Another Pyrometer Installation

A. THERMOCOUPLE INSTALLATION – The R650 Thermocouple mounts into a 1/4″ pipe thread. If the exhaust manifold is already drilled and tapped, install the thermocouple at that location. If none is provided, make a 3/4″ hole in the exhaust pipe, not more than 6″ below the exhaust-manifold-to-exhaust-pipe connection and weld the R680 bushing into the […]

Repair Under Hood Weatherstripping

Tired of always finding the weather strip laying on top of the turbocharger in the engine compartment? A bead of silicone rubber RTV in the weatherstrip groove will keep the strip attached and eliminate the fire danger. Red RTV or high strength gray RTV is my favorite for this type of work. Black RTV would […]

Exhaust Stacks

I built this setup from scratch and ran it for only 1 month before removing and reinstalling my 4″ system. This system sounded very good but had some draw backs that I couldn’t live with including noise and smoke for passengers in the back and soot showers on startup after a rain or carwash (there […]

Relocating Your Block Heater Cord

As you know the block heater plug on our trucks are located in the front bumper and this is where they stay for most people. Some have put a plug recessed into the bumper to make it look nicer then having a cord dangling there. In my case being a Firefighter the way I park […]

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 […]

Port and Polishing

First, you will need cutters. In the next photo you will see some of the cutters I use for this. On the right are metal cutters. These cost $20 to $75 each, so choose wisely. In the middle are sanding cones. I use #80-100-220-240 grit. I use a long mandrel and a (not shown) short […]

Rim Fit

I used fellow TDR member JPittinger’s advice and did the following: Jack up the vehicle, take off rear tires/rims, install 2 lug nuts to hold the drum on. Start the truck, put it in 1st and low range of the transfer case – this makes the drums turn REAL SLOW. If you have an auto, […]

NXD Stacker Nitrous System

SO you're on the fence about the whole Nitrous issue. Well what if there was a product out there that was mild enough for the daily driver, wouldn't break the bank to purchase and easy enough even the most novice shade tree mechanic could install it? Well here ya go – The guys at Nitrous […]

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 […]

Cummins 12V Idle Adjustment Q&A

Subject: [RTML] Cummins idle speed How do I adjust the idle speed on my Ram diesel? The idle speed seems too high. First, trace the accelerator linkage to the connection on the fuel pump. With the ENGINE OFF have someone floor the accelerator and watch the fuel arm move. The best position I can describe […]
