Furukawa Unic UR343-C Parts Catalog – 101 Pages of Factory Spec

If you’re wrenching on a Furukawa Unic UR343-C and you don’t have the factory parts catalog open on your bench, you’re flying blind. I’ve seen guys order the wrong boom bushing three times because they guessed the serial number range. That’s billable hours you don’t get back. This is the Parts Catalog – 101 pages of exploded views, part numbers, and interchangeability notes that Furukawa Unic put out for the UR343-C starting at serial N105251. No reprints, no scanned third-party garbage. This is the same PDF the dealer uses.

Let me walk you through what’s actually inside this manual and why it matters when you’re under a crane that needs parts ordered yesterday.

Parts Breakdown for the UR343-C – What You Get

The catalog covers the entire hydraulic truck crane – boom assembly, sheave slides, bushings, grease nipples, bolts, spacers. Every part has a key number, a parts number, and a description. Page 3 shows the boom ass’y breakout: key 1–43, part 0146 24000 for the boom itself, then details like sheave-slide 200 ass’y (key A3, part 9110 00019). You need a bushing? Key A4, 0211 21130. The manual marks interchangeability with symbols: ○ means new and old parts swap either way, ● means new replaces old but not vice versa, × means no interchange. That info alone saves you from ordering a part that won’t fit a crane built after a certain date.

Each assembly section lists quantity codes: “M” means one per assembly, “R” means required quantity, “Y” means you decide your own quantity. If you see “n” or “ℓ” next to a part, you’re supposed to specify the number or length you need. This isn’t guessing – it’s factory procedure.

How to Read the Mark Column – Avoid $200 Mistakes

Page 4 gives you the legend for the “Mark” column. I’ve seen techs grab a used part that looked identical but had a × symbol – it won’t interchange. The manual spells out: △ = part not for sale (usually a sub‑assembly you don’t order separately), D = disuse (old part superseded), Q = quantity change. If you’re ordering service parts, you need to supply crane model, serial number, assembly name, part name, part number, and quantity. Copy‑paste that information from the manual directly into your order form. No shortcuts – that’s how you get the right piece.

Ordering UNIC Genuine Parts – Why Aftermarket Copies Fail

The manual states flat out: “Use UNIC GENUINE PARTS exclusively for servicing your crane. No warranty can be given on a trouble caused by using a part except genuine parts.” I’ve seen knock‑off bushings wear out in a quarter of the hours. This catalog gives you the OEM part numbers – you call your nearest dealer or service shop with those numbers. The manual also warns that parts are subject to change without notice, so you verify against your crane’s serial number every time.

Serial Number Cross‑Check – Why It Matters

The UR343-C in this catalog applies to cranes from serial N105251 onward. If your crane plate shows a lower number, some parts won’t match. The manual shows interchangeable marks per part – if you see ○, you can use the new part on old cranes; if you see ×, you need the old part number. I keep a printed copy of page 4 taped to my toolbox. Automotive Industry Overview isn’t directly relevant, but the same discipline applies – verify specs before you wrench.

Who Needs This Manual

If you’re a home‑garage mechanic who bought a used UR343-C, this catalog keeps you from ordering parts by eyeball. If you run a shop in San Antonio like mine, you keep a digital copy on the tablet and a printed set in the parts room. Beginners: don’t guess part numbers – look them up. Pros: you already know the value of a genuine OEM parts list. No fluff here – just exploded diagrams, part codes, and ordering rules.

FAQ – Parts Catalog Reality Check

Does this catalog include torque specs or service procedures?

No. This is strictly a parts catalog – part numbers, exploded views, quantities, and interchangeability codes. For repair procedures you need the separate service manual. This one gets you the right metal so you can bolt it on with the correct fastener.

Can I use it for a UR343-C with a serial below N105251?

Check the interchangeability marks. Some parts are marked ○ and will fit older cranes. Others are marked × and will not. You need to cross‑reference against the actual part number for your specific serial.

How do I find a specific part like the boom sheave?

Look at the table of contents – it’s organized by assembly. The boom section starts on page 3. Each key number leads to a part number. Write down the part number and quantity from the “Qty” column, then order that number from your dealer.

Is this a PDF or a printed book?

It’s a digital PDF format. 101 pages, searchable, printable. You get the exact same document the Furukawa Unic factory provides to dealers. No watermarks, no missing pages.

Stop ordering blind. Access the Factory Manual for the Furukawa Unic UR343-C – 101 pages of OEM part data that keeps your crane running and your wallet intact. This is the same spec sheet I use when I’m rebuilding a boom or sourcing a bushing for a customer’s crane. Get the right part the first time.
