Description

Overview

The Lycoming Crankshaft, part number LW-10619, is the central rotating component within the Lycoming O-235 series reciprocating piston aircraft engine. Its fundamental role is to translate the linear up-and-down motion of the pistons, transmitted through the connecting rods, into continuous rotational motion. This rotational energy is then delivered to the propeller, generating thrust, and also drives various engine accessories such as the alternator, oil pump, and magneto. As a critical structural component, the LW-10619 crankshaft is engineered to withstand immense cyclic loads, torsional stresses, and high temperatures inherent to internal combustion engine operation.

Frequently asked

Does the Aviation Part LW-10619 include certification paperwork?

This item is supplied as "Condition disclosed" rather than with full 8130-3 traceability — normal for some condition codes, and it does not mean the part is unusable, only that the paperwork profile differs. Check the listing for exactly what documentation is included, and request any available records before you purchase if your installation requires them.

What condition is this part?

This part is listed in condition as listed — Condition disclosed. Condition codes describe how a part reached its current state (for example new, overhauled, serviceable, repaired, or as-removed) and directly affect what paperwork ships with it and how it should be installed. See the Glossary for the full definition of every condition code we use.

How fast does it ship?

This item is currently on backorder, meaning demand has temporarily outpaced our stock and a new shipment is inbound from the manufacturer or our supplier. Request a quote and we will confirm the current estimated delivery window before you commit. If your aircraft is grounded, AOG expedited handling is available on request.

Can I return it?

You may return this item within 30 days of delivery if it is unopened, uninstalled, and in its original packaging. Items that have been installed, powered on, opened hazmat, or separated from an attached 8130-3 tag are non-returnable because their airworthiness status can no longer be confirmed once removed from the part. See our Returns policy for the full process.
