aussie 4 speed hydraulic clutch.

hi can anyone tell me if there is a clutch slave cylinder for an aussie 4 speed box that i don't need to buy an adapter for? i have no slave cylinder or piping to one at the moment so i'd make one up but i can't seem to find one that bolts straight to the side of the bellhousing.
any help would be great,

I'm only guessing, but,
If someone manufactured a adaptor to do the job,
its because there wasn't one avaliable.

no worries, i was just wondering why there are the holes on the bellhousing to mount one, but no slave cylinder that atatches straight to it.

Hi,
the General made a hydraulic version available for left hand drive exports. I think they were from HQ onwards - but might have been back as far as HK - I dunno

It used the grey slave silinder but bolted on with a steel adapter - don't know about how the piping made its way across the firewall - but it was probably a different firewall to LHD models - I dunno. never seen one.

Rare's have the adapter - and may CRS also have them it uses the same Oz 4 or three speed sincro bellhousing. It just bolts into the holes which are already there.

You can use the existing piping down to the subframe anchor then fit a stainless braided flexible hose from there to the silinder - need to talk with Pirtek and get them to make one up with the needed connectors.

Hope this helps

Dee

Dellow Automotive were the first aftermarket manufacturer to make these brackets in the late 60's and still makes them today.

What motor are you putting the 4 speed behind?

The picture shows the cast bracket bolted to the side of the 4 speed bellhousing, the slave cylinder bolts to it.

thanks for the pic smooth, i'll give them a ring.
i'm putting it behind the hot 186 in my fb/ek thread.
P.S: i love your gear lever set up, custom built or bought?

Yep, that's the deal - won't find one any cleaner than Smooth Customs pic

One think I forgot - you might want to grind a bit away from the inner subframe leg where the hose is going to join at the slave silinder - I did mine as a prevention - it didn't wear through the rubber hose but took the paint off the subframe.

Still think the braided hose is the go - its thinner and can be turned around on a banjo bolt to point in any direction you want.

And another thing - you may want to pack the mount with a washer or two - I wore out my slave silinder because the alinement was out - it was pushing towards one side of the silinder and scored it - thats what the brake people told me when I asked about having it reslevved - cheaper to get a replacement from Bursons or Repco than have it lined with a stainless silinder.

By the way - when you come to speedo cable - get one longer than mine - I got one 60 inches and it is a real tight pull to get to couple up to the speedo in my dash. Probably another 6 inches woould be good.

The shifter was moved forward to clear the bench seat.

Dellows may be able to supply you with longer speedo cable
