no the pushrods dont have to be replaced...

cams, lifters, pushrods, etc all stay the same

to

Unless you plan on removing the heads/rockers, the push rods have to be replaced. You have to cut the old ones to get them out.

According to what I've read, this brand new plate is specifically for the later bikes with the older cams.  And according to the shop manual, the cams come out with the plate.  If that happens then don't the lifters and rods fall out?  Isn't that the point of cutting the existing rods and holding the lifters up with a magnet or something?
I wasn't sure of what the new proceedures were for installing this new plate....it's obviously going to be different.

I suppose....while I was in there....do the nicer bearings.....

The camplate holds the twin cams as an assembly. The older style is NOT compatible with the newer hydraulic style. But the newer hydraulic style is retrofittable to the older models if a full hydraulic tensioner conversion and cam replacement is done too. The lifters are inside the lifter bores, which are part of the case. The pinion shaft on the crank, thru gears and/or chains, spins the cams, which move the lifters up and down in their bores, which in turn move the pushrods up and down inside push rod tubes, which in turn move the rocker arms to open and close the valves. Very simply stated of course, but it explains what moves what. So as a result, as Craig said, you need to take everything apart to replace, unless you cut the pushrods and push rod tubes out. You can not us the original push rods or tubes if not disassembling everything. And since the cams move the lifters, and the lifters move the pushrods, and in turn move the rockers, were it mine, I'd be replacing everything that wears off of each other. If I were doing cams, I'd be doing lifters and pushrods too. Some say it's not necessary with rollers, but I like having all new stuff when I do this. Although, a lotta good it did me last time! Had a lifter failure anyway!

I wasn't going to point that out...but you did.

So, the new chains will not match up with the older cams/sprockets?   :-\Just asking.  spyder

To tell ya the truth spyd, I'm not sure about the chain itself. But the tensioners are different as are the sprockets. No way I'd change everything, and then try to reuse the chain anyway!

No, I was confused as to whether or not you could use the existing cams with the new cam plate kit. I know about having to cut push rods, etc....just was confused about whether the existing cams would match-up?  spyder

[naitram]

if you can reuse the cams, i wish this kits was out last year when i did the cam plate/oil pump upgrade

That's what I was thinking......just wondering what HD is thinking about 'replacement' cams with this upgrade kit?  Do they offer cams to match-up that are similar to the stock cams?  spyder

[FUZZNUTS]

So with the new hydraulics style tensioner I can expect the bill to go from 600.00(for the originals) to about 1200.00 to 1500.00 ?

But if you running gear drive and just want the new plate and oil pump I think you can reuse the cams, but not the old chain drive cams. I might be wrong, I think it's happened before!  

[TallyClassic]

Come on guys,  this is a new cam plate/ oil pump kit from hd.  And only for bikes with the older cams.  Cams are reused.  Even the service manager said so.  The only thing I have to buy is the kit. NO CAMS!

Screamin' Eagle® Hydraulic Cam Chain Tensioner Plate Upgrade Kit

This kit updates the cam chain tensioner of your early-model Twin Cam engine to the latest design, as featured on the Twin Cam 96 engine. The billet cam support plate has been designed to allow the installation of the late-model hydraulic cam chain tensionser to early Twin Cam-equipped models. These hydraulic cam chain tensioners will significantly outlast the spring loaded tensioners, and are an ideal addition to an engine modified for improved performance. In addition, '02-'06 models feature the late-model single row front cam chain and sprockets ('99 - '01 models use the existing front silent chain). The kit includes the improved late-model oil pump that increases flow by 8% and scavenging by 22% to enhance other performance upgrades.
