How much weight is on a Weider Pro 6900?
The Weider Pro 6900 weight system (model 831149220) uses a 10-plate weight stack; the manual lists 10 weights in the stack, and the station resistance you feel varies by pulley routing and cable friction. For the exact setup and resistance chart, use the 831149220 owner's manual.
What “weight on it” can mean
Different people use this question to mean different things:
- Weight stack plates included (the physical plates on the machine)
- Maximum resistance at a station (what you feel at the handles)
- User weight limit (maximum body weight for safe use)
- Total machine weight (shipping/assembled weight)
What the manual confirms for model 831149220
Here is what we can state directly from the documentation:
| Spec | What it is | What we know for 831149220 |
|---|---|---|
| Weight stack count | Number of plates in the stack | 10 weights listed in the parts list |
| Resistance at stations | “Felt” load at press arm, butterfly, high pulley, low pulley, leg lever | Varies by station; chart in the manual shows different resistances |
| User weight limit | Maximum user body weight | 300 lb max user weight |
Why the resistance can be higher than the stack
Even with a fixed stack, the resistance at the press arm, butterfly arms, high pulley, low pulley, and leg lever can change because:
- Pulleys create different mechanical advantage by station
- Cable routing changes leverage
- Friction at cables, pulleys, and weight guides affects “felt” resistance
- Left and right arms can feel slightly different
- Worn pulleys or dry guide rods can increase drag
If the movement feels rough or inconsistent, inspect common wear items such as the weight system cable pulley 214226 and cable condition.
Why it matters
Knowing whether you mean stack weight or station resistance helps you choose the right replacement parts (cables, pulleys, selector components) and set realistic training loads for the Weider Pro 6900.

What are the weight increments on a cable machine?
On the Weider PRO 6900 weight system model 831149220, weight changes are made by moving the weight pin to a different plate in the weight stack; the exact plate increment depends on the stack design, and the actual resistance at each station can differ from the selected weight because of the cable and pulley routing (use the chart in the 831149220 owner's manual).
Typical weight increments you’ll see on selectorized cable machines
Most home cable machines use one of these plate patterns:
- 5 lb plates (common for finer progression)
- 10 lb plates (very common)
- 10 lb plates with a smaller “top plate” (lets you make smaller jumps)
- Occasional larger jumps (15 lb or 20 lb) on some stacks
Why the number on the stack may not match what you feel
Your 831149220 uses cables and pulleys, so the resistance at a given station can be higher or lower than the plate you select.
- Pulley “mechanical advantage” can reduce felt resistance at some stations
- Cable routing can change resistance between high, low, and press stations
- Slack or cable stretch can delay when resistance is felt
- Twisted or misrouted cables can cause binding and inconsistent load
Quick check: “selected weight” vs “felt resistance”
| What you’re looking at | What it means | What to use for accuracy |
|---|---|---|
| Weight pin setting | Which plate is engaged | Resistance chart in the manual |
| Resistance at a station | What you actually lift | Compare stations using the chart |
If weight changes feel uneven or “off”
We recommend these basics before replacing parts:
- Confirm the weight pin is fully inserted and oriented correctly (bent end touching the stack, then turned down)
- Inspect cable routing against the cable diagram in the manual
- Check for slack; tighten cables per the manual’s maintenance steps
- Replace worn pulleys if they wobble, bind, or squeal (example: weight system cable pulley 214226)
- Replace a frayed or stretched cable if strands are visible (example: weight system cable 302110)
Why it matters
Using the correct increment and the correct resistance value helps you progress safely, track workouts accurately, and avoid cable or pulley damage from misrouting or overtightening.

How do I find the model number on my 831149220?
Your Weider weight system’s model number is printed on the serial number decal located under the seat. On this unit, the model is shown as 831.14922.0 in the documentation, which corresponds to model 831149220 used for parts lookup. See the 831149220 owner's manual for the exact decal location.
Where to look on the machine
Check these common spots first (starting with the correct one for this model):
- Under the seat: look for the serial number decal
- On the main frame near the seat tube or upright
- Near the weight stack shroud (left or right side)
- On the back of the base or stabilizer tube
What to write down (and why)
Record both identifiers from the decal so you can match diagrams and order the right parts.
- Model number
- Serial number
- Brand (Weider)
- Product type (Pro 6900 weight system)
Model number format you may see
| Where you’re looking | How it may appear | What to use for parts |
|---|---|---|
| On the decal/manual | 831.14922.0 | 831149220 |
Why it matters
We use the model number to match the correct parts list and exploded drawings. That prevents ordering the wrong cable, pulley, or hardware when you are replacing wear items like a weight system cable pulley 214226 or a weight system cable 302110.
