Jordan,

this may be of use to you once you have the sizes sorted.

My local heavy duty truck shop in Kingston makes U bolts to order, you spec it, they quote it and make them.

If you cant find what you need I am happy to help get them made for you.

I asked them to quote a job and was of the opinion that they were value priced to the point I could not make them for the money they wanted.

Good luck.

Agree, a spring/suspension shop is what you want. They can hammer out U bolts to whatever spec you give, and for prices similar or cheaper than the Cdn tire stuff.

Default Wood blocks at U-bolt locations?

Hi Jordan

I remember see something on varrious CMPs about blocking in the frame rail and body rail at the U-bolt to keep from deforming the frames. My HUP has oak block, remember also service bulletin about adding blocks or adding a steel plate to box the frame at the U-bolt locations.

Cheers Phil

Although they are listed in the Body Parts List, I could not find info re. their sizes. If you want I can go measure them up and make some reference pictures?

Default U bolts??? Are we sure???

Are we sure they used U bolts?

All the CMP I have seen had long bolts going through thick plates to both the bottom of the frame and on top under the box???

If U bolts are used they would need to be installed up side down...U pointing up... and a 1/4 inch on top. They will not fit otherwise in the right space un de the frame. Very critical dimensions on the length of the U bolt as the top threaded end must fit the exact thickness of the frame plus the wooden spacer und the box and still have enough length to instal the top plate, lock washer and long U bolt nuts....if the U bolt is too long, once the boxes sits on the frame you will not be able to fit the nut.......

I have fabricated long bolts with plates at both end as that is the only way I have seen them installed......... Could it be that all the trucks I have seen had the boxes removed and reinstalled with bolts and plates sometimes in their career??

I have seen wooden blocks to stiffen the frames..... made of thick hard wood and groved on the inside portion to allow the inside bolt to hold it in place.......

Comments!!!

Box is a 2C1 on my 1943 F15A Cab 13.

U-bolt at rear of chassis:

Mid-chassis, this one has a spacer block:

These are bad phone shots, I can make proper pics and take dimensions.

HTH,

Default Thanks Hanno

What are the dimensions of the bolts.....half inch or bigger and thickness of the plates??

Now for my next question...... where do we find spare parts listings for the cargo boxes???? All my manuals deal with the chassis, cab and mechanical components....... was there another manual for the box components????

Thanks

For those who may not know, I have Alex Blair's manual collection and the only reference to body construction is 1941 version reference in the post Hanno links to above.
I don't have material on the Lindsay construction for the house bodies or the for the later steel cargo bodies (and the machinery bodies made from them).
Also not known are the construction details for trailer bodies (except that some of them are very similar to the later steel bodies - may use some identical parts or sub-assemblies like tailgates).
I would be happy to hear from anyone with details mentioned.
