Thread: Penfold

I have a bit of a question on springs.
Mine rear springs have been off to the press for new bushes. Time soon to refit and I have noticed some differences in the eyes and need to know if how they go back is going to be important. I marked the springs left and right as I read somewhere that was important but front / back was not mentioned. Ok start with the drivers side.
One end looks like this:

And the other like this:

The eye of the spring is offset.
The near side has an offset but equal:

Does is matter? Has it the offsets appeared through use? I don't find that likely.

Any info gladly accepted.

G'Day, As far as I am aware the springs are definitely left and right , the right springs have more camber in them to allow for the weight of the driver and fuel tank so the LR will sit level , but I don't think the spring has a front or back ie direction , it'll be the same facing either way. In your pic it just looks like the bush has pushed out a bit and not central in the eye.

Springs are handed, right has more camber. Front and back are different.

The offset you note will have occurred during service, and does not matter unless the spring is rubbing on the shackle or hanger, and even then is not that important.

Did you get your fuel starvation problem solved? Likely to be an air leak in the suction line from the tank (or the screen on the bottom of the vertical pipe into the tank blocked), or, alternatively, an ignition problem, most likely points, but could be capacitor, coil or HT leads. These can do a very good job of mimicking fuel starvation. While a parly bocked carburetter jet is possible, this is unlikely to give the described symptom.

Thanks guys

The bushes are freshly pressed and flushed so it looks like deformation of the spring, which is surprising. Must have gone round a lot of corners.
The fuel problem I am working through. The car is not on the road so I cannot tell if I have fixed or not.

So far I have:
- rebuilt the carb, (including lapping the cover faces
- checked the tank uplift pipe (all ok).
- checked the line from tank to pump (this was clear but I am not sure how to check for air getting in?)

I have been told that there could be issues with fuel vaporizing in the line as crosses the engine.
I really need to get the cross member welded and the tub back on and give it a run.

Can be very difficult - one method is to pressurise the tank, about 5psi and look for leaks, but this is not infallible - the leak may be acting as a one way valve. The likely places to leak air are any of the joins in the pipe, and inspect it carefully for damage to the nylon tubing, and also suspect the gasket on the sediment bowl on the pump.

I have been told that there could be issues with fuel vaporizing in the line as crosses the engine.

Very unlikely, as the fuel is under pressure here, although this could be where the problem shows up if the pump is sucking air.

The spring situation will have arisen because there is a steady sideways load on the spring. This could simply be consistent driving on steeply cambered roads, but could also be because the three attachment points of the spring (dumb iron, shackle, and axle housing) are not in line or the spring is consistently twised sideways, which will happen if the vehicle leans.

The pad on the axle housing holds the spring flat on the axle, but the chassis is leaning - the leaf with the bush held in it will be kept twisted by the bush, but the other leaves will only be held twisted by the spring clamps, which will wear, and allow them to straighten somewhat, with the results you see.

Thanks

I think I will just replace the fuel lines. I noticed that the wire that retains the sediment bowl is not seated in its spot on one side. Long shot but I will take care of that.
I also have new condenser. The leads and distributor cap are a fail though. Old leads are screw type and the new are push type. Also the lead for the coil is way to short. Thank you britpart.
The springs will have to be a guess I suppose. It sat quite well before they came off but I never looked too closely.
I hope to cut the steel for the x member repair today. I need that fixed before the springs and axle go back.

Give the boys at Performance Ignition a call About us they can make you a set of Magnecore high-tension leads and you will never need to replace them again.

They are across the other side of town from you, but they are the premier experts at anything to do with ignition systems,

Cheers Charlie

If you lost track of which spring is left and right, simply put the one with the more camber on the right. If they are original, the springs should have the part number stamped on the convex side of the eye, facing down, at one end.
