Rear gear ratio change?

Hey Everyone,

I am looking at an International 3800 shorty. It currently equipped with 6.13 rear gears.

I can get a used, warrentied "drop in" with 4.88 or 5.38 gears for about $800.

Can anyone tell me what the labor involved in changing this would be and what I should expect to pay a shop to do it?

Thanks.

S.

IDK what labor would be.
Does it have OD?

It does.

It has a spicer 5 speed OD behind a T444. If it was a DT I would be in hog heaven.

Why pay a shop to do it? With a “drop in” all you need to do is change the third member. Jack it up pull driveline, pull axels, pull third member, (with the appropriate jack). Install third member, install axels, install driveline, done

Easy peasy 😁😁 perhaps three hours tops.

You will of course have to replace differential lube.

actually do not even have to jack it up, the bus that is. I do not jack up to change the third member. It is easyer then one might think other then these are a bit heavy.

differential gears

That center section lump is going to be pretty heavy. If you do not have experience changing a center section, you can still do this but depending in level of experience it can be daunting. And dangerous. That center section landing on your face could kill you. Landing on your fingers, could amputate fingers.

You will need a torque wrench. you will need gear oil. catch basin for the oil. anti seize compound would be good. And torque specifications. some clean rags, some sort of solvent and a muffin tin to put nuts and washers in.

If this is a two speed rear end -- I dont know how they are put together and all bets are off.

a floor jack is needed, transmission floor jack would be better. with out a jack you will have to make some sort of way to get the old diff out and back to ground level and the replacement diff up to the housing and back in.

A shop with experienced, good mechanics, can do this in less than an hour. If every thing comes apart and goes together well. Assume most times for two hours.
Never done one before and making due with equipment less than perfect for the job, a day.

Air wrenches with an air compressor make the job much faster. transmission jack will speed things up. couple of ratcheting tie down straps. A manual that has torque specifiactions, for the axle shaft flange bolts, drive shaft u joint bolts, differential to housing bolts.

find u tube videos and watch how to do it a couple of times...

U sure its got OD?
From what I understand most of the spicer 5 speeds are 1:1.

two speed rear does not make any differance to changing except would take off the motor for the rear.

Most people would not do this job at home, so not saying jump right in, however it is not as scary as some might think it is. I have done a number of them.

So what's it worth money wise in labor?
