When you get the nut off don't forget to take the oil dipstick tube completely out of the block. It took me a minute to figure out why the aux shaft wouldn't slide out of the block and it was the dipstick tube stopping it.

Good information Jerry. Thank you for the reply.

Does the oil pump need to come out to get the Aux shaft out and how did you seperate the front driving gear from the splined aux shaft?

I took off the power steering pump and just shoved it to the side. I shimmied an impact wrench (probably not recommended) up there to loosen that nut because the engine turned when I just used a breaker bar.

Thank You for your reply.

If I remember corectly the gear stays in the cover theres a big nut on the front 2 inch or so Shaft is splined to gear. can be done fairly easily can be acsessed behind the ps pump or ps cover block off which ever you have!

Thanks for your reply.

I went through the same fiasco last summer w/my 97. I asked around and the only option given to me was to replace the whole accessory shaft. It's not a horrible job, but a pain in the ass nonetheless.

Thanks for the reply.Can the gear at the front of the shaft be removed without taking off the front gear train cover?

We have a 95 Mack CH with the E7 Engine.The drive gear for the air compressor just spins on the accessory drive shaft.The gear is just press fitted to the shaft.

Is there any known repair for this without having to remove the accessory drive shaft.
