Evaluation Of Elastomer Bearings - AH00.10-P-0001-01A
MODEL ALL
Topic: Sub-surface corrosion/flaking of the elastomer due to corrosion, on example BR169/245 rear axle center bearing Component OK
Topic: Front axle hydromount
When new
Peeling/flaking of the elastomer on the core or on the outer bushing is acceptable up to approx. 30%.
This does not impede function in any way and should not be considered defective.
Component OK
Microfissures up to approx. 30 mm in length which do not lead to fluid loss do not impede function in any way and should not be considered defective.
When subjected to cardanic deviation (full steering lock), these fissures may expand by 3-4 mm.
Component defective
Hydromount must be replaced.
Topic: Injection molding film When new
Component OK
During the manufacture of bearings, certain production methods or tools may cause a film to be left after injection molding.
This injection molding film can vary in its extent.
It does not represent a technical problem and should not be considered defective.
Topic: Suspension subframe carrier
When new
Component OK
The bearing exhibits slight peeling from the core.
Peeling of up to 50 % from the core does not impede the function in any way.
The lateral crease can be incorrectly identified as peeling or as a fissure.
Component defective
The bearing has completely separated from the core.
The suspension subframe carrier must be replaced.
