pairing a Vanguard Engine to a Saloon box. pitfall

[Saltddirk]

hello,

As we found out the shaft diameter of the Big saloon OD box and the clutch on the Vanguard engine  (or TR 4 pot engine for this purpose) are of different diameters,

Easy enough to fit a saloon clutch/ release bearing/ pressure plate but are there any other pitfalls, point to look out for? The spigot looks shorter too?

Hi D

Here's memory for you. In 1983 my mate bought a maroon MKII 2000 with a damaged block and shot engine. We went to the local scrappy near RAF Cottesmore in Rutland and pulled out of the dirt a six pot which we thought was an early 2000 lump. We spent a good while cleaning it up and preparing only to find when we offered it up to the gearbox that it didn't fit. Obviously this is a while ago but I really think it was a bit more fundamental then just swapping out the clutch. I don't think the bolt holes lined up, or the input shaft is just too long or something, it was something major?

Anyway it was that much of a problem that we sold the engine to someone in the Vanguard club and found another engine.

You can fit a 2000 box to. TR6 by just swapping friction plate.

TR6 and 4 boxes are the same, so I assume it will work for you.

Clutch is lighter as well

Thanks Colin and Dazzer.

The box physically fits the engine, we have tried that.
I had my doubts as to the Shaft "design", ie the splines and spigot being of different length / Diameter

The engine is an early "vanguard" engine, 4 cylinder as used on the Renown. It is basically the same as TR2 but with different head and stud arrangement.
I dont have a TR crank to compare mine with, and am told that they are different but the bits sticking out are the same. (or at least seem to be)

Most of the Roadsters I know have, when they change for a TR engine kept the TR floor mounted 4 speed box. There must be a reason for that. Perhaps it is only because the gearing is now better suited for high way cruising (original box has only 3 speed), but maybe not.

I have a spare Renown engine and wanted to pair it to a OD box I bought at Stoneleigh. Pete has overhauled the box for me and it is brand new inside. That should give me a few more HP and a better gearing for the next RBRR!
