on the drier, that is much more likely to either get you shut down by DOT or leave you stranded. A damp or wet pinion seal that is not soaking the brakes with oil might get a mention on a inspection report but will not leave you stranded. You can check the oil and top off as needed, but a bust air hose leaves you dead in the water. Also, how did you make out with the fueling issue? was that fixed when you replaced the hose, or are you still running the electric pump?

Torque multiplier and a 1/2" torque wrench. That is how I do mine. Torque multiplier has a chart showing input (torque wrench setting) for desired output.

It is a working truck and I have bought numerous tools that have been needed to do the work.

Not off hand.I will be out at the truck tomorrow and I'll see if there is a number on it. Paul

lt says it happened in NH, Manchester has a Lake Av. .....Hippy

Wow. I see this man's true colors. He's a violent troublemaker, not the sweetheart ICU nurse. .

I have watched YouTube videos of rebuilding a Mack. Yes, straight cut gears just like the early 9513 that whined horribly. I can't see why the OD would cause more whine? I would say the tip turbine is making more whine then the transmission. I have a 5 spd outside covered in a foot of snow right now.

You know if it’s a working truck just chalk it up to business expense I believe that’s what he was asking in the first place can I do this myself?

Do you know the part number for the tee?

Yes, I was also thinking that how is he going to torque? It might be by the time he gets done renting tools you might as well. Just have somebody do it.

I have a gun that will do it, but you still need to check it

Its safe to say ya'll saw the news story where Ilan Ohmar get sprayed with a liquid... I thought she was tough when she charged after him.... Then I thought, 🤔. So this guy looked weird sitting in the front row anyway..... It turns out that the suringe he used had Apple Cider Vinegar in it... This was staged to look like something bad.... i guess we will see.

Yes, I was thinking the very same thing about trying to do it with a big hand socket bar. That’s why I suggested air but yes. I guess in both cases you have to hold the yolk real tight with something getting somebody in there to give him a hand might not be a bad idea. I don’t even know if an inch drive air wrench will take out 600 pounds torque.

This picture is from blizzard of 78. You can see a Mack DM or U model pulling a tanker, a Terminal freight GMC 9500 and a ford Louisville all stuck on the highway somewhere.

Just on the TV news. Supposed to start 0600 Saturday morning and by all day give us about 2 to 4 inches.. That will be a major blizzard for these people in the south.. Probably will not get any plows out until Monday??? I will sit home and laugh at them!!

If he does use an air gun to remove or install the pinion bolt/nut, he needs to have the yoke held tight so that it does not hammer back and forth with the rythm of the air gun, otherwise he will risk damage to a gear or bearing. The intense backlash of an air gun can do harm... and his final torque needs to be done with a torque wrench if possible..

yup thats what it looked like every where ,,,,entire north east

im sure your going to need a huge air wrench,,,good luck

wow man what a cool story,,,,,dynamite job on the rims and tires,,,,,,have a ball with it,,,hell id be happy just to have that pickup you pulled it with,,,,i had a 70 6ft fleetside back in the day when everyone had them i really liked it bob

Ok. Well as far as the seal housing goes, it should be easy to remove, the gasket is likley avaible, but you can cut one out of gasket paper, . Once you get the yoke out you will see if you need to do more.

Blizzard of 78 wow, who could forget that I was working for Nissan’s back then by the time the bread was ready to roll. We couldn’t move our trucks. They sent us all home. Good thing I had four wheel drive and a snow plow. I don’t know how anybody else got out of there.

I’m sure there’s real thin shims between the ball bearing and the yolk that you don’t want to lose ha ha that’s about all I got

Yeah, same here pretty familiar with auto repair I usually have to get advice from here myself

not with the truck right now for a pic. I am familiar with that method of removing the seal. Just trying to get all my ducks in a row for when I do this job being when I have the truck at the shop I don't have my personal vehicle available whereas truck is staged at a different location for work
