A tool you didn’t know you needed — until you use it once. Designed and tested in a real-world engine building environment, the HRB RB Oil Pump Install Sleeve is a simple yet vital addition to your workshop. We use it every day during assembly, and it’s especially critical when fitting oil pumps onto RB engines that have crank collars installed, where the seal lead-in is extremely minimal.

This tool ensures that the oil pump housing front seal slides smoothly onto the crankshaft without folding, tearing, or misalignment, drastically reducing the risk of costly damage. Precision-engineered for seamless installation, it eliminates the common frustrations and failures often encountered during manual oil pump fitting.

Compatible with all NISSAN RB20DET, RB25DET, and RB26DETT engines.

Key Features:

• Precision machined from billet 6061 aluminium
• Anodised finish for enhanced durability
• Optimised design to protect seals and simplify installation

Why Choose the HRB RB Oil Pump Install Sleeve?

Oil pump installation, especially on engines with crank collars, often leads to folded, torn, or misaligned seals—problems that can cause costly oil leaks later. The HRB Install Sleeve eliminates that risk, helping the pump and seal glide perfectly into place without stress or damage. Whether you’re completing a fresh RB build, refreshing a high-horsepower street car, or assembling a track-only race engine, this tool guarantees a smoother, more reliable installation process.

Ideal for use on performance NISSAN RB engines across street, drift, and racing applications. HRB professional engine building tools are designed to solve real-world workshop challenges with precision, reliability, and efficiency.
