Iseki TU315FE Parts Catalog – Factory OEM Parts Breakdown for TU315FE Tractor

Listen, if you’re working on an Iseki TU315FE tractor and you don’t have the factory parts catalog, you’re guessing. I’ve seen too many guys order the wrong part because they used a generic aftermarket list. This is the real thing: 252 pages of OEM exploded diagrams, part numbers, and interchangeability codes. It covers the Iseki TU315FE Parts Catalog engine from top to bottom. Page 1 gives you the cylinder head. Page 25 covers the fuel system. No aftermarket reprints, no third-party summaries — this is the original Japanese factory print.

Engine Section: Cylinder Head and Block

Fig. 1 is the cylinder head (page 1). Fig. 2 is the cylinder block (page 3). Every bolt, gasket, seal, and stud is listed with its key number and part code. You get the exact part number for the cylinder head gasket, valve guides, and cylinder head bolts. If you need to order a new cylinder head, you pull the number from this catalog. No guesswork.

Fuel System: Page 25 Fig. 13

The fuel system drawing shows the injection pump, injectors, fuel lines, and filters. Each component has a key number and part code. The injection pump (Fig. 15, page 29) is broken down separately. If you see a fuel leak, you match the hose or fitting from the diagram. The catalog uses the official Iseki part numbering system — not a cross-reference that might be wrong.

Valve Mechanism: Page 15 Fig. 8

Valve springs, retainers, keepers, rocker arms, and pushrods — all listed with factory part numbers. The valve mechanism page also shows the valve guides and seats. When you’re rebuilding the head, this is the only source that gives you the correct stem seal part number. Aftermarket catalogs often lump parts together; this one separates each valve component.

Oil Pan and Gear Case Group

Fig. 5 oil pan (page 9), Fig. 6 oil pump (page 11). The oil pan gasket, drain plug, washer, and all the oil pump gears are here. The catalog includes the gear case group (Fig. 2, page 3) with seals and packing. If you have an oil leak at the rear main seal, you can find the correct seal part number — 7659-543-330-00 or the updated 7659-543-370-00. The catalog shows interchangeability codes so you know if a newer part replaces an older one.

How to Read the Parts List

Page 2 explains the column system. Key numbers may have alphabet suffixes (like 14A) when a part splits into multiple pieces. The CHG column marks new or modified parts: A for added, C for changed. Quantity column uses AR for as required, CC for more than 100 pieces per unit. Interchangeability codes tell you if old and new parts swap. This is the same format used in every Iseki factory parts catalog. Once you learn it, you can jump into any Iseki tractor manual and find parts in minutes.

Audience Fit: Who Needs This Catalog?

If you own an Iseki TU315FE tractor, this catalog is your only source for authentic part numbers. DIY mechanics who rebuild their own engines need the cylinder head and valve diagrams. Fleet shops that maintain multiple Iseki tractors use it to cross-reference parts across models. Even a home garage enthusiast who replaces a water pump (Fig. 11, page 21) will need the correct fan belt and gasket numbers. Beginners: don’t rely on aftermarket parts lists that guess the part. Use this catalog, then order from a dealer who stocks Iseki parts.

Source Validity: Factory OEM vs Aftermarket

This is the original Iseki parts catalog printed in Tokyo, Japan. Aftermarket catalogs often omit the interchangeability codes and the detailed column explanations. They might consolidate multiple parts into one line, leading to ordering the wrong seal or gasket. This catalog keeps every split part number separate — for example, the oil pump cover gasket appears as two separate gaskets (Fig. 6, items 16 and 16A) because they changed over the years. You get the exact part that matches your serial number. I’ve been an ASE Master Tech for 28 years, and I’ve learned to trust factory parts lists over any third-party documentation.

Frequently Asked Questions

Does this catalog include torque specs?

No, this is a parts catalog, not a service manual.

How do I find the correct part number if the part has been updated?

Look at the key number — if it has an alphabet letter suffix (like item 14A), the original part was split into multiple updated parts. Check the CHG column: A means added, C means changed. Then look at the ITC column (interchangeability). A code of 0 means old and new are interchangeable; 1 means new can replace old but not vice versa; 2 means old can replace new but not vice versa. For example, the gear case seal changed from 7659-543-360-00 (item 14) to 7659-543-370-00 (item 14A) — the ITC code tells you whether you can use the older part in a pinch. This level of detail is absent from aftermarket catalogs.
