Adapting to the Industry

industrial pto applications

In today’s market, Tier 4 engine users commonly find themselves limited in applications that require a Power Take-Off (PTO) clutch. This could be because the engine is equipped with a non-SAE housing or because the engine flywheel is not equipped with a stock pilot bearing bore to accommodate the PTO. Whatever the problem, WPT Power has the solution for Tier 4 Engines looking to power a secondary function.

Paired with the WPT Pilotless™ PTO, our Tier 4 Engine Adapters offer a solution for users whose engines are equipped with non-standard housings or flywheels. The Tier 4 Engine Adaptors consist of two separate flywheel & housing rings. The housing adaptor is bolted to the bellhousing, which creates enough depth to mount the WPT Pilotless™ PTO. As a result, there must be an additional adapter installed to accommodate the distance between the flywheel and PTO.  Once the Tier 4 engine Adapters are installed, Tier 4 Engines can now utilize a PTO as applications require. 

The second major issue users of Tier 4 engines face are flywheels that are equipped with a standard pilot bearing bore.  These non-standard flywheels do not allow for the traditional pilot bearing PTO to be mounted to the engine without special adapters being created, adding cost to the engine package.  However, WPT Power solved this issue with our Pilotless™ Mechanical PTO.  Our Pilotless™ design does not utilize a pilot bearing, therefore installation on an engine without a pilot bearing bore is no longer an issue.

Whether it’s mounting a PTO to a Tier 4 engine or another application challenge, look no further than WPT Power for the solution!  Contact a WPT Sales Representative at 940.761.1971 or
