CAT Generator Engine Model 3406, Oil Pressure Switch

With the information you have given, Model, Serial, and Arraingment any truley authorized Caterpillar dealer can supply your switch.

In many cases with Caterpillar even if you have a part number, the suppliers will be reluctant to supply the parts unless they are given the S/N and Arraingment to cross reference.

A quick phone call to the nearest authorized dearler will solve your problem.

Yea..... Spell check isnt working and I know full well I cant spell at 05:30!

Contact your nearest dealer with engine serial number only he can help you because your authorised CAT dealer only has access for this information on CAT servers your parts book may not help much, as 3406 family is almost phased out and its difficult to get the parts and if available it would be expensive and leedtime for delivery would be long
