Description
Solé Diesel On Board Pack service case for Mini-74
The Solé Diesel On Board Pack is a genuine service case containing maintenance and spare parts for the Solé Diesel Mini-74 marine diesel engine. The case has been assembled to keep essential engine maintenance parts organised and readily available on board.
The kit contains parts for replacing filters, servicing the seawater pump and replacing components subject to wear. This makes the service case suitable for periodic maintenance and as a spare parts kit during longer voyages.
Kit contents:
- Oil filter: For removing dirt particles and contaminants from the engine oil.
- Fuel filter: For filtering diesel fuel and protecting the fuel system against contamination.
- Air filter: For trapping dust and dirt particles from the intake air used for combustion.
- V-belt: Spare drive belt for mechanically driving engine components, including the alternator.
- Impeller overhaul kit: Impeller with matching gasket for seawater pump maintenance.
- Anode with holder: For protecting designated metal components of the cooling system against galvanic corrosion.
- Storage case: Solé Diesel case for keeping maintenance parts neatly organised.
The service case contains essential maintenance and spare parts for the engine but does not include engine oil. The specified engine oil must be ordered separately to perform a complete service.
Technical specifications
Brand: Solé Diesel
Product type: Service case / On Board Pack
Version: Mini-74
Application: Periodic maintenance and spare parts on board
Supplied as: Maintenance parts in a storage case
Engine oil included: No
Suitable for Solé Diesel marine engines
This service case has been assembled for the following Solé Diesel marine diesel engine:
Suitable for:
Solé Diesel Mini-74
Before ordering, check the exact engine type and version. Separate service cases with different contents are available for the Mini-74 Genset and Mini-74 Genset TAC.
Oil capacity per model:
- Solé Diesel Mini-74: Engine oil (including oil filter): 10.0 litres
According to the Solé Diesel engine manual, the oil capacity is 9.0 litres when changing the engine oil only and 10.0 litres when the oil filter is also replaced.
When changing the oil, always check the exact engine version and the corresponding maintenance manual. After filling, check the oil level using the dipstick and do not fill the engine above the maximum oil level.
Recommended engine oil:
For an engine oil change, you can use the following genuine Solé Diesel engine oil:
- 5 litres Solé Diesel engine oil (viscosity: SAE 15W-40, ACEA E5/E3, API CH-4): Click here to buy
For the Mini-74, two 5-litre containers are required to provide the specified 10.0 litres, including the oil filter. Engine oil is supplied separately and is not included in the service case.
Essential spare parts for your voyage
A marine diesel engine must remain reliable, even during longer voyages. With the Solé Diesel On Board Pack, essential maintenance parts are readily available whenever maintenance or an unexpected repair is required.
A damaged impeller can disrupt cooling water circulation, resulting in insufficient engine cooling. A worn or broken V-belt can cause problems with the drive of connected engine components.
Keeping suitable spare parts on board allows certain faults to be repaired more quickly, provided the necessary knowledge and tools are available.
Maintenance of the lubrication and fuel systems
The oil filter removes dirt particles, soot and wear particles from the engine oil. This helps protect moving engine components against wear caused by contaminants.
The fuel filter helps remove dirt particles from diesel fuel before they reach sensitive components of the injection system. A contaminated fuel filter can restrict the fuel supply and cause problems such as difficulty starting, irregular engine operation or loss of power.
Replace the filters according to the Solé Diesel maintenance schedule. It is recommended to replace the oil filter at the same time as the engine oil.
Seawater pump maintenance
The included impeller overhaul kit is intended for seawater pump maintenance. The impeller ensures that seawater is pumped through the cooling system, helping to dissipate heat from the engine.
Wear, ageing or dry running can damage the flexible impeller blades. This can reduce cooling water circulation, increasing the risk of engine overheating.
When replacing the impeller, also inspect the pump housing and pump cover for damage or wear. Use the matching gasket to ensure a proper seal on the pump cover.
V-belt inspection and replacement
The V-belt provides the mechanical drive for designated engine components, including the alternator. A properly functioning V-belt is important for reliable battery charging while the engine is running.
Regularly inspect the V-belt for cracks, wear, damaged edges and correct tension. A slipping V-belt can cause squealing noises and reduce the drive to connected components.
It is advisable to keep a suitable spare V-belt on board so that a damaged belt can be replaced if necessary.
Cooling system protection
The included anode is designed to protect designated metal components of the cooling system against galvanic corrosion. The anode gradually deteriorates during use and must be inspected and replaced according to the maintenance instructions.
When replacing the anode, also check the anode holder and seal to prevent leaks.
Important considerations
This service case has been specifically assembled for the Solé Diesel Mini-74 propulsion engine. The kit is not automatically suitable for the Mini-74 Genset or Mini-74 Genset TAC.
Check the exact engine type before ordering. The service case contains maintenance and spare parts but does not include engine oil or a complete tool kit. Always follow the Solé Diesel instructions and maintenance intervals when performing maintenance.
