Automotive measuring tool for verifying bearing clearances, introduced as Powerbuilt Plastic Gauge. Engine builders and mechanics gain confidence during assembly with a simple torque-and-compare checking method. Is this a workshop staple worth adding to routine rebuild checks?
⚡ At a Glance
- • Measurement Range: Includes green tape (.001" - .003") and red tape (.002" - .006")
- • Best for: Engine builders and mechanics verifying oil clearance
- • Not ideal for: Situations requiring digital readouts or sub-micron micrometre precision
Dual colour-coded tape strips cover very small oil clearances. Torque the assembly to spec and compare the tape width to the printed scale for a clearance reading.
Accurate bearing clearance checks - with dual-range tape strips
Colour-coded plastic strips capture the maximum clearance width when placed between bearing and journal and the assembly is torqued to specification. Two tape ranges cover small oil clearances, allowing direct comparison against a printed scale.
Provides repeatable clearance readings without complex measuring instruments. Results help confirm correct oil clearance during engine assembly.
Faster, repeatable workflow - thanks to the torque-and-compare method
A strip is positioned between bearing and journal, the part is torqued to spec, and the strip is removed and measured against the scale. The simple sequence reduces steps compared with multiple micrometre measurements.
Speeds up checks during rebuilds, letting technicians complete clearances in minutes. Repeatable method reduces the chance of assembly errors.
