On rear final drives (differentials), the pinion shaft and stub axle bearings often require the VAS 6617/2 to provide the necessary counterhold. Without it, a standard two-jaw puller will simply slip off the angled shoulder.
The VAS 6617/2 is the complementary counterpart to the primary T10068A or VAS 6617/1 camshaft lock. Where the primary tool locks the camshafts at TDC for basic timing, VAS 6617/2 is used for fine alignment of the camshaft adjuster (variable valve timing) after timing chain/belt replacement or cylinder head reassembly.
Several reputable brands produce identical tools under license: vas 6617 2
Unlike standard Allen keys or Torx bits, the VAS 6617 2 features a unique design tailored to the "anti-tamper" and space-restricted configurations found in modern VAG headlight assemblies. It is typically constructed from high-grade, hardened steel to withstand the torque required to release tightly fastened adjustment screws that have been subjected to years of engine heat and road vibrations.
Modern VAG transmissions, particularly the newer 7-speed dual-clutch units (e.g., 0CJ, 0CK, 0CL), are highly sensitive to fluid levels. The VAS 6617/2 adapter serves as the physical interface between the VAS 6617 Pressurized Hand Pump and the transmission's fill port. On rear final drives (differentials), the pinion shaft
Typically made from high-strength materials like anodized aluminum or 6-6 Nylon, it provides a lightweight yet robust solution that resists corrosion and wear.
The VAS 6617/2 is engineered to facilitate the clean and efficient filling of transmission fluid into modern gearboxes. Its primary applications include: Where the primary tool locks the camshafts at
Place the VAS 6617/1 bridge over the shaft end. Thread the central pulling spindle through the bridge and into the threaded hole of the VAS 6617/2.
It is not a standalone tool. The VAS 6617/2 is the "business end" that attaches to the main puller bridge (VAS 6617/1) to extract tightly seated ball bearings, needle bearings, and occasionally gears from shafts without damaging the surrounding housing.
If you own a shop specializing in Volkswagen, Audi, Skoda, or Seat vehicles, the VAS 6617/2 is not a luxury—it is a . For the DIY mechanic, consider renting the tool from a specialty VAG tool lending library before attempting a differential bearing replacement. Attempting the job without it will likely end with a trip to the scrap yard or a machine shop.
This article provides an in-depth look at the VAS 6617 2, exploring what it is, why it is necessary, the vehicles it services, and how to use it effectively.
