    Default SM - right hand drive - help !

    SM accelerator has gone limp.....

    no Viagra jokes please

    OK, so I have been somewhat slack. Or distracted. Maybe it was the DS23 headlights.... or the Light 15 brakes.... and so on.

    But i finally got around to dismantling the drivers side [off side] inner covers of the wheel arch and replacing the battery.

    wow that was fun, not!

    then, upon turning the car on.... hooray! it starts.

    But..........

    first time i pump the accelerator in about a year there was a "snap" sound and the pedal went floppy.

    the car is a rhd McLeod conversion [the very first one i believe]

    at the back of the accelerator there is a rod connected at right angles to a steel tube that seems to enclose a shaft and a right hand crank that disappears and must connect somehow through the firewall to the cable

    but it is impossible to see what is going on there. - it seems to be on the other side of the firewall

    if i push the accelerator all the way to the floor it transfers some movement to the cable, but for 90% of its travel it has no effect at all.

    does anyone know? can you save me a lot of time and effort before i dismantle everything?

    is there a spring? has it become dislodged? is there a broken part? the bell crank? a connector? a weld that has given up?

    From the engine side of the firewall, I cannot see down. The heater box [i think that is what it is] is in the way and it looks like it will be a ghastly business to dismantle and remove it so i do not want to unless it is 100% necessary.

    Any Frogger able to shed some light on this?

    and before anyone suggests i check the parts book or the manual IT IS A RIGHT HAND DRIVE car - it is not a standard mechanism and has been adapted for the steering conversion.

    and McLeod has closed down so i cannot ask him!

    in eager anticipation..... I await your collective suggestions or advice.

    if there is no other solution I will just have to bite the bullet and start undoing the heater machinery and swear a lot.

    cheers

    Perhaps one of the other RHD SM owners could jump in on this one.

    BTW - Pretty sure yours is not the first one. I think that honour belongs to Pajamas.

    Not sure about RHD, but the only way to see is to jack the front well up, put it on stands and get right underneath and look up. On the normal LHD the throttle cable is connected directly to the throttle pedal lever with a ball joint type end and the same to the bell crank near the carbs. Maybe that was replicated for RHD with a longer cable or an extra mechanical link between the pedal and the cable?
    Cheers, Marc.

    Jon,

    This picture might help. I saved this off the Peter McLeod website before it disappeared.

    If you take off the RHS wing, you will find the lever to cable connection and also get a really good view of the battery. I have more pics of the conversion process if you would like them.

    Cheers, Ken

    Ok so here is the problem.....

    the weld has given up...... the weld that connects the vertical shaft behind the pedal and connects it to the horizontal tube that goes off to the throttle cable has failed.

    photo available if anyone wants to see it but is too big a file to up load

    now I have to dismantle it all to re-do the weld.... grrrrrrr

    any advice welcome

    Cheers

    Could it be glued in situ with an epoxy adhesive? I'm not able to recommend a product, but this site is quite informative as to different types, strengths etc.

    Look on the bright side. At least you've found the issue and it sounds like you're capable of repairing it. Many of us have been caught by the "but I just had access to that before I put it all back together".
