Description
Overview:
This rewind spring is a genuine Hatz spare part (part no. 05045202) for the recoil starter on Hatz single‐cylinder diesel engines, including the 1B20 and 1B30. Formed from durable spring steel in a flat spiral, it stores and releases the energy needed to retract the starter rope cleanly after each pull. Correct spring tension is essential for smooth, dependable starting and for preventing rope slack or snagging inside the starter housing. Purpose‐built for the Hatz 1B series, it offers an accurate, like‐for‐like replacement that helps restore the starter mechanism to factory performance. Suitable for small plant and machinery powered by Hatz engines, it supports quick maintenance turnaround and long service life when fitted and pre‐tensioned correctly.
Key Features:
- Genuine Hatz part for assured fit and compatibility (05045202)
- Precision‐matched to OEM tension and travel for reliable rewind
- Robust spring steel construction designed to resist fatigue and set
- Smooth, even rope retraction helps reduce fray and pawl wear
- Stable pre‐tension supports consistent cold and hot starts
- Flat‐spiral profile fits neatly within the original starter drum
- Straightforward to install with standard hand tools, minimising downtime
- Ideal preventive replacement during routine service or starter rebuilds
Typical Applications:
Used to restore proper rope return and starter function on equipment powered by Hatz 1B series engines, such as plate compactors, generators, water pumps, small mixers, and site lighting units. Commonly fitted during servicing when the starter rope fails to retract fully, tension weakens, or the original spring has fractured or lost its set.
