    So what do you include when there is a Rolling Chassis? + Other Terms

    Hello All,

    So what motor vehicle elements do you automatically associate with the term 'Rolling Chassis"?

    I just visited the internet to make sure that I was using the correct terminology. I even allowed for some variance between Australian usage of the term 'rolling chassis' and other countries.

    What I did not expect was one organisation - okay a source not known for the reliability of its data, contradicted itself within parts of its own branches. Yes, it involves two Wiki sources.

    Firstly,

    Rolling chassis - Wikipedia
    https://en.wikipedia.org/wiki/Rolling_chassis
    A rolling chassis is the fully-assembled chassis of a motor vehicle ( car, truck, bus, or other vehicle) without its bodywork. It is equipped with running gear (engine and drivetrain) and ready for delivery to a coachbuilder to be completed.

    Secondly ...

    What Is a Rolling Chassis? (with picture) - WikiMotors
    WikiMotorswhat-is-a-rolling-chassis.htm
    The term rolling chassis is used to describe a vehicle with no engine, transmission and typically no rear end gears. The vehicle does, however, have tires and wheels and can be rolled and trailered with no difficulties. The rolling chassis can include a body and interior, or it can consist of a bare chassis or any stage in between.

    ================================================== ====================

    What I would like to describe to someone is a rolling chassis features the elements of the first example https://en.wikipedia.org/wiki/Rolling_chassis.

    Where you have all the mechanical components left after getting some form of metal cutting device and everything above the floor pan is removed - no body panels. What you are left with could be sat in and driven off and moved under its own power.

    Which of the two amount of parts do you associate with a rolling chassis?

    1) It is equipped with running gear (engine and drivetrain) and ready for delivery to a coachbuilder to be completed.

    or

    2) The term rolling chassis is used to describe a vehicle with no engine, transmission and typically no rear end gears.


    * My interpretation of a rolling chassis complies to the first definition.

    -----------------------------------------------------------------------------------------------------------------------------

    In keeping with this quest for the correct terminology - this time, linked to specified parts a body shell would only consist of the body panels from possibly the floor pan up to and including the roof, doors, windows, mudguards, bonnet and boot.

    Working along a car body from the front to the back - how far along would a 'half-cut' be? Would it be the rear side of the B-pillar? As include an unmolested pillar where the back of the front door latches to and the top section of the seat belt fixes to. Or is this a 3/4 cut?

    I am not interested in the C pillar and anything beyond it to the rear bumper bar. The back section of the car can stay put with the seller.

    If you wanted a 'half-cut' but without the engine, gearbox, suspension and wheels is this still called a 'half-cut'?

    -------------------------------------------------------------------------------------------------------------------------------

    I am seeking clarity of these terms because I am likely to be dealing with sellers, including wreckers, who are not locals. It would be good to know that I am using the correct terms. So communication would only be telephone, emails or texts. It might help avoid future disappointment when something gets dropped off; or alternatively, I go for a drive to pick something up, and it is not what I expected.

    Kind regards
    Lionel

    I have always thought of a rolling chassis as having the chassis, suspension, axles and probably the steering box.

    A body shell is a fully stripped body. No doors, windows, interior, drive train etc.

    A front cut or a half cut includes the body from sill height down and as far back as to include the engine, gearbox and dash.
    Cheers

    Thank you for your reply Slunnie.

    Okay, if you telephoned a wrecker because you were after a particular model of vehicle; however, all you wanted was from the floor pan down ... so engine gearbox and associated things like the steering column suspension wheels were included so if you want to, you could drive and stop the vehicle. Given these conditions - what term would you use to describe what you are after?

    Working from the opposite direction. If you wanted the body including all the panels and trim work doors, boot, bonnet and all the windows and the floor pan - what term would you use to describe it?

    From your responses, Slunnie - my terminology seems to be incorrect on all counts. Hence my need for seeking clarity in the correct terminology.

    My dealings with wreckers located hours drive away from me have not always been successful. Where upon my arrival the situation has been found to be very wanting at the time of collection. I would like to avoid a repeat of this less than desirable outcome in the future.

    Kind regards

    From my experience

    Rolling chassis, A chassis with just enough suspesnion and axle hardware to let you move it, IF you're lucky you get some steering gear. IF Im selling you a rolling chassis, youd get a relay box in a series but anything newer would probaly only come with everything wheels side of the drag link.

    Full body. All of the body bits, IF you happen to get it sitting on a chassis thats a bonus. For a series you wouldnt get the steering box, you'd expect the harness but not any of the heavy duty bits or parts that bolt to the chassis, Fuel pump, starter, alternator.

    Drivable chassis, Everything thats not a body component brake or steering component thats bolted to a body part. In theory, you could start it up but on a newer vehicle you might not have all the required electrical components. In a series youd be likely to get a steering box and column for a rangie or later you wouldnt expect to get the column, maybe the collapsable shaft with the UJ's but not the bit that the steering wheel bolts into.

    Front half, Take the drop saw through the vehicle at about the B pillar and make just enough of a detour to not hit the Parkbrake on the Tcase.

    Rear half, everything no in the front half.

    Dash (bulkhead for a series) forwards, cut the vehicle behind the A pillar detouring just enough to miss all the dash parts. IF its a north south setup, you get everything engine side including the clutchplates, IF its E/W you get everthing but the exhuast Typically this includes the main harness if its got wire routing (computer under drivers seat) 50/50 you get the fuel tank and pump.

    You're Rabbit holing this one Lionel...

    I'd be phoning / emailing said wrecker and stating "I wish to purchase a running wreck which is capable of being started, steered, driven etc... from a trailer to a workshop (example)"

    What you are highly unlikely to get is a wrecker willing to exert all the energy to strip out a running, driveable wreck to provide you with just the running driveline and no other pieces

    Lionel, the terminology is merely industry slang, there is no accepted standard for the term.
    Caveat emptor, due diligence and have a clearly defined inventory before departure for collection.
    If you don't like trucks, stop buying stuff.

    Generally speaking, in reply to the original question, it can be split into two categories.
    Firstly, in a professional, new vehicle situation it can refer to a new vehicle supplied to a bodybuilder for custom body completion.
    e.g. 1: A drivable chassis supplied to a coach builder for the fitting of a bus body.
    e.g. 2: A drivable chassis and cowl (panel work and windscreen forward) for fitting of custom body, such as ice cream purveyor's body.

    Secondly, in a secondhand sense, the minimum required to connect all wheels giving the ability to roll the vehicle. Commonly insinuating a foundation for rebuilding and refurbishment. Actual components included can vary widely, dependent on individual interpretation.
    If you don't like trucks, stop buying stuff.
