Clark 4500HP 12 Cyliner Engine Piston and Liner Replacement

Just got back from working on a 4500HP Clark 2 cycle, 12 Cylinder Natural Gas Fired Engine/Compressor Unit. We had to change out a couple cylinder liners, Pistons, Rods ect.

I took a few pictures to share in case anyone else likes large industrial engines.




Here's one of the Units, My co-worker standing in front of the cylinder heads taking some pics. You can see the three compressors that the 12 cylinder engine drives. The reciprocating motion of the crankshaft is transformed via cross heads into linear motion to drive the compressors. These compressors compress natural gas.




Taken from the top of the cat walk from one of the units, looking at the Unit that's being worked on.




Cylinder heads. 6 Cylinders on each side. You can see the air intake manifolds for both banks.




Here's a shot of my ugly mug...




Here you can see the oil cooler along with some of the coolant/oil lines. This unit is massive!




Here Dean is standing in front of the mechanical oil pump, look at the size of the block on this bad boy




Here I'm standing in between two of the three double acting compressors that the engine drives. You can really see how big they are in this shot. On the ground you can see a cylinder head in the bottom left corner of the pic.




Here I'm standing next to a new chrome cylinder liner, we just finished prepping this liner for install.




Installing the new liner.




Looking into the block. You can see the intake and exhaust ports. A co-worker is cleaning inside the crank case, gives a good reference to the size of the crank.




Piston with the Master Rod attached.




Piston with the Link Rod attached. Only the master rod attaches to the crank shaft, the opposite link rod attaches directly to the master rod via a link pin.




Here the piston crown is separated from the skirt. The pistons are a 3 piece unit. Look at the size of the crank pin bearings!




New parts getting ready to be assembled. Master Rod with Hanger, Link Rod, Link Pin, Piston Pin ect.

Oh man...that is just way too wicked! Now THAT'S an engine!

Cool pics.
You guys gonna' throw on some spannie chambers and do some porting? :)

What does one of those pistons & rods weigh? That's a big slug.

Not sure of the weight on the piston for this unit, I could look it up back at work though. Our smallest engines (IR KVS) have pistons that weight 400lbs bare.

Here's a picture of a KVS piston next to my old XRR




I ended up making that piston into a vise stand for the garage.

Holy crap...that vice ain't no slouch either!

Hodaka - Don't go through the trouble to look up exact weight. You've given me the gist. Thanks.

Very Cool

So are you a contractor or Pipeline worker?
I work at a Gas Pipeline Station (9 years) and we are a total Clark station. 59,900 hp total. We have 9 HBAT-8 Clarks (inline 8 cyl), 6 Clark TLA-6 (inline 6 cyl), 2 Clark TVC 12 (V12) and 1 Clark TCV 16 (V16). Also have a 7500hp Cat Centaur Turbine and a Cat 15,000hp Mars Turbine.
I need to send you a picture of our TCV cylinder lifting tool that we made that keeps the hoist block out of the cylinder.
Are your engines HPFI?

Yep I'm a Gas Pipeline Worker also You have a TON! of HP there. How many people take care of the units?

Hodakaguy

We got 24 people but by time you figure in Automation, R.O.W., code work, construction, weekly checks, operator duties and PTO we have about 7 at any time mainting equipment. It does not take long for our crew to thin out. Tiring at times but we get the job done.

Nice!
