Jack shaft removal. Need help

[cannondale27]

Right but only if collar is stuck preventing normal removal.

All bolts are out and snap ring, Flat bar was to get jaws equally distanced from shaft, but it bent...please see my pics where I re-tried as you said, will need to hold the puller straight with a piece of wood. Aside from snap ring, anything else that could stop the bearing from moving? I am impressed how much force is needed to pull it without damaging the housing...

Have to get a straight pull or that’s not going to work. Will take a look when I get home. What snap ring are you talking about?

Yeah looking at it now. There just isn't a good spot to use the puller and have it straight. Keep in mind I have never had to do this since all I worked on the collar released at chaincase. That said can you make a steel plate to fit behind the support and bearing and then use puller on that? Other option would be to position the support to where it would allow the whole assembly to be used to drive the entire bearing out of chaincase then cut the chaincase bearing off.

Thanks for your ideas, I am also thinking to take the entire assembly in a press, which involve removing the drive shaft, chain case, manifold...not quick either...

Your idea of rotating the support worked! I was able to knock the shaft out and cut the bearing, case closed... many thanks!

That's awesome! Hate to say this but. "More than one way to skin a cat!" Right!

Any idea on proper mileage to have them looked at/replaced? Currently sitting at 2200 miles on my 18 Viper and was thinking about replacing while going through my preseason maintenance.

Mine made it over 8000mi but I inspected,cleaned and regreased all bearings annually.

I got over 9000 on mine before replacing, but I also cleaned and repacked grease every season. They were all still in good shape when I replaced only did it because I upgraded to 2017 jackshaft and figured I should replace since I had it tore down that far.

Same here. At removal were all good.

I made it to just under 11k miles. At around 7k miles I started to feel a slight vibration at varying speeds. While on a bagger trip in Canada the vibration became constant. I would not recommend waiting.
Inspect and lube as necessary every season regardless of the miles.

I will plan to take a look at everything when I get a change to change the oil and chain-case oil. Good time as I'll have the case apart already. Still can't believe how good the slide wear on my viper has been thus far.
