Bergmann
Bergmann tracked dumpers by model on PartsForMachines: the 4010 and the 4010HK, listed in the Machinery Parts Finder with track adjusters and rubber tracks matched to each and the price on every listing. A dumper with slack tracks and an adjuster that will not hold pressure is what brings a Bergmann owner here, and both parts are listed against the model.
Bergmann track adjusters and tracks: 4010, 4010HK
Track adjusters and rubber tracks are listed against the Bergmann model with width, pitch and link count on the listing. The HK takes a longer track than the standard 4010, and the link count on the listing is the check.
The Machinery Parts Finder is the route: Bergmann, 4010 or 4010HK from the dropdown, then adjuster or track. A part number goes into the header search. Skip-side plate worn, photo to 07754288583 on WhatsApp. The Compatible tab confirms the fit.
Track-tensioning kit and hydraulic oil through the Oil Finder head the wider range, then batteries, filters and the rest by specification. Not in the Finder? Ask Simon.
