JVAN CNC Airsoft Gear Set 100:200 New Tappet Plate Pin Position

The JVAN 100:200 airsoft gear set combines a CNC-machined sector gear, spur gear and a bevel assembly for Version 2 and Version 3 gearbox builds. Its defining JVAN design feature is the new tappet plate pin position, supported by the current through-hole, 15-degree chamfer and tooth-profile updates published for this configuration.

The 100:200 marking identifies this specific JVAN gear-set configuration; it is not a percentage or a guaranteed speed, torque or rate-of-fire result. Choose it only when the build calls for the 100:200 configuration, then verify the complete gearbox, piston, tappet plate, axle support and shimming plan before powered testing.

Key Decision Specifications

• Configuration: 100:200
• Listed gearbox application: Version 2 or Version 3 airsoft gearbox
• Sector and spur gear material: 42CrMo/SCM440 steel, CNC machined
• Bevel assembly: MIM bevel gear with a CNC-machined 42CrMo/SCM440 center shaft gear
• JVAN design feature: new tappet plate pin position
• Recommended battery voltage: 11.1V
• Pack options: 1x, 4x, 8x or 12x complete gear sets

What JVAN Changed

• The previous 5mm sector-gear holes were changed to through-holes.
• The sector-gear chamfer was changed to 15 degrees.
• The new tappet plate pin position is the current official design feature. JVAN’s published product description states that this position delays tappet plate release for high-speed operation.
• Customized hobbing tools are used to refine the tooth profile and its mesh with the piston rack.
• The bevel shaft uses a customized tooth shape and increased tooth width. JVAN’s current published description presents this change as supporting greater torque resistance.

These points describe the current 100:200 design. They do not establish a universal gearbox fit, maximum ROF, motor or spring limit, or a guaranteed finished-build result.

Sector Gear

The sector gear is made from 42CrMo/SCM440. The current design uses through-holes, a 15-degree chamfer, the new tappet plate pin position and customized hobbing tools. The published manufacturing sequence includes CNC turning, CNC hobbing, CNC milling, heat treatment, polishing and blackening.

Spur Gear

The 42CrMo/SCM440 spur gear is produced through CNC turning, CNC hobbing, heat treatment, polishing and blackening. JVAN’s current published description states that integrated turn-and-mill machining is used to improve precision and control swing, supporting smoother high-speed operation and lower noise.

The detailed spur-gear section lists HRC42–47 for the current version and HRC33–38 for the previous version. The same published description states that the blackening process adds almost no measurable surface-layer thickness, helping avoid a dry-feeling coating between the meshing surfaces.

Bevel Gear and Shaft

The bevel assembly combines an MIM bevel gear plate with a separately produced CNC-machined 42CrMo/SCM440 shaft. Both sides of the bevel gear and its inner bore are precision machined to reduce swing associated with lower-precision MIM surfaces.

The shaft is produced through CNC turning, CNC hobbing and straight-grain rolling. Its customized tooth shape and increased tooth width are described on the current product page as improving torque resistance. The detailed published hardness values are HRC42–47 for the bevel gear and HRC48–52 for the gear shaft.

Who This 100:200 Gear Set Is For

Choose this product when the build documentation or technician calls for the JVAN 100:200 configuration with the new tappet plate pin position. It is intended for builders who can verify gearbox clearance, axle support, piston-rack engagement, tappet timing and gear mesh before powered testing.

If you are still choosing between JVAN configurations or conventional AEG gear ratios, do not decide from the numbers alone. Compare JVAN airsoft gear sets and read the airsoft gear ratio guide before ordering.

What to Check Before You Order

• Confirm that the build calls for the 100:200 configuration.
• Confirm Version 2 or Version 3 gearbox-shell clearance and axle seating.
• Check bushing or bearing size, alignment and support.
• Check piston-rack pickup and engagement through the complete cycle.
• Check tappet plate release and nozzle timing with the new tappet plate pin position.
• Set shimming, lubrication and gear mesh before powered testing.
• Treat the published 11.1V recommendation as one build input, not as a universal motor, spring or performance limit.

What’s Included

• 1 × sector gear per set
• 1 × spur gear per set
• 1 × bevel gear per set

Select 1x, 4x, 8x or 12x from the product options. The multiplier is the number of complete three-gear sets ordered. Current product imagery also shows the JVAN logo and packaging presentation; match the selected pack quantity to the option shown at checkout.

100:200 vs Other Gear Set Options

100:200 vs JVAN 100:300

These are separate JVAN product configurations. This page documents the 100:200 set and its new tappet plate pin position. Do not infer speed, torque, timing or compatibility differences from the numbers alone; choose the configuration specified for the intended build.

100:200 vs Conventional AEG Gear Ratios

A conventional 12:1, 13:1, 16:1 or 18:1 set follows a different product specification. Compare the full gear configuration, gearbox fit, piston engagement, tappet timing and supporting components instead of treating one label as universally better.

Buyer Questions

What does 100:200 mean on this gear set?

100:200 is the gear-ratio designation for this JVAN gear set. It identifies the gear transmission ratio.

What design changes are listed for this 100:200 gear set?

JVAN identifies the New Tappet Plate Pin Position as the official design term for this version. The published product information also lists through-holes, a 15-degree sector-gear chamfer and customized tooth-profile work.

Will this 100:200 gear set fit every V2 or V3 gearbox?

No. The product is listed for Version 2 and Version 3 airsoft gearboxes, but final fit depends on the specific gearbox shell, bushings or bearings, axle seating, piston rack, tappet plate, shimming and complete component combination.

What should I check before installing the gear set?

Verify gearbox-shell clearance, axle seating, gear mesh, piston pickup and engagement, tappet release and nozzle timing, shimming, lubrication and free movement before powered testing.

Which pack options are available?

The product page offers 1x, 4x, 8x and 12x pack options. Confirm the selected pack quantity and current availability at checkout.

Can I substitute the 100:200 gear set for the 100:300 version?

Do not treat the two gear ratios as interchangeable based on the numbers alone. Use the gear ratio specified by the build documentation or technician. JVAN has not published a universal speed, torque or compatibility comparison between them.

Confirm the Gear Ratio, Then Select a Pack

Choose 1x, 4x, 8x or 12x, then confirm that the 100:200 gear ratio matches the intended build. Check the gearbox shell, piston, tappet plate, axle support and shimming plan before adding the product to your cart. For design background, read the JVAN sector-gear timing article.
