Transmission Sealant/Grease Question

[dongoesby]

I have read mixed reviews on where to put grease on the tranny as well as what type of sealant I should use on the front cover bolts.

Q1. As my sr20 swap moved on to the tranny. I've changed the front and rear seals, now when I remove this front cover (borrowed pic), fsm tells me to use "nissan sealant" on the threads of the bolts. I've found nothing about "nissan sealant". Can I use red RTV on these bolts?

Q2. My tranny has no rubber pieces/seals like the pic shown above. On mine, I could see the bearings (metal balls) behind these two seals (brown and black). However, I do have the metal o-ring that he is holding. Any idea? Is ok not to have those two rubber seals?

Q3. I'm sure that not to have grease on the surface of the throwout bearing where it has contact with the pressure plate. And I need to put grease on the pivot ball, release bearing holding spring. There are mixed reviews on putting grease on the pilot bushing and on the shaft teeth. Any truth on this?

Q4. Lastly, is this throwout bearing holding spring installed up-side-down?

Q1) Yes, you can use red RTV.

Q2) Yes, you need that seal from what I've seen taking the trans apart.

Q3) Any grease you put on the pilot bushing or on the mating surface of the throwout bearing will get heated up and cake off - the important parts to grease are the teeth and the input shaft where the throwout bearing carrier slides - that's what's crucial. Black molybdenum-disulfide ("black moly") grease is what you want, it has the best chance of standing up to that temperature.

Q4) Yes, the clip is upside down. You should be able to see wear grooves in the fork where the "crescents" on the prongs of the clip sit in the fork - it's not the most straightforward thing to install, but once it's on, you'll get it. The trick is doing all that once the fork's over the pivot ball :)

Thanks Jordan, you always provide me with good help :)

As for Q2, I've seen some trannys don't have those seals. Here is one: (this is how mine looks like too)

I'm not sure a seal could possibly fit in though. Maybe this is a sub-division of sr20 tranny?

And for Q3, it makes good sense that not to put any greast on pilot bushing and any where near throwout bearing mating surface. But if you put grease on the teeth, is there a chance that the grease would fly out all over the place? I'm thinking, as the shaft spins, the teeth section is exactly where the clutch disc is sitting at. Would such thing happens?

bump for answer.

If there is no seal, you don't need it. I've seen a few of each with KAs, but it's evident that if there's no place for it, you don't have one. Especially if the correct seal is fitted to the cover.

You're not applying that much grease. Cover the input shaft with a layer, that's it. The grease helps the shaft mate to the clutch disc as well as the pilot bushing, that's all. Once fitted it's tight and the grease doesn't have a lot of room to move around. Just make sure the throwout bearing and pressure plate fingers are dry.

thanks for the help again. :) but the whole input shaft with grease you mean? I'm guessing it would be something like this right? (maybe a little bit too much)

Bingo. That's maybe a hair much, but not a lot. I always grease it all up like that and have done several dozen clutch jobs without issue.
