[Idle adjustment knob]

Mine is just a solenoid on/off valve with 12mm pipe connections probably off ebay. I hid it inside an old coil with the internals removed.

"I was hoping to make it operate electrically, but couldn’t find a large enough solenoid valve suitable for low vacuum"

I did something similar using a washing machine water valve(12v) to control fast idle.

[Duff loudspeaker]

Checked the wires for shorts, all fine. One of the rear pair of speakers is 3.7 Ohms, the other 0 Ohms so definitely duff.

I've had loads of old bangers with a duff speaker, I'm just so surprised that one channel can cut the entire amplifier. Learn something everyday.

On the plus side the new head unit has bluetooth and in-built mic so the TR instantly has mobile phone connectivity.

Can anyone use a Blaupunkt Atlanta radio/CD player that probably has nothing wrong with it?

Jerry

[Duff loudspeaker]

The radio/cd in my 7 has had an intermittent fault where all the speakers stop working. The power to the unit is fine. It's got 4 speakers all separately wired so after checking all the connectors multiple times I came to the conclusion the radio must have an internal fault so swapped it out. But the same fault returned. After more checking, I found that one of the speakers wasn't working properly & disconnecting it appeared to make the fault go away.

So, (a) is it possible for a fault in one speaker to cause all the channels to go off?

(b) how do you test a speaker?

[Tr5 restoration after 17 yrs]

Why would a dealer keep a chassis on display unless it was a reject & the factory didn't want it back? Seems odd. Have you checked the suspension pick up points are in the right places!

As far as mods or originality are concerned, I'm firmly in the mods camp. You need to make it fit your needs and resolve any of the known issues.

See pinned topic in TR6 section, probably answer most of your questions.

Easy enough to modify something like these

[TR7 Cylinder Head Torque]

My BL TR7 manual quotes 50 lbft.

My BL Sprint manual quotes 55 ibft.

I have seen 58 & 60 quoted. The TR7 & Sprint manuals differ in tightening sequence, however I would suggest tighten incrementally from the middle working out starting with the nuts then bolts. eg: Nuts 20, bolts 20, then nuts 40, bolts 40 etc.

I use 60 lbft on my Sprint engine.

Run to operating temp & leave to cool. Re-torque.

Repeat after 1 hour at operating temp.

Repeat after 250 miles & 1000 miles, then every 3000 miles.

Minimal dust with Hawk HPS on my TR5. I'm not sure they are available to fit the Princess caliper.

[Oil pressure with a cooler]

Do you mean a second longer than normal or just a second?

Don't think I've ever had a Triumph that showed oil pressure within a second!

[Toby's new project]

You'll have to modify your nice lifting frame at the rear where it picks up on the seat belt mountings. They are in a different place on the 5 & 6.

Can anyone tell me how smooth and flat the floor needs to be for these tiles to fit properly,

My garage floor is not the best a bit uneven, I was thinking of using a paint on finish but you guy's have got me thinking.

Brian

Not perfect by any means. Mine was a bit scabby, filled in some of the deeper holes with a self levelling compound before laying the tiles.

[Preventative measures at the rear of the engine block/gearbox plate..]

Probably better off having gaps to allow any condensate to drain.

Jerry

[Chassis strengthening TR5]

I believe a couple of gussets are welded in here if you convert to damper in spring mod.

Don't believe it's a problem otherwise.

Jerry

[Air hose routing]

If you move the 'Y' connector from the fresh air duct to the demist duct, you are then able to get warm air to the eyeball vents to demist the side windows.

So much nicer to work on and keep the place a lot warmer.

[V8 distributor drive and oil pump]

I've been helping a fellow member with his TR7 V8 and as I know nothing of Rover V8 engines I have a few basic questions. Engine is 3.9

So, it turns out that the engine refused to run because the distributor drive gear which is located on the front of the camshaft had lost most of it's teeth. These are not broken off, but worn away. Curiously the dizzy drive gear looks almost untouched. How common is this, and why?

The oil supply to the gear appears to be along the camshaft nose through the keyway - is this normally sufficient?

The oil pump is part of the timing cover on this engine and is showing some wear - can this be recovered or is the entire very expensive timing cover scrap?

The timing chain is slack and there is no tensioner (by design - at least I think so!). Recommended suppliers and helpful suggestions please.

they've been breaking since the IRS system came into use.

That statement is neither quantifiable or can be proven. Triumph IRS is generally robust & long lived.

In recent years there have been rear hub failures, possibly due to hubs being rebuilt and the stresses put into the components on disassembly. Personally I wouldn't rebuild one

[Steering column top mount springy thing]

That makes sense Rob. Supports the column switch wiring harness. Seems a cumbersome way of doing it though, weren't cable ties invented when they were building 7's ?

I'll delete it without any qualms.

Jerry

[Steering column top mount springy thing]

Any idea what this is?

Sprung wire thing that is bolted beneath the upper steering column mount. Looks like it could stop the column dropping if both shear bolts dropped out, but it's far too light for any safety use surely. Unable to find in on-line parts manual but I don't really know what I'm looking for.

[TR6 rear lights]

Do the LED bulbs actually need a reflector?

The ones I've seen would appear to only face towards the lens.

Make an interesting experiment to compare without any reflector.

Isn't it time we stopped using fireworks anyway. Can't see that launching tons of pollutants into the atmosphere is a great idea. Wouldn't a laser display be just as effective?

No, not exactly local. Maybe you could try the Birmingham group?
