Outboard Motors of the series Windand in particular the model Wind 8For decades, they have been the workhorses of domestic boating and recreational fishing, and their simple design and maintainability allow them to operate for years, but it is simplicity that often leads to neglect of maintenance. One of the critical components that require regular attention is the diewood unit, where torque is transferred to the propeller.
The right choice transmission oil In the case of a gearbox, it's not just a formality, it's a condition of survival in an aggressive aqueous environment. Unlike car engines, the gearbox of a outboard motor operates in conditions of constant temperature drop, high pressure and the risk of water entering through the glands. A mistake in choosing a lubricant can lead to rapid destruction of gears, corrosion and, as a result, expensive repair or complete replacement of the unit.
In this article, we will discuss in detail what specifications should be in the oil for the Wind 8You'll learn why modern synthetic compounds can be better than mineral compounds, and how to correctly diagnose the condition of the node by the color of the workout.
Technical requirements for lubrication of the wind reducer 8
gearing of the motor Wind 8 It's a conical gear with a vertical shaft, and the gear teeth are subjected to tremendous compression and shearing stresses when they're working, especially when they're starting abruptly or moving in areas that are overgrown with algae, and it requires oil that has special anti-sharp properties to protect the metal from bulls and wear.
The main standard to be guided by when choosing is the specification. API GL-5This class of oils contains the necessary additive package (usually based on sulfur and phosphorus) that create a protective film on the surface of the metal. The use of GL-4 oils or motor oils is unacceptable, since they cannot withstand the pressure in the contact spot of the conical gear teeth.
As for viscosity, for most operating conditions in temperate climates, the best choice is oil with a viscosity class. SAE 90 This is in line with the domestic TAD-17 and TAD-17 standard. In colder regions or for winter storage, less viscous options such as SAE 80W or SAE 85W can be considered, which provide better pumpability at low temperatures.
Special attention should be paid to the compatibility of oil oils. Rubber seals in older engines can be sensitive to the aggressive components of some modern synthetics. Motul, Shell or LukoilThey have a neutral composition that is safe for rubber.
⚠️ Attention: It is strictly forbidden to use in a gearbox. Wind 8 Waste motor oil, nigrole or industrial oils (spine rods) that don't have the necessary anti-sharp additives will cause the gear teeth to quickly stain.
If you can’t find specialized outboard motor oil, use the GL-5 API car transmission oil with 80W-90 or 85W-90 viscosity.
Oil volume and frequency of replacement
One of the most frequent questions owners have is the exact amount of fluid needed to fill the gearbox. Wind 8 (as with most modifications of the Winds) the design volume of the crankcase gearbox is approximately 0.3 litres However, when completely replaced with washing or simply draining the work, it is recommended to have a reserve of about 0.5 liters to be sure of full filling the volume without air traffic jams.
The replacement procedure depends on the intensity of operation. If the motor is used rarely, on a weekend fishing, then change the oil in the gearbox should be done. once-yearlyPreferably before winter conservation or early navigation, with heavy commercial use or frequent waterfalls, replacements are made every 50-100 motor hours.
There is an important nuance: the initial oil change in a new or newly repaired engine is recommended after the first 10 hours of running, which will remove metal shavings formed during the grinding of the gears, and assess the condition of the unit.
Oil monitoring should be done regularly, and before each release, it is useful to unscrew the control plug (top stopper), if oil flows from there, the level is normal, if an emulsion or water leaks, the leakiness is broken.
How to determine the need for replacement: color diagnosis
Visual analysis of waste oil is the easiest and most effective way to diagnose the condition of the reducer Wind 8The color and consistency of the fluid can tell us a lot about the processes that take place inside a closed node.
- 🟤 Dark brown or black: This is a normal working state. The color changes because of the additives and the microscopic production of the metal, and if the oil is not shaving metal and the consistency is uniform, the knot is in good shape.
- 🥛 The color “coffee with milk” or emulsion: The most alarming signal is that the gearbox has been hit by water, and the reason is the wear of the crankshaft cuff or the lower unit shaft, and if you use this oil, you'll corrosion the bearings and gears.
- ✨ Presence of sparkles or shavings: If you see large metal particles in a magnetic cork or oil stream, it means that the bearings or gear teeth have collapsed. You need immediate repair.
- 💧 Too fluid consistency: If the oil has become like water, it may have overheated or diluted with fuel (if the seals malfunction), which also requires intervention.
It's important to distinguish between normal darkening and criticality. Light darkening is a workflow. The appearance of heterogeneity, flakes or a sharp smell of burning is a sign of malfunction.
