A gearbox contains a great many moving
parts. Some of them are submerged in oil and some of them are splashed — that
is, the oil is carried to them by other moving parts.The lubrication is
designed to prevent metal-to-metal contact, between
teeth on gears, for example. gearbox auto oil seals sophisticated technology.The type of oil used depends partly on the
type of gears the manufacturer has designed into the gearbox.gearbox auto oil seals sophisticated technology.
As in the engine, the oil must be able to withstand high temperatures.mechanical oil seals. `Extreme pressure’ additives in some gearbox oils act as solid lubricants on gear teeth when temperature rises above the safe limit of ordinary oils.
The gearbox oil level should not drop noticeably between routine oil changes about every 30,000 miles (50,000 km). If you have to add a lot to correct the level, check carefully for leaks .
Stand the car on level ground before you check the gearbox oil level. On most cars the filler plug on the side of the gearbox acts as the oil-level indicator, but a few cars have a gearbox dipstick.Marks on the gearbox dipstick show the recommended upper and lower limits for the oil level. Pull out the dipstick and wipe it on a clean rag. Replace it, then remove it again to read the oil level.gearbox auto oil seals sophisticated technology.
If it is too low, top up to the upper limit with the correct grade of oil — as specified in the car handbook.Some cars — the Mini and Metro for example — have a common oil supply to engine, gearbox and final drive. The oil level for the whole system is checked with the engine dipstick.Keep the oil up to the upper limit shown on the dipstick, but be careful not to top up beyond this mark.If there is a dipstick, it will be marked with the recommended oil level.With the car level, remove the filler/level plug. The oil should be level with the bottom of the plug hole.mechanical oil seals.
If you have the more usual filler-and-level plug on the side of the gearbox, consult your car handbook to identify it correctly. The side of the gearbox may have other plugs on it to cover adjustment points, for example.To remove the plug, reach through the engine bay, or jack up the car, support it level on axle stands at front and rear, and lie underneath the gearbox.
More rarely, you can reach the plug through an inspection hole in the car floor beneath the carpet.Depending on its type, the plug unscrews with an open spanner, a large, hexagonal Allen key, or a square-ended key.Some cars need a special tool that can be bought from a main dealer for the make of car.
Multi-headed drain-plug or sump-plug wrenches that remove gearbox, axle and sump plugs are sold in accessory shops, but look to see exactly what you need before you buy one.
Wipe the area round the plug with a rag to clean away any grit, then take out the plug.gearbox auto oil seals sophisticated technology.
The oil should be level with the bottom of the filler hole. If you cannot get a clear view into the hole, push a fingertip in. You can feel the oil when the level is correct.
If the level is too low, top up until oil begins to flow out of the hole. mechanical oil seals.Some gearboxes use engine oil, others use hypoid oil. It is important to use only the correct type and grade. Your car handbook will specify what these are.gearbox auto oil seals sophisticated technology.
The typical layout has the gearbox behind the engine and beneath the floor. Some gearboxes have a dipstick instead of the usual filler-and-level plug. Normally you reach the plug from beneath the car. Clean round the area before removing the plug, to avoid letting dirt in the hole.
The hole may be in an awkward position. Reach it with a plastic bottle fitted with a flexible tube through which you can squeeze the oil. Oil is sold in such containers, as well as in larger tin cans.
The plug often has a washer. Examine it and renew it if it is distorted, split or leaking.Replace the plug, taking care not to overtighten it. Gearbox casings are usually alloy and can crack.gearbox auto oil seals sophisticated technology.
