ValveTrax®

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

Designs

There are two different ValveTrax designs; a Centerline design and a Mid-Point design.

The Centerline design is for the meticulous engine builder that wants to adjust each valve individually and therefore, shows colored graphics for the rotational location of each intake and exhaust valve to be adjusted.  An example of a ValveTrax Centerline tool for an 18-cylinder engine is shown below:

The Mid-Point design is for the engine builder that wants to adjust both intake and exhaust valves simultaneously to save time and therefore, shows colored graphics for the rotational location of the calculated “Mid-Point” between each intake and exhaust valve so both intake and exhaust valves can be adjusted concurrently.  An example of a ValveTrax Mid-Point tool for an 18-cylinder engine is shown below:

Here are three Mid-Point examples below that show a 6-cylinder engine with;

A. No crankshaft offset (0°),

B. a -22° crankshaft offset (Advanced),

C. a +22° crankshaft offset (Retarded):

The Mid-Point example below shows a 14-cylinder engine ValveTrax tool that could be installed on the propeller shaft Disc of an aircraft engine with a Reduction Ratio of 1.5:1 and rotates in the CCW direction (note the horizontal arrows pointing towards the left):

The two Mid-Point examples below shows a 14-cylinder and a 9-cylinder engine ValveTrax tool that could be installed on a propeller shaft Disc of an aircraft engine with a Reduction Ratio of .5:1 and rotating in the CCW direction.  The different colors represent the number of manual revolutions needed (4) to adjust all the valve lashes where the Disc is rotating twice as fast as the crankshaft:

Near the bottom of the tool shows a "Tolerance Bar" at each cylinder location anywhere you want your engine pointer to be at.  All of my ValveTrax designs have a range of selection for the #1 Intake Centerline and the Lobe Separation Angle within the ranges shown below.  The common range of these values are as follows and can be selected on the Ordering Page:

     #1 Intake Centerline;  100 - 120 degrees

Lobe Separation Angle;  106 - 118 degrees

As a final note, using the ValveTrax Centerline tool on a Chevy V8 engine with a roller camshaft and hydraulic lifters to adjust all the valve lashes takes about 10 minutes.  Using the ValveTrax Mid-Point tool only takes about 7 minutes!
