Essential Bolt Tightening Torques
Our Key Objectives:
- To provide engine specs and technical data for diesel engines.
- To provide items of interest related to diesel engines and about the machines that they drive.
- To provide a forum where anyone may contribute to the industry or to the site, directly by membership, or indirectly by providing information or resources.
- Above all we want to provide a service to our members, to provide data easily, economically, and fast, so that our member's workshop and sales experiences are enhanced with the tools we provide.
- Let it also be an interesting and fun experience every time you visit us.
Membership is about:
We are a club, and every club has members. We have a vast and growing amount of engine specs, bolt torques, assembly clearances, workshop manuals and procedures for so many engines. Some of these specs and data are available to everyone, but so much more is only available to members, as you would expect.Members do not pay for the data they view or download, but there are membership fees which entitle you to enter the club, our web club, to browse around, view and download at leisure.
Membership at Barrington Diesel Club is about being part of what we do with the intent to use that and to grow that. Membership is the key to getting more and more diesel engine specs and technical data related to diesel engines.

Key Engine Specs are about:
Key Specs Concept:
Key specs are basically, the power and torque of the engine, the engine displacement, bore and stroke, the key bolt tightening torques (mains, con rods, and cylinder head), the compression ratio, a picture, if available, plus the dimensions and weight of the engine.
It is a useful tool for anyone in the diesel engine business and it is a recreation for anyone interested in engines.
Quick Specs or key engine specs, is a free and open service of Barrington Diesel Club and does not require membership.
Usually, quick specs appear as a dedicated webpage per engine or sometimes a webpage for a group of engines. The range of manufacturers and engine models, however, will continue to grow and more and more specs will become available to all, in open specs, member specs and manuals.
Additonal Specs and Manuals
When more than quick specs are required:Quick engine specs have links to additional specs for those who require more technical information, such as:
Assembly clearances, a bigger range of bolt torques and workshop procedures. These additional specs require club membership or a club membership window to access such information.
Membership Fees:
Members do not pay for the data they view or download, but there are membership fees which entitle you to enter the web club, to surf the website, view and download at your leisure.

Membership is the key to getting more and more diesel engine specs and technical data related to the diesel engines you want to expand your knowledge of.
1. Horse power & torque are listed for engines normally between 100 to 200 meters above sea level.
2. Horse power & torque given are typical, not specific, and vary from application to application and serial number to serial number.
3. Images are from our archives or from manufacturers spec sheets or manuals or copies from internet open sources e.g. YouTube, Wiki, or Google Images. If we use any image that does not fall into one of these categories and anyone objects, we will remove it immediately upon request.

About Standard Bolt Torques at Barrington Diesel Club
Standard Bolt Torques
Standard torques - Introduction
These are the basic specifications used by
manufacturers worldwide to build engines and all types of machinery, vehicles, aircraft and ships.
No engineer or mechanic should be without tables of this sort to guide them
in their construction, development and repair work.
Imperial Bolts - Standard torques
Imperial High Tensile Bolts are widely found on older American, Canadian and British engines
and machinery.
Largely though, newer engines and machines are gradually adopting metric ISO bolt standards.
However while practical, technical and other difficulties to complete the conversion to the metric
system still remain. I think the imperial system may still be with us for some years to come.
Metric Bolts - Standard torques
Metric system (SI). SI is the abbreviation for the metric system,
the International System of Units.
Metric Bolt Usage: For many reasons standardization of various aspects of engines,
like fasteners, is an ideal many are aiming at.
Ongoing standardization for materials through ISO (International Standards Organization)
has resulted in many popular engine manufacturers largely changing from imperial fasteners
to metric ones. The use of metric bolts and nuts by engine manufacturers like
Detroit Diesel and Cummins on their newer models of engines has now become common place.
Difficulties with metric and ISO systems
From the outside, talking about anything ISO, is fraught with circles of technical jargon.
eg. try finding the correct way to write a bolt's size down on a piece of paper and you'll
wind up having to buy an ISO nomenclature manual costing hundreds of Swiss marks in order to do so.
Then if you do find out before you're bankrupt, you may find that no one on earth except
the real technical boffins understand what it all means anyway.
Other Standards authorities e.g. DIN, JIS, SAE, may and do make their own standards
on an 'ad hoc' basis when the situation demands it or they feel the situation demands it,
and those standards may or may not agree with an ISO standard for a particular thing,
if ISO has a standard for that particular thing in the first place.
For ISO to succeed as a system, or any other system to succeed for that matter,
it needs simplification. Begin at something like an ABC base, where terms, manuals
and protocols are defined and made economically and easily available and usable by the majority
of society during the progress of normal living and activity.
Metric Bolt Terms
Normally metric fastener sizes are stated in mm (millimeters) and begin with a capital M
which is followed by the fastener's nominal diameter and possibly the bolt's thread pitch,
separated by an "x".
If the pitch is not mentioned it defaults to the 'standard metric coarse pitch' for that
size bolt or nut.
For practical purposes we write a bolt's size as follows:
M12 x 1.75 x 60
giving M for metric,
12 for the bolt's diameter in mm,
1.75 the pitch of the bolt in mm,
60 for the length of the working bolt in mm.
When you order bolts you must specify the grade,
check the old bolt for the grade on the head of the bolt.
If you do not see the grade on the head of the bolt, it may be a cheap import,
be careful not to use ungraded bolts, they break.
In any case, for engines I suggest you never use ungraded bolts,
and then never use a lower grade than 8.8.
Metric standard torques do not consider the pitch of a bolt
but do consider wether the bolt is installed dry or if it is oiled before insertion
and then, there is a different torque value for the same diameter bolt.

OEM manufacturers
Advertising material, spec sheets and images from OEM material are used abundantly. We list the current manufacturer's website for reference, however some of the material is historic or no longer in production and may now not be available from them. Nevertheless at one time or other, it was in vogue, with them or their predecessors being the original source.
Material is used from OEM workshop manuals or technical bulletins, which are owned by Barrington Diesel Club or which we have been provided with, which may or may not be out of date, or subject to revision. Please treat all such material with caution, it is listed for reference purposes only.
Other specs and data have been given by word of mouth or given from personal experience.
The sources of these are often obscure, material here used in lieu of more verifiable material being available, and it is to be used for reference purposes only.
We are not and do not imply to be, agents or distributors for any OEM manufacturer and advise you to check all material, specs, torques and assembly clearances obtained from this website with them, before use.
