The pace of new engine technology can be difficult to keep up with. Whether you are rebuilding or ordering parts for a newer engine, the terms that have been developed can be confusing. This month, we have put together a quick reference of terms that you may need to know when dealing with these engines.
In addition, this month’s Featured Product addresses an older application engine that can benefit from the newer technology of piston crown-gallery cooling.

If you did not have an opportunity to complete last month's Survey Issue, please take a few minutes to fill this brief survey now.

Thank you again for your support and we welcome your comments.

IPD Featured Product
IPD announces the release of 1601131 gallery cooled piston for Caterpillar® 3406 / 3408 / 3412 engines.

This piston can be used to replace the 9Y4004 in select applications where piston seizure may be caused by high horsepower and/or temperature conditions. The oil cooling gallery, built in the crown of the piston, helps to reduce operating temperature of the piston and the risk of quarter point scuffing or seizures that are common in overheating conditions. 
When updating a 3406 from a 9Y4004 piston to the 1601131 piston, the cooling jets must be changed from a single configuration to a dual configuration. Jet numbers 1663650 (with .3228" bolt") or the 1979336 (with .4016" bolt) dual cooling jets replace the 7W4990 single cooling jet. The oil pump must also be updated from the 0R9448 to the 0R9449 engine oil pump group. Additional information may be found in Caterpillar® Service Magazine #SEPD0827-00 or other publications for details on applications and required component upgrades.

Please view our DECEMBER 2006 listing of new IPD products to view the combinations of in-frame and out-of-frame engine kits that IPD now offers with this piston.
