Workshop manual series
1053
Covered with the 1054 in the classic workshop manual set. Type and serial plates identify the exact engine; quote them for any service correspondence. Full manual text is not published here yet.
Workshop manual series
1054
Documented alongside the 1053. Appears in enthusiast records as a heavier multi-cylinder marine option within the same manual family. Treat as heritage reference, not a sales listing.
Earlier lineage
Semi-diesel / hot-bulb
Earlier Bolinder oil-engine tradition (including hot-bulb designs) is distinct from later four-stroke 105x diesels. Keep manuals and restoration advice on the correct lineage when working on a survivor.
