For those curious on pulling inner cam bearings ..........

This is part of the tool set to R&R inner cam bearings.
Here the tool is in the bearing (snaps in) but the center expanding rod is not installed.

[porthole]

Here the center rod is inserted all the way. This expands the collet that the bearing sits on. Expanding the collet keeps the rollers from falling out of the bearing, which is bad, because Murphy's law says the rollers will fall into the case

Remover inserted in bearing

Bearing remover plate installed on cam chest and tool set to begin pulling

Two wrenches, one to hold the remover and one to run down the nut, which pulls the bearing out.

That's it for now, Bob has to order some parts!

Porthole, can't thank you enough for this - giving me an idea of what I am tearing into before I have to do it make it MUCH easier.

Hope it all goes back together well.

Sean - If you are mechanical it is not that big of a deal. SO far the hardest part was getting the front exhaust pipe off. Had to just about break one nut-bolt for the center clamp, had to cut the "T-bolt" clamp for the muffler and had to break 2 of the 3 hose clamps for the heat shield.

I'm adding the pictures because the book leaves a few of them out.

My former career had me doing this stuff all the time, just not on bikes, so I have most any tools I would need, except for the speciality items.
I expect the re-assembly will be no big deal, just don't have any parts yet to get an idea of what I will be doing.

Still trying to picture in my mind how the gear drives work - since the chain keeps everything in rotational order and gears change direction without an idler in the mix.

Is that scoring/wear normal?

This is the first twin cam pump I have seen, and with no previous experience I would say NO. I do wonder why though there is no iron sleeve for the gerotors or a cast iron pump housing.

Now that I know the pump alignment procedure I would venture to say if the dealer was doing this job the odds are good the extra time needed to align the pump would be skipped.

Fom the Hot Bike mag website.

15. He removed the cam plate and snap ring and pulled the inner cam bearings. The new Torrington cam bearing (shown here on the left, sold separately) provides more surface area contacting the cams than the stock cam bearings. Side Note: Before installing cams into the cam plate, you should dry fit the cams to check lobe to case clearance. Check both cams, and if they spin then you're good to go.
