Intermediate Shaft

[Targa Time]

I need some advice before I do something I regret. I'm in the garage intending to replace the intermediate shaft chain sprockets. I ASSUMED that with the circlips on both sprockets and the woodruffs on the shaft that the sprockets would just pull off. Surprise! no such luck. So out come several publications. No one talks about it. Now I try a gear puller with minor effort. Still wont come off. Sooo, do I apply more torque to the sprockets with the gear puller or do they require heat first. From info on the crank, the crankshaft timing gear is removed without heat and reinstalled after heating to 300 F

Any help is greatly appreciated

The sprockets are twice as thick as the gear to give location on the shaft.
I would try applying heat or putting it in a press and trying to press it off with the heat to help. Big thing is, hear is your friend..

I was always able to get them off with a puller. I get a lot of pull on it then apply the heat until it "pops" then its pulls right off. Keep the heat on it until it lets loose. To reinstall, as you may know freeze the shaft, heat the gear and be quick and square you only get one shot at it going back together.

I just did mine. Used a large puller. It will 'pop' several times till it pulls smooth.

As for going on, a very old and talented Porsche mechanic told me to install with a smear of anti seize and a press. Crank gear as well. Went like butter!

Thanks for your input! I used a bit of a couple of your advice and it went pretty smooth. I put the gearpuller on under tension then heated the sprocket with Map Gas until the sprocket popped loose. For installation I set the shaft outside (10 F) and heated the sprockets in the oven for 1 hour. With the shaft in a padded vise I oiled the fit surface and just slide the sprocket on giving it a final tap with a piece of PVC pipe to make sure it was seated. Repeat on other sprocket.

Thanks a lot for the feed back!

you can heat it up using cooking oil yes set it in cooking oil or what ever oil you like this will head it up at the same temp and it will slid on and that it?

Most cooking oils will be smoking by that point. Use some mobil 1.

Anti seize and a press. Like butter.

That assumes you have a press.

Heat and leaving the shaft in the freezer overnight for the reinstall works.

I've always damaged the gears pulling them off, but then I pulled them off to replace them, so that didn't matter.

Walt:
Mine got stuck part way... Six times doing the heat/freeze thing.

Went and paid the $40 at harbor fright for the press (super coupon).
