Welcome to R.J. Bastyr, Inc.

Caterpillar Fuel Injection Pump Specialists

We are proud to be the only Caterpillar-dedicated firm in the U.S. with an exclusive focus on the legendary 3200, 3300, and 3400 family of engines.  

Our humble origins began by setting out to establish a new industry-leading standard for remanufacturing caterpillar fuel injection pumps.  While we have broadened out to cover a fuller spectrum of parts needs, we will never stray from our roots.

The Problem:  Historically, many general service shops had reasonable competence with older engines. Unfortunately, reliable fuel injection pump service has always been spotty with these shops.  We got into this work because we have always believed there had to be a better way

But the fuel injection pump problem is bleeding over to engines as a whole.  That’s not surprising since the old veterans are retiring and the new breed aren’t trained the same way with these engines.  Along with that,  general service shops need to make room for never ending volleys of new models across all brands.

The fact that older engine expertise is dwindling, means the fuel injection pump problem will only get worse.  We will stay true to our roots as we believe the future need will only grow because of the amazing longevity of these legendary engines.

Custom Work:  We are happy to custom build a fuel injection pump system to meet your needs.   Our  engine services are limited to rebuilds with high performance additions.  We will soon post available high performance options on the Shop page.

Current Parts Availability:  We supply most parts for the 3400 series now.  We can get just about any other part you need with a quote request or call.  For these parts, it might take an extra day to ship. 

How to Reach Us: You can reach us by phone at 218-214-7993 or by email at sales@rjbastyr.com. We are open Monday through Friday from 9:00am to 6:00pm CST.
