1. Introduction
Thank you for choosing the WishiLOT 174PCS MOC Pin Set. This set provides a comprehensive collection of technical pins, pegs, and bushes designed to enhance your building block creations. These components are essential for creating robust connections, intricate mechanisms, and flexible structures in your MOC (My Own Creation) projects. This manual will guide you through the components, their applications, and general care.
2. Package Contents
Your WishiLOT 174PCS MOC Pin Set includes a variety of pins, pegs, and bushes. The exact assortment is designed to offer versatility for numerous building applications.

The set typically includes:
- Various lengths and types of connector pins (e.g., friction pins, axle pins)
- Bushes for spacing and friction control
- Specialized tech connectors for unique structural needs
The components are provided in assorted colors (e.g., black, grey, light grey, red, blue, tan) to match common building block systems.
3. Setup and Usage
This pin set is designed for integration with standard building block systems. No assembly of the pins themselves is required; they are ready for immediate use in your construction projects.
3.1. Identifying Components
Familiarize yourself with the different types of pins and bushes. Refer to Figure 1 for a visual guide to the variety included in your set. Common types include:
- Friction Pins: Provide a tight, secure connection.
- Axle Pins: Allow for rotation and movement.
- Bushes: Used to reduce friction, act as spacers, or secure axles.

3.2. Integration with Building Blocks
Insert the pins into the appropriate holes on your building blocks or other technical elements. Ensure a snug fit for stable connections. For moving parts, select axle pins and bushes to allow for smooth rotation.
4. Operating Principles
The pins and bushes function as connectors and structural elements within your building block models. Their primary purpose is to join pieces together, create pivot points, or provide structural reinforcement.
4.1. Creating Connections
Use pins to connect two or more building block elements. The length and type of pin will depend on the depth of the connection and whether a tight or loose fit is desired.
4.2. Articulation and Movement
For parts that need to rotate or pivot, use axle pins in conjunction with bushes. The bushes help to reduce friction and ensure smooth movement, which is crucial for functional models like vehicles or robotic arms.

5. Care and Maintenance
To ensure the longevity and optimal performance of your MOC Pin Set, follow these simple care instructions:
- Cleaning: Clean the pins and bushes with a soft cloth dampened with mild soap and water. Avoid harsh chemicals or abrasive materials.
- Drying: Ensure all components are thoroughly dry before storage or reuse to prevent water spots or residue buildup.
- Storage: Store the pins and bushes in a dry, cool place, away from direct sunlight. Using a compartmentalized storage box can help keep different types organized and prevent loss.
- Handling: Avoid excessive force when inserting or removing pins to prevent damage to the components or your building blocks.
6. Troubleshooting
Most issues with building block pins are related to incorrect usage or component selection.
6.1. Loose Connections
- Cause: Using a pin type not suited for a tight friction fit, or worn-out components.
- Solution: Ensure you are using friction pins for static connections. If components are old, they may have lost some of their grip; consider replacing them.
6.2. Stiff or Non-Rotating Parts
- Cause: Incorrect pin type used for articulation, or lack of bushes.
- Solution: Use axle pins for rotating parts. Ensure bushes are correctly placed to provide spacing and reduce friction between rotating elements.
6.3. Difficulty Inserting Pins
- Cause: Misalignment or excessive friction.
- Solution: Align the pin carefully with the hole. Apply gentle, even pressure. Do not force pins, as this can damage the blocks or the pins themselves.
