Front Axle Support Breather plug - L2800 HST

[JD1900]

There is a support in front of and behind the front axle. Each support(compartment) has its own zerk. Yet only the front support has a breather. Are the two compartments where grease is pumped into connected, such that in either case when pumping grease through a zerk, grease would discharge from the breather(plug removed)?

Thanks

I have the same question . . Beuller??

I believe the reason is, the rear support is not sealed so excess grease can escape where the front support is sealed and over greasing could either rupture the oring seal or pop out the sealing cap.

Bingo! That is exactly why it's that way.
