Solar 280 1998 Parts Catalog – Control Valve Exploded Views and Part Numbers

If you need to identify a part on your Solar 280, the Solar 280 1998 Parts Catalog is what you need. It is a 16-page document printed November 20, 1998 (Rev. EXH98-11) that gives you the factory part numbers for the left-hand control valve assembly. This is not a service manual. It does not contain torque specs or repair procedures. It does show you exactly which O-ring, plunger, spring, or cap goes where. Guessing between a S8000211 and a S8000261 O-ring costs time and money. This catalog ends that guesswork.

Control Valve Breakdown: Section by Section

Figure 6410 on page 6410 covers the L.H. control valve for serial numbers 5001-5674. The exploded diagram shows five sections: main relief assembly (item 17), foot relief assembly (item 19), and the plunger bank with G1, M, T, D2, and A plungers. Each section is labeled with a reference letter (B, C, D, E) and a detail view. The parts list includes part numbers like 2423-1387 for the housing (L.H.), 2424-1145 for the G1 plunger, and 2420-1159 for the main relief assembly. Cross-reference with the column “ICA Replaceable Part” to see if a newer superseded part exists. This level of detail is what you need when ordering from a dealer.

Part Numbers and Supersessions: Factory Print Accuracy

The right column in the parts table shows optional superseded part numbers. For example, key 16 shows two entries: 2182-1387 MANIFOLD ASS’Y and 2182-1387A MANIFOLD ASS’Y. The “ICA Replaceble Part” column gives the current part number. This tells you that the original part has been updated. If you order the older number, you get the wrong piece. The same applies to key 57 (COVER 2430-1068 superseded by 2430-1068A). A third-party catalog will not show these updates. The factory print does. That is why you pay for the OEM document.

Who Needs a 16-Page Parts Catalog?

If you are a shop owner or a DIY mechanic rebuilding a Solar 280LC-III control valve, this catalog saves the trip of driving back to the parts counter with a handful of old O-rings. It also helps the parts counter guy give you the right kit the first time. The catalog covers only the L.H. control valve, but that valve includes the main relief, foot relief, check valves, and all plunger components. If you need parts for the R.H. control valve, look for the corresponding catalog. This one is specific to serial numbers 5001-5674. Verify your machine serial before ordering.

OEM vs Aftermarket: Why the Factory Print Wins

Aftermarket parts catalogs often combine multiple years or skip supersession data. The Solar 280 1998 Parts Catalog is an original OEM print from Solar. The exploded view matches the actual hardware. When you see “PART NO. 2420-1159” and “RELIEF ASS’Y” with a quantity of 1, you know that is the exact part on your machine. No reprints, no guesswork. I have seen aftermarket catalogs mislabel a cap as a plunger. That waste a day. Stick with the source that built the machine.

3 Reasons to Choose the Factory Print

1. You get the exact part numbers for the control valve assembly with supersession history.
2. The exploded diagram shows the correct arrangement of O-rings, back-up rings, and spacers – critical for preventing internal leaks.
3. It includes the serial number range (5001-5674) so you know the catalog applies to your machine. No aftermarket catalog gives you that precision.

This catalog pairs with the factory service manual for the Solar 280LC-III. Use the service manual for torque specs and disassembly steps; use this Solar 280 1998 Parts Catalog to identify every seal, spring, and valve.

Can I use this parts catalog to find torque specs?

No. This is a parts catalog, not a service manual. Torque values are not listed. Use the factory service manual for that.

Does this manual cover the main relief valve assembly?

Yes. Figure 6410 on page 6410 shows the main relief assembly (item 17) with part number 2420-1159. The exploded diagram includes all subcomponents like the poppet, spring, and O-rings. The parts list gives the exact part numbers, quantities, and supersession information. This is essential if you are replacing the relief valve and need to order the correct rebuild kit. The catalog also shows the foot relief assembly and other valve sections. You can cross-reference the serial number range (5001-5674) to confirm compatibility with your machine.
