This set is used to re-cut and clean diesel injector seats. It ensures the seat is perfectly flat and to the correct dimensions, allowing new or reconditioned injectors to seal properly and prevent engine blow-back.
While some users might attempt it, the manufacturer strongly recommends removing the cylinder head. This is crucial to prevent metal filings and debris from entering the combustion chamber, which can cause severe engine damage.
You should identify the exact dimensions of your vehicle's injector seat. Referencing your vehicle's service manual is the best way to determine the correct size. The set includes various common sizes ranging from 14mm to 19mm.
The cutters are manufactured from SKD11 steel, a high-quality material known for its durability and cutting performance.
The set includes the tools and a storage case. Specific usage instructions depend on the vehicle make and model. It is recommended to consult a professional workshop manual for detailed procedures.
After use, clean all components thoroughly with a degreaser, dry them completely, and apply a light coat of oil to prevent rust. Store them securely in the provided blow-molded case.
Blow-back refers to exhaust gases leaking past the injector seal into the intake manifold or combustion chamber due to a poorly seated injector. This tool helps prevent blow-back by ensuring a proper seal.
Ensure you are using the correct size and type of reamer for the injector seat. Check if the reamer's cutting edges are clean and sharp. Apply steady, moderate pressure; do not force the tool.
Confirm that you are attempting to insert the correct pilot bit or reamer size. The pilot should guide the reamer smoothly. Verify that there are no obstructions or severe damage in the bore.
This indicates improper use. The cylinder head should have been removed prior to using the tool. Thoroughly clean the cylinder head and piston before reassembly. This situation highlights the critical importance of following the "cylinder head removed" recommendation.
Ensure the reamer or pilot bit is fully and securely inserted into the T-handle socket. Check for any damage to the socket or the tool's shank.

The set includes common sizes like 14mm, 15mm, 15.5mm, 17mm, 17.5mm, and 19mm, in both flat and angled profiles, catering to many European, Asian, and American diesel engines.
