Manuals for Baldwin and Baldwin/Dahl Diesel Fuel and Air Filters

The company was founded by J. A. Baldwin in 1936 and started filter production in Wisconsin, USA, before moving to Nebraska in 1953.  The company was bought by J. L. Clark Manufacturing in 1981, later known as Clarcor.

In 2017, Clarcor was bought by Parker Hannifin - the same company that makes Racor filters.

Dahl is a trademark (brand) owned by Baldwin.

3 simple steps to make your diesel system reliable and robust

STEP ONE  - Get the manuals for your equipment

Owner, Workshop and Parts Manuals are important documents that should be part of every vessel's library. They contain the detailed information necessary for safe operation, maintenance and correct servicing.  

The manuals on this page are provided for public information and education and can be downloaded for free.  All copyrights belong to copyright holders stated in the documents.

congratulations - by downloading these free manuals you are taking an important step towards making your engine more reliable and robust.


STEP TWO - regular maintenance

Simple, regular maintenance is the easiest, quickest and cheapest way to avoid problems and accelerated engine wear. Most expensive repairs start from a lack of basic maintenance or ignoring small warnings. The work is not difficult - it just needs to be done.

The purpose is so that we can enjoy our boat for all the reasons we bought her. Trust yourself. Do the work regularly and be methodical.
