An owner rebuilding a basket-case Craftsman LT1000 from a moved-out neighbor was missing the deck’s brake spring arm, part 165890 (Husqvarna’s catalog calls it “Arm Spring Brake Mower,” meaning the arm the blade-brake spring hooks to, not a spring), and on My Tractor Forum his one eBay order sat unshipped for a week from a seller with a history of delays. The fix is to widen the search using the same part’s other identity. Craftsman 165890 is AYP/Husqvarna 532165890, and once you know the 532-prefix cross-walk you can buy the identical part from a vendor who actually ships. There is now a third number to know as well: Husqvarna has superseded 532165890 to 529845801, and the freshest dealer stock sits under that one.
Summary
Craftsman, AYP, and Husqvarna are the same parts ecosystem, and the universal cross is the 532 prefix: a Craftsman six-digit number like 165890 is the AYP/Husqvarna 532165890 (the 532 prefix plus the same six digits). Husqvarna has since superseded 532165890 to 529845801, listed as the same arm with the same UPC, so the current genuine part usually sits under the new number. The part is the stamped-steel arm the blade-brake spring hooks to, not the spring itself, which has its own number on the deck diagram. Knowing this lets you search all three numbers and buy from whoever has stock and ships reliably. For this specific part, an authorized Husqvarna dealer or a dedicated parts site like PartsTree, Jack’s Small Engines, or AppliancePartsPros is usually a better source than a flaky marketplace seller, and the genuine arm is cheaper than the $8 to $15 aftermarket listings.
What the part actually is
Husqvarna’s catalog name, “Arm Spring Brake Mower,” is written in catalog order: arm, for the spring, of the brake, on the mower deck. The part is the stamped-steel arm in the photos, part of the linkage that pulls the blade brake on when you disengage the blades, and the blade-brake spring hooks to it. It is not the spring. The spring, and the anchor bracket at the spring’s other end, are separate parts with their own numbers on the deck diagram, and listings that describe this arm as an “arm spring” are repeating the catalog name, not describing a spring. If your arm is bent or missing, this is the number. If the arm is fine and the brake is weak, look at the spring instead.
The 532-prefix cross-walk
AYP (American Yard Products) built lawn tractors for Sears/Craftsman and later became part of Husqvarna, so the same parts appear under multiple brands. AYP and Husqvarna prepend a 532 to the base part number, while Craftsman lists the base six digits alone. So 165890 and 532165890 are the same physical part, and the conversion is mechanical: add or drop the 532. Once you internalize that, half the “I cannot find this Craftsman part” problems disappear, because the Husqvarna catalog (well stocked and widely sold) carries it under the 532 number.
This is exactly the kind of cross that lets you escape a single bad seller. The part is not rare; it is just listed under a number you were not searching.
The number moved again: 532165890 is now 529845801
The 532 cross is still the key, but Husqvarna has superseded 532165890 to 529845801. Authorized dealer husqvparts.com shows the old number as “superseded to 529845801” with no price, and lists 529845801 in stock at $5.99 (September 2026) with the same “Arm Spring Brake Mower” description and the same UPC, which points to a renumbering rather than a redesign. AppliancePartsPros lists the new number as a “Service Kit” version of the arm, so check what the listing says comes in the box before ordering the spring separately.
In practice, search all three numbers. Older diagrams and marketplace listings still say 165890 or 532165890, dealer stock is moving to 529845801, and AppliancePartsPros still lists the 532 number while showing the new one as unavailable. Its cross-reference also notes that 532165890 itself replaced an earlier 532176925, so a very old diagram may show that one. As far as the listings show, the physical part has not changed; only the number on the bag has.
What it fits
Craftsman LT1000, LT2000, LTX, and YT3000 plus the AYP/Husqvarna LT and YT family of the same era. The brake spring arm is shared across the 532-family deck designs from roughly 1998 to 2010, so confirm your deck generation and the assembly diagram before ordering.
How to use it
- Convert the number. Craftsman 165890 becomes AYP/Husqvarna 532165890, which Husqvarna has superseded to 529845801. Search all three.
- Check the companion parts. The arm is one piece of the blade-brake linkage. The spring that hooks to it and the anchor bracket at the spring’s other end (the dealer lists an “Anchor Spring Brake Mower,” 531165001, formerly 532195784) are separate numbers, and the forum thread also mentions 272680 and 272681. Confirm on your deck diagram which of these you actually need before ordering.
- Buy from a vendor that ships. Dedicated parts retailers like PartsTree, Jack’s Small Engines, and AppliancePartsPros list the Husqvarna number with stock status, and authorized Husqvarna dealers are where 529845801 shows up in stock, which beats waiting on a slow marketplace seller.
If the marketplace order has already stalled, cancel it and order the 532 number from a parts site. You will likely have the part in hand before the original would have shipped.
The buying landscape
| Tier | What | Price | Notes |
|---|---|---|---|
| Genuine, current number | Husqvarna 529845801 from an authorized dealer (husqvparts.com) | $5.99 | In stock at check; the number dealers are moving to |
| Genuine, old number | Husqvarna 532165890 at AppliancePartsPros | $7.54 | Out of stock at check, usually ships in 4 to 14 days; affiliate link below |
| Aftermarket | Aftermarket listings under 165890 (HD Switch, ANTanky, etc.) | $8-$15 | Confirm the listing is the arm and not just a spring |
| NOS and marketplace | Jack’s Small Engines, PartsTree, and eBay listings under 532165890 | $18-$45 | Correct part; Jack’s and PartsTree ship reliably, on eBay check the seller’s shipping record |
Prices above are approximate: the dealer and AppliancePartsPros rows were checked in September 2026, the aftermarket and marketplace rows in June 2026, and all are subject to change. Confirm the current price at the retailer before buying.
For this particular part, the parts-diagram sites tend to be the better channel than eBay, both for stock and for confirming you have the right spring in a multi-spring assembly. Search 529845801 and 532165890 on a parts site, confirm against the deck diagram, and order. With the genuine part at $6 to $8 from a dealer or AppliancePartsPros, an aftermarket arm mostly makes sense when both genuine numbers are backordered.
Where to buy it
- Husqvarna 529845801 at husqvparts.com: the current genuine number from an authorized dealer, in stock at $5.99 when I checked. No affiliate relationship; it is here because it had the part.
- Husqvarna 532165890 at AppliancePartsPros: the genuine part under the old number; out of stock when I checked and usually ships in 4 to 14 days.
The takeaway
- Craftsman 165890 is AYP/Husqvarna 532165890; the 532 prefix is the universal cross.
- Husqvarna has superseded 532165890 to 529845801; dealers stock the new number and AppliancePartsPros still lists the old one.
- The arm is not the spring: the blade-brake spring and its anchor bracket are separate numbers on the deck diagram.
- Buy from a parts site that ships (a Husqvarna dealer, PartsTree, Jack’s, or AppliancePartsPros) rather than a slow marketplace seller.
- The genuine arm was $5.99 to $7.54 when I checked; aftermarket listings run $8 to $15.
- The 532 cross applies across the Craftsman/AYP/Husqvarna LT and YT family.
One slow seller does not control your rebuild. Convert 165890 to 532165890, search 529845801 too, order from a parts site with real stock, and the missing deck spring arm shows up while the original order is still “processing.”
