Iseki SSM48, SRM48, SBC 350 Parts Catalog

Let me be direct: if you are turning wrenches on an Iseki mower and need to track down a part number, you don’t want some aftermarket list that skipped half the revisions. You need the factory original. This 86-page Iseki SSM48, SRM48, SBC 350 Parts Catalog is the real deal — printed in Tokyo by Iseki themselves. No third-party interpretation, no greyscale scans where you can’t read the numbers. It’s the same binder the dealer pulls from when you call.

Using This Parts List: The Column Codes Explained

Flip to page 2 and you get the full breakdown of how Iseki codes their parts. You’ve got KEY #, SPC (split part numbers where one part number gets broken into two or more due to engineering changes), CHG (A for added, C for changed), PART NUMBER, DESCRIPTION, QTY, ITC (interchangeability – 0 means full swap, 1 means new can replace old but not the other way, etc.), and S.C. (serviceable parts). That matrix of models at the top of each figure tells you exactly which machine uses that part. If you’ve ever ordered the wrong blade because the listing said “fits all models,” this system stops that. No guesswork.

Which Models Are Covered?

Three decks and a collector system: SSM48, SRM48, and the SBC 350 side-discharge bagger. The SSM48 section (Figures 1–12) covers the cutting deck: universal joint, counter system, bevel case, metal and blade system, mower deck and cover, wheel fork and gauge wheel, front/main/rear link systems, plus marks and decals. The SRM48 section (Figures 13–18) is similar but with its own bevel case and blade setup. The SBC 350 section (Figures 19–28) covers the collector frame, blower frame, casing, pipes, doors, shooter cover, rear PTO sets (for 01 and 02 models), and collector sensor marks. That’s the whole machine from spindle to bagger chute.

3 Reasons to Trust an OEM Parts Catalog

Reason one: The part numbers are traceable back to Iseki’s own engineering drawings. The CHG column shows when a part was modified. If you order #12345A instead of #12345, you get the updated design — not the one that fails after 50 hours. Reason two: Interchangeability codes (ITC 0,1,2,3) tell you whether you can mix old and new stock. That matters when you’re rebuilding a deck that’s had parts superseded twice. Reason three: These catalogs include the asterisk (*) notation for color-coded parts specific to certain countries. If you skip that and order a red part when you need green, it’s on you. The manual warns you upfront. That’s the difference between factory documentation and a third-party PDF that doesn’t even know there are color variants.

Joint (Universal) System: Locating Driveshaft Parts

Figure 1 on page 1 shows the universal joint system for the SSM48. You get an exploded view with every U-joint cross, yoke, and snap ring called out individually. The parts list below the drawing matches each callout number to a key number, part code, description, quantity, and service code. If your driveshaft has play, you look up the joint assembly, find the part code, and order it. No need to disassemble the whole deck to figure out what you need. The same structure applies to every figure.

What About the SBC 350 Collector System?

If you run an SBC 350 bagger, you get a full breakdown from the collector frame (Figure 19) to the blower frame and belt cover (Figure 20), the discharge casing (Figure 21), collector pipes and lever (Figure 22), side collector and open frame (Figure 23), lock and bag system (Figure 24), shooter cover and hose (Figure 25), and two rear PTO sets (Figures 26 and 27) differentiated by model year (01 vs 02). Figure 28 covers the collector sensor and mark system. That’s 10 pages of bagger-specific info. If you’re chasing down a clog or a broken chute hinge, this is how you get the right part number without buying a whole new assembly.

Who Needs This Manual on the Bench?

Home garage guys who bought a used Iseki SSM48 or SRM48 and want to rebuild the deck without throwing money at guesswork. Equipment owners with a fleet of SBC 350 collectors who need to stock the right quick-wear items. Mechanics who charge by the job and can’t afford to order the wrong blade spindle three times. This parts catalog is the reference you use before you call the dealer. It’s also the document you hand to the parts counter when the guy behind the desk says “that part is NLA” — because you can show him the supersession code. The Automotive Industry Overview confirms that OEM documentation is the only reliable source for engineering changes. I’ve been burned by aftermarket translations that swapped a metric thread for an SAE thread. This catalog doesn’t have that problem.

Source Authenticity: Factory Print, Not a Remastered Copy

This is the original Iseki Parts Catalogue, published in Japan. The OCR excerpt shows the exact column headings and figure layout. Every page is legible. You can read the part code, description, and quantity without squinting. The document comes as a PDF that prints clean at 100% scale. If you try to use a blown-up scan from a forum, you’ll miss the ITC codes and the asterisk color marks. This one has them all. For the full service manual to go with this parts catalog, grab the Iseki SSM48, TXG23, SSM60, SSM54, SMM54 Service Manual – 175 Pages OEM. If you need the 2013 model year parts catalog, the Iseki SSM48 SSM60 SSM54 2013 Parts Catalog – OEM covers that. And for other related models like the SF200 or TM215, the Iseki SSM48, SF200, TM215, TMG18, SG173 Parts Catalog – OEM is available.

One more thing: this catalog uses the same numbering system as Iseki’s official parts lookup tool. Once you learn the KEY # and ITC codes, you can move between figures without re-learning a new format. The manual isn’t fluff; it’s 86 pages of exploded diagrams, part codes, and quantity tables. Period. If you want to fix your Iseki mower without playing amateur detective on eBay, this is what you need.

Does this manual include torque specs?

No. This is a parts catalog, not a service manual. Torque values, clearances, and repair procedures are in the service manual. The parts catalog gives you the part numbers to order for the repair.

How do I find the part number for the blade system on the SSM48?

Go to Figure 5 – METAL and BLADE SYSTEM on page 11. The exploded view shows the blade, blade bolt, spacer, and blade holder. Find the callout number (e.g., 12), then look in the parts list on the same page for the corresponding row. The PART NUMBER column gives you the exact code to order. The QTY column tells you how many you need. If the part has been superseded, the CHG column will show a change code. That’s it.
