holman howden compressor no.4769 1265

Anonymous-0 · Apr 12, 2011

Hi everyone! i'm pretty new here as i'm looking for information on an old screw compressor that i bought few weeks ago. i'm planning on starting up this beast but don't know much about it. I'm an industrial mechanic and i set myself that goal to bring it back to live. I don't know for how long it haven't run. That's a holman howden compressor with a Ford 2711e diesel engine. If anyone of you could help me with any info about that kind of compressor or what i should do first to make sure this thing worth the work of taking it apart... Is there any way to disengage the screw so i can check for the good working condition of the diesel engine before to work on the compressor itself? Or a way to check for the working condition of the compressor? (make sure it's not sease or broken, this way i won't do more damage) You can contact me by e-mail, i have some picture that might help you (if i find the way to upload them here, i will...)
Thanks a lot everyone!

the engine and compressor can be split at the engine flywheel, the compressor can be checked for free turning of screws, and removal of compressor intake cover, allowing a view of the screws and ability to check clearances.

I've got one. There's no way to disengage the compressor without dismantling. Before starting you can check the oil. If the oil hasn't been changed for 20 years it's probably tar by now and the oil pump shaft will break or is broken.
Tips: There's a cold start button located at the axis of the kill lever on the Simms diesel injector pump that'll make starting a lot easier. Those compressors normally wine loudly from the straight cut gears. Don't worry about the gear noise.

Oil pump on the compressor. It's located on the round end that's surrounded by the starwars looking oil separator.

Thanks again and don"t be shy to contact me if anything else come to your mind.

If you reply to the Email I sent I can send you information from a newer model that's still useful.

Hi,
I have one of these in Australia, it goes OK though all the instruments and air controls are shot - I cannot see where to check the compressor oil, there is only a breather cap. Can you direct me?
Thanks,
Steve

Breather cap? There"s no breather cap on mine. It"s pressurized. The comp. oil level is checked with the dip stick welded inside the pipe cap located on the left side.
Maybe we"re not talking about the same machine. The answer to your question seems too obvious.