⚠️ Attention: If you find an emulsion (mayonnaise) in the gearbox, don't just replace the oil, you have to find and eliminate the cause of the water, otherwise the new oil will also become useless after a few hours of operation.
Emulsion in the gearbox is always a sign of a violation of the tightness of the ossels, and not the natural wear of the oil.
Instructions for oil replacement in the gearbox
Lubrication replacement procedure in the gearbox Wind 8 It's technically simple, but it requires a sequence of actions to ensure the quality of the result. You'll need a syringe of oil (manual or pneumatic), a working tank, rags and, if necessary, a pad for traffic jams.
The first step is always to drain the old oil, the motor must be installed vertically, both the bottom (leak) and the top (control / filler) plugs are unscrewed, the oil flows spontaneously into the prepared container, it is recommended to sway the lower unit slightly to speed up the process.
☑️ Oil change checklist
If the oil was emulsive, the gearbox needs to be washed, and you can use a small amount of pure transmission oil or a special washing compound, chat the engine and drain the liquid, and then start filling.
The new oil is only poured through bottom-hole. The syringe is inserted into the bottom hole, and the oil is fed until it starts to flow out of the top hole, which ensures that there is no air traffic jams, first the top plug is twisted, then the syringe is quickly removed and the bottom plug is twisted.
The timing of the plugs should be moderate. The aluminum case of the gearbox is easily damaged by excessive force, and the thread is ripped off. It is quite tightened with their hand with a little effort of the key.
Table: Recommended types of oils for Wind 8
To simplify the choice of a suitable lubricant, below is a table with the most common options that have proven themselves in the operation of domestic outboard motors.
| Type of oil | Examples of markings | seasonality | Features |
|---|---|---|---|
| Mineral | TAD-17i, Lukoil TM-5 | Summer/Warm water | Budget, requires frequent replacement, thickens in the cold |
| Semi-intelligent | Motul Gear 300, Shell Spirax | All-season | Optimal balance of price and protection, stable viscosity |
| Synthetics | Castrol Syntrax, Mobil Delvac | All-season/Cold | High cost, excellent protection, long service life |
| Boat special. | Yamalube Gear Oil, Mercury | All-season | Especially for aquatic environment, protection against emulsification |
Can different oils be mixed?
Theoretically, the same class of oil (GL-5) can be mixed, but it is not recommended, different additive packages can react, which will reduce the protective properties, it is better to completely drain the old oil before pouring the new one.
Frequent errors in the maintenance of the reducer
Despite the simplicity of the design, owners often make mistakes that reduce the life of the engine. Wind 8One of the most common is trying to pour oil through the top hole, which inevitably leads to an air plug at the bottom of the gearbox, where the main gear is, and the gears run dry and quickly fail.
Another mistake is ignoring the state of the corks and the sealing rings. Aluminum plugs deform over time, and rubber rings tan. If the cork oozes or the cork twists too easily (throws the thread off), the tightness will not be ensured. Always have a remix of the corks at hand.
Also, you should not save on volume. If you pour less than 300 grams, the oil level may be below the upper tooth of the gear, which will lead to insufficient spraying and lubrication of the upper bearings. It is better to buy a liter canister and be sure of the result than to add "by eye".
⚠️ Attention: Never start a motor with the gear stoppers open or without oil. Even short-term dry work at high revs can lift the surface of the gears.
Compliance with these simple rules and the use of the right materials will allow you to use them. Wind serve faithfully for many years, delighting with stable traction and reliability on the water.
FAQ: Frequently asked questions
Can 10W-40 engine oil be used in Wind 8 gearbox?
No, you can't. Motor oils don't have the EPs required for hypoid and conical gears. Using motor oil will cause accelerated wear and noise on the gearbox.
What is the exact amount of oil required for Wind 8?
The design volume is about 0.3 liters (300 ml). However, when buying it is better to focus on the containers of 0.5 or 1 liter, since some of the oil will remain in the syringe, and it may also be necessary to wash the knot.
What to do if water gets into the gearbox?
You need to immediately drain the emulsion, thoroughly wash the gearbox with pure oil or diesel (with subsequent purge), replace the diewood shaft glands and only then pour fresh oil.
How often should I change oil if the boat is in the garage?
Even with simple oil, it ages and can gain moisture through the oil glands. It is recommended to change the oil at least once a year, preferably in the fall before canning, to leave the knot for storage with a clean lubricant.
Do I need to warm up the gearbox before draining the oil?
If the engine is just running, the oil will be more fluid and will merge faster and fuller, and if the engine is cold, the viscosity will be higher, and the process will take longer.
