Q & A — Catalog Review

Q: Will you explain how the Deves catalog is organized?

A: Since we get calls on the meanings of different specifications in the Deves catalog, I'll take this opportunity to put together a brief guide to the part of the publication that lists engineered sets, starting on page 1.

First, the set application listings are organized alphabetically, primarily by manufacturer. In some cases, a line like Acura has its own listing separate from Honda. Cross references like "Edsel…see Ford" are included for ease of use. Then, the page is divided into 11 columns, each containing information to make sure customers select the correct set of rings.

Column 1 -- Shows makes and model or piston manufacturer's name.

Column 2 -- Gives model year or years.

Column 3 -- Lists number of cylinders.

Column 4 -- Lists standard bore size in millimeters and inches.

Column 5 — 10 -- These columns are numbered 1 — 6 and entries under each number describe the type of ring and its groove width and function. For example, a listing that has 1.59 over 1-K means that the top ring groove width is 1.59 mm, and it is a straight compression ring. 1-SK designates a scraper ring, while 1-O means an oil ring. Entries under three numbers mean that the set contains three rings; four entries mean a four ring set, etc.

Column 11 -- Lists the Deves set number to order.

Tips:

• Ring groove width sizes are given because some manufacturers use several different ring combinations for one model
• Ring specifications, especially on European cars, may not match the car's model year because Deves uses the actual piston manufacturer's specifications, such as Mahle, Kolbensschmidt (KS), and Nural.
• Although depth specifications are not listed in the catalog, this information is critical when a customer is trying to find a ring for an application not listed in the catalog. Call us and we'll provide you with the appropriate information. In most cases it's even possible to make rings to match unusual depth specifications.
• Deves does not list oversize rings, but almost all are available.
