211-7826 2117826 Cylinder Liner for Caterpillar 3508 3512 3516 Engine

211-7826 2117826 Cylinder Liner for Caterpillar 3508 3512 3516 Engine Rebuilds

The 211-7826 2117826 cylinder liner is used for Caterpillar 3508 3512 3516 and related 3500 Series engine rebuild applications. It is commonly ordered when a large diesel or gas engine shows liner wear, coolant-side corrosion, low compression, piston scuffing, coolant contamination or repeated sealing failure.

This page is focused on the 211-7826 liner group only. The old page title uses E3512 E3516 Excavator, but the stronger technical direction is Caterpillar 3500 Series engine service. Final fitment should be verified by engine arrangement, old liner dimensions and related reference numbers before ordering.

Identification Data for 211-7826 2117826 Cylinder Liner

Application Scene: Caterpillar 3500 Series Power Unit Maintenance

The 211-7826 liner should not be treated as an excavator-only part. Caterpillar 3500 Series engines are widely used in generator sets, power modules, mining trucks, large loaders, dozers, marine engines, industrial power units and other heavy-duty equipment.

For generator and power module service, this liner may be ordered during scheduled overhaul, coolant leakage repair or long-hour engine rebuild. For mining trucks and large loaders, it may be needed after high-load operation, overheating, dust exposure, piston damage or liner sealing failure.

Because the same 3500 Series engine family appears across many equipment types, the safest confirmation method is engine information plus removed liner measurements, not the equipment model alone.

Why This Page Should Not Keep the Old Cylinder Liner Directory

The old Product Description lists many liner numbers for Komatsu, Cummins, Caterpillar and Mitsubishi engines. Those numbers may be useful in a category guide, but they should not remain inside a single 211-7826 product page.

Keeping unrelated numbers such as 3904167, 3904166, 3919937, 3802407, 3022157, 5I-7523 or ME013366 can make this page look like a general cylinder liner catalog instead of a focused page for Caterpillar 3500 Series cylinder liner replacement.

For better SEO clarity, this page should focus on 211-7826 2117826, Caterpillar 3508 3512 3516, 170 mm bore reference, related reference numbers and engine rebuild checks.

Common Repair Situations for 3500 Series Engines

Replacement Reference and Availability Check

Cat official parts data currently shows 211-7826 as a discontinued cylinder liner. This does not mean the page should be deleted, but the content should describe the item as a replacement liner reference and encourage buyers to verify the old liner and replacement number before ordering.

Some aftermarket listings connect 211-7826 with references such as 118-9494, 110-6993, 8N-6861 and 523-8663. These numbers can be used for checking, but they should not all be pushed into the main SEO title.

If the old liner is available, compare the part number mark, bore, total length, flange area, lower sealing area and seal groove position before shipment.

Pre-Order Verification Checklist

Before ordering 211-7826 2117826, confirm the engine model, engine arrangement, old liner number and physical dimensions. Key checks include bore, outer diameter, total length, flange area, sealing area diameter and seal groove position.

If the liner is for a generator set, power module, marine engine, mining truck or heavy equipment engine, provide the engine nameplate and machine information together. Engine data is more reliable than machine category alone.

If the engine has been rebuilt before, provide the rebuild history or removed liner measurements. Mixed aftermarket parts, previous machining or discontinued reference changes can affect the final confirmation process.

Installation and Maintenance Notes

Clean the cylinder block liner bore, counterbore and sealing area before installation. Rust, scale, old seal residue, burrs or coolant-side pitting can damage sealing rings and cause coolant leakage after assembly.

Check liner protrusion according to the engine service manual. Uneven liner height can affect fire ring loading, cylinder head gasket life and combustion sealing.

During overhaul, inspect pistons, piston rings, injectors, cooling system, lubrication quality, turbocharger air path and air filtration together. A liner replacement can fail early if the original cause was overheating, dust ingestion, poor lubrication or injector-related piston damage.

After rebuild, monitor coolant level, oil condition, crankcase pressure, exhaust smoke and operating temperature during the first operating period, especially on generator sets and mining equipment that return to high-load service quickly.
