| 06/12/04 Simple adapter to bolt the Rover V8 to the Renault UN1 Transaxle. First a bit of 3mm plate had a flywheel sized hole jig sawed out, then 4 big bolts were put into the UN1 bellhousing, and the plate welded to the bolts.
The bolt holes for the Rover were drilled oversize to allow fine adjustment and the bolts were fitted with large washers.
When the input shaft & crank were aligned the bolts were tightened fully, and the washers welded in place to 'set' the locations.
All bolted together and dangling.
At present the block and box are a bit too close, but it will be easy to space the box off enough for the right clutch clearance.
xx/01/06 With a basic method of connecting the V8 & gearbox in place, the rough dimensions of the flywheel and clutch were guessed, leading to the following creation :-) It's a Land Rover flywheel, chamfered so as not to foul the UN1 bell housing, and redrilled to suit the clutch from a Puegeot diesel that happened to have the same splines as the Renault box (406 TD 2.1).
The new release bearing is a tad too wide for the fork, so the old Renault bearing is going back in.
12/03/06 To get a good shaft engagement into the clutch (ooo er!!), the box actually needs to move closer to the engine, so some material needs to be removed from the front of the bellhousing. Good job I had 90 minutes spare and a few spare hacksaw blades.
(Don't worry, I used a 17mm open ended spanner as a depth gauge to scribe a 'cut here' line around the outside first ;-)
21/05/06 After a bit of fiddling (which loosely comprised of accidentally knocking the splined center out of the clutch plate -shouting "bugger" a lot - then welding it back in), the block and box slipped together fairly easily.
Splined bit looks fine welded back in, don't know what you're all worried about ;-)
How handy is that, 25mm box provides the perfect spacing - almost as if I had actually planned it ;-)
Shaft engagement (fnar fnar) looks really good and there's even space for the release bearing and fork. Yes I will be cleaning off the powdered aluminium from the earlier hacksawing.
The plate was clamped to a solid 1" thick slab of wood to stop it warping while welding the bits of box on. Tip - scorched cedar provides a pleasant scent for the shed.
With the box section 'spacer' bits in place the adapter was bolted onto the gearbox, then a band of 25x3mm steel strip was clamped, wrapped and welded around the edge. Hopefully this will help prevent flexing in the adapter.
A bit more of the steel strip on the front of the adapter to hold the lower flywheel cover thing that sits behind the sump.
Ha ha, it still slips past the flywheel and sits nice and flat on the block.
All bolted together nicely, and best of all, turning the crank makes the output shafts go round :-)
With a bit of trimming , then a tickle with the grinder and cup brush, it should almost look passable !
