Titan 180-972 Conrod Extension
Hydra part 180-972 is a conrod extension used in the fluid pump drive system of Hydra M and Hydra Pro Super airless sprayers. This extension connects the connecting rod to the piston assembly, translating rotary motion from the drive into linear pumping action. Replacing a worn, cracked, or damaged conrod extension restores proper pump stroke and prevents drive‑train misalignment.

Connecting Rod Extension for Hydra M & Hydra Pro Super
The Hydra 180-972 conrod extension is a precision‑machined component that forms part of the reciprocating drive assembly in Hydra M and Hydra Pro Super airless paint sprayers. It attaches between the main connecting rod and the piston assembly, converting rotational motion from the motor and gearbox into linear stroke for the fluid pump.
This extension is subject to high cyclic loads during operation. Wear, fatigue cracking, or damage can lead to reduced pump output, unusual noise, or complete loss of pumping action. Replacing a compromised conrod extension with an OEM‑spec part restores correct geometry, smooth operation, and reliable pressure delivery.
What it does and when to replace it
| Drive transmission | Transfers motion from connecting rod to piston assembly |
|---|---|
| Stroke length | Maintains correct piston stroke for proper fluid displacement |
| Load bearing | Withstands high compressive and tensile forces during operation |
| Visible damage | Cracks, bending, corrosion, or elongation of mounting holes |
|---|---|
| Loss of pump output | Reduced flow or inability to build pressure despite motor running |
| Unusual noise | Knocking, clunking, or grinding sounds from drive area |
| Excessive play | Noticeable slack between connecting rod and piston assembly |
