ValveTrax®

Adjusting valve lashes on your engine just became Easier, Faster, Safer, Consistent and with Precision by using a new tool called ValveTrax®!

What is ValveTrax?

Welcome to ValveTrax!!

ValveTrax is a newly patented tool for the engine building industry that helps the user to adjust the valve lashes on an engine Easier, Faster, Consistently, Safely, and with Precision every time!!  If you are sick and tired of re-adjusting your engine valves over and over again after starting your engine up to eliminate all those ticking noises due to miss-adjustments and guesswork trying to maximize your engines performance, then the ValveTrax tool is for you!

ValveTrax is a strip of white vinyl with a magnetic backing that temporarily wraps around the harmonic balancer or a V-Belt pulley or a Serpentine pulley and displays to the user with color graphics exactly which valve to adjust with respect to the rotation of the crankshaft.

The ValveTrax tool is made to be used on any engine using valves, any number of cylinders from 3 to 28, with any Firing Order, with any Crankshaft Offset, clockwise or counter-clockwise rotation, any size Diameter harmonic balancer, V-Belt, or Serpentine pulley, and any Reduction Ratio.  Whether you are working on your automobile hotrod, boat, farm tractor, aircraft, or industrial engine, the ValveTrax tool will work perfectly on your engine to make those valve lash adjustments almost painless and saving you a ton of time and frustration!

Engine manufacturers, factories, rebuilding shops, machine shops and repair shops currently adjust valves with hydraulic lifters on an engine by using the procedure in an OEM manual which is to first manually rotate the crankshaft until you reach Top Dead Center. Adjust half of the valves until they feel snug and then adjust them another 1/4 turn, or 1/2 turn, or 1 full turn or 2 full turns, or whatever. Rotate the crankshaft again until you reach Top Dead Center again and do the same thing with the other half of the valves. Using this apparently simple procedure is that most of the valves are adjusted too tight on purpose in the hopes that they will “back-off” eventually with the self-adjusting rocker arm nuts. However, most of the time not all do where those valves may or may not fully close and therefore, the engine will never reach its maximum efficiency but will be…..“good enough for the basic consumer”. Adjusting valves with solid lifters, one has no idea whatsoever if they are on the base circle or on the ramp portion of the camshaft lobes and therefore, can easily have the valves adjusted too tight such that they never fully close. For most hobbyists and race shops, this procedure IS NOT good enough where they take it one step further; start the engine up and re-adjust all the valves again while it is running until all ticking noises are eliminated. This works, but not without some drawbacks and safety issues such as the following:
 

1.  If you started with a nice clean engine, it won’t be afterwards because engine oil will be splattered all over the engine bay as the valve covers must be removed to make the valve adjustments.

2.  If your hand or arm accidentally hits the fan blades, it will dutifully slice them up.

3.  If you are wearing gloves or long sleeved shirts or ANY jewelry, the fan blades or pulley belts could grab your clothing or jewelry and pull them in.....very nasty results!

4.  If you accidentally drop a tool into the fan belt area, it could damage the tool, the belts, the pulleys or anything else in the vicinity, and could actually throw the tool back up into your face.

5.  If you accidentally drop a tool into the valve train area of the cylinder head, it could damage the tool, the push-rods, the rocker arms, the valve springs, or the valves themselves.

6.  Engine oil will be hot enough to burn the skin, and even if it isn't hot enough, the skin will do its best to absorb the oil like a hand lotion, but it is not good oil for the skin, it is toxic oil.

7.  With hot engine oil, there will always be fumes where a lot of the splattering oil will land onto the exhaust manifolds burning the oil further and thereby giving off more fumes. These fumes will make contact with your skin to be absorbed, or they will make contact with your eyes to be absorbed, or they will be absorbed by your nasal membranes, or they will be inhaled through your mouth to be absorbed by the tongue, gums, throat, wind pipes and lungs......are you ok with that?

8.  The whole process of re-adjusting the valves again may take a couple of hours or more depending upon how many times you need to re-adjust the valves to “get ‘em right”.  How much of your day are you willing to waste away doing this tedious job when it could be done in less than half an hour?

9.  When finished, you will spend a lot of time for the massive oil cleanup your engine has dutifully splattered all over your engine, the engine bay, your garage floor, and wherever else.

