To find the correct spare part for your Harken winch, identify your winch's exact series and size (for example, Radial 46 or Performa 46.2), then open that model's page on MAURIPRO Sailing and use its labeled exploded-view diagram to click straight through to the individual part you need. The series and size stamped on your winch are the two facts that determine which pawls, springs, jaws, stripper arms, and bearings will actually fit.
Harken spare-part lookup at a glance
| Step | What to do | Why it matters |
|---|---|---|
| 1. Identify series | Read the model name on the winch drum or base (Radial, Performa, Unipower, Rewind). | Each series has its own parts family. |
| 2. Identify size | Note the size number (e.g., 15, 46, 50, 80). | Parts differ by drum size even within a series. |
| 3. Open the model page | Filter Winches by Harken and select your exact model. | The page carries the correct exploded view. |
| 4. Use the exploded view | Click the labeled part in the diagram. | Links go directly to the matching spare. |
How do I identify my Harken winch series and size?
Harken self-tailing winches are grouped into families — Radial, Performa, Unipower, and Rewind — and each is offered in a range of sizes such as 15, 20, 46, 50, 60, and 80. The series name and size number are the two identifiers that drive every spare-part decision, because a jaw assembly or stripper arm made for a Radial 46 will not fit a Radial 50 or a Performa of the same size. Check the drum, the base casting, or your original invoice to confirm both before ordering.
How do I find the exact spare part on MAURIPRO Sailing?
Start in the Sailing Equipment section and open the Winches category, then filter by the Harken brand so only Harken winches and their related parts appear. Browse to your specific model — paying attention to the series name and size (for example, Performa 46.2) — and open its dedicated page. Each model page carries detailed specifications and compatibility notes, an exploded-view diagram with every part labeled, and interactive links on that diagram so you can jump straight to the individual spare you need and add it to your cart.
Which Harken winch parts wear out most often?
The parts that need replacing most frequently are the internal wear items: pawls and pawl springs, roller bearings, and the stripper arm and peeler that guide the line off a self-tailing drum. These see the most cyclic load and are the usual reason a winch skips, drags, or fails to self-tail cleanly. Jaw assemblies and stripper-arm supports are replaced less often but are equally size-specific, so match them to your exact model.
What if I can't identify my winch model?
If the series or size has worn off, compare your winch to Harken's current and legacy model images, or send us a photo of the drum, base, and any visible casting numbers and our rigging team will identify it for you. Never order by eye alone — a part that looks similar but comes from a different size or series often will not seat correctly.
Frequently asked questions
How do I know which Harken winch series I have?
Look for the series name — Radial, Performa, Unipower, or Rewind — on the drum, base casting, or your original purchase invoice. The series plus the size number together identify your winch.
Are Harken winch spare parts interchangeable between sizes?
Generally no. Most parts are specific to a series and size; a Radial 46 jaw assembly will not fit a Radial 50. Some wear items like the B038 pawl spring do span a range (Radial and Performa sizes 15 to 80).
What is the exploded view on the product page?
It is a labeled diagram of the winch showing every component. On MAURIPRO model pages the labeled parts are clickable, taking you directly to the matching spare part for purchase.
Which Harken winch parts fail most often?
Pawls, pawl springs, roller bearings, and the stripper arm or peeler are the most common replacements because they carry the most repeated load during use.
Can MAURIPRO help me identify my winch and part?
Yes. Send a photo of the drum, base, and any casting numbers to our rigging team and we will confirm the correct series, size, and spare part before you order.
