The DP Dual Trac 20 is a classic multi-gym system often remembered for its versatility and space-saving design. Assembling this 1990s staple requires patience, as it features over 40 potential exercises and a complex 70kg variable resistance cable system Essential Prep & Tools
Before starting, ensure you have a clear 69 x 96-inch floor space. You will need: Wrenches/Sockets
: Standard 8mm and larger adjustable wrenches for various bolts. Screwdrivers : A Phillips head for smaller cap screws and covers. Flashlight
: Useful for locating model numbers usually found on the rear main frame near the floor stabilizers. Step-by-Step Assembly Overview Base and Stabilizers
: Begin by placing the floor panel on a flat surface. Attach the floor tubes and stabilizers using the provided carriage bolts and nylon locknuts. Do not fully tighten the nuts until the uprights are in place to ensure everything is square. The Main Uprights
: Secure the left and right upright bases to the long base tube. Use M10 x 90mm bolts and washers as specified. If your model includes a storage tube, attach it to the upright now. Upper Frame & Lat Bar
: Slide the top frame onto the side panels and rear end panel. This section typically supports the lat bar and upper pulley system. Use the hinged screw covers to protect the hardware and your skin from sharp edges. Cable Routing (The Tricky Part)
: This unit uses multiple cable lengths (ranging from 90 to 281 inches). Thread the cables through the pulley wheels, ensuring they sit firmly in the center grooves to prevent binding. For the Dual Trac 20, spring-loaded clips are used to easily swap between rowing bars, curl bars, and the ankle strap. Final Adjustments
: Install the incline bench and butterfly attachment for pectoral development. Check all moving parts—if you feel "binding" or excessive play, you may need to adjust the axle or pulley tension. Maintenance & Parts Fitness Gear Assembly DIY Step By Step Guide
The DP Dual Trac 20 (often listed as Model #15-7000) is a vintage multi-gym system that is generally noted for being relatively straightforward to assemble if you have the original guide. While formal modern reviews are scarce due to its age, users typically highlight the importance of careful cable routing and initial loose-fitting of the frame. Assembly Overview
Based on historical manuals and user guides from platforms like Yumpu and Sears Parts Direct, the process involves these key stages:
Base and Frame Setup: Start by placing the floor panel on a flat surface and inserting the rear and side panels. Use the included hardware (typically 3” cap screws and 2” deck screws) to secure the main frame.
Upright Post Installation: Mount the main upright posts using carriage bolts and stabilizing plates. It is a common tip to hand-tighten only initially to allow for adjustments as you add horizontal bars and the roof/top section.
Moving Parts and Arms: Attach the swinging arm pieces (for butterflies and bench presses) using rods, bolts, and lock nuts. Ensure even spacing on both sides of the main rod to prevent friction and ensure smooth movement.
Cable Routing: This is the most technical phase. The unit allows for over 40 exercises without manual cable changes once set up. Carefully inspect cables for fraying or flat spots before installation. Critical Assembly Tips
Tools Required: You will likely need a Phillips screwdriver, a 9/16 key for carriage bolts, and a rubber mallet to secure the black end caps.
Stability: Ensure the unit is level once fully assembled to reduce wear on bearings and bushings.
Maintenance: Regularly recheck and tighten frame and pivot bolts after the first few workouts, as they may shift during initial use.
For replacement parts like specific cable assemblies, Fitness Repair Parts lists various lengths (e.g., 90-inch or 227-inch) that are compatible with the Fit For Life Dual Trac 20 series.
Once the handlebars are tightened and the chain is tensioned, you stand in front of the machine. You check the gas, turn the key (or kill switch), and kick the starter lever.
If you assembled it right, that 2-stroke will bark to life with a puff of blue smoke and a ringing "ding-ding-ding" of the engine idle. It vibrates. It smells like gas and oil. It’s raw mechanical energy.
The Verdict: Assembling a DP Dual Trac 20 "full" isn't just following instructions. It’s resurrecting a dinosaur. It’s loud, slightly dangerous, and immensely satisfying.
Happy Wrenching.
The DP Dual Trac 20 (often identified by model ) is a classic rowing machine that is frequently found on the used market. Because this machine is no longer in production, users often rely on archived digital manuals and community advice for assembly. Core Assembly Overview
The assembly typically involves five main stages. For those missing the paper manual, digital versions are available through Sears Parts Direct.
Stabiliser Attachment: Connect the front and rear stabilizers to the main frame using the provided carriage bolts and nuts.
