Hydrovane 5 compressor

Post #1 by hair bear » Mon Sep 14, 2020 8:13 pm

Hi,
A while ago I inherited a Hydrovane 5 compressor. Up to now it's been 100% but recently has been more noisy in so much the whirr is slightly louder than it was. Then yesterday on shutdown it started to make 'air escaping gurgly noises' and crapped out a load of pink gunk from under the motory end of the pumpy bit (sorry for the technical terms). :wtf:
Joking aside, the escaping air only lasted around 30 seconds and the receiver stayed up to pressure so I guess the escape is just the residual in the pump. As for the pink stuff, well I assume it's oil. To take a line from the eskimo story "Looks like I've blown a seal..."
So as I have no clue on the construction aspects of this thing, before I tear into it are there any pitfalls I'm likely to encounter? Or, anyone near Aldershot willing to take a look?
Thanks.

Rob the pink stuff is lubrication oil; check the level is okay.

I sort of guessed it was, as I was in a hurry to inflate a slow puncture that I really should have fixed months ago I wasn't in a position to investigate further at that point. I've looked at a couple of videos regarding servicing but I have yet to find one that explains how and where the oil is contained, or how to separate the motor from the pump, it's probably quite straight forward but there is always one poxy little spring or similar that escapes when you least expect it and that's what I want to avoid!
So do we know the type of pink stuff we should be using?

Hi Rob,
The oil is usually a 10W20 specially formulated for use in a vane compressor like Morris's Airforce 4000.
The Hydrovane compressor is pretty straightforward to work on.
Good luck.
Fred
