The obliquely placed ribs and the elasticity of the plastic ensure that the oil level sight glass fits firmly into the port that even a limited over- pressurisation can be contained. The window glass is recessed, giving better protection to the window. Assembly instruction: Press in the oil sight glass manually, then possibly use an intermediate layer such as wood or a hammer. Chamfer hole 1x45° and grease slightly the outside surface of the O-ring to make assembly easier. see also... • Oil Sight Glasses GN 537 (without Thread) → Page 1560 Information • Body Plastic (Polyamide PA) - - Temperature resistant up to 100 °C - - Black SW • Sight glass Plastic Cystal clear Polyamide (PA-T) • O-ring Rubber NBR (Perbunan ® ) • Reflector Aluminum - - White lacquered - - With red oil level mark • Elastomer Characteristics → Page 2158 • Plastic Characteristics → Page 2158 • RoHS Specification 4 Original design HRT.
