How to check the gear box oil level on a Vespa ET4 scooter

Promote long engine life and prevent expensive engine seizures

The gears and bearings on the Vespa ET4 experience a great deal of stress during normal useage. To prevent excessive wear and keep them running smoothy, they need a minimum level of gear oil.

Checking the gear box oil level on the Vespa ET 4 (150cc model) is very simple and straight-forward. The five minutes spent checking the oil level could save you from an expensive repair bill and a nasty crash.


Instructions

Step 1

Park the scooter

Park the scooter on a flat stable surface using its center stand.

Step 2

Find the gear box dipstick

The dipstick on the Vespa ET4 150cc engine is on the top of the rear part of the engine.

In this photo the gear oil dipstick is the blue knob.

Step 3

Remove the dipstick from the fill hole

Unscrew the dipstick from the fill hole. Wipe it clean with a clean cloth or paper towel. Rescrew the dipstick completely into the fill hole. Wait 5 seconds. Unscrew the dipstick and inspect.

Step 4

Reading the gear box oil dipstick

The gear box oil level should be between the MIN and MAX marks on the dipstick.

Stock Vespa ET4 dipstick (black) — There are three marks on the stock dipstick. The bottom mark is the MIN mark and the top mark is the MAX mark.

Jettin Industries ET4 dipstick (blue) — There is only one mark on the Jettin Industries gear oil dipstick. This mark is near the bottom of the dipstick and is the MIN mark. The gear oil should reach this mark or slightly higher.

Step 6

Add gear oil or replace the dipstick

If the gear oil level reaches the MIN mark. Rescrew the dipstick into the fill hole.

If gear oil needs to be added, use a squeeze bottle or syringe to add 20 cc of oil through the fill hole. Return the dipstick to its normal position. Wait a few seconds and check the oil level again. Repeat until the oil level reaches the MIN mark.

If the oil is dark, dirty, and thick — it needs to be changed as soon as possible.
