Finally changed the left hand engine mount this evening, which was looking very slanted- followed Phils approach to putting in dowels (Char Lottie / Margrae blog, cant remember which!) to the new mounting, but threaded to M6 , popped in a couple of bolts and ground off the heads. Bingo. Went for a drive. BLIMEY!!! Wish I had done it ages ago!
The right hand one will get done, but Ive had to leave the mounting bolts soaking with penetrating oil. I think Ive just found the only oil-free bit under a CF bonnet!

Regarding the timing belt cover, the mould is ready.. It definitely doesnt fit in our vac forming machine, but I have a cunning plan...
Not knowing how thick the material will end up across the forming, Im going to try something I dreamt of which might just work:
Im going to make a box a few inches bigger than the mould, but smaller than the sheet ABS Im going to use.
Place mould on a big plastic sheet.
Heat ABS
Drape over mould , Place said box on top.
Immediately chuck on as much sand as I can to force the ABS onto the surface of the former.
Allow to cool.
Im going to put air escape grooves on the underside of the mould and use thin tube to allow air to reach the outside of the box.

Its a crazy plan, but with a bit of luck might just work!

Only problem is, bit broke so might have to wait to order ABS!

Busy day!
Replaced alternator brushes (nabbed from an alternator off ebay- corrct model n all, but the shaft was too short to get the fan and pulley on, so will buy new brushes and reinstate ebay alternator and sell on).

Replaced worn out leisure battery with a normal battery as a temporay measure.

Replaced front shocks, though had to get a nutsplitter to get old ones off.

Rather pleased with self. Must treat same to a beer.

Tomorrow my overdrive box will arrive so bedtime reading is going to be the relevant sections in the Haynes manual. I'll be cross referencing with the search facility here too.

Ill keep taking pics for this one- not just for others reference but also so if I go wrong somewhere, someone might spot it!

Hopefully my ABS will arrive this week to make the timing belt cover.. dont worry, I hadnt forgotten!

I had the same problem with a new alternate that I bought off ebay. If I put the fan on it fouled the alternator body, if I packed it with a washer, I couldn’t get the nut on. In the end I carefully filed about a millimetre off each of the fan blades, I don’t know if the alternators are poorly made… or do they need a different size fan?

Looks like you have got it sorted now

Perhaps its a variation in the model- Ill jot the numbers down to see how they compare and perhaps you could see if theres any similarities with your experiences.

The alternator fan seems a simple affair- and judging by the shape of the one on the alternator when I got the van, it seems that witchcraft, not science, dictates effectiveness. I daresay a bit of filing wouldnt harm!

EDIT- the one that is too short had 0125 46 2 45A on the side.
The one that fits had (to be added) on the side.

Overdrive box arrived today, though havent had time to do anything to it yet because I had my youngest over today and had to do some crazy dancing to Mumford and Sons (and a bit of Donna Summer, T Rex and many many others). Makes yesterday seem like a walk in the park!

First thing Im going to do is separate the gearbox from the overdrive unit. And look.

NOw, I know Im going to need a shorter propshaft- theres one on ebay Ive asked for dimensions for, at the least I can get it cut down to the correct length?

This is the first time Ive been seriously full of trepidation- theres lots of bits in a gearbox and overdrive, Ive never done it and im like a jellyfish juggler with amnesia going for a world record. This could be fun. Then again...

Cleaned up said overdrive/gearbox and have undone the bolts- can separate the adaptor from the casing by about 7mm but no further. Dont want to force it- am I missing something or will it just go?

If you're trying to separate the extension adaptor held to the casing by 5 bolts then put the bolts back in: adaptor comes off with the mainshaft & gears after the selector cross shaft, striking forks, selector forks, rods and countershaft are removed.

Overdrive should be separated from the extension adaptor first.

I was exaggerating. About 3mm, not 7. Typical bloke.

Im suspecting the overdrive is in the on position, though I bench tested the solenoid and it gave a satisfying clunk each time I made or broke contact.

Still bemused as to what I can do. wondering if theres a way I can see if its engaged or not.

The gearbox was in neutral when I tried to separate them, thats why I suspect the overdrive.

Left it on the bench and took out the roof lining to get at the seam between the fibreglass halves, but need to take the over cab luggage surround down to get at the main leak (the ply behind it had delaminated, and theres an occasional drip from there).

Got too dark, so had to leave things there.

EDIT: Phil, you must have been typing whilst I was. Did think about taking adaptor off first, but the Haynes book has obviously mislead me.

Just to get this right- remove overdrive from adaptor first?

Dat de one

If the overdrive won't budge then the mainshaft may locked up by opposing forces from the one-way clutch and sliding clutch (the cone bit) with the overdrive not being disengaged with the clutch depressed before the gearbox was removed.

The way to unlock the shaft is to pressurise the overdrive via the adaptor plug hole below the solenoid & switch the overdrive on then off. A grease gun filled with oil should generate enough pressure; big grease gun should do it in one fill.

Don't be too hasty getting rid of the VX4/90 box - you need the mainshaft to go with overdrive & could end up using all the VX4/90 gear train if it's in better condition than the CF bits (& the main drive pinion is the same number of teeth).

Thanks again- Im trying to work out the opportune moment to take the gearbox off the CF, but I need to find a pocket money banger before I can!

More work on my leaky roof seam this evening- masked off and put some resin down on the outside too to sand down later . New batten up over the luggage area so now ready to insulate roof and get ready to order new board. No pics cos phone got a soaking!

Right- getting slowly back to things after a close encounter between my thumb and a bandsaw at work (distracted by boy asking questions.) Been getting through alot of superglue, but its holding enough now to get back to work and my phone has been repaired and sent back so I can start taking piccys again.

Ive managed to get a few jobs done too- having taken out the overhead kitchen cupboards, Ive ordered the foam to insulate. Just need to remove the old 3mm foam so I can glue the new stuff in place.

Im also making progress with the timing belt cover- though Ive had to start making up a clamping box big enough to cope, which I shall be powering off the machine at school. I should also have enough space under the heater to fit the required sheet, so Im keeping my fingers crossed... the ones that dont have saw marks in.

Havent got the overdrive off yet- a bit too messy wearing bandages and dressings, but will be on the case soon.

Right finally got the overdrive off the extension adaptor, before realising that I dont have a clue how the existing gearbox on the adaptor is assembled. Been trying to picture it together from looking at the Haynes Manual and guesswork but Ive lost the bottle.

Identification markings on the gearbox are:

Underside: 7198327
Drivers side: 17F7
7211158 (by selector)

Found this which might help:

Im wondering how useful the Haynes guide will be to a gearbox novice like me.

Heres a pic of the box:

Any ideas?:#

Casing opened,

Drive out the circled spring roll things next?

No. Remove countershaft gear next after unbolting extension housing & rotating it for access to the rear of the countershaft that then can be driven out from rear to front. Countershaft gear must be withdrawn with care so that the needle rollers don't fall out.

Then remove the reverse stop housing after which the spring pins are driven through only as far as necessary to release the striking levers. Do 3/4 lever first (top of your photo) then 1/2/R lever before allowing shaft to move out of either side of the casing.

Check your pmail.

A timely stop then!
Im going to take my time- the next job is to learn the names of all the bits so I dont get so confused. Could you possibly label the parts on the photo because Im trying to cross reference to the manuals and not finding what you are referring to!
Itls like a giant, dirty 3D jigsaw!
The only thing Im worrying about is specialist tools- knowing my toolbox, should I be panicking yet?
