V6 essex timing gear

An aluminium gear has a better chance of bedding to an existing steel crank gear. I went this route, and the initial whine has gone after 5k. Slightly mismatched steel gears will not bed in any sensible time frame, so changing them as a new matched pair is probably the best way of obviating whine.

SE5a rebuild/rolling restoration - no brakes today

If the fluid remains on max, you don't have a leak. So either the master cylinder piston is not being pushed (pedal disconnected) or the piston seal is moving, but not sealing on the bore to allow pressure to be generated. Standard 5a is indeed single circuit.

Lockheed style servo modification

Orientation is solely to facilitate bleeding. The servo will work in any orientation, assuming you can bleed out the air.

IIRC, my 5a has an earth strap at a common connection for the dash earth leads, adjacent the heater valve.

Alloy Timing Wheel fitted

I fitted an alloy timing gear and matching steel crank gear 2000 miles ago. It whined to start with, not too unpleasantly, but is now quiet. An easy one man job to change both gears, and I changed the water pump at the same time

Brake fluid

If switching, or unsure, you will need to change all of the seals, including the servo cylinder (which does have fluid in it), and wash everything very thoroughly in brake cleaner or meths. The servo vacuum can should be ok.

Lockheed clutch master cylinder operation

There is nothing particularly odd in the two drillings through the wall of a Lockheed cylinder. The recuperation port should be open in the return position. Does it have a malfunctioning or mis-assembled check valve at the outlet? Common on brake master, but not so common on a clutch master. If the ...

Brake fluid

FWIW, in the 70's AP Lockheed did extensive texts on the merits of silicone brake fluid against the conventional stuff. There were sufficient disadvantages not to switch, and at that time it was definitely not recommended. But it works. Personally, I stick with conventional, but flush regularly to g...

SE5 clutch identification

Don't think I have ever seen a coil spring cover with a domed release bearing. The release arms are generally curved at the inner end to suit a flat roller or graphite release bearing. The pictures seem to show this arrangement.

Parts for sale

I was apprenticed there. The current brand owners are different businesses, though 'Borg and Beck' are a big motor factor now. No connection with Lockheed aircraft btw. Went past the old main site today; the last original building, where all the clutches were made, is being dismantled.

Lockheed was the brand name for AP brakes. Borg and Beck for AP clutches. However many parts had cross branding in the seventies, when 'AP Lockheed' had a very large motor factors range including water pumps, steering parts, wheel bearings, filters etc - in fact any fast moving consumable.

SE6A Overdrive

Overdrive is a 2 speed epicyclic gear. It cannot slip so the phenomenon you describe is not due to the o/d. There is a clutch to control operation of the second ratio, but if it slips the overdrive will simply stay in the first ratio. Perhaps the rev counter is at fault.

AFAIK, you need an mot for reg swop even if nominally mot exempt. Proves the car exists.

The second one looks similar at the front to a '54 Simca Aronde, but it's not. Possibly Soviet one-off?
