Crankshaft tone wheel replacement

[Volvo8873]

Not!!! going to get into why this happened in the first place but I need to replace my crankshaft tone wheel on my truck as a few teeth are chipped off. Seen on quickserve the installation procedure which involves heating up the crankshaft adapter to 500 degrees in an oven. i have the means to install it but am wondering the means of taking it off?

Seen Rawze has mention in his video that a 50 ton shop press is needed. Maybe a big ass torch with a long while for heating up the adapter is all that is needed? I have not found much info on this is why I am asking. Maybe it will help others down the road.







Oh I had dropped the oil pan also after after front structure to make sure that Inhave all metal teeth and any bits. Which I do.

There should be a procedure on quickserv somewhere to drill into it from the face using a certain size drill bit at a certain depth to "split" it and then it can be taken off without a press.

I came across another post about this but have not found the procedure. Maybe someone can steer me in the right direction?

If you go to Allison's video from haggai they don't even put New tonewheels on they have a company come in and do it


Nut-n-but isx. On YouTube. Just truckin seems to have got her on the tubes for our benefit

Since I have a few beers in me I thought I would update this post.

I ended up fixing this and now have about 60,000 miles on it now. The job was actually easier than what I had anticipated. I used the drilling method (thanks rawze for that link) and the barbecue to heat up the tone wheel and adapter. I then took a rosebud torch and heated it up to get the adapter up a little higher than the 500 degree mark that cummins states. Both the tone wheel and adapter slipped right on with ease and I held it in place for a good minute or 5 it seemed! lol then I proceeded to put the rest of the front structure back together.


Just letting everybody know make sure to take out the 3/4 wrench when you are barring the motor over to help when adjusting the clutch! lol I bumped the starter to roll the motor over and it preceded to break apart the adapter that goes on the air compressor which in turn I "assumed" was ok after realizing what I have done. I went down road and the chunks proceeded to get caught in the gearing which proceeded to crack the front structure housing which dumped oil out 1 mile all down the road. I limped it back to the shop which I realized my stupid stupid stupid stupid mistake!!

I had to drop the oil pan and inspect bearings and oil pump along with all the gears in the front structure cleaning out all and any possible debris followed by a few quick oil changes. Camshaft and rockers are fine from what I have seen. Not sure what to expect after all this but it seems to be fine until I overhaul this motor in the very near future. Which will be a total overhaul. I guess I can call myself extremely lucky and an idiot at the same time. I was expecting the very worst.

Just an FYI I had done a front structure gasket job myself on this a few months prior to this happening. I used neverseiz for the new crankshaft dampener and motor mounts when putting it back together as you can see in the photos the gray paste.
