Podcast-In this episode we intermission down the issue of problems with pre 2006 Dyna'south & 1999-2006 spring loaded cam concatenation followers in Harley Davidson twin cam motors. The chain tensioning system in these motors uses plastic "shoes" riding on the cam chains that article of clothing out. We here at Constabulary Constant Biker all agree that in that location is no real concern with the newer postal service 2006 motors and is express to the years stated. Although we are pro Harley Davidson, this was a consummate design failure and the company should have done a better job taking care of owners of the affected years in our opinion.  You actually need to listen in to this podcast episode to go all the facts and information.

Harley damaged cam chain tensioner

What is happening on the afflicted years? The plastic spring loaded cam chain follower fails & it shreds plastic material that fouls the rotary gear oil pump cutting off oil flow to the engine. The problem is that many are experiencing failures at many different mileages, so information technology is hard to predict. Additionally, riders likely volition not hear anything going wrong. The but fashion to check the status of your cam chain followers is to dig in and inspect them. If you lot are going to exist in there for that then we suggest to merely fix the problem permanently & nosotros volition tell you how.

What did Harley do to fix the problem on the newer motors? On the 2007 and afterward motors, hydraulic cam chain followers are now used to get rid of the stiff spring that put too much pressure on the followers rubbing on the cam chain. Some believe that the problem still exists even with the new hydraulic cam concatenation followers, but we are not seeing that at all.

Our stance is that if you lot accept an affected model that yous take activity equally soon every bit y'all can and avert the impending problem all together since you tin't predict when it will happen.

S&S Cycle Complete Gear Drive 510G Camshaft Kit

The Fix #1 (Our 1st Choice):

Our suggestion is for yous to get rid of the chain organization entirely and switch to gear driven cams for the listed years. There are companies making aftermarket kits for this and without labor they toll around $750. The all-time thing is that you will get upgraded cams on top of the rest of the upgrade kit, thus more operation.  If you appreciate this Free content consider using our ii Wheel Parts Supply Affiliate Link to buy any of these kits (Due south&South Cycle Consummate Gear Drive 510G Camshaft Kit) & assistance support us.

Harley Davidson upgrade/fix kit

The Fix #2 (Our 2nd Selection):

Harley Davidson besides sells an upgrade/fix kit for around $499 (instance) without labor costs. Again, we believe that Harley Davidson should non be selling a "ready it" kit when it was their design problem in the showtime place, just it is what you may be stuck with. This Hd kit does not change it to a gear driven system & y'all don't get upgraded cams. Instead, it comes with hydraulic cam concatenation tensioner and high-menses oil pump. Harley says that the high-flow oil pump provides increased oil pressure at high-operating temperatures. Information technology changes the chain tensioner from spring to hydraulic. This is the standard fix that Harley dealerships will give you unless you want to go with the gear driven arrangement and cams, which is again our showtime proposition depending on yous budget of course.

First just wanted to say thanks for the swell content y'all guys put out. I commute a couple hours to work on an plane and the Constabulary Abiding Biker Podcast is always playing. I am new to Harley'southward, I've had a few older metrics and always accept had dirt bikes, and the service video was great inspiration in completing the service. It really is simple to complete after watching y'all guys tackle information technology on the video.

I have read nigh a potential problem with the plastic shoes associated with the cam chains. Do you accept whatsoever info on this result? This is a small quote from an article on JP Cycles.   "The problem is the design of the cam chain system. Information technology uses plastic "shoes" riding on the cam bondage that can (and do) wear out. Harley has made some changes in later model bikes, merely even with the new hydraulic tensioning system, it is not a true fix."

Justin (Oscar'southward) Original Email Response:

I am very familiar with your question, I rode a 2006 Ultra Classic for three years.  Without knowing what you are riding I tin can tell yous this:

1999-2006 Harley Davidson introduced the Twin Cam motor.  In society to run the valve railroad train Harley went to a cam chain tensioner set up up utilizing a spring loaded shoe putting pressure on the cam concatenation with push rods.  They also used, and I tin can' call back the technical name of the chain, an older chain design.  Indeed the cam chain shoes would wear out partly because of the shoe and partly because of the chain.  Harley recommended getting them checked between 35 and 40K miles.  Problem is they could requite out ANY fourth dimension and were non covered under warranty.  Generally when they get they break upwardly and go sucked up into the oil pump.  This disrupts the oil flow and tells the estimator the oil level is low.  This tin shut the bicycle downwardly.  I had not heard of whatever major engine problems every bit a issue just you would need a new oil pump and new cam shoes.

The inspection and replacement of the inner shoe is expensive and involves removing the oil pump and cam, the outer 1 shoe is easier but you have to check both of them.  Our dealership wanted $400 just to inspect the shoes, which they wouldn't practice because they said if they go that far into it they might as well just supervene upon them.  I thought, why would I replace a faulty product with new faulty products.

Harley, of course, fabricated a fairly expensive upgrade including a new oil pump and hydraulic cam chain tensioners run past the engine oil and re-designed shoes.  They too went to a new style concatenation.  The new pattern is very reliable and as of similar 2009 I haven't heard of any problems with them.  Of form the upgraded kit was similar $400 in parts and $400 to install.

I went with a gear drive cam in my 2006.  More specifically I went with the S&S 510 gear drive.  This eliminates the cam chains entirely and actually produces a little more horsepower past make the valve timing more accurate.  It was not noisy and the 510 cam produced awesome power with the stock 88ci motor.  It was fifty-fifty better when I went upward to the 95ci.  Parts and labor was around $1500.00 which included new push button rods and lifters, which is usually necessary.

Personally, in those year bikes, I would practise the gear drive cam if you lot plan on keeping your cycle for a while.  Some guys rode those yr bikes and never had a problem.  Other's had problems at unexpected times.  Harley volition tell you that if you are going to replace the shoes or do the upgrade you might also do new cams, its no more in labor because the cam chest is already open, just the price of parts and a lifetime of reliability if you lot go gear drive.

If you have any more questions allow me know, I researched the various cams, cam timing and cam lift as well every bit gear vs concatenation drive.

I watched your video on irresolute all the fluids.  I desire to do this on my own and not rely on a dealership, at to the lowest degree for this basic stuff.  So from watching the video, its possible to alter all three fluids with the bike on the kick stand.  I have been told the bike should be upright when changing fluids but from the video, leaving the wheel on the stand up works fine?  Did I become some bad data that the bike should exist upright when irresolute fluids.

My Original E-mail Response:

And then, it is not critical to accept the bicycle level. Here is the deal: Do everything on the kickstand if yous like. If y'all feel so inclined and after everything seems to have been drained, you can stand the bike upward level for 15-xxx seconds and get the last piddling bit out.  Merely, at the finish of the day that is merely going the extra mile. That is why you might hear someone say that the bicycle "has to be level".

Honestly, sometimes I do that if I retrieve, just at the cease of the day it is not critical.
