Prop shaft rotation
Avoneer - 23/5/05 at 12:13 PM

Looking towards the front of the car, does the prop spin anti-clockwise when driving forward?

I'll tell you tonight if nobody has replied beforehand but from visualising it in my head, I think you are correct. Find a picture of a Sierra / English diff and you can work it out from that, if I recall correctly the crown wheel is on the passenger side when mounted meaning it will be anti clockwise

no it turns clock wise..

My vote is anti clockwise still

Here's a pic of an English diff



The flat edge off the diff nose (top right in the picture) is the bottom of the diff when mounted in the axle, therefore the crown wheel is on the passenger side of the car. If you roll the car forwards the crown wheel will turn in the same direction, which means the pinion (and so the prop also) will turn anti-clockwise - I think

anti-clockwise

just checked


tks - 23/5/05 at 06:09 PM

i´m not mad...

think of the blade engine pallss..

to turn the wheel going forward it needs to turn anticlockwise looking at sprocket okay???

now put the engine in the car

if you stand in front of the car lokking at the radiator from the front (via the nose cone entrance)

then it turns clockwise..

easy job..

Just working out if I need any extra bracing for the engine and wanted to work out which way the torque would try and turn it.

Looking at the engine from the front it turns clockwise, whether it's a bike, pinto, zetec or whatever.

Not always Pete, some of the Honda engines run anti-clockwise from the front.
Cheers,
Craig.

Yeh but Pat didnt say that
He said "Looking towards the front of the car", ie standing at the back and looking up the bonnet as if sitting in the car

But wherever I look at it from, the prop still goes in the same direction. He didn't say he was sitting in the car and I look towards the front when standing in front of the car. I therefore maintain that the prop spins clockwise wherever you look at it from or the car would go backwards if you stood behind it. If you stand behind a clock does it go anticlockwise or does it appear to... Pat's not fitting an anticlockwise engine Craig, and even Honda realised they'd got it wrong on that one.

Sorry guys, should have said "sitting in the drivers seat and looking forwards" - that would have made sense and everyone is right.
Cheers,
Pat...

Eh??

As a figure of speach surely you look towards the front if standing at the rear of the car, the same as you look towards the front of a cinema when watching a film even if you are right at the back. Face towards the front means looking forward in the direction of the object, ie same way as the car is pointing.

So if looking in that direction the prop turns anti-clockwise. If you look at a clockface from the back then that is also going anticlockwise, the description "clockwise" or "anticlockwise" doesnt change just cos its a clock you're looking at from the back, clockwise is always hands going to the right when at the 12 o clock position !!

All the cinemas round here have the doors at the front and the screen at the back . Sorry Chris, Pat's got it right now by changing his phraseology so tks and I can understand it.


ChrisGamlin - 24/5/05 at 09:40 AM

So if you get front row seats at the cinema you expect to sit behind everyone else by the doors do you?


Peteff - 24/5/05 at 10:41 AM

If you don't quantify then a statement or question is meaningless is what I mean. In the words of Homer (Simpson, not the Greek bloke), bah, you can prove anything with facts .

P.S. Those are first row seats not front row, or there would be front row, back row and all the ones in between would be middle row.


ChrisGamlin - 24/5/05 at 11:05 AM

Hi Pete

Don't worry, I sort of see where you're coming from (apart from the seats/rows thing which is bollox ) , but it does strike me as fishing for an escape route here cos to most people I think "looking towards the front" means looking the same direction as the driver looks when sitting in the car, regardless of where they are standing.
We can forgive TKS as its not his native tongue, but you are not forgiven


Peteff - 24/5/05 at 11:54 AM

Another vaguary, it just gets worse for me. I've had a lifelong struggle to understand other peoples logic. I don't think tks and I did anything that needs forgiving, anyway I'm bored with this now I give up. I'm happy to be one of the few and not like most people . Check the sig Chris, I think it's relevant here.

No probs, twas only a bit of light hearted ribbing
