How-to: Thomas EAS Compressor Install

2025 Views 4 Replies 4 Participants Last post by  shupack
For those of you wanting more/faster air for your EAS, here's a pic of the Thomas air compressor I bought from http://www.Rover-Renovations.com and installed in my Rangie today.


There is a write-up of how I installed it over at http://paulp38a.com/99p38a/eas-compressor-replacement/

Dennis/Shupack - I do credit you with the instructions I followed to do the install. If there are any pics in my write-up you find useful for updating your instructions, feel free to use them. Same goes to the moderators on this site... you are welcome to use the write-up or parts of for the benefit of other Rangie owners.

It is faster alright - four and a half minutes to inflate the tank from empty 8)

It is also bigger and noisier than the original unit. With a bit of persuasion, and using the old compressor as a donor it fits in the EAS box, but the lid won't close. Think I'll just cut a hole in the top of the lid so at least the sides are protected from water splashes.

The noise and vibration hasn't bothered me yet. For those who have seen/heard my car, you know it's not the quietest Rangie around thanks to the dual exhaust system

Cheers, Paul.

you are the second person to say it's louder, but in my experience it has been much quieter.

PS...for my rear most mount, I used a doubled over piece of 12 ga. speaker wire looped around the mounting points, which allowed the compressor to sit low enough to close the lid. :) Maybe this is why it's quieter too.

Well, I haven't driven it any distance yet so I can't say for sure if it is noticably louder than the original unit. In the engine bay, I really can't notice it unless I put my hand on it... the compressor that is :) Will see how it goes while driving and from inside the cabin.

I like the speaker wire idea - I've already put some spacers in under the box to prevent rubbing on the body to reduce vibration..
Cheers, Paul.
My Thomas still takes like 6 mins to fill from empty. Maybe being at 6000 ft altitude doesn't help.
Thanks Paul,

I've still got to add your photos/write-up to my valve block oring instructions. maybe I'll just make a link....
