S1 rebuild....not one for the purist

The existing plates under each pair of screw heads rather puzzle me. They are too thick to be used as tabs. There doesnt appear to be a need for load spreaders and they do not tie pairs of bolts together in any way. They are harder than the CV body so they might prevent the screw heads digging in?

The linkage looks like it would be fairly easy to extend but I presume the remote couldnt readily be chassis/body mounted instead? Mounted properly the torque reaction angular displacement of the engine is quite limited. Common these days to mount the remote to the body but modern linkages are often quite long.
A majority of cars these days are Front wheel drive so the gear linkage is a remote box with a pair of push/pull cables. I looked at a polo/audi a3 remote as it has the same reverse position as the t9, but the cables are not flexible enough to bend back to the selector position and the mount was massive, size 12 shoebox size! so no way to get it in. (and i had to put it back in my partners car before she came back from her holiday) Alan 1209 said:
The sierra workshop manual refers to the plates as locking plates, I guess they work like washers to prevent the heads pulling into the gaiter flange and relaxing the "stretch" on the bolt, but being linked they can't rotate so help to retain the bolt. I have seen it suggested that you use Loctite 242 on these bolts. The judicious application of heat will release it, but using quality bolts in the first place is the way to go, Iv'e used Unbrako.
That is what they are, a hard surface to bolt up to, some cv boots will not let the plates fit or sit down tight, so get the right boots or trim down the plates. Loctite 242 is right for the bolts, don't think you will get the c/v's hot enough to release it, it has a service temp up to 149c.Alan

That all makes sense to me. I have also used Unbrako and Loctite. I did have one inner CV come loose in 2015..thank goodness just as I came through the gate at the 2015 Burghley meet!Alan
I am liking, and finding very interesting, the engineering approach!
(I have had a fair bit of stick in the past
for questioning whether some of the mods made or suggested, especially to matters where stress and safety have been involved, have not been thought through)greymrj said:

Not seeking to blow my own trumpet but this is one of the machines I designed, it processes rollers 7mtrs long, 800mm dia and 3 tonnes + rotating at 1200 rpm. You don't want that coming out.I am liking, and finding very interesting, the engineering approach!

Agreed with Alan above, no problem in blowing your own trumpet if you really know the music! But call that a machine 
, a mere bagatelle! Mind you it is a hell of a long time since I worked for the English Electric on power station design! 
A bloody good apprenticeship with them though in those days.

Just been looking at the RX8 box, the RX motor is a high reving engine but with low torque, how will the gearbox cope with the extra torque from the v6.
Alan
Depends on whether your looking at rotor speed or output shaft speed, which is 1/3 of the rotor speed and 3 times the torque. the peak torque is 220 Nm at 5000 rpm, way higher than the V6 with 168 at 2500. This gearbox is used on the 4 ltr ford ranger in the US and a number of other vehicles including the Lexus IS 200 with 195 Nm, and I know its used in a fair number of racing sierras.Alan

Yes, but without that machine you wouldn't have vinyl flooring for your bathroom, and without its little brother you wouldn't have plastic £5 notes, both so much more important than electricity, and to top it of nor would you have snickers wrappers......., a mere bagatelle!

Back to the TVR boy and girls. Have you had to cut the chassis to fit the gearbox. Nice to see someone else with proper tools (mill), You don't have a lot of room where the body fits down on the bottom rails, pictures please.
Alan
Just a slight mod to the 2 uprights, main rails are intact. Alan
replaced with
the new uprights are 50 x 25 x 2.5 RHS.
this increases the available space by 26mm, I have also moved the engine forward 10mm. but given that the new g'box is heavier the impact on front/rear balance is insignificant ( far less than the contents of the fuel tank)

Whats wrong with Steambut without electricity you wouldn't have your machine.....
