I think the ball on the very bottom of the stick should have this on it, which fits into the selector shaft.

I have just heard from Ashcroft Transmissions that the yoke is held to the selector shaft with a cotter pin which does not usualy give problems, so it looks like we'll have to look further down in the box, or just live with it.

Well firstly hello from Milton Keynes mate.
I'm gonna be having my box out to change the clutch and will buy a transmission cradle to do it. So if you need to borrow it, shout. V8 90...WIP |

Thanks for that, but it'll be the last resort to have the box out. I'm going to try all new std parts first and see how that goes.

Hopefully this reply is not too late, or may be of use to someone else. Yes, the yoke is held onto the shaft by a cotter pin, but it contrary to Ashcroft, it can and does come loose. You need to remove the transmission tunnel, gearstick and transfer stick, (unclip balljoint onto hi/lo selector) then unbolt the shifter unit (4x m8 bolts). This reveals the shift yoke which I expect you will then see is loose on the shaft. It is held by the cotter pin fastened by the m6 nut visible, which is probably loose. I slacken the nut off and drop a bit of loctite studluck on it, then retorque it up tight. As there is a bit of play in the positioning of the yoke I temporarily position the alloy shifter housing back onto the box and line up the yoke so it is visibly centralised in the hole of the housing, then carefully remove the housing and torque up the yoke cotterpin nut. Should only take an hour or so in situ. |

Spot on. Exactly as you described, took me about an hour and a half but I'm a bit of an old codger and half of that was getting the rubber mat out and the cover off. Many thanks.

Hi
I'm not very mechanically minded as I work in electronics I have a problem with my reversing light, I've checked everything out and worked out that it is whatever presses the ball bearing on the reversing light switch would i be able to access the actuator for the switch by the method shown in this discussion?? cheers Paul |

Hi Black wolf
Many thanks for the prompt reply to an old thread Any idea of how i can get to it?? I turned 1mm off the inside of the hex face of the switch to get it to go in a little further thinking this may cure it without any luck I've actually no idea of where the actuator is or how it works, i guess what ever the actuator is it must slide past the switch otherwise they wouldn't use a ball bearing cheers Paul Last edited by Paul Breen on 8th Apr 2022 8:36pm.

As I recall it is the reverse selector shaft which actuates the switch. Getting to it involves stripping the box completely.

OMG wasn't expecting that
I think I'll get the vernier calipers out and see if it's possible to take a bit more off the face of the reversing switch to get it to mate with ball bearing would you know if its a straight push onto the ball bearing or does it slide past ? cheers Paul Better a bad day on the water than a good day in the office |

Change the switch if you havenโt already, they can often fail. Unless you already have. No Guts, No Glory.

Hi Steve
many thanks for you assistance I've already tried this, without any luck. both the new one and the old are working fine. I read a post somewhere that the actuator was on the gear linkage and that the ball bearing wears a groove into a plate and that you can weld the groove in the plate and fettle it up, apparently the plate is worn down by the ball bearing as it's harder than the plate I cant find that post now though to copy and paste here cheers Paul Better a bad day on the water than a good day in the office |

Hi all
I found the post I mentioned previously, would this be a gear box out procedure ?? Cheers Paul "I had the same problem with my Disco. On the R380 gearbox the reverse light switch is activated by a steel block - this hasn't been case hardened sufficiently and a groove wears in it, caused by the reverse light switch plunger and consequently the plunger isn't depressed far enough for the switch to close the internal contacts. The only solution I could come up with was to remove the gear selectors and the block and run a weld where the worn groove was and then file it back. The weld is harder than the block and if you do this you wont have any more problems, the other solution I'd guess is to replace the block."
