Exercise Variety: Supports over 40 different exercises without requiring cable changes, including lat pull-downs, rowing, and leg lifts. Finding Replacement Manuals and Parts
Because DP (Diversified Products) is no longer in business, original PDFs are often hosted on enthusiast archives or secondary parts sites:
Manual Repositories: Sites like Yumpu sometimes host legacy assembly guides for the DP-20 series.
Spare Parts: If you are missing specific hardware or cables, FitnessRepairParts.com and Sears Parts Direct list compatible cable assemblies and diagram references for models like the 15-7000 or 15666.
Whether you’ve just hauled a vintage DP Dual Trac 20 out of storage or picked one up at a garage sale, getting it properly assembled is the first step toward a solid home workout. Known for its sturdy frame and dual-action rowing and stepping motion, this classic piece of equipment is a staple of durable home fitness.
Since original printed manuals for these machines are increasingly rare, this guide serves as a comprehensive assembly walkthrough and digital reference for the DP Dual Trac 20. Pre-Assembly Checklist
Before you begin, clear a flat workspace of at least 6' x 4'. Lay out all components to ensure nothing is missing: Main Frame: The long central rail. Front Crossbar: The stabilizer with end caps. Handlebars: The "Dual Trac" arms that provide resistance.
Seat Assembly: The padded seat and the rollers that attach it to the frame. Resistance Cylinders: The hydraulic shocks (usually two).
Hardware Kit: Various bolts, washers, and nylon locking nuts. Required Tools: Two adjustable wrenches (or a socket set). A Phillips head screwdriver.
A small amount of lithium grease or WD-40 (for the seat rollers). Step-By-Step Assembly Instructions 1. Stabilize the Base
Flip the main frame upside down. Align the front stabilizer crossbar with the bracket at the front of the frame. Insert the carriage bolts from the bottom up, secure them with washers and nuts, and tighten until the frame no longer wobbles. Flip the unit back over to its upright position. 2. Install the Sliding Seat Slide the seat carriage onto the main rail. Before starting any assembly, you must obtain the
Pro Tip: Apply a thin layer of lubricant to the rail before sliding the seat on. This ensures a smooth, quiet glide and prevents the rollers from wearing down prematurely.
Once the seat is on, bolt the rear end-cap or stopper onto the back of the rail to prevent the seat from sliding off during use. 3. Attach the Dual-Action Handlebars
Locate the pivot points on the sides of the main frame. Align the handlebar arms with these pivots. Insert the long pivot bolt through the frame and the arm.
Note: Do not over-tighten these bolts. The arms need to move freely. Use the nylon locking nuts to ensure the bolt stays secure without being clamped too tight. 4. Connect the Hydraulic Resistance
This is the most critical step for the Dual Trac 20’s functionality.
Connect the base of each hydraulic cylinder to the main frame using the provided pins or bolts.
Connect the top of the cylinder to the bracket on the handlebar arms.
Most models feature multiple "holes" on the handlebar bracket; moving the cylinder to a hole further from the pivot point will increase the resistance level. 5. Final Safety Check
Check every bolt and nut. Ensure the foot pedals are bolted tightly to the frame and that the straps are intact. Test the range of motion by moving the handlebars and seat slowly to ensure there is no grinding or clicking. Maintenance Tips for the DP Dual Trac 20
To keep your machine running like new, follow these simple maintenance steps:
Wipe Down the Rail: After every workout, wipe the central rail with a dry cloth to remove sweat and dust, which can cause the seat rollers to "flat-spot."
Check the Shocks: Hydraulic cylinders can leak over time or lose resistance if they get too hot. If you notice a loss of tension, the cylinders may need to be replaced.
Tighten Hardware: Heavy use can vibrate nuts loose. Give the machine a "tune-up" once a month by tightening all primary connections. Finding the "Manual PDF"
While Diversified Products (DP) is no longer in business, many users look for the original DP Dual Trac 20 Manual PDF for specific exploded parts diagrams. If you require the original schematics, fitness equipment archive sites often host scanned copies of these legacy manuals. Look for "Vintage DP Fitness Manuals" in PDF repositories or community forums dedicated to home gym repair.
The DP Dual Trac 20 is a classic home multi-gym that was a staple of many 90s home gyms. If you've just picked one up secondhand or moved it out of storage, putting it back together can feel like a massive puzzle.
Below is a guide to getting your Dual Trac 20 fully functional, including where to find that elusive manual and tips for a safe assembly. 🛠️ Assembly Prerequisites Before you start turning bolts, gather these essentials:
Space: You need an area of at least 69 x 96 x 38 inches for the full unit.
Tools: A socket set (especially a 9/16 key or wrench), an Allen wrench set, and a rubber mallet.
Surface: Assemble on a flat surface. Using rubber flooring or a gym mat underneath is highly recommended to protect your floor and stabilize the machine. 🏗️ Step-by-Step Assembly Guide
While the original PDF can be hard to track down, the assembly flow for DP (Diversified Products) units generally follows this sequence:
The Base Frame: Lay out the bottom stabilizers and attach the main floor frame. Do not fully tighten these bolts until the uprights are in place.
Weight Stack Uprights: Slide the two main vertical poles through the bottom piece. These will eventually hold your weights.
Weight Plates: Slide the weight plates onto the rods. Crucial: Ensure the pin holes are facing forward so you can actually change the weight once it's built.
The Main Post & Top Bar: Install the vertical main post and the top horizontal bar. This "cages" the weight stack and provides the mounting point for the pulleys. ⚠️ Warning: Be careful with third-party PDF sites
Pulleys & Cables: Thread the cables through the pulleys. This is the trickiest part—ensure the cables sit deep in the pulley grooves to prevent fraying.
Attachments: Connect your "butterfly" arms, bench press bar, and lat pull-down bar using the provided pins and spring-loaded clips. Where to Find the Manual PDF
Since DP is no longer in production, you’ll need to rely on archives:
Sears PartsDirect: Search for model #15-7000. They host diagrams and parts lists that are often more helpful than a text-only manual.
Fitness Repair Parts: You can find specific cable assembly diagrams and pulley guides here.
Manualslib / Yumpu: These sites often have user-uploaded versions of "DP Trac 20" or "Dual Trac 20" instructions. ⚠️ Safety Checklist
Inspect Cables: Look for fraying or cracking in the plastic coating; if you see wire, replace it immediately.
Bolt Check: After your first few workouts, re-tighten every bolt. Vibration can loosen them during the "settling" phase.
Lubrication: Apply a small amount of silicone lubricant to the weight stack guide rods for smooth movement.
💡 Pro Tip: If you're missing a specific bolt, take an existing one to a local hardware store. These machines typically use standard Grade 5 hardware that is easy to replace.
