Location of power steering pump on B6.7

Iím taking a Class B Nevada DL test with my DP with a Freightliner Custom Chassis and I need to know the location of the power steering pump on the engine and if it is belt driven or direct. The alternator and AC compressor are belt driven but I cannot see the PS pump. Help! Thanks

You don't say what engine you have, but a common location is to be driven off the front (front of coach) of the air compressor.


Follow the hydraulic lines from the hydraulic reservoir.

Always a good idea to include year of your coach when asking questions .

Here's a photo of a 2007 ISB 6.7 , yellow circle , would be the hydraulic pump mount flange . For this configuration, of the ISB , direct drive.

Thanks for the response so far. I have a 2020 Sportscoach I believe it was built in November 2019 so a 2019 Cummings 6.7 340 hp.

The picture that Skip supplied is correct for the location of the PS Pump. It's a direct drive mounted to the rear of the air compressor on the engine. I know this as I have replaced mine once. I've attached a sample pic of the pump...with the exception that the plugs are where the fluid lines connect.

It's actually mounted on the rear of the air compressor and is to the rear of the coach.

Many configurations of the ISB ; and that's the importance of posting the year , a 2000 ISB would have the compressor mounted to the timing gear cover, under the VP-44 injection pump, and the starter where the 2007 picture I posted has the compressor , starter moved to the other side of the bell housing.
If the engineers weren't changing stuff , they'd be out of a job.

Don't get me started on coolant sensor locations .

Difference between 5.9 and 6.7, even though classed as an ISB. Whatever

Yup, needed to know what engine.



The larger engines (both Cummins and Caterpillar) are as I posted.

It amazes me that when people give out answers....they don't read the post.

The OP stated his engine in the title of his message. Oh well....
