Unlike automobile spare parts, marine engine parts should always be in good shape. The reason is rooted in the accessibility to resources and repair assistance. An aid may be several nautical miles away when a ship is stuck under extreme conditions in a wavy ocean. At this point, the marine overhaul kits come to the rescue.
In this blog post, we delve into the nitty gritty of overhaul kits and why they are essential for ships.
What are Overhaul Kits for Marine Vessels
It is often impossible to determine the precise time of engine parts failure. Long hours of operation, vibration, forces, and stresses can cause wear and tear in machine parts and the engine body. Upgrading to a new engine is not always necessary when you can manage it all at a fraction of the cost with high-quality overhaul kits. That too without compromising reliability, efficiency, engine health, and performance.
An overhaul kit is a combination package of essential OEM replacement parts from your engine manufacturer brand. These parts are specifically crafted for the concerned engine model for precise fittings and equipment safety.
Marine overhaul kits offer the convenience of replacing faulty parts with OEM items. These parts can replace the chipped, damaged, and faulty engine parts whenever required. This enables marine professionals to restore the engine to its previous condition, ensuring uninterrupted vessel operation.
Types of Overhaul Kits for Marine Engine Repairs
There are two types of marine overhaul kits for engine room equipment repair in ships – in-frame and out-frame packages.
How to choose the type of overhaul kit for your ship?
It all depends on the extent of replacement and repair work needed to reinstall the engine to functioning. Here is an overview of what to expect from these two types of overhaul kits:
In-Frame Overhaul Kits
In-frame overhaul kits comprise a set of elementary parts. As the term suggests, the professional does the overhauling services while the engine is still mounted in the frame. Such replacement operation allows the boat owners to repair the marine engine on-site without detaching it from the equipment setup. In most cases, the engineers do not remove the crankshaft and the front cover from their position.
An in-frame marine overhaul kit for engine repair primarily includes:
- Cylinder Liners
- Pistons and piston rings
- Pins/pin retainers
- Gasket and O rings
- Mechanical seals
Some in-frame overhaul kits contain extra items, such as bearings for the crankshaft and connecting rods.
Out-of-Frame Overhaul Kits
The out-of-frame engine repair is a complex task where the engineers remove the engine from its frame and detach the parts. This becomes mandatory for engines with severe faults, worn-out parts, crankshaft misalignment, etc.
Typically, the repair specialist disassembles the engine block, cylinder head, gaskets, valves, and other parts for a comprehensive inspection. The out-of-frame overhaul kit comprises all items from the in-frame kit and a lineup of additional items, including:
- Pump shaft (with nuts and keys)
- Shaft sleeves
- Coupling bolts
- Distance rings
- Connecting rods
- Wear ring
- Ball bearings
