Hydraulic cylinder repair by Matt at Diesel Creek

Matt showed how to repair the hydraulic cyclinders of D4 Komatsu bulldozer. He had deferred such repair for 5 years, although it cost him much in terms of lost hydraulic fluid that leaked.

As usual, it is demonstrated that disassembly was mostly hard and challenging.  He improvised:

     1.  How to remove the cylinder cover by welding a flatbar which he hammered;

     2.  Pulling out the internal rod by using a back hoe.

The seals and glands were bought from the store and Matt reinstalled them well.  

Rey Guiab, Dirt Mechanic - alis lagutok ng steering - kulang sa grasa

 Mr. Guiab shows how to DIY remove the lagutok of the rack and pinion steering.   Nothing was wrong mechanically.  Just that the interior were dry and no grease.   Easy to do removal.   Remove 4 bolts, tie rod end.   Remove 2 bolts at the top from the column. 

Remove the boot, remove the pinion and the guide.  Inspect the rack and pinion.  The difficult part are the lock ring removal and replacement

Spark plug replacement of Subaru Forester

They say this is next to impossible, one of the most difficult repair job in a Subaru.  Some say you need to remove the engine.  But some say it is easy.   

At the driver side, remove the battery.  At the battery side, remove the air intake.

Then remove the coil, and then insert the 14 mm spark plug removal tool.  The spark plug should go with  the spark plug socket removal tool.

I hope it is easy.  I have not replaced the spark plug of the subaru.   (There is a subaru spark plug and aftermarket)

Replacing Subaru lens, lens removal and assembly

 These parts are pricey.   The lens alone would set you back by P3,000+ and the whole assembly by P40,000.   

I got interested in this because water entered the headlight assembly of the subaru forester we had.   You have to find the tabs, remove the front grille and bumper, then you can remove the headlight assembly.

To remove the lens from the plastic body you can do:   1.   use a blowtorch (or hair blower) to soften the plastic   2   invent an oven (a box where you blow in the hot air for 15-30 minutes.

Carefully remove the plastic, clean the interior and polish.   You should watch the Pakistani craftsmen do this the lens cleaning

Subaru Forester rear bearing assembly removal

 This would seem to be a favorite topic, being one of the most difficult task for the said vehicle.   You may need a hammer removal tool, and fabricate a pusher type of tool to remove the assembly from the hub.  More power

We happen to own a Subaru Forester, that is why this is an interesting repair topic
