[Gearbox with D type od - oil spec?]

In the W/shop manual, there’s a reference to a special oil for d type od and box. I certainly didn’t use anything special in a recon box way back in ‘89. Does anyone know of any such oil? I’ve bought standard mineral for mine.

Did you use the original footrest? I didn’t get one with my car. I was going to make one that mounts to the body, just to the right of the tunnel flange. 

[Gearbox tunnel - sealing, heat and noise insulation]

Sealing, heat and noise insulation on my GT6 gearbox tunnel. 

Plastic (vac formed, not injection moulded) tunnel from Rimmer Brothers. 

 

Lined, 100%, with 12 mm thick Pyrosorb-S is a class "0" accredited cellular acoustic foam. Safe and easy to install. Includes self-adhesive backing. 

 

Then skinned with Aluminised Heat Barrier

Flexible high temperature insulation. 

Woven glassfibre sheet laminated to heat reflective aluminium foil. Approx 1mm thick. 

Used Heat Resistant Adhesive from Woolies: Alphabond AF178 High heat resistant.

Rated up to 120 degrees centigrade. 

Ideal for vinyl roofs, headlinings and lining carpets. 

 

All gaps in the heat barrier are taped over with 3M 1436 Aluminium Foil Tape - 50mm x 50m.  Ref17:  MI-3M-1436-50 

Aluminium foil combined with high tack rubber adhesive and easy release liner. Holds and seals on a variety of surfaces. Offers excellent flame, moisture, weather and chemical resistance for a variety of demanding applications in aerospace, automotive, marine and many other segments.

All sorts. 

I’ll post it seperately as it rambles on a bit.

Thanks Paul & Doug.

Doug, I can’t find the thread. 

I’ve really gone to town on sound & heat insulation on mine. I used a different extrusion for sealing too. Do you want to see the spec?

My measurements for the centre of the plug are 6” from the bulkhead and 2” up from the surface that the tunnel sits on. This puts the centre of the hole on the angled face of the tunnel, at the rear of the starter motor. Is this similar to what you’ve found? 

[Gearbox Carbon Cover Wrap]

Indeed, a valuable addition. I’ll measure up for that tonight. I have to be careful when it comes to cutting it out though as I’ve used aluminium faced fibre glass material as the shield. An outside job, hopefully it’s not raining.

That looks fine Paul. Tucked away too so all ok. 

I’ve fitted a vac formed tunnel, in black, from Rimmer Bros and gone to town on it regarding sound and heat insulation, sealing to body and fastening to body. As I’m in engineering I’ve recorded all the details, as I do for all my enhancements, which I would post to benefit others.

Thanks Pete. I too couldn’t find anything, anywhere. I shall nip and Test.

Anyone know the torque for the d type overdrive filter cover fasteners? 

[GT6 mk 3 fuel filler drain & tank vent]

CC’s site does show a hose exiting through a grommet, it’s the same as the one for the wiper tube. I’ll get some 3/8” hose and send it through the boot floor, just to the rear of the inner arch, there’s a hole there. Does your vent exit close to the rear axle tunnel? 

[GT6 mk 3 fuel filler drain & tank vent]

Thanks Doug. It does show a tube (627454) which must be it as the other tube, higher up, has a end (rubber) to suit the push-on fitting. But, my filler housing casting doesn’t have a fitting, there’s little more than a boss 3/8” OD and 1/4” ID. The ID is smooth die cast finish, no thread. If the drain hose is pushed over the boss, ok, I can do that, I guess it exits through the boot floor via a grommet. As for the breather, I don’t have a facility on the tank! Is it part of the sender? 

[GT6 mk 3 fuel filler drain & tank vent]

Can anyone advise how the filler drain tube (9 o’clock in the picture) is connected (hole in lug only on my cap) and its route and, the route for the tank vent tube (3 o’clock in the picture) from its push-on fitting on the filler body-casting. 

Thanks.
