Learn how to fit the Complete crank spare part set in a 1985 Sieger Clou 40 cherry stoner, with clear checkpoints and care tips to keep the mechanism working smoothly.

Quick answer

If the crank on your 1985 Sieger Clou 40 is bent, stripped, or no longer turning the stoner reliably, replace the whole mechanism with the Complete crank spare part set rather than trying to repair individual pieces. Work slowly, keep the small parts contained, and test the crank by hand before you stone fruit again.

Why the complete set is the safer choice for a 1985 model

The Complete crank set is made specifically for the Sieger Clou 40 from 1985. That specificity matters: older kitchen tools often have crank fittings that look similar to newer versions but differ in subtle ways. Buying a generic crank or trying to match a single worn part risks a poor fit and a second repair.

Replacing the whole crank mechanism also removes the guesswork of diagnosing which internal part has failed. If the handle turns but the stoner does not, or the crank wobbles, a complete set gives you a fresh, matched assembly instead of a patchwork of old and new components.

When to replace rather than keep using the old crank

A little play in the handle is normal on a tool this age, but visible cracks, a bent shaft, or a crank that slips under light pressure are signs the part is near the end of its useful life. Continuing to use a damaged crank can put extra strain on the stoner body and make the next repair more involved.

If you are unsure whether the crank or another part is at fault, remove the crank and inspect it on a clean, well-lit surface first. The Complete crank set is a targeted replacement for the crank mechanism itself; it is not a general overhaul kit for every part of the stoner.

How to fit the Complete crank set step by step

Clear a contained workspace: Work over a tray or a light-colored cloth so small pins, washers, or screws cannot roll away. Have the new Complete crank set within reach before you remove anything. Losing a small part mid-repair is the most common reason a simple crank swap turns into a longer job.
Remove the old crank: Detach the existing crank from the Sieger Clou 40 by undoing its retaining screw or pin, supporting the stoner body so it does not tip. Keep the old parts together in the tray; they are useful for comparing orientation with the new set. Checkpoint: if a fastener will not budge, stop and apply a penetrating oil rather than forcing it and damaging the housing.
Match the new set to the old assembly: Lay the Complete crank set beside the old crank and compare the shaft, handle, and mounting points before fitting. The set is made for the 1985 Sieger Clou 40, but confirming the orientation now prevents a reversed fit later. If any part of the new set looks visibly different from the old one, re-check the model year on your stoner before proceeding.
Fit the new crank: Insert the new crank into the stoner in the same orientation as the old one and secure the retaining screw or pin finger-tight first. Do not overtighten; you want the crank to seat fully without compressing the housing. Checkpoint: the crank should sit flush with no gap between the handle assembly and the stoner body.
Test by hand before loading fruit: Turn the crank through several full rotations with the stoner empty. It should move smoothly without wobble, grinding, or catching. If it binds, loosen the retaining fastener slightly and re-seat the crank. Only stone fruit once the empty crank turns freely; this avoids forcing the mechanism under load.
Clean and store for the long term: After use, wipe the crank and stoner with a damp cloth and dry thoroughly before storing. Keep the spare parts tray or bag with the tool so future maintenance is easier. Avoid soaking the crank assembly in water; moisture trapped in the mechanism is a common cause of stiffness.
