air chamber

[Leroy Eckert]

This is what I think, cannot prove it yet. Still looking.
I think the air chamber is an MGM 30/36 and the tube is nothing more than a vent to allow air in the non-pressurized side to escape when it is actuated. It probably does not make any difference if it is cracked because mine are also and everything is OK. I actually have one tube missing. If you are getting air out of that hose the unit is probably leaking internally around the rod and the unit needs to be replaced. According to what I have read they should be replaced in pairs and with the exact model or equivalent. There are long and short stroke models. I suspect ours are long stroke but I cannot get my b f a under the bus with the air down to get the model and pn. Some BB owners have replaced theirs with Bendix which are less expensive.
I need to find the tube and rubber grommet for mine or replace the units. Mine are not leaking at this time.
Can you see the model and pn on the
unit?
