    Roverdrive LT95 epicyclic O/D soon.

    I have just had an email reply from the Roverdrive Corp about overdrives for the Series F/C and 1 Ton transfer boxes. In that email they suggested they are in the preproduction of a Roverdrive epicyclic overdrive for the LT95 box.

    The Roverdrive for the series box is significantly stronger and quieter than either the Toro or Fairey overdrives so I would assume it will be for the LT95 as well. I guess it is a case of watch this space.

    They also said that if we could find a group of 50 people they may even make overdrives for the 1 Ton or Series f/c boxes.

    Excuse my ignorance - is an epicyclic overdrive where the drive does not go through the O/D when it is not engaged?
    Definitely a short coming of the Fairey unit.

    Did they mention any ball park $$ should they go ahead with 50 units?

    an epicyclic gearset is also known as a planetary gearset like the ones found in autos..

    As Dave says, the gearset that makes the Roverdrive work is epicyclic (planetary gears) not like the Fairey and Toro units that have a mainshaft and layshaft arrangement. In fact the Fairey overdrive for the Series LR, had parts that came out of a Rover P6 TC2000 car.

    The epicyclic gears in the Roverdrive actually come out of auto transmissions that are designed to sit behind big US V8's so can deal with the weight issues of the Land Rover (Range Rover), they are also very much quieter.

    The drive that you suggest as being epicyclic is actually called concentric drive I believe and is a function of all the overdrive units.

    The LT95 Roverdrive is going ahead in any case, as they can be used in 101s and also Defenders with Isuzu 4BD1 so they see a market. The 50 units is only for the Series SIIB and SIIA Forward control and 1 Ton gearboxes.

    Very interesting, these are the same as used in reduction gearboxes on electronic motor gearboxes, I have worked on several layers of these gears used in reduction gearbox but on a much smaller scale.

    Lets get an approximate price.

    There should be some word on the LT95 Roverdrive by January along with pricing.

    One is to be fitted to "Matilda" the 4BD1 Isuzu 110 (below) for promotional activities in the UK around April.

    Definately keen to know more. A quiet reliable overdrive is the only thing I'm missing on the 120. I suspect the decision to get one or not will come down to pricing.

    Cheers

    The Roverdrive has always been an expensive item when compared to the Fairey/Toro alternatives but I have always heard good things about them and personally never heard of one fail. That has to be worth a few extra dollars.
