Re: Water pump query

Then again, they might have made the change to keep the troops happy :? I think that's highly likely. Most of these after-market improvements make little difference. Your reference to a double row of vane chambers - is that actually what the improved pumps have? 6 vanes arranged in two separate sta...

Re: Old misfire - again

Clifford, I've used Pertronix, which I believe is the same as what you're using, on a number of vehicles. I've always static timed them with a lamp as I would have done with a normal points set up with no difficulty. Tony. Yes, I'd have thought it ought to work. But the fact was the point at which ...

Re: Old misfire - again

I've fitted the Accuspark, and touch wood, that has cured the problem. it appeared that sometime in the past someone had fitted a rogue distributor. It had the correct number on the casing, but on comparison with the new one the contact base plate was clearly slightly too small. The gap around the e...

Re: Old misfire - again

Chris Witor lists only

RKC1814SH Distributor 2500TC & S = Lucas 41624 45D used. From MM20,001 SUHS6 carbs, 307621 cam, 1975 onward.


for the later 2500TC and S engine. Mine is MM 45,985.

I'm tempted by the complete Accuspark version they list as correct for that range.

Re: Old misfire - again

Having replaced the ignition switch, just in case, as I'd convinced myself that the voltage at the coil flickered if I wobbled the key, and postponed for the moment replacing the tank connection rubber section as too hard to get at on a freezing cold day, and in any case there's a full tank of petro...

Re: Just another Thrust Washer

The thrustwashers serve two purposes. One is to resist the thrust when the clutch is disengaged. The other is to locate the crank and limit its fore and aft drift. The crank can only move as far as the big and little ends allow - it surely is very important that crank movement never exceeds the con-...

Re: Old misfire - again

I've discovered, I think, how the D45 is constructed. There wasn't a screw, unlike other distributors, but a thin extension on the end of the spindle with a grove round it. The thing that looked like a metal collar is actually a very mangled bit of plastic, which seems just to be stuffed into the ho...

Re: Old misfire - again

The six-sided cam assembly moves up and down, but won't lift off the spindle. It is prevented by the collar, which rotates freely but is held somehow. I know there is intentionally a small sideways clearance between the rotor tip and the cap contacts, but the arc swept by the rotor only just reaches...

Re: Old misfire - again and again

Well, of course I spoke too soon. It's been running well, but suddenly today the old falter recurred. Once it gave the first tremor, it seemed all right for a mile or so, but then gradually it did it more, and I could sense that it was getting worse , but I got home without trouble. It pulled up the...
