Hey all, I'm installing a pair of cams this weekend and have a question to those who've done it....

I have the manual and the directions a pretty straightforward...i KNOW i need the 'oil pump alignment screws'- those are imperative....but do i really need those thing which appear to be 'luxury' tools like the 'cam base' and the 'cam guides'

Any advice would be greatly appreciated!

Paul

Hey paul

hard to know what you have and do not have as far as tools go. Feel free to call me and maybe i can give you a few tips/ tricksto work with the current tools you have to get the job completed. hope that helps some. You really did not list much info , chain drive, gear drive, reusing pushrods, size of cam, year of bike etc.

Yikes....you're right....sorry about that, man

it's an 07 Street Bob...installing HQ 'hurricanes' (chain drive) and a set of EZ install adjustable pushrods ....I have a pretty complete set of tools outside of the specialty ones required for the job- besides, the oil pump screws

sorry for being so vague, before

pretty straight forward..I don't think you need the align. screws if you don't mess w/ the pump...if so you can finger tight them then snug them up slowly while spinning rear wheel in 5th gear.(by hand) the pump will align.this way.. I hope you got the tubes w/ the adj. p. rods cause w/out em. it's tough.. why arn't you going Gear-drive?? Cost?? crank run-out?? you can do it w-out the tools it's just harder.. Steve

Paul,
Now you'r in the right place! [:@]

Here's some stuff I got from DALTON and others:
If I had to pick between the two cams, I would go with the Andrews 37. You
can align the cams by loosely fastening the pump to the camplate and
rotating the engine while sugging up the oil pump bolts. Cam timing is set
by matching the "dots" on the cam gears. You will need to get a new cam
cover gasket, you could reuse the pushrod tube o-rings and cam plate
o-rings, but for the cost, i would replace them. No special tools needed to
do this it is a simple process. You definitely will need some sort of fuel
management system. If this is the old mod that you plan, a DFO or Terminal
Velocitry tuner will work but I would really recommnd a Power Commander as
you have the option of more map that will put your tune very close to what
it needs to be. Hope this helps

And:
Nope, no exotic tools necessary. Bring the cyl you are working on to TDC, cut the pushrods, bring other cyl up on tdc, cut the pushrods. Using binder clip wire, lift and hold the lifter away from the cam. Pull the cam cover, pin and pull the outer tensioner, pull the crank and cam gears and chain, remove the oil pump bolts,, pull the cam support plate, and you have it! Cams are ready to come right out. This is an oversimplification , as youmay have to deal withthe exhaust and a few other small items prior to digging in to the cam chest, but it really is that easy. No press required and no exotic toolsofor cam swaps in the 06 dynas andall 07 and up twin cams.There are oil pump alignment pins that you can use but there is also an alternative method for centering the pump when you re-install. There is also a tool used to keep the gears from turning while you tighten the cam and crank gears . A piece of soft pine into the teeth will also work with out damage. Easier with the correct tools, but not something that you cant do with a little improvisation. The one really necessary tool you need is the service manual. It details where the o-rings go, torque values and how to align the cam gears for timing and also the alternative way to align the oil pump
Hope this helps!

wow!...thanks Lab!....that works....i visualized everything that was outlined in your post.....what i did forget are the gaskets....i have a local dealer i can get those from....no biggie...thanks, man!...much appreciated

Yep, worked for me.

I don't know..it looks like the oil pump has to come off in order to get the cam plate off in order to get the cams out...???.... that's the way the directions read, anyway

All the fasteners have to come out of the pump/cam plate to get the cam plate off. You can't change cams without disturbing the oil pump.

put new oil pump o-rings in while your in there, and cam chain tensioners, it's all good insurance.

I would not go that far without changing the inner cam bearings. If you elect to change them, you will need the puller and installer for the "large" inner bearings ('07 and up).

there's really no need to change the inner cam bearings unless they're really worn...and at 3k miles, i'm sure they're fine

You can take the 4 screws out of the cam plate that secures the pump to the plate, but you do not have to remove the pump from the case. I would still change the inner bearings to Timkens. Also change the oil feed o-rings.

yeah, oil pump doesn't actually have to come off... i can see that, now... but man, the bearings are fine... i don't want to go pulling them if I don't have to...bike only has like 3k on it
