TR2/3/3A HELP! Clutch slave mounting orientation driving me up the wall.........

[karls59tr]

I have read all the posts about this and seem to be getting contradicting opinions? Is this the correct slave cylinder mounting for a TR6 transmission in a TR3A using a 3 finger clutch set up?? The slave "mounting bracket" goes on the BACK of the Bell housing........The flange of the slave cylinder is mounted on the REAR face of the "mounting bracket". Also does this set up,if correct, call for a shorter adjustment rod? Not so much being able to screw the rod in and out but in terms of a TR6 rod being the same size in actual length as the TR3 adjustment rod? Any help is greatly appreciated. Karl

Karl I have an early 6 box in my 3a I used have the early clutch but now use the diaphragm clutch
My slave bracket is fitted to the back of the gearbox flange and the slave is fitted to the front of the bracket and the rod is really short (sorry I don’t have the measurements. And the clevis fits to the middle hole of the lever

Thanks Is this photo of the set up with the diaphragm clutch or the 3 finger clutch?

 

[Hamish Racing]

It’s the same on mine

Thanks I'm going to send you a photo of the clutch slave setup that I just did that is the same as your photo. I have not attached the adjustment rod yet but it looks to me that it is going to be way too long? Any thoughts?

Here is a pic of how I was instructed ( by Randall Young) to set up the slave cylinder on a TR3A with early TR6 A type OD. And using a 3 fingered TR3/4 clutch.
And yes I had to shorten the rod a bunch.

That the same as mine
Just make sure the bleed nipple is at the top and the pipe on the bottom of the slave connections for easy bleeding

Thanks Charley This picture is how I will set up the slave mounting orientation. I guess I got confused by all the written instructions I read on all the forum posts....
Ie. the front of the back of the bracket......the back of the front of the bracket....the word flange used instead of bell housing and the bracket referred to as the flange etc etc. The post that said "on the engine side" and "on the differential side" made the most sense but the picture you sent made everything clear. Also thanks to Hamish for his input. Karl

It's interesting that Triumph used so many variations on the cylinder mounting...

Except that this is not stock. This is an adaptation of using different stock parts from different TR models. All in the attempt to duplicate the function required.

I am sure...but the engine block and tranny case were little changed over a decade and a half, although the cylinder mounting did. There were at least 3 adaptations that I know of...cylinder forward, cylinder back, with reinforcement rods, without rods, return spring tab relocations. Add to it owners cutting rods and linkages to make them fit and you end up with some strange arrangements. Throw in the broken fork pin issue, with the temporary fix of removing the return spring altogether...I can see why Karl is confused.

Charley Do you know why Randal said to "pound the ring gear inspection plate flat when you set up the orientation of the clutch slave " like in your picture when using a TR6 gearbox? I posted on the forum on Aug 2 titled ...In regard to this post RE: Will a TR6 transmission fit a TR3A? In that post I quote what Randal said about it. Karl

 

[charleyf]

Karl,
Best guess here.
The inspection plate has a raised edge that would interfer with the slave cylinder bracket laying flat aagainst the rear of the engine. . You want a flat surface to make sure the slave cylinder does not get a twisted orientation. It needs to face forward and back.

It appears to me that you are overthinkng to much of this. Let your common sense take over and keep you going forward.

However I do agree with you about the long verbal explanation about brackets and flanges and the order they are in. I had to ask Randall at least once for clarification and sat down and drew a picture of exactly what was being said.
