Did he make the 1992 D2 bulldozer costing $500 run

 Thats 33 years old.  The tracks were stuck and the only thing he said that was working was the engine  

And for $500.00 for a running CAT engine, he said the amount was worth it.  Yes he was able to make this run after checking the fuel, and making sure that fuel reaches the injector.   And he was made able to unstuck the tracks.  How amazing.!





Repairs are getting more expensive; it is easier to repair older engines but not the modern, electronically controlled ones

 Matt of Diesel Creek shows how simple and straightforward the repairs of mechanical engine  Those that are all ready electronically controlled looks complicated and expensive to repair.

Most of the engines of Heavy Equipment repaired by Matt are diesel.  The electric part only is about battery and starter.   That is all.    (The only complicated ones are bulldozers that have pony engine.  First you have to start the pony engine and then the pony engine will start the main diesel engine)  Then it is a straighforward checking and replacing oil, fuel, oil and fuel filter.   That is it.

But  there are two main paths to pursue in electonically controlled engine:   fuel (which is also electonically controlled by ECU fuel injectors and sensors)  EGR valve, crankshaft position sensor.   And they are not cheap

Thus Matz had to resort palit (change) parts (no more repairs) that involve sensor, ECU (which cost 6 numbers) And a day repair by Matz can cost upwards from P5K to P100k.    That is not my type of repair.

Our Navarra pick up repair tab runs up by 6 numbers too.  Huhuhu

Repair from Matz Mechanic

 I have watched his video from FB.

I noticed this Visayan speaking mechanic from Oroquieta:

1.  Most of defective vehicles are from Ford;

2.  He speaks in Visiayan

3.  He does this scientifically using a computer;

4.  He sells both his parts and service (which sounds pricey)   He changes modules rather than repair of individual parts.    

He does excellent repair but it looks expensive.   He has been expanding as many as far as Basilan and Zamboanga, and from Cebu goes to him for repairs

But his analytical skills are tops.





Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
