Technical Pics of your front shackles with dropped axles

YEA!!! Glad you got it.

Is that a 35 truck? Gonna need some pics...

-Abone.

 

Dude, you know me….go to the LeGrange Produce Tribute Thread.

Looks a lot better with the shackles flipped the right way; but would have thought they would have been sitting flatter without the weight of the engine etc.

 

are you sure the shock mount "thingie" doesn't need to go to the other side of the car?

Not sayin' it very well, but if both of them were changed to other side ? just sayin'?

 

Not sure. I'll have a look at it when I get some more time.

 

40 Ford with 4 inch dropped axle and Posie reversed eye spring.
Shackle should be at about a 45 degree angle.

 

I used to make the 'triangle' shackles to mount shocks, not my idea; I stole it from a '34 in the 'Little Pages', back around 1953! Glad to see it back, lots better than that cockeyed add-on 'stud' below the spring hanger. (and that long, soft repro hanger!)
Some guys like 'em, but every one I see is crooked after a few miles...or ends up welded onto the lower yoke of the wishbone...the ones with keyways sheared off, unless the shocks were so soft they were ineffective.

 

not applicable. wrong subject. IMO

 

not on subject,, IMO

 

verde742, how on earth was my post not applicable and wrong subject???? What was the heading?? The photo I posted show front shackles on a dropped axle, that photo alone would have shown the OP what the problem was with his front shackles or is it just because the spring is in front of the axle, we didn't know that then but it would have still sorted the situation out.......which it did. Cheers for your concern. JW

 

OK, take me off yer list. I thought about the 3rd picture down it showed a '36, which have spring in front of axle: Then comes yers with spring on top.... But then I am old.

 

I'm thinking if you used a stock off the shelf 35-40 spring with a narrow CE axle that the the spring is just still too big

 

What is the difference between the perch bot centres on this CE verses a 35-36 axle?
verde742..we're good. JW

 

35-36 axles have 36 1/2" perch centers according to Sids site. CE says there are 35". When I ordered my CE axle I was told they were now shipping SoCal axles, which were the same as theirs. However the axle I received is 33 1/2" . Certainly moves the bones farther in for tire clearance. It is a 47" wide axle which is the same as theirs. I can vouch for the fact that Speedways 35-40 Ford front 4 bars will not work with the SoCal axle, if that is what I have. No logo on it.

 

Look at these two again. Wrong or right aside, the shocks will be different as the compressed and extended lengths look to vary by over an inch.

 

I haven't thought about this for a while, I've been on other parts of the build. I will revisit this soon.

 

Just to stir the pot a little!!!
Here are two shots of my roadsters spring/shackle attachment.
Anyone recognize this setup?
Hint: this is only used on one side, the other side is your typical shackle arrangement.
Now this is where you old dirt trackers can give everyone an education on it's merits,
explained much better than I can I'm sure.

 

Yip, the dead perch, used on the L/H side of the front spring ( for L/H turning) to prevent shackle swing. JW

 

I ran a dead perch on my deuce roadster back in the 80's worked great. That roadster was kinda unusual for the times as it had the dead perch front and 1/4 elliptic s in the rear. One of the best driving and riding roadsters I have built.

 

The shackle is facing in the wrong direction, spring in front the shackle should be dropping down. A way to remember this is that when you want to lower a car with spring in front (or behind on the rear) to install longer shackles thus dropping the spring eyes lower in relation to the axle center line.

 

So who makes that "triangle" shock mount thingy that replaces the end plate on the shackle and will that work on an AV8 with drop axle instead of welding a bung to Henry's steel?

thanks,

Andy

 

I recognize the setup I think its called a dead perch or something like that, you have one dead side and the other has a shackle. I can never remember which side is dead though, I want to say steering box side but I am no doubt wrong about that.

 

This was my old mordoor sedan. HRP

 

They make two versions of the dead man perch,the one that DDD posted and this type that is show on the last post.HRP

Since you all are on the topic......I think my shackles are at the wrong angle.? In this picture I do have the vehicle on jack stands but if it's on the ground, my shackle angle only slightly angle OUT. I want the front height raised anyway so I was going to swap out the "reverse eye" with a "regular eye" spring. If I'm hearing you all correctly, my resting shackle angle should be 45 degree facing inwards.....right? I know Posie has a method (King Pin center to center and Spring Perch center to center) to measure so I will follow that.

 

Your spring is too wide. JW

 

I know it ain't Vern Tardel, but the "Speedway" catalog has some charts referencing perch centers and spring length. Also says that under load, shackles should sit at 40-45* . I don't have the accumulated knowledge of some of youse guys , so this helped me out. Good luck with it- your avatar is freakin' KILLER, Mr . Roothawg!

 

maybe a bit late, but dont forget to put the nut back on the perch bolt!

 

The opinions out today, say the front panhard works better than a dead perch. Also with a front panhard the shackle angle is not as critical. More vertical angle on the shackle lets the leaf spring work more freely. So if your shackle ends more straight up and down, it should not matter much.
