Default Nosedrive Seal question

Freddi'* great adventure: (Stick with me, theres a SC question. at the end.. )

About two weeks ago I threw the SC belt off of the 2000 bonne. After inspection, the Ribbed Pulley had given up the ghost. A quick run to Napa, and some backwards wrenching (reverse thread) and I'm up and running.

This morning, I threw the belt again. This time its both of the smooth pulleys. Upon checking BonnevilleClub, I see one is 3.0" and the other is 3.5". So....me being in a mood to do some upgrading (While I'm repairing) I start checking posts.

I ordered my intense 3.4 pulley. Several posts seem to indicate that if I run two 3.5" smooth pulleys, and the 3.4 SC pulley, I'll increase belt wrap, and not require a belt size change. SInce I have to replace pulleys anyways, this seems to be the best route, unless I'm looking at this wrong. Thoughts?

Now to continue the story, and get to the SC question..... I don't have a rattle in the nose right now, but do have some weeping from the front seal. Logic tells me that If I press on the new SC Hub, It'* going to be tougher to replace the seal? right?

Can I service just the seal, without removing the nose drive, before pushing the new hub on?

Recommendations on whether to go for the Nitril or Vitron on a car with about 70k on the clock?


Side notes: Finally got the OK from the missus to start doing more to the bonne. FWI was ordered this weekend during the Intense sale. Pulley was ordered today, after the belt came off. (Hoping to get an answer to this, soon, so that I can add the seal to my order before it ships) PCM will be next, along with anything else intense puts on sale.

FYI: Already have scanned for KR, and will continue to do so after the pulley install.

Thanks in advance,

Freddi

You can change the seal, and it'* a damn good time to do it. I suggest the Nitrile, as it'* softer, and can conform to irregularities and wear on the input shaft quicker than Nitrile can.

You'll have to drill a couple holes CAREFULLY and slowly in the seal, then yank and pry it out. Try very hard not to get debris inside. Clean it up well. Use a solvent. Then install the new seal and retainer.

Nitrile it is. I assume this seal has a metal mounting ring in it, that is seated into the nose drive? So, I will drill very small holes in it to get leverage to pry it out? (Kind of like a old fashioned wheel seal, just smaller?)

The new seal will just tap in with a socket or other 'device' to make sure it goes in square? What does the retainer look like? Do I reuse, or buy a replacement?

Thanks for the help wren.....it'* SO nice to have resources like this forum.

I'm assuming he is talking about Viton versus Nitrile which, Viton is a harder seal type, and is only suggested in an applicion in which a new seal surface is available.
Nice.
Is it green and supercharged or green and supercharged.

Also, Viton and Nitrile generally both have garder springs installed in them, the only type generally that doesnt is a true Wiper style seal, which is MUCH harder, and is generally used on shift shafts which move in a back and fourth motion
