SSHD front diff repair

Same concept, but instead of a cup, you bolt the center piece to the yoke and it pushes the 2 outer caps pushing the opposite cap out. Maybe this helps.

Or you can do it the old school way with a bottle jack pushing up on the drive line yoke and heat the top yoke.

Busted many a slightly cracked bell housing the old way.

That's true on the gear box end-but not suppose to lift truck off the ground either, just some tension.

Old Cummins were pretty tender back there. Known for cracks forming we just finished the work.

I tired of the "Heat & Beat" treatment and purchased the "Tiger Tool" pullers for these jobs. Two different sizes and the installers also for the caps. Haven't torn a single anything up since, but really don't use an impact on this stuff.

Sure makes breaking a driveline easier for towing.

I have the bolt in style and worked fine for me that last several uses.

I bought the smaller tiger tool to use on newer light duty drive shaft u-joints because i tenderly used old-school methods and was concerned about driveshaft damage on my aluminum driveshaft. I haven't had to use it yet but i wanted to be better prepared for next time. My hammer skills are not as accurate as they used to be

The only problem with the thread in/bolt type is when the threads are bad. It will be yoke
time anyway. And the tiger tool will stretch a yoke. But I only have two trucks left with
full round joints everything pretty much is half round.

All on the KW are Half Rounds, Half Clamps.

Decided to try my own "invention"for u joint separation.2 plates made from my favorite building material,1" grader blades,a couple readi rods and 2 ,8 ton jacks. Just got it together at end of day,did separate one very stuck cap,will see how it pans out overall.

U-joint is most likely a 1710 series, about $50 bucks. Probably best was cut it out, replace it.

 

[56wrench]

I'd be careful with anything made out of grader blades. They can be quite brittle and break depending on how much they are hardened during the manufacturing process

 

[coastlogger]

That's interesting Wrench and thanks for the caution.I've always been aware that this could happen but have never seen it. At the scrapyard I go to the owner welded blades to the tips of his forks to extend them for picking up cars etc.I thought this was pushing the envelope quite a bit and I'm careful to stay clear when he's using them.

The homemade puller worked a treat .spent most of day removing diff from parts truck. Looks really good so it should get me mobile again.Got a call from truck parts outfit saying the sliding clutch collar in my sshd power divider is a no longer available part .sooo will have to figure out how to break it to wife that we need anothe 1980s vintage parts truck .anybody know a supplier that might have this part?or is there something about using a power divider from a different vintage?

Hagerman Truck Salvage Umatilla, Or.. Ask for Randy Gibson he is a outside sales person now but spent
years working as a gear man. Randy is a good guy and can find most anything gear related.

Tell him Mike at Tate sent you-I've known Randy for 25 years, honest he is.

 

[Birken Vogt]

My dad has made anything and everything out of grader blade scrap over the years and it does not break much. I don't think it is brittle, tough might be the correct word.

 

[coastlogger]

Thanks for that contact I'll call him.

Well the program suffered a setback today. Seems parts truck has 5.29 diffs and old ones are 4 point something.I had compared the specs when I bought the parts truck but I guess someone changed something in last 40 years .
.Changing out both diffs.The lower gear ratio will I blv be better for my work,lots of hills etc.
Should be a qualified diff changerouter by the time I'm thru I guess,for whatever that's worth .

 

[crane operator]

Would it be easier to steal the sliding collar from the 5.29 and put into the 4.???