Sliding Rail Setup: Insert the seat onto the sliding rail before securing the rail to the main frame. Ensure the seat rollers are correctly aligned with the rail tracks to avoid "jerky" motion later.
Pedal Installation: Attach the pedals to the main frame. Note that some versions require specific bolt positioning (Position A vs. Position B) to ensure the pedals rest at the correct angle.
Resistance Connection: If your model has a tension cable, connect the upper tension wire from the console area to the lower cable coming from the resistance mechanism. dp dual trac 20 assembly instructions full
Console Mounting: Install batteries in the monitor and slide it onto the mounting bracket, connecting any sensor wires. Critical Assembly Tips
Document Cable Routing: If you are reassembling a used unit, take photos of how the cables run through the pulleys. Incorrect routing is the most common cause of "slipping" or "no resistance" symptoms.
Hardware Inspection: Check the condition of the drive belt and bungees before full assembly. Worn or frayed straps should be replaced to prevent slipping.
Proper Leveling: Ensure the unit is placed on a flat surface. An unlevel machine leads to premature bearing and bushing wear, often causing a "thumping" or "squeaking" sound during use. Common Troubleshooting Post-Assembly Likely Cause Jerky Motion Misaligned belt or dirty rail Inspect belt path and clean sliding rail. No Resistance Disconnected tension cable
Re-check the connection between the console cable and resistance unit. Dead Console Battery or sensor wire issue
Verify battery orientation and ensure the sensor plug is fully seated.

The DP Fit for Life Dual Trac 20 (model #15-7000) is a vintage dual-action exercise bike that allows for simultaneous upper and lower body workouts. Because it is an older model, finding a complete original PDF can be difficult, but assembly typically involves four core sections: the base, the main frame/upright, the handlebar system, and the seating/pedal components. Required Tools To assemble this unit, you will typically need:
Wrenches: Standard adjustable wrench or a 9/16" and 1/2" socket set. Screwdrivers: Phillips head.
Allen Wrench: Often included, but a metric set is useful for tightening pivot bolts. Assembly Steps Base and Stabilizers: Lay out the Base Assembly on a flat surface.
Attach the front and rear stabilizer bars to the main base tube using carriage bolts and lock nuts. The front stabilizer often includes wheels for easier transport. Main Frame and Mast: Secure the Main Frame upright to the base.
If your model has an electronic console, feed the tension cable and wire harness through the mast before bolting it down to avoid pinching the wires. Dual-Action Handlebars:
Slide the Handlebar Assembly onto the pivot axle at the top of the main frame.
Ensure the pivot bolts are tightened enough to prevent wobbling but loose enough to allow the "Dual Trac" rowing motion. Check these bolts after your first few workouts. Pedals and Seat:
Pedals: Screw the pedals into the crank arms. Note that the left pedal is reverse-threaded (turn counter-clockwise to tighten).
Seat: Slide the seat post into the frame and secure it with the adjustment knob. Attach the seat cushion to the top of the post using the provided nuts. Console Connection:
Connect the wire plugs from the mast to the back of the console, ensuring they click into place.
Mount the console to the handlebar bracket using the small provided screws. Maintenance Tips
Bolt Check: Periodically re-tighten the frame and pivot bolts to reduce bearing wear.
Cleanliness: Wipe sweat off moving joints and the console area after every use to prevent corrosion.
Leveling: Ensure the unit is on a level surface to prevent uneven wear on the bushings.
If you need specific replacement parts like cables or belts, you can find diagrams and listings on sites like Sears PartsDirect or Fitness Repair Parts. Do you have all the original hardware (bolts/nuts), or Official Lifestyler 15666-DUAL TRACK 20 weight system parts
Visual check: Both cables should move freely without crossing. The pulleys must rotate in the same plane (no diagonal pull).
Pro tip: Before full tension, thread each cable through its pulleys with the carriages removed. Then install carriages over the cables.
Most people assembling a Dual Trac 20 today are doing so from a "basket case"—a bike that was disassembled years ago and left in a barn, or a crate of New Old Stock (NOS) parts.
Before you open any boxes, read these safety rules. Incorrect assembly of a cable pulley system can lead to sudden cable failure or injury.
Objective: Erect the main columns that carry the weight stack and pulley carriage.
Common mistake: Forgetting to insert the plastic guide rod bushings at the bottom of each upright. These bushings hold the weight plate guide rods. Install them now.
