The OilEye - Transmission oil sight glass
The OilEye is a high quality, European made oil sight glass that replaces the oil filler plug of your transmission. You check your engine oil and tire pressures regularly but when is the last time you had a look at your transmission oil? With the OilEye installed, you will always be able to check your transmission oil with just a quick glance. In addition to the practical features of this part, it also adds a visual highlight to the bike.
The OilEye is precision machined of aluminum and the eye is made of high quality glass. It is rated for pressure up to 10 bar (140 psi) and temperature up to 100°C (212°F) so you need not worry about its structural integrity. Especially on 2 valve twin engines, the transmission oil can become contaminated by water entering through a loosely fitting or worn speedometer cable boot. The oil then takes on a milky color and if this goes unnoticed, bearing failure is a likely result. On all models, it's possible for the rear transmission seal to fail and for the transmission oil to transfer into the swingarm. The OilEye provides peace of mind and can prevent costly repairs or inconvenient breakdowns.
Installation is very simple: Just remove your original transmission oil filler plug with an 8mm allen wrench and replace it with the OilEye. The OilEye is supplied with a new seal ring and to tighten, you will need a 22mm socket or wrench. A fiber seal ring is included with the OilEye.
