Det är så långt ifrån en kedjetransmission man kan komma.
Drevsatsen sitteri toppen av lådan och en klättrade olja är ett måste.
Och en som tål temperatur och ändå klättrar.
Jag skulle aldrig hälla i nåt annat än 75w-140
och jag skulle alltid ha den något överfylld.
Snackar vi klättrande oljor lämpliga för växelllådor så har nog LE-Oil's bland de bästa.
Three essential attributes when selecting gear oil
Gear oil is made up of two critical components: base oil and additives.
Additives impart desirable properties and suppress undesirable ones.
The additive package is the backbone of the lubricant’s performance, and a strong backbone will provide the performance and protection you need.
When selecting gear oil, there are three essential attributes to consider:
One -
The gear oil must remain thermally stable and not oxidize at high temperatures, thus avoiding the creation of sludge or varnish. Keeping the oil from oxidizing will lengthen drain and replacement intervals. As a general rule of thumb, for every 18 degrees F (10 degrees C) increase in fluid temperature above 140°F (60°C), oxidation will reduce the service life of a lubricant by half.
Two –
If you have an enclosed gearbox application that is heavily loaded or subject to shock loading, you need gear oil with extreme pressure properties.
Gear oil with an EP additive will protect the gear surfaces against extreme pressures.
Three –
Gear oil must fight contamination that enters the system, especially water.
The oil must be able to demulsify, which allows for easy removal of the water from the gearbox.

Jeg tror også at det er feil olje jeg har brukt (har handlet det som forhandler har anbefalt meg).
Kommer til å prøve annen type olje.
'09 Expedition (SDI) og '11 Expedition (E-Tec).
Begge har variatorkit.
'11 mod (på bildet) blir kjørt "hardere" enn '09, men stort sett samme mil-tall pr år.
Flytt innlegg hvis det ble feil, men gearkassa er samme
