transmission fluid, flywheel bearing help

[DozerMagnus]

Hey guys and gals!

Can someone point me in the right direction as for a how-to on changing my transmission fluid? Transfer fluid?

I've got my tranny dropped now, changing the clutch. Its been fun. Not! But I'm learning, and haven't broken anything yet *fist pump*

Anyway, with a 1997 sr5 at 230k mi, I figure its time to change all my fluids.

Also, how the hell am I supposed to remove the bearing in the flywheel? I know theres a cheater way, to fill the bearing hole with grease, then stick a screw into it or something?... I have tried this, and the failed physics alone makes me feel like an idiot. OR maybe its not a feeling, but fact :help::thanks:

It's pretty simple, although it's much easier with the transmission on the vehicle (cold fluid doesn't like to drain out). You just open the drain plug at the bottom, drain out 3-4 quarts or however much comes out and then refill your fluid through the transmission dipstick tube in the engine bay until it shows the correct amount. Drive it around a bit and check the fluid. If still dark, do it a second time. Be sure not to overfill.

That's really it. Super easy, easier than doing your oil. I have no experience with the flywheel bearing though.

You can purchase a bearing puller. However you can easily, for this application, make one yourself with some odd bits of scrap metal. I'll see if I can find the one I made for this very job and post a photograph tomorrow. Meanwhile, here's a description and a crude drawing made in MS Paint.

Start with an 8mm bolt about 75mm long. (Or use a 5/16" bolt) Use a bench grinder and grind on its flats until you've made it so that the head can be inserted into the bearing's hole. Do most of the grinding on one side of the bolt's flats as you can. (gray in the my picture) You'll have to round the other side.

Take an 8" piece of 1/8" thick, 1/2" wide strap iron and bend it into an L shape. (red in my picture.) you may have to grind and shape the bent end a bit. The idea is that first you'll insert the bolt into the bearing, then this L-shaped piece will be inserted to lock the bolt's head in.

Finally, you'll need a short piece of 3" channel iron, blue in my picture. Drill an 8mm hole in it center.

Oh, you'll need an 8mm nut, too. (or 5/16")

In my experience pilot bearings are not a particularly tight fit in Toyota flywheels.

Once the bolt and strap are in place, put the channel iron over the bolt, put on a nut, and pull the bearing.

There are probably lots of substitutes for the channel iron. Once on a Tercel I used a very long piece of angle iron that went all the way to the edges of the flywheel. You just need something to pull against, and you need room under it to insert and hold the red piece.

Changing the fluids is easy, especially if you're doing your own clutch. You should see two 24mm thin hex's bolt heads on each case, On the trans it's on the left side and bottom and on the transfer they're both on the same face, rearward I belive.

Open the top/side plugs so you know you can fill if you drain, then open the drain plugs and drain out your old goop, reinstall the drain plugs with new aluminum crush washers, insert Redline MT90 GL4 into each case through the fill hole until it begins to dribble out the fill hole, install the fill plugs with new aluminium crush washers. Also now is a good time to install magnetic recessed hex (allen) drain and fill plugs if you choose. I have.

As for the bearing in the fly, I used damp newspaper wadded up and crammed into the whole then I drove a brass dowel the size of the pilot hole into it to compact the mash, added more when I could and eventually the hydraulic impaction pushed the bearing out. You can PB blaster the bearing to help, but make sure you get your fly good and dry with brake clean if you plan on reusing it.

Removing the pilot bearing is surprisingly easy. If you bought a new clutch it likely came with the centering tool which fits perfectly into the pilot bearing hole. So pack the hole full of grease, then start tapping the tool into the bearing and the hydraulic pressure from the grease will push it out. You'll have to top up the grease a few times, but it shouldnt take much tapping force.

Manuals have dipstick tubes?

Missed that

Thanks all for your responses! I got the clutch and valve covers done. Time to road test it.

I was considering Mobil 1 gear oil (https://amzn.com/B000ONZXPK) for the transmission AND differential fluid exchange. Any opinions on the matter?

Also, cannot for the life of me find the part no. for the transmission plug crush gaskets... anybody know it?

much love. e

I wish to amend the posting I made 2+ years ago WRT removing a pilot bearing. I can't recall how but I recently stumbled upon this YouTube video:

https://www.youtube.com/watch?v=00OlG5E8vLk

This past week I replaced the clutch on a '99 4Runner. I couldn't find the various bits I described in my earlier post, so I tried the method described in the video.

It worked like a charm. I suspect it only works on bearings that are shielded on the hidden side. That inner shield is destroyed by this process.

The compressed bread is indeed an easy clean up.

So, before you give up on replacing a pilot bearing - you baguette, so to speak - break out the bread. There's no - wait for it - knead to leave that old bearing in there. Don't be a gluten for punishment and use grease.
