Pioneer Tarp Pivot Assembly Parts

Replacement pivot assembly parts for Pioneer Tarp systems — pivot bushings, pins, mounting hardware, and complete pivot assemblies. The rotating hardware at the base of the arm assembly.

What this page covers

Pivot assemblies handle the rotational motion of the arm — every tarp deployment and retraction cycle stresses the pivot bushings and pins. Worn pivot bushings cause arm wobble, accelerated tarp wear, and eventually pivot pin shear.

PRT stocks pivot bushings, pins, and complete pivot assemblies for Pioneer Tarp installations.

How to choose

Match by Pioneer Tarp model and pivot pin diameter.

Replace bushings and pins together — worn bushings damage new pins quickly.

Pivot assembly options

  • Pivot bushingsBrass and polymer bushings.
  • Pivot pinsHardened steel pins.
  • Mounting bracketsPivot-side and frame-side hardware.
  • Complete pivot assembliesFull pivot with bushing, pin, and mounting.
  • Grease fittingsFor periodic pivot maintenance.
  • Replacement sealsFor sealed-bearing pivot designs.

Frequently asked questions

How do I know if my Pioneer Tarp pivot needs replacement?

Visible arm wobble or play at the pivot point. Excessive grease leakage. Pivot pin elongation visible on inspection.

Are Pioneer Tarp pivot bushings made of brass or polymer?

PRT stocks both. Brass bushings for heavy-duty applications; polymer bushings for lower-load applications and quieter operation.

Should I replace pivot pins and bushings together?

Yes. Worn bushings have ovalled the bore and the pivot pin has matching wear — using a new pin in a worn bushing fails quickly.

How often should I grease Pioneer Tarp pivots?

Monthly in standard service; weekly in high-cycle applications. Use a light hand — over-greasing can damage seals.
