Radial Oil Seals - The Differences
Universal
23.11.2021ATENTION! Following instructions, issued by the manufacturers regarding new PTFE oil seals are mandatory:
A) old version with spring.
B) new design (PTFE) without spring.
B) new design
These radial oil seals have to be mounted "dry", never apply grease or oil to them like it is usual while mounting conventional radial oil seals.
Always use an accurately fitting assembly sleeve, flanges or covers have to be fixed properly before removing the assembly sleeve. Usually the assembly sleeve is included with delivery of PTFE radial seals.
After installation the engine has not to be started until the primary lip has assumed it´s definite shape around the shaft. The adaption period can take up to 8 hours, the exact standby time has to be taken from the individual product´s manufacturer instructions. Disregarding the adaption period will cause immediate leakage of the new radial oil seal!
Standard and PTFE radial oil seals may not be exchanged against each other, always use the type originally dedicated to the car by the vehicle manufacturer.
Attention
Both types can not replace each other! Always use the type that is originally dedicated to the car.
