The Fordson Tractor Pages Forum

Hello I bought a draw bar to my Fordson, but I am missing some parts ...

I've marked the missing parts in red ..



does anyone have the dimensions of the various pins, bolts and bracket.

the bracket and pins can I make if I could get the dimensions, since I am industrial techniques .....

thanks in advance Kenneth

The other pins are just strait ones with a strait head. Measure the holes and the thickness of the parts and you can machine them. The pin 4744 is strait with on both sides a chamfer and on one side a grove for the locking plate. The locking plate on the 119863 is a piece of flat metal with a hole for the stud and the radius is the same as the bottom of the grove in the pin.
Bold and nuts are all standard UNC threat.

Hope this helps

Now i'm just need some dimensions for the bracket 4736, and what is the 4732 for??

4732 looks like the only number that I cannot see as it is slightly off of the page. If it is the pin I think it is, it goes into the bottom of the transmission to align, and hold the drawbar casting in place. Dandy Dave!

Yes its the pin... okay so the draw force is going to the pin instead of the four unc bolts... thanks

Anyone who has the measure from flat surface on transmission down to the center of the pin 4744

Aren't there just one kind person who has the measures for til bracket under the transmission

have you tryed agriline for your missing parts or even old twenty

You mean this part?



I'll see what I can do.

They dont have that part

Hey

Thats the part

it would be very pleased if you could give me the dimensions of the bracket

Regards

Kenneth

I will see if I can find the time to draw it.

ok try cotsworld tractor spares they are breakers of tractors

Hope this will do.
If I have missed some measurement please let me know.

Henk, You ROCK!!!

Pat

Hi Henk...

Awesome thanks for the drawings

there is only missing one measure, i have marked red at my drawing



Many many many regards

Kenneth

You are right. Thanks.

What cad program are you using?
I'm working with Solid Edge

Well I am impressed with all the drawings and the skills being shown here, I kinda think there is at least 2 guys on the forum that have way to much spare time if you actually end up making this part from the drawings please put up pictures . This is gonna be something that's going to have a high degree of engineering and be beyond most of us here's ability/ machine availability ,it will be very interesting to see .

Hi Henk

I'm using Solidworks , is the red measure 101mm true or is it 100mm i was just guessed...

Kenneth

It's not a matter of too much spare time. I have to practice my skills to keep ahead of the students. Beside I like doing it. Whit these modern 3D cad programmes it's possible to draw fast. You learn a lot of these sometimes strange casted parts.

The measure 101 should be 101.6 mm.
I'm know the programme but never used it. At schools over here they use SE, SW or inventor from AutoCAD. We have chosen for SE.

Hi Henk
yes being ahead of the Students is a good thing and this is certainly good practice for you.I would not have the patience to do this,I would still be on the phone looking for the original. When I was in school sometimes i think the person that was 3 pages ahead in the text book stood at the front and taught us .
i guess this information will get fed into a computer controlled lathe and miller and be done pretty sharp too .

Nice i changed the measure ... We did try SE and inventor at work, but we feel in love in SW

And SW is working great along with my cnc mill så if i can draw it, its making it

The next step for me will be the use of EdgeCam with the use of a small CNC lathe. We do not have a CNC milling machine. BUT!!!! We just received an offer for a 3D printer. That will make real plastic components. But I guess a plastic drawbar will not do.

Have you seen delcam?? and even better delcam for solidworks, drawing and cnc program in one go

if you get that printer cant you print a pair of fenders for my major

Hi

Now i finaly got some sparetime

Bottom side is now milled



And a little film with chipping in the cnc mill

Now were talking! This is the kind of thing that makes this forum special, its amazing what some of you guys churn out, whether it be engineering skills like this or mechanical knowhow!

Looking forward to seeing the finished product here
