re: pressure/damper hose for bomb query - 5k

[Dave Conner <conner@cfm.ohio-state.edu>]

I agree with Fred...no need to replace hi pressure line cause it's rusty.
The rust probably hasn't caused the bolt to sieze or anything like that.
Leaking would be another story.

It isn't clear from what Fred wrote, but...

The switch to O-ring type fittings started in '89.
The O-ring type hose ends/banjo bolts cannot be used with the components
(bomb/pump/rack) designed to seal with metal washers.  
The O-ring seals require a much larger mating surface.

It >may< be possible to seal with metal washer type hose-end/banjo bolts on
the newer (larger) mating surfaces but I don't know.

Hi Geo;

    Going for the bomb, eh?  Isn't the large fitting you mentioned a banjo
bolt fitting? On your '87 I think this is sealed with aluminium crush
washers - on the later model bombs it is sealed with 2 o-rings. I would
think that once you had this apart, you would find the hose and fitting is
OK, although externally rusty.
    Doesn't the pressure/damper hose come apart where the damper valve is
located? Maybe you can replace the lower half of the hose only. If you get a
new one, the bomb banjo fitting will be grooved for o-rings, so get the
required o-rings as well.

Have a blast!
