Unicorn 12V Cummins Dodge Returns - Intermittent Missing, Dying - Area Diesel Services Saves the Day

The 1995 Dodge Ram 2500 we dubbed "The Unicorn" is back. It has an issue missing and dying but only when it's really hot. We pull the Bosch P Pump and have it repaired by Area Diesel Service.

Hello Wes, Bosch had a service bulletin on these pumps back in the late 90s. Excess assembly lube on the lower barrel o-rings at the factory in Brazil where these pumps were built would cause the plunger to stick or hang in the barrel when hot. The heat would cause the lube to expand that was captured between the lower o-rings, constricting barrel and binding plunger. The cure is teardown and reseal barrel assemblies.

[@WatchWesWork]

Area Diesel sent me the bulletin and they seem to think that was the issue.

Would this be considered a form of hydrolocking the plunger? Hope you had a good Thanksgiving Wes.

[@markmackenzie2533]

Hi Wes, I came to you via Diesel Creek and Area Diesel Service. I've seen the full repair of the Bosch diesel pump, literally hours and hours of watching the assembly and calibration of the pump. Such an amazing series of videos. What a pleasure to see such truly skilled professionals display their skills and craft. Be very proud, all of you, as you are the men and woman who make America great. Greetings from Australia. There are several points in your videos that surprise me. The most notable is the fact that most vehicles are not inspected for registration. In New South Wales all vehicles are inspected for registration once they are more than five years old at every annual registration renewal thereafter. All of those rusty wrecks you show with chassis and structural rust wouldn't be registered in Australia. Part of the road test includes a test to prove the hand brake functions. Along with a readout from deceleration meter to prove the function of the handbrake. So far they don't test for exhaust emissions, although smoky diesels would need to be checked and repaired. Luckily we don't have salted roads in Australia. Vehicles can easily last thirty years when properly maintained and driven. Thank you for a great KZbin channel

I encourage everyone who wants to know how difficult it is to do some of these jobs, (But Gary made it look super easy), to watch the full length of all three videos in that same order.

[@bostedtap8399]

That pump is nearly as big as the engine in my first car ( Austin Mini 850 cc). The close tolerances are mind blowing on these instruments, hence part of the cost of diesel engines being expensive compared to petrol equivalents. Great diagnosis and repair, thank you for sharing. Regards John

LOL). I'm sure the price for this was high ... just remind the Customer he/she's paying for Gary's 4 decades of Experience, not just the actual hands on labor hours !!! Enjoyed the jaunt Wes !

All I can say is the people near you are lucky to have you. Your knowledge, your dedication to getting it right is top notch. If I lived near you I would definitely use you for my repairs. Unfortunately, as I have gotten older, there are things I no longer do. Having to rely on others to do what I used is hard. Thankfully, I believe I found someone good near me but only after finding a dud first . Keep up the good work and these great videos.
