I was totally confused till I looked back at some old Pm's from harvey and yes I have the long cable which was superseded by the short one sorry for the incorrect info Warwick I will engage brain next time as yours is a 1970 Warwick and mine is a 69 was this the C/O period? while we are on the subject my box has a red label and it is a 6FU I cant find any info re a 6FU

My parts book says
long cable 605403 Cars up to suffix C
short cable 606514 ________Suffix D onwards.
Short cable 607927 ________303 transmission.
Transmissions;
1 FU Blue plate Body suffix A 5 FU Red plate "_____ " ___ B 267 French blue _____ check 303 Yellow _________ check

As I said - gear box numbers and 2 "short" cables but mods and productions difficulties can mean almost any combination
The 303 box represents the pinacle of the BW35 development fitted in a P5B so its the best one to have, it even has self adjusting brakebands and a pre-set inhibitor switch in theory

Trying to find out kickdown cable type and length by chassis number is a waste of time. The later (short) kickdown cable was fitted as a mod to early boxes, cars had later spec boxes fitted as replacements, and then you get boxes like JohnW's, where you haven't got a clue where it originates from! 6FU indeed!
Add to the list of transmissions 7FU with a green plate.
As Phil says the 303 is the ultimate Rover 35 box, but that only has a self adjusting front band, all rear bands are manually adjusted on the outside of the casing.

That is correct humphrey for my old girl but I wonder why mine is a 6FU at least I have harvey beat!

Might be from an Austin Cambridge , Humber Sceptre - a lot cars used these boxes and when they have been rebulit they can have different parts put in them anyway

I rang several well known gearbox specialists Phil and they could not find a reference to a 6FU so it was specialy made for my old girl a one off ;D

The general view from those in the know is that 6FU will be a Rover box, because of the "FU", but maybe an export model. As for what they (35 boxes) were fitted in, around the 1960's/70's it was pretty much everything, with variations in Rover Triumph Jag Taxis Morris (inc Landcrab) wedge princess Mazda Saab Rootes, Ford, and plenty more that slip my mind ATM. All basically the same, you just have to know which bits can be used with which. But the ones with letters in the series number usually relate to one type/make of car. Things get a bit more complicated when they move on to numbers only. Loads of fun.

harvey I like my idea better a rover one off box With all the faults ironed out Apparently you're correct, it's a one-off custom build by Borg Warner, they just wanted to prove that they could build one that didn't go wrong! Seems to be working so far!

You lot have been busy while I've been sleeping. Well I pulled the air-cleaner off and this is what I found. Sorry about the poor focus. Looks like this whole area could do with some attention. A good clean and new hoses and clips for a start. (The in-line fuel filter at the top is in the rubber breather hose from the back of the engine to the air-cleaner. The extra throttle cable with the ball-chain end is for the cruise-control, as is the 1/4" rubber vacuum line across the rocker cover at the bottom of the photos.) The plastic bushes are worn, but not excessively so. I would describe the shaft as being a rattle fit. But it doesn't bind. At what level of wear does it become a problem? The BW35 is pretty common here too. The Ford Falcon used a version for years behind their bulletproof 4.1-litre six. I wonder how much they differ? I'll ask at my next club meeting? If mine is original, and it was built in March 1970, how many versions came after that before the end in 1973?

Nice clear pictures Warwick I see how it works and how mine was modified for the SHORT cable where your Cruze Controll fits is where my kick down is and where your kick down shaft is I have an extra litlle lever with a return spring "I see the light" at least you knowhow it pulls now as to how much wear in the plastic bush I would have thought a little would make no difference as long as it hasn't collapsed "Quite right" harvey "quite right"

John, do you mean that yours has the same castings on the inlet manifold that carry the bushes and shaft but its original purpose was for the throttle return spring?
At least I understand how it works now. The next thing to figure out is what's wrong with my manual cold start system. Something odd happens on the RH SU and the action that should lower the jet seems to get lost by rotating.
I think I will also remove the aluminium tube manifold for the rear heater and connect directly to the main heater. It gets rid of some clutter and potential leakage points and the rear heater isn't needed here. Not cold enough. The hoses under the floor at the rear are leaking too.

Yes they look the same Warwick where the shaft joins I suppose that has a roll pin or something that fits the slot on the kick down shaft mine has a small lever where a spring is attached the spring goes to another bracket on the water inlet which is not there on yours the shaft is not there on mine I must admit the one I have is easier to get at to adjust

If you have the right bracketry either sort can be fitted as all manifolds has the holes and castings for the long type linkage for teh short cable

Is the nut and bolt through the clevis on the end of the kickdown cable an Australian factory modification?
The throttle bush actually makes a vast amount of difference because they tend not to wear but break up and fall out altogether, and once it's gone you're unlikely to be able to get enough travel on the cable to get it to kickdown.
They aren't that difficult to get to and adjust.

If the bush is worn and slightly slack as long as the gearbox changes at the richt speeds throughtout the throttle range its oK.
Kickdown is bad word for theis cable as it does work at other throttle openings as well and is often the cause of gear change problems.
The single carb bracket for the long cable on earlier versions was much less trouiblesome but apparently not precise enough - the plastic bush wearing on the "improved" later versions soon removes any precision. A brass or sintered bush would have been far better but BLMC cost cutting was at its height.
Late 72 and 73 cars will have the best gearboxes. The main differences to boxes fitted to other cars apart from the bellhousing were the tail shafts and valve bodies, teh rest of the internals should be the same

The main differences to boxes fitted to other cars apart from the bellhousing were the tail shafts and valve bodies, teh rest of the internals should be the same On other makes bellhousings and tailshafts differ as you say, but so do the main casings, and so interchanging between makes is not as easy as it may seem. Even if it's just the tailshaft, that requires a gearbox strip out to change. On (V8) Rovers all the tailshafts are the same as far as I know, and it's only the lower part of the valve block that differs, it's slimmer to allow use of the snorkel filter. It's true that otherwise internally they're pretty much the same but not everything is identical, although with the right compatable parts they are interchangable.

The cams are only fitted to the valve block with 2 screws IIRC....

The cams were the same on the all one I have seem

Post by harvey on Oct 14, 2007 16:30:16 GMT
The cams are the same, the reason there are different part numbers is that the cam only comes as an assembly with its mounting, and the mounting for the 303 box is cranked to keep the cam in the same place because the valve block is higher relative to the sump so there is enogh room for the snorkel type filter.
The short cable was a factory modification that could be fitted to any gearbox, supplied with the long cable.
