To pack or not to pack... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

This may sound strange, but starting with the input shaft bearing and working your way around, the three larger, visible bearings, do they need to be packed before closing up the transmission after disassembling it or not? I've seen different bearings for the different transmissions for my driveline and I checked out the FSM but it mentions nothing about packing them. It looks as if they should be, but I have not seen any information that says to. Does anyone have any information they can pass on?

Obviously bad things can happen if you don't pack a bearing that should be but what happens if you pack a bearing that wasn't meant to be packed?

That's my whole point. I wanted to ask to see if anyone knew anything and had any advice. I am opening it back up tomorrow and I will be definitely going over things to check. It has been two weeks since I had things open. There has been only minimal driving, so I should see a little something, hopefully nothing at all. Well, if anyone does know whether or not the bearings inside and or attached to the transmission core should be packed, please let me know.

If the bearing is on the inner side of the oil seal, i don't think there is a need to pack it. It should be coated in gear oil when the tranny is filled.

Nope. We rebuilt an Xterra tranny at work, and we did no packing of the bearings.

Thanks Mephisto.. when you finish work today, swing by.. you know where I'm gonna be all day.. Once again, thanks for the information.

As I was right, it was the input shaft seal or I should say, lack there of. When I pulled it, all that was left was the metal casing for the seal. That's all that was left. I also pulled it and resealed everything. So far.. no drips.. I hope it stays that way too..

Good deal. Glad to hear it's fixed. Sorry I couldn't swing by. My 89 is still throwing a code.

I know this is old and I revived it, but this is the closest topic I could find to my question.

I am assuming that you do not need to pack the diff bearings, however my neighbor with his STi says that they are supposed to be packed and then put in gear oil...sounds weird to me though. Do you need to do both or just put it together and put gear oil in it only? I searched, but nothing answered my question so thanks in advance for any help.
