Classical reverse Mercury Mariner noises and some tips to maintain your gearbox
Why does the reversing of my Mercury Mariner make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The noise caused by the reversing of your Mercury Mariner is logical. It can be explained in a fairly simple way. In fact, the gears used for conventional speeds (1st to 5th or 6th) are so-called “helical” gears (oblique gears) . The use of such a pinion makes the noise caused by the gears more quiet than with spur gears employed for the reverse gear.
Tips to limit wear on your clutch and gearbox
- Don’t give a big boost:
In fact, if you kick the throttle hard when you are in reverse or when you put the vehicle in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the vehicle is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad idea. In fact, the pressure you will apply on the gears will be enormous and you will produce a premature wear and tear of the gears. You can even break the gears of your gearbox at speed by doing so. It will therefore be completely typical if you find out a reverse noise on your Mercury Mariner if you shift gear under these conditions.
Diverse Mercury Mariner reversing noises and their origins
Finally in this section, we will move on to what you are probably most curious about in this page, to learn about the origin of reversing noise on Mercury Mariner. Here are the 3 typical sounds you may be victim of.
I find out a grinding noise when starting in reverse gear
If you hear a grinding noise when you start in reverse with your Mercury Mariner, it may be the engine mounts that are tired. Indeed, when the engine is in reverse gear, due to the pinions we saw above the vibrations made by the gearbox are higher and it is therefore conceivable that due to their wear the silentblocks no longer absorb the engine vibrations well. In this circumstance, do not hesitate to check out this content for more information about strut mount noises on Mercury Mariner.
An increased reverse knocking noise on Mercury MarinerX
If you are subject to a knocking noise when you are in reverse with your Mercury Mariner and this noise tends to amplify as you gain speed. It is conceivable that you are dealing with a serious issue that needs to be fixed quickly before destroying your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will spread to the rest of the box and damage other gears in short order. Take your vehicle to your technician quickly or read this content about gearbox noise on Mercury Mariner for more data.
I notice a noise when I go in reverse
Experiencing a noise when you shift into reverse is normal and linked to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Mercury Mariner reverse gear makes more noise than before, it is conceivable that filings have been produced and are moving around in it. It is therefore time to empty the box.
