3/8 UNF, male fittings have single flare female fittings double flare. Laurence

Don't worry you can still do doughnuts with it, as I can testify. Laurence

NASTY ! Sorry to see that. Laurence

Job for the plasma cutter. Still think setting the gearbox up in the lathe and grinding it with a grinder in the tool post. Laurence

For performance the 1300 manifold does not even compare to the twin pipe, even on a 1300. I CAN TELL YOU THAT ! Laurence

Front cross member, hinge boxes, outriggers frame over diff, steering rack mount and short outriggers. Also trimmed down short outriggers trimmed off top of rotoflex brackets and underside part of inner turret mounts. Note most holes dimple died too. Laurence

Sound idea Nick I have plenty of Big T back plates kicking about, The plasma cutter would make very short work of one. but trying to reduce weight not add to it No panic anyway ! Car needs body tub and a chassis (Yeah she is that knackered). building as a road legal race car from the ground up. Currently punching holes in a reconned chassis taking a pound or three off it. Replacement body tub also altered a bit. Laurence

A COMPLICATION ! Today I put a Gt6 flywheel. Also brand new 2300 / 2600 / TR7 clutch on a mock up engine for measuring up distances for the concentric clutch cylinder. The good news is, as I expected I still have to machine back the aluminium hub that carries the cylinder a bit more. Even had I machined it back too far I can always shim it forward again. ANYWAY I don't need to do that ! HOWEVER ! The complication is that the spigot shaft is too long. The mounting flat on the flywheel is 158mm away from the face of the gearbox. The end of the spigot splines to the gearbox face is 162mm so spigot is 4mm too long. I can resolve this. Just have not decided exactly I will do this. Any Ideas welcome. Drill and grinder or set the gearbox up in the lathe and mount a grinder on it ? Laurence

Vertical links are DROP FORGED STEEL not cast ! Will weld no problem at all. Laurence

The Rover 2300 / 2600 bell housing bolt holes all bar one line up (Big T / TR TOTALLY STOCK engine backplate ) perfectly bar one bolt, this is where the protrusion for the clutch arm sits. The said protrusion had to be cut off to clear the chassis rails on Gt6. Hence the need for the concentric clutch slave cylinder. Laurence
-
Yes Nick once I got my head around mounting the cylinder and securing the hub. Still a bit of measuring and a little machining to do. But getting there. Laurence
-
The Mondeo concentric clutch slave cylinder conversion MOCK UP. Laurence
-
I am attaching photos of the LI77 Gt6 gearbox conversion the first photo is relevant to Big T the others attached for pure interest. Laurence
-
Sorry this is the mock up of the concentric cylinder and its hub. Laurence
-
Update with pics hopefully ! Pics show modified 2300 / 2600 Rover bell housing to the Triumph six cylinder. Modification to Bell housing and the piece cut out. Also MOCK UP of the concentric clutch cylinder its mounting hub. As stated this is a mock up I still need to measure up distances to clutch diaphragm and machine the hub to suit. BTW the spouting bolts are all local hardware shop had WILL BE CHANGED ! Laurence
-
Jonny Jimbo is absolutely right NEVER ADJUST THAT ALLEN SCREW ! Slacken the two quarter bolts each side of it. Laurence
-
On my sixes I drill down a little into the head and the block and cut a small sleeve tube (Dowel) If memory right 5/16 then a small amount of Hylomar on both sides round it the head is then set on. Laurence

I too used the big Citroen discs with stock Gt6 callipers widened. Under 15 in wheels. Scrub an awful lot of speed very quickly. Laurence

I was asking the guy who bought the V8 engine and bell housing (V8 Rover specialist) his opinion on the LT77 box. His reply was that the LT77's poor reputation is mostly undeserved. He maintains a lot of this poor reputation comes from guys with kit cars building high HP Rover engines and fitting them to untouched boxes with 100,000 miles on them and thrashing the nuts off them they then suddenly explode. He said if properly rebuilt and serviced it is a perfectly good box. Laurence

LDV Pilot. Laurence

I have found a contact who reportedly has a load of these bell housings (Ballymena Northern Ireand). I sold the V8 and bell housing into the trade. The guy who bought these specialises in reconning Rover V8s. He maintains he has previously weighed these 2300 / 2600 in but he will not be doing that again now he knows what they fit. He also has a load of LDV Pilot short remotes. If any interest PM me I will forward contact info Laurence

While hunting one I was told of a 2600 engine and box locally also found a bell housing in Detroit, and yes the R380 will also fit. Unfortunately I do not have an R380 It is a C suffix LT77. And BTW they are the weight of a small mountain. And yes a LDV Pilot remote will do it but not hard to shorten the SD1 unit. Laurence

IT FITS !!!! It is official a 2300 / 2600 Rover LT77 bell housing bolts straight up to a big T or TR engine backplate LESS ONE BOLT the one just below the starter motor this is where the slave cylinder should sit on the LT77. This area I will be cutting away, firstly because it will foul my modified phoenix exhaust manifold secondly because this protrusion will also foul the chassis further back. I will be fitting a concentric internal slave. One thing I did notice the gearbox will have a cant towards the left on a vertical mounted engine. So in other words fitted in a big T gearbox will be vertical. Another point is that longer bolts than Triumph used will be needed also longer the three top studs. Not a big issue. Next is an appointment with the plasma cutter and find a suitable concentric slave. Also had a look at the gear lever remote in regard to shortening it. THIS LOOKS STRAIGHTFORWARD. Laurence

Will find out tomorrow Nick (Monday 21st) going out to workshop visiting rights on my projects. Laurence
