ELEMENT AS 4420103 - Caterpillar

Replacement crankshafts are shipped from the Caterpillar Inc. Parts Department using either one of the two methods that follow:Method No. 1:
* The shipping crate is lined with VCI paper, the crankshaft is coated with a rust preventative and wrapped with clear polyethylene.Method No. 2:
* The shipping crate has a crankshaft, without any rust preventative, sealed inside a VCI clear polyethylene bag. This sealed bag should not be opened until the cylinder block is cleaned, and the crankshaft is ready for installation.All crankshafts are shipped in a wooden crate with supports that protect the crankshaft and keep it from moving around inside the crate.If the crankshaft is shipped using Method No. 1, the crankshaft must be processed using all of the procedures given in this guideline with regard to unpacking, cleaning, inspection and plug installation before the crankshaft is installed in the cylinder block.If the crankshaft is shipped using Method No. 2, it will be necessary to clean the bearing journal surfaces on the crankshaft before the crankshaft can be installed in the cylinder block.The threaded plugs are already installed in the threaded holes at the opening of the drilled oil passages. Remove all plastic plugs from the crankshaft oil passages before crankshaft installation. Put a coat of clean engine oil on all crankshaft surfaces before the crankshaft is installed in the cylinder block.1. Remove only enough of the support blocking from inside the crate to allow the crankshaft to be lifted "straight up".
To prevent damage to the crankshaft, do not turn the crankshaft while it is in the crate.
2. Remove the protective cover from two of the connecting rod journals that are facing "UP".Fold a clean chamois, thick cloth, or sheep hide (with the fleece side toward the journal) around the two connecting rod journals, as shown. This will prevent any damage to the bearing journal surfaces. 3. Use nylon straps and a hoist to remove the crankshaft from the shipping crate.
When the crankshaft is in storage, always protect it with a clean canvas or polyethylene cover.
Crankshaft Cleaning
Always wear protective clothing and eye protection when removing and installing crankshaft plugs, cleaning oil passages with a brush and electric drill, pressure air, or, when using the cleaning gun with the hot cleaning solution. Sludge, metal chips and/or other foreign material that is forced from the oil passages under pressure can cause injury if proper protective measures are not used.
For those replacement crankshafts shipped from Caterpillar with a coating of rust preventative, the 7W1632 Plugs are in a package in the crate.All external and internal surfaces of the crankshaft must be completely cleaned, and the 7W1632 Plugs for the oil passages must be installed and tightened to the specified torque, before the crankshaft is installed in a cylinder block.
Jumbo Jiffy Gun with Air Boost.For thorough cleaning, a nozzle with a high aerated flow or pulsing flow is recommended. One aerated nozzle that can be used for cleaning crankshaft passages is the "Jumbo Jiffy Gun" with "Air Boost" from the Elliot
