Help

I have a 1966 F250 2x4

I had to replace my right hand side I beam and spindle. When i went to install a new king pin in the replacement i beam it had a 1965 style king pin. So i am trying to figure out if the difference in the spindle and beam.

From what i find the beam is the same from 65 to 66 and the spindle is the same as well. But the king pins are different. The length and diameters are the same between 65 to 66 king pin. The only difference is the location of the slot.

Both beams have the part number C5TA-8-B on them. The 65 has the number 10 as well and the 66 has 16.

I want to use the 66 king pin so both sides are the same.

Can anyone help with this?

Thanks

It is in the design of the I-beams and the king pins. The '65 I-beams are a one off, and only '65 king pins will work in them, due to the location of the keyed slot.
You apparently picked up a '65 I-beam, so you will need to use a '65 king pin, or find a later I-beam.

Before you go any further, I would double check your I-beam numbers. I seem to recall that C5TA-8-A is for one side, and C5TA-8-B is for the other. Can anyone confirm this or not for him?

Best of luck to you, and hope this helps.

I was thinking there was a different diameter kingpin on the F250's; must have been thinking of different years. Hollander shows same casting number for right and left, with '65 interchangeable as John stated, only by including original ('65) kingpin. .

You are right the -A and the -B tell which side. The numbers 10 and 16 are some sort of casting number.

I campared my 66 beam to the 65 beam and the pin retaining bolt hole are in the same place. The only thing that i can think that is different is the spindle. But everything i look up in the parts book says everything is the same except the pins.

I appricate your help.

Base part number indicates the side; 3006 for right side, 3007 for left. Spindles are same '65/66 with the exception of the 1966 F250 with 2 1/2 brakes. That spindle will also physically mount to beam. Looks like your choices are as John stated; '65 beam with '65 pin, or obtain a '66 beam. A comparison of the two pins should reveal the difference in the slot.

I would like to thank you guys I can see the difference now.

I was wondering about any additional suppliers for used truck parts . The vendor who supplied me the i beam blames me for ordering the wrong I beam. Even though i specified a 1966 I beam with casting number C5TA-8-B and they sent me a 1965 I beam with casting number C5TA-8-B.

Again as always any help is greatly appreciated.

Thanks

I don't know where you are located, but Tom at Flashback F100's can likely help.

Paul thanks for putting our name ,,,,, But it seems I cannot get through to the customer,, what was ordered C5TA-8-B and guess what was sent,, yes a C5TA-8-B was sent now where is the problem,,, he even says it in above message,,,, and now all bent up want's me to pull another saying my mistake and do it for nothing??? now somebody explain to me what I am missing here... I do know spindles on these trucks are different on the F-250 with different size shoes,,,, And of course who is saying the King pins made these days are wrong,,,,

Tom, again, according to Hollander, and as you no doubt are aware; and checking 65 and '66 beams, that is the correct casting number for both years F100/ F250, with the longer spindle still physically fitting. Just my opinion, but I would just install the '65 kingpin if needed, and be done with it!
Paul

IS It possible a difference in the size of shoes making it different, since 2 different size shoes which make the spindle different ??? can that put the hole for king pin lock bolt in 2 different locations and Ford had only one casting number BUT Drilled the hole after the I-Beam was forged ? just a thought

Absolutely on the casting number; but the spindles fit regardless, just as you said, they are machined from the same blanks. To my knowledge, king pins are the only difference. I don't know if the difference could be easily machined/ reamed, but why bother for an item which will probably not be touched again?
Again, just my opinion.

In the Ford Book I see 3 part numbers that all have a C5TZ-3511 with last letter being different On king pins kits,, in which I do know and have seen 2 different on the F100 where one pin greases on side of I-Beam and other greases on the caps so that would account for 2 of those numbers,, Then the then number goes to a C7TZ # on king pins,,, did not see any C6 casting #'s... goes right from C5 to a C7 casting number on I-Beams,,,

The difference is the suffix; normally the "A" is first issue and so on.I also have never seen a twin beam application with a C6 prefix. This leads me to believe that as you said, the beams were all forged under the same engineering number.

Do you know of any other suppliers besides FlashbackF100. I am looking for body parts. I do not wish to discuss the issues that I am having with them as this is not the place to do to do it.

Thanks

Might check out the Facebook Slick 60's Trading Post. Main caution there; the sellers may or may not be knowledgeable as to specific applications, so you will have to exercise due diligence to ascertain the parts offered are in fact the correct applications.
Paul

I will pass on what I would really like to say so,, ,,,, never mind................................................. on my

Paul I spent 5 hours today,, Guy called wanted 1973 F-250 I-Beams 6200 gvwr rating,, said had no problem give me casting # this is what he said D21A-8DA,, Well after hour in the Ford Books no number,, called him he swore that was right,, called Ford to see if my book was wrong back on the phone again and after 4-5 hours later he called and said he made a mistake and read the # wrong,, D2TA-8-DA, Only available on late 71 to 74 trucks 6200 gvwr or 6900 without a 460 engine,, after looking at many trucks finally found a pair,, he was sorry on giving me wrong info in which I was not able to do on finding that number, but goes to show give me a number and that's what will be sent,,,,, on most any part for 61/66 trucks I don't use parts numbers since I know what's going on unless a problem occurs then look in the Ford Books,, anyway it should be dropped now since I see its not going anywhers

Since you seem to not stop...insulting me. Here is the email you sent me stating that you sent the correct part. In this email you inserted my original email that I had sent you requesting the I beam. If you reread that email you will see i gave you all the correct information for my truck: 1966 F250 passenger side I beam and spindle and the casting number C5TA-8-B. You sent me a 1965 with the same casting number. As investigated in this thread the two I beams are not the same.

When you get back can you please let me know the availability of a I beam and spindle for my 1966 F250. I need the passengers side . The part number on my I beam is C5TA-8-B."