10. Lastly, the ValveTrax tool keeps you organized during your whole valve lash adjustment process.  If somewhere during the middle of your adjustments, you need to take a break by taking a phone call or going to the bathroom or to address any issue for whatever reason, when you come back to finish your adjustments, you will know exactly where you left off.  The engine pointer will still be pointing at the graphical location on the tool such that you will know what valves you have already adjusted and what valves still need to be adjusted; it keeps you organized throughout the whole adjustment process!  Again, saving you more time.

The ValveTrax tool is used with the engine shut off such that it not only allows you to keep a clean engine with no cleanup afterwards, but also eliminates ALL of the safety issues listed above and saving you a tremendous amount of time.  Besides these benefits, the end result for you is your engine will be able to achieve maximum horsepower potential, maximize its “gas mileage” potential, and minimize overall emissions for the environment....all good stuff!

The pictures below show how the ValveTrax tool is attached to a Harmonic Balancer, a V-Belt Pulley and a Serpentine Pulley:

When you order a ValveTrax tool, you will be asked to select all the Options that I need for your specific engine configuration as explained by the following list, and although this list may look overwhelming, rest assured that most of them are already set to a default value so you really won't have to change very much: 

Balancer Type                               You need to tell us what you are going to use the ValveTrax tool on such as either a Harmonic Balancer, a V-Belt Pulley, a simple Disc, or on a Serpentine Pulley.  The tool for the Serpentine pulley will be slightly shorter in length due to the pulleys' smaller inside diameter, but don't worry as we take that into account when you give us the outside diameter.

Rotation                                              When you look at your balancer or pulley from the view that you will be adjusting your valve lashes from, what direction will you be rotating it.....CW or CCW (clockwise or counter-clockwise)?  As 99.99% of the time your view will show it in the CW direction, most aircraft engines will be in the CCW direction.

Intake Centerline                          Simply use the pull-down menu to select the value for your camshaft, anywhere between 100° and 120°.

Lobe Separation Angle           Simply use the pull-down menu to select the value for your camshaft, anywhere between 106° and 116°.

Crankshaft Offset                       The default is  for most engines, but if you know what the crankshaft offset you have then you can select a value from either the Advanced (-) or Retarded (+) pull-down menus.

Reduction Ratio                           The default value is 1:1 for most engines and keep in mind this pertains to the ratio of a gear box connected between the crankshaft and whatever else you are attaching the ValveTrax tool on such as a disc for a propeller shaft on an aircraft engine, as most propellers rotate slower than the crankshaft and therefore, the ratio is something greater than 1:1.  As you can see, Reduction Ratio IS NOT related to any transmission gear ratios or any differential (rear-end) gear ratios.  If the reduction ratio you need is not on the list, then select Other and go to the Other Reduction Ratio option as described below.

Other Reduction Ratio            If the ratio you need is not in the Reduction Ratio pull-down list above, then simply enter the ratio you need here.  We will also update our database and this website with this new value.

Balancer/Pulley Diameter   You need to tell us what the outside diameter of your harmonic balancer or pulley is, so we can make sure the ValveTrax tool is at the correct length for you.  Simply use the pull-down menu to select your diameter size in inches.  Check the Diagrams page to see how to measure the outside diameter.  If the diameter you need is not on the list, then select Other and go to the Other Diameter option as described below.  If you cannot determine the diameter for whatever reason, then wrap a tape or string around the balancer to measure the circumference.  Then, select Circumference and go to the Other Diameter option as described below.

Other Diameter                             If the diameter you need is not in the Balancer/Pulley Diameter pull-down list above, then simply enter the diameter you need here.  We will also update our database and this website with this new value.  If you selected Circumference above, then enter that measurement here.

Firing Orders for 3-Cylinders thru 28-Cylinders   Now, you must tell us what the Firing Order is for your engine, so simply scan down the whole option list for the number of cylinders you have and select the Firing Order you need from that pull-down menu.  If the firing order you need is not on the list, then select Other and go to the Other Firing Order option as described below.

Other Firing Order                      If the firing order you need is not in any of the Firing Order pull-down lists above, then simply enter the firing order you need here.  We will also update our database and this website with this new value.

ValveTrax Tool Width             The default value is 3/4" and will work for 99.999% of all Harmonic Balancers, V-Belt pulleys, Discs and Serpentine pulleys however, if for some reason you want it wider, then simply use the pull-down menu to select the extra width, but note there is an additional fee for larger widths.
