Laser Tools Stubby Star Socket Bit - T60 x 1/2"D

Its primary application is for relieving the tension on V-belts fitted to 6-cylinder common rail TDI engines, notably on the Audi A6, where it serves as an equivalent to OEM tool T40087.

Stubby refers to the tool's short length (45mm). This compact design is beneficial for working in confined spaces within an engine bay where a standard-length socket might not fit.

It has a 1/2" square drive, making it compatible with standard 1/2" drive ratchets, breaker bars, and torque wrenches.

No, this is a specialized tool. While it has a 1/2" drive, its T60 star shape is intended for specific applications like the V-belt tensioning system mentioned. It is not a general-purpose socket.

It also functions as a 22mm hex bit, offering some limited additional utility.

Clean the bit with a dry cloth after use and store it in a dry environment to prevent rust. Inspect for wear regularly.

MPN stands for Manufacturer Part Number. 7234 is the specific part number assigned by Laser Tools to this Stubby Star Socket Bit.

Verify that the fastener is indeed a T60 Torx type and not a different size or type of fastener. Ensure the bit is fully seated in the drive tool.

Check that the bit is fully inserted into the 1/2" drive of the ratchet. Inspect both the bit's drive socket and the ratchet's square drive for any damage or debris that might prevent a secure connection.

Ensure you are applying force in the correct direction to release the tensioner. Double-check that you have the correct T60 bit size and that it is fully engaged with the tensioner pulley's star recess. If the fastener is seized, consider using a penetrating lubricant (allow time to soak) and a longer breaker bar for controlled force.
