5 ton bridge truck axles

[derby]

Can anyone tell me, are the axles wider on these trucks or is it the offset on the rim?

I believe the axles are the same. I think the bridge trucks use spacers and wider wheels.

I think they are bigger but not sure......but i will take a look when i am at howards this weekend

Axles are the same, spacers are used along with wider wheels. Here's the exception, some of the chassis trucks were used or destined to be used as Honest John rocket launchers. These chassis had 10:26 gears in them. Some of these chassis were converted to bridge trucks too. Just be aware the 5 ton 10:26 gear sets are out there.

Sounded interesting, so I looked it up and as usual, Kenny is right, here is the spacer:

Spacers and bearings

Would the spacers affect wear on the bearings?

Not really, the offset on the wheel puts it right back wher it belongs

On my M821 Bridge Transport the rear axles and housings are longer than a regular 5 Ton. It only uses the spacers on the front axle. From what I have found out the reason they did this was for floation and stability purposes. I think they used this same set up on the M812 also.

the spacers are used to keep the 1400 tire from rubbing the frame and spring, some of the older bridge trucks (ie some of the 54 series gassers )had a wider axle houseing but no spacer, this ended in the same length as the newer ones, at one time someome at the motor pool rolled a old set under, who knows thinking of the military

Could the spacers be removed and use 12.00x20 rim and tire to make it legal width for highway use?

 

[73m819]

no, the 1400 tire will rub the spring and frame, you could remove the spacers, the long studs , and the 12"rim, put on the standard rim and 1100s, or 1200s and standard studs, this will get you to 8'6"

 

[derby]

what kind of cost would be involved in this swap? 10 tires ,rims and new studs? is it a big project?

 

[73m819]

not a big project, just heavy

Derby if you have the bridge truck , I'm interested in the spacers . What do you want for them ? tires too ?

 

[derby]

I do not have the truck, just looking in to one and trying to find out what i would need to do to legalize it.if I get involved with it I will let you know.

Kenny ,what is the deal with the10:26 gear set? how can I identify them?

 

[m.walker]

It's real easy to identify the gears the truck will only go about 35 MPH !

 

[BigDog]

To make mine road legal all I was going to do is put on the "super singles" and remove the front spacers. Just have never been able to save up the money!! Too many irons in the fire!!

 

[derby]

What does a set of super singles go for?

Hey BigDog what do you want for the spacers and studs ? what about the tires too ?
