DP Fit for Life Dual Trac 20 is a classic home gym system. While official digital manuals from the manufacturer (Diversified Products) are rare due to the age of the equipment, the assembly follows a standardized sequence common to most vertical multi-station weight stack machines. Preparation & Required Tools
: Ensure a flat, clear area. Once the weight stack is installed, the machine is extremely heavy and difficult to move. : You will typically need a 9/16" wrench or socket rubber mallet for end caps, and potentially an Allen wrench
: Lay out all carriage bolts, washers, and locknuts. Note that some designs use specific stabilizing plates for the main uprights. Step-by-Step Assembly Sequence Base Frame Assembly
Connect the front and rear base stabilizers to the main bottom center piece.
Use the provided carriage bolts and tighten them securely with your 9/16" wrench.
Tap the plastic end caps into the base tubes using a rubber mallet. Main Upright Post & Weight Rods
Attach the two rear weight plate guide rods to the base frame.
Mount the main vertical support post (the "backbone" of the machine) to the center of the base.
: Only hand-tighten the bolts initially to allow for alignment adjustments later. Weight Stack Installation Slide the weight plates onto the guide rods one by one. Orientation dp dual trac 20 assembly instructions full
: Ensure the pin holes on the plates are facing forward and the selector rod can slide through them easily.
Place the top weight plate (with the selector rod attached) on top of the stack. Top Crossbar & Overhead Pulley
Lift the top crossbar onto the main upright post and the weight guide rods.
Secure the crossbar to the upright using carriage bolts and stabilizing plates.
Ensure the top bar is perfectly horizontal before fully tightening all bolts. Exercise Arm Attachments Butterfly/Press Arms
: Attach the swinging arms to the main upright. These usually require long rods, specific washers, and locknuts.
Ensure there is a small amount of "free play" in the arms to prevent friction or scratching during use.
: Secure the arm and seat pads using the specified shorter bolts and washers. Cable & Pulley Threading
This is the most critical step. Start from the weight stack and thread the cable through the top pulleys, leading it toward the lat bar or press arms.
Ensure the cable sits deep within the pulley grooves to prevent fraying or slipping during heavy lifts. Safety Checklist Check Bolts
: Go back and tighten every bolt once the entire frame is assembled. Lubrication
: Apply a small amount of silicone lubricant to the weight guide rods for smoother movement.
: Perform several light-weight repetitions on each station to ensure the cables are tracking correctly and the machine is stable. scanned PDF copy of the original manual from a vintage equipment archive? Fitness Gear Assembly DIY Step By Step Guide 11 Apr 2021 —
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.
Console Mounting: Install batteries in the monitor and slide it onto the mounting bracket, connecting any sensor wires. Critical Assembly Tips This is the machine's defining feature and the
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.

DP Dual Trac 20 Assembly Guide: Step-by-Step Instructions The DP Dual Trac 20 is a classic, versatile piece of home gym equipment designed to provide a comprehensive strength-training workout. However, unboxing a multi-point cable system can be intimidating. This guide breaks down the assembly process into clear, manageable steps to get your gym up and running safely. Pre-Assembly Checklist
Before you begin, clear a 6' x 8' space for the machine and grab the following tools: Two adjustable wrenches (or a socket set) A Phillips head screwdriver A rubber mallet (optional, for seating end caps)
Pro Tip: Lay out all bolts and nuts by size before starting. This prevents using the wrong hardware in early steps. Step 1: The Main Frame and Base Start by assembling the "skeleton" of the machine.
Base Stabilizers: Attach the front and rear stabilizer bars to the main central base frame. Use the long carriage bolts provided.
Upright Support: Bolt the main vertical upright onto the base frame. Do not tighten these bolts fully yet; leaving them slightly loose helps with alignment in later steps. Step 2: The Seat and Backrest Carriage
Slide the Adjustment Tube: Slide the seat adjustment frame onto the main base.
Attach Pads: Secure the seat and backrest pads to their respective frames using the smaller hex bolts.
Leg Developer: If your model includes the leg extension attachment, bolt the pivot arm to the front of the seat frame now. Step 3: Top Frame and Pulley Brackets
Top Crossmember: Lift the top horizontal frame piece onto the vertical upright. Secure it with the heavy-duty bolts and washers.
Pulley Housing: Attach the fixed pulley brackets to the top frame and the base. Note the orientation: the "open" side of the bracket should face where the cable will enter. Step 4: Cable Routing (The Critical Phase)
The DP Dual Trac 20 uses a dual-cable system. Success here is all about following the path:
High Cable: Start at the lat bar attachment point. Thread the cable over the top pulleys, down through the "floating" pulley block, and back up to the anchor point on the frame.
Low Cable: Start at the leg developer/low row station. Thread it through the base pulleys, up through the underside of the floating pulley block, and anchor it to the rear stabilizer.
Check for Twists: Ensure the cables sit deep in the grooves of the nylon pulleys. If a cable rubs against metal, it will snap prematurely. Step 5: Weight Stack and Final Tensioning
Guide Rods: Insert the weight guide rods into the base. Slide your weight plates on one by one.
Selector Rod: Insert the center selector rod through the plates and attach the cable end to the top of the rod.
Tensioning: Tighten all bolts from Step 1 through Step 3. If the cables feel too loose, adjust the floating pulley bracket position or use the chain links usually provided at the cable ends to take up the slack. Safety & Maintenance
Test without weights: Run the handles through a full range of motion without any weight plates pinned to ensure the cables are tracking correctly.
Lubricate: Use a silicone-based spray on the guide rods for smooth movement. Never use WD-40, as it attracts dust and creates friction.
Check Bolts: Home gyms vibrate during use. Re-tighten all hardware after the first week of training.
