Front and rear Spring Bushings 5781 or CO1T-5781-A and 5781 or CO1T-5781-A

[sth65pac]

Hi All,
I am looking for a source for the front and rear bronze bushings for the springs. Part Number 5781 or Front CO1T-5781-A Rear is 21T-5781-A.

Available in Australia?
Does anyone have a solution?
Available new old stock?

Cheers,

Ian

Are original Ford parts critical to you?
I was able to get a pair of F15A rear springs rebushed at my local heavy duty truck shop this past summer. Cheap, fast and fit well.

Buy 4 and shorten them for the front?

Hi Ian

To echo Grant look for the longest standing truck spring shop in your area. How I have done it in the past, successful each time, was make up a simple drawing of the bushings and pins with lenght, I'D and OD. Then take it by their parts department or talk to them, or talk to them on the phone and email them the drawing. This process has worked for me every time.

Only problem on my HUP was getting new pins with correct locking notch but that was easy to cut the cross notch in.

Cheers Phil

Ahh now I see. It appears that the steel bush has a bronze inner sleeve, The pins are fine.
I'm thinking that the early bushes wore out fairly fast replaced by a steel one?

Ford ones are not critical, and I do have a press, so does every truck bush have the steel bush with bronze sleeve in them or doI just opt out of the bronze inner type bush????

Cheers,

Ian

Ian, Bedfords for instance just used a steel bush with (I believe) a centreless ground pin. So yes steel on steel, which may require a (slightly more) regular greasing.
You local spring maker will be able to advise.

Hi Ian,

I dug out the front spring repros I bought all those years ago. See attached.

The paperwork listed them as early F100 bushings.

PM me if you would be interested in them. Happy to pass them on for a lot less than what I paid for them if it helps someone out. They are just sitting on the shelf doing no one any good.

You would need to drill the grease access hole to the grease groove and ream the liner a slight amount for just a small clearance fit as Lynn mentioned. Didn't try it myself but perhaps a wheel cylinder hone would be enough to take out a few thou to make a good fit in lieu of an adjustable reamer.
Dimensions are:
ID: 0.740" OD: 0.998" and length 1.970" Slight size variations between all.

Hope this may be of some help.

Cheers,
