Hydraulic Clutch Thrust bearing options

[ivan129]

Looking for some options for a hydraulic thrust bearing to fit a W58 gearbox adapted to a 1UZ?

Does any one have a list of bearings that will fit and suppliers they can be purchased from. Also will the bearing assy require modifications to fit the front of the box. Thanks

when i did my R154 swap i used a HOWE bearing, so far so good, some people say theres issues with the howe, so quartermaster is another option. but realistically you can make any bearing work as long as the ID of the bearing will fit over the OD of the trans input shaft, you will have to shim it properly anyway with whatever option you choose. good luck with your swap! try the 04+ LS1 hydraulic throw out, its cheap! and its LS1 durable.

The howe/quartermaster units works ok with r154 swaps, it's mostly a w series issue. So for this application I highly reccomend using the t56 bearing which requires you to cut the sleeve.

Would you happen to have a part number of the Howe / Quartermaster unit to use with the R154?

The Howe unit part number is 82870 and can be bought from Summit racing in the US. A replacement bearing is recommended, part number NSK 45TKD-07, as the Howe bearing has a flat face. To mount the Howe unit in the right place either additional shims are needed or make a solid spacer with only a couple of the shims. This unit works well with a 5/8 master cylinder. I'm using a heavy duty single plate clutch from a Celica 3SGTE.

Thanks much!

Hi-jacking thread,
I am doing a Howe hydraulic release, and have a question. The instructions say to position in the 7'oclock position.

The master is on the other side, I want to position like so

Will it still work?

The unit you have pictured is slightly different to mine but the location of the hydraulic connections are the important bits. They should be up top, with the higher connection being to the master cylinder and the lower connection being the bleeder. The locator is only to stop the unit from spinning and its position shouldn't matter.

The unit I have can't really go in the 7'oclock position, the input shaft housing bolt hole at that position will only just make contact with the Howe location tab, so I'm going to have to mount it differently anyway.
Anyone one else used this type of Howe before?

Non of the bolt will reach the tab. Weld a bit of rod to the head of the bolt that lines up so it makes contact.

The kit came with 2 different thread type extended rod top bolts.

So where do I mount the bleeder?
Where do you guys normally put them?
Just on a bracket low down or something?

 

[4U2QUIK]

you can just run a braided line with a bleeder right next to your clutch master, so you can just bleed the fluid right back into the resivoir.

That makes a lot of sense!
Sorry for the dumb questions, but I have never seen a hydraulic release set up before attempting this one.
Thanks for the direction.

The instructions don't say to point the hydraulic connections straight up?

Does it really matter which fitting into the bearing I use for the bleeder line?
ie top or bottom are they specific master and bleed, is that what your saying?

or is it just the best way to get rid of all air locks?

Assuming the clutch master is above, run the line into the highest connection point. The bleeder is connected below and either run back up to the master as suggested by 4U2QUICK or route it outside the bell housing to a lower point and bleeding will happen by gravity.

Because air rises you want the bleeder at the top, not the bottom.

Hence my question, I believe that the bleeder should be at the top, and if they're not master bleeder specific, that is the way it should go.

I went to shim the release bearing up just now, took the measurements and realized that there are not enough shims supplied, at that the location bolt will only just make contact, like 1-1.5mm of surface area contact....
So looks like I need to have a solid spacer machined up, and just like you said weld a piece of rod to a bolt for the locator,

 

[4U2QUIK]

you will need a spacer that's about an inch long.
