Philip's thread of 660XYB stuff

The bottom ‘box is the Ford Type F 4-speed as fitted to the Sabre Six. Overdrive was an optional extra. The same basic ‘box was fitted to late SE5a, and all SE6 with the J type OD.

I’ve always thought that a well engineered linkage like those (but lower profile) would sell well in the GTE/GTC world as it transforms the gearchange.

Chris, out of interest, what rpm are you doing at 60 mph with OD engaged?
Fairly modest revs Philip - I'd have to check to be sure. I calibrated my rev counter when I swapped from positive to negative earth so I know that's accurate, but the speedo over-reads a bit. I'm currently shod with tall 165/80 15-inch tyres, standard 3.58:1 7HA rear axle.

I'd guess at maybe 2,500rpm at 60mph with the o/d in? Will confirm - an excuse to get the car out and rag it up the road!

Thanks Chris;
My (other) "problem" is the diff, set up for hillclimbs, is 4.1:1 which is why I don't do 70 on the Motorways, unless pressed.
I'm assuming the one I have on order from the Netherlands will be closer to standard - I'll just have to live without LSD.
the OD just needs packing up and sending off; I have instructions for DIY refurbing but I'll leave it to the experts.

Been out for a short run today. Using the sat nav for accurate speed, I measured as best as I could tell 2350rpm @ 60mph o/d in, 2950rpm 60mph o/d out. At 75mph with o/d in it was 2950rpm.

Chris,
Thanks for running a test on your private estate roads and letting me know the result. 8)
I'll update the thread when I get the OD back.

If you are like me you've been reading every new post you'll have seen I've got the OD back from Overdrive Spares. Being a transmission novice I had to ask David Twigger a few questions before I could get it back in.
Here's a picture of it as I took it out - the back of the engine is jacked up and you need 7" clearance for the OD to slide back:

To get the splines aligned you need to free-up the cone clutch; it's not under load (no springs fitted at this time) so I put two tyre levers in, one under each piston, and then rotated the body until the clutch and drive splines were aligned; I then used some 2" masking tape to tape the flange to the body to stop any further rotation.

It was also important to align the splines with the gearbox shaft which was locked by putting it in gear with the eccentric pump cam in its lowest position. Then, as the OD came close to the gearbox I could slide the eccentric cam under the pump, wiggle the OD so the cam went onto its splines and simply bolt the thing up. Took me three days to get everything right !!

Job done; topped up with oil and taken for a test drive before replacing the tunnel. Engagement is a bit harsh so I'll be using the clutch to begin with, but I'm advised the new cone clutch will bed in after a few miles.

Here's a simple question but it might have a complicated answer....
The straight six rocker cover is held down onto the Mays Head with 7 pan head setscrews; these are 1/4" x 20 tpi, length 5/8"
So, are these UNC or Whitworth?
I have the official Ford Spare Parts List (unfortunately it's the 1956 edition for the Mk 2 206E engine, not the 213E but they have the same fitting), and it lists them as 1/4" x 20 tpi so my measurements confirm this. Nowhere does it tell me what standard thread form is used, and I don't have a proper set of thread gauges.
60 degree or 55 degree? :?: :?

Hi Phil
1/4" X 20tpi of that era would be UNC.
The rocker covers on the V6 Essex are UNC too.
Whitworth was very rarely used on any engines, particularly Ford.

OK it`s a May`s head, but I would not have thought they would have moved away from the norm.

On the Ford Straight 6 head I have they are deffo UNC.

Thanks Mark,
That's just what I needed to know.
Going back to the list of goodies that you are (still I hope) holding for me, could you pm me the final cost and your address details and I'll send you a cheque.
Discs and pads, rear shoes, ss plates etc,
Then let me know, and I'll arrange for my brother to call over to collect.
Cheers,
Philip
