Wearing Parts for Portable Engines

For the benefit of owners and restorers, this page reproduces descriptions of wearing parts for Paxman portable steam engines offered by the Company in its publication number 683, dated September 1913. The illustrations in the original publication were designed solely for identification purposes and are not engineering drawings. They do however give an idea of what each part looks like.

An image (in GIF format) of each illustration page can be viewed by clicking on the relevant underlined illustration number at the start of each section below. Initially the graphic may display in your browser in reduced and distorted form. In Internet Explorer (IE) v.6 click on the bottom right hand corner of the image, in IE v.7 anywhere on the image, to expand it to its full size.

There are two methods of downloading/saving one of these images to your hard drive: EITHER right click on the relevant underlined illustration number on this page, then select 'Save Target As...' (or equivalent if using a browser other than IE) and save to your desired folder; OR click on the link below to display the image in your browser, then right click on the image, select the 'Save Picture As...' option and save to your desired folder.

PLEASE NOTE: The numbers on this page are not part numbers; they are only for referencing the illustrations in the parts booklet.
