The other 4 cab mount bolts came out without drama using my long 1/2" Ratchet. Gettin' ready to pull the cab.Had to heat the Core Support Mount Nuts with Victor, So I needed to pull the headlight assemblies. Given the DPF was already pretty well dead/loaded from all the short tripping the truck saw early on. Hasn't been 6 months I've replaced the DPF & now the HPFP. I tried to talk him into selling it even though it had been maintained very well & never worked hard.
This was his dad's truck & was inherited after he passed.The reason for the low mileage.
Usually runs strictly Duramax trucks, But has had some Dodge/Cummins & Ford 6.0L's in his fleet. This truck belongs to a long time customer of mine, He owns a Fire Sprinkler Installation/Sales/Service company. I pull the cab to do this.While it's possible to do it with the cab on & I've seen techs do it, I think they must be masochist or something? I'll do a 6.0L HPOP with the cab on, But never a 6.4L HPFP! With most Bosch common rail systems the Pressure Control Valve/Solenoid is replaceable/serviceable separately from the HPFP, Unfortunately.The 6.4L uses a Siemens/VDO K-16 high pressure pump & the PCS/PCV is not serviceable, The pump has to be replaced. Flashing in the latest calibration had no effect. Thought I'd share the latest from the shop.2008 F250 4X4, 86,000 miles, Would randomly set P0088 (Rail Pressure To High) while pulling a trailer.
