APPS Repair

This guide addresses the construction, possible disassembly, and possible repair of erratic or failed APPS units. These throttle control units, APPS (Accellerator Pedal Position Sensor), most frequently seem to fail or become erratic in operation due to deteriorating contact between internal rotating fingers and the resistance track they ride on inside the APPS unit, causing […]

Replacing Front Spring Bushings on a Ford Pickup

The factory Ford rubber spring bushings just didn’t last on my F-350, due in part to the heavy Power Stroke engine. The best replacement for these are urethane bushings. They last much longer and can come embedded with graphite for lubrication to eliminate squeaking. The best manufacturer of these urethane bushings is Energy Suspensions.  I […]

Dodge Cummins Fan Removal

The thread is left hand; from the front of the engine you turn the wrench to the right (toward the driver side). Do this when the engine is cool. Some people pull the entire fan/hub assembly out past the radiator shroud, others remove the fan first, then remove the hub. In many cases, a drift […]

Cummins Diesel Fan Belt Replacement

1. Remove the belt by inserting the drive nose of a 3/8″ ratchet into the square hole in the idler pulley. Use the ratchet to unload the idler tension from the belt by rotating the ratchet counterclockwise as viewed from the front of the engine. The best position for the ratchet is almost straight up […]

Ford 6.0L Intercooler Swap for the 7.3L Powerstroke

The swap is relatively inexpensive and not to time consuming. Used 6.0 intercoolers can be had on eBay for around $100-$125. The 6.0 IC is about 30% larger than the 7.3. The original 7.3 PSD intercooler measures 30x18x2 and the 6.0 PSD is 30x21x2.25. One thing you should be aware of before you stat taking […]

Hunting For Horsepower by Alligator Performance

It was a busy Saturday. Trucks were lined up in the vacant lots behind Alligator Performance waiting to get dyno’d. This was Alligator Performance’s first event – and for a small, relatively new company, this was a big event. Alligator Diesel Performance opened their doors in Las Vegas in 2005. In 2009, they moved to […]

Fuel Filter Usage

Here’s a photo showing the condition of my original fuel filter after 24,000 miles – never been changed to this point since new: The photo is a bit misleading the overall condition of the old filter is actually not bad at all – lots whiter down in between the pleats than can be seen here, […]

Two Wheel Drive Low

The important thing is the 2 port vacuum switch…you need to get one that is ‘open’ when it’s in the off position so vacuum can flow through normally. I used a Nippondenso EGR vacuum switch for a Honda Civic. They never break! The rest of the parts list is simple and small: Rocker switch (I […]
