Unimog 1300L引擎的改造
第一期(一):
Unimog 1300L Engine Rebuild/Replacement
The Experience These photos were "lost" for quite awhile until I found them under the wrong folder on the computer. My 1300L Unimog suffered an engine failure and these photos describe the removal of the motor and installation of a brand-new crate motor from Mercedes-Benz in Germany. This effort was big and spanned about 6 months all told. The failure happened in December 1998 and the truck was finally ready to roll the last day of May 1999.
The photos below are what we saw.
The head was taken off the motor while the block was still in the truck. The shot above was taken from underneath the head as it was hanging from the engine hoist.
The head is a beefy chunk of meat. I would hate to have it fall on my foot.
The truck frame, sans engine.
Houston, we have a problem. Note that the #5 and #6 cylinders have deep scars. If you look closely, you can see the crack in the #5 cylinder (the one toward the bottom of the photo) that is in the web between the cylinders. This means either the block needs to be replaced or it needs to be re-sleeved. I opted for a new block.
Kai pulled the engine out. Above, Kathleen inspects the inside of the cylinders.
Kai examines the head. Note the valve cover on the bench at the bottom of the photo.
The ass-end of the motor was dripping oil through the rear main seal. Not a good sign. But, since the block is going to be replaced anyway, it is just making a mess.
The clutch, too, has seen its better days. Soon, it will be off to the shop to be re-done as well.
Note the oil in the bell housing and the scars on the flywheel.
We waited from December to May to get the full set of parts and the correct block as a earlier model, non-turbocharger rated block was first shipped. Note the part number below the machined surface for the air pump.
This is the block after it was first uncrated and unwrapped.
We had the old head inspected and found some cracks which required a new head and the gasket kit as well.
To protect the new motor, a pre-luber was also installed.
The turbocharger was removed and re-built.
The old water pump was deemed serviceable and was therefore used in the new installation.
The turbocharger-rated block has pistons with depressions in the center to improve efficiency.
The piston for the air compressor fits to the cam shaft.
The original equipment belt-driven air compressor was one of the first things to fail on my truck and had been replaced with a cam-actuated, block mounted compressor.
The new head looked nice and clean before the injectors and associated plumbing was installed.
The head is mounted on the block.1
