Turbochargers has to be overhauled after certain period of time. In this article we are going to discuss about the detailed dismantling procedure of a diesel turbocharger for overhauling and repair and for inspection in case of any abnormalities in the turbocharger operation. Also we discussed the tools required and safety precaution to be taken while dismantling a marine turbocharger. IHI Compact Excavator Sales, LLC. Download Workshop Manuals for Fords, Jaguars, Volvos & More. Workshop manuals are a series of practical repair manuals and service manuals, which are the same essential industry standard software as used by the dealerships around the world, covering repairs, service schedules, maintenance, wiring diagrams and diagnostics. Workshop manuals provide repair and service procedures for many. Refer to engine manufacturer’s manual and repair as required: Excessive dirt build-up on impeller and/or diffuser vanes Clean in accordance with the appropriate manufacturer repair manual: Turbocharger damaged Find and correct cause of failure, repair or replace turbocharger as necessary: Failed diaphragm Replace using correct Actuator. Service prices start at $375 for Journal Bearing and $450 for Ball Bearing. Actual cost of repair depends on extent of damage and type of turbocharger. High Performance Turbo Rebuild (includes balance) - This includes a steel 360 degree thrust bearing instead of the 270 degree and stepped gap piston ring if available for your turbo.
Usage notes:
This product is intended to be used only on racing vehicles on closed courses, and not for use on roads or vehicles otherwise subject to emission control requirements. Please check legality of aftermarket products with your country, local state, county, city authorities before purchasing. In USA, this product should not be used on any vehicles that is registered or licensed for use on public roads.
This turbocharger can be used as a trustworthy heavy-duty stock replacement , or for competitions with modifications of engine and peripheral accessories.
PRODUCT FEATURES
Compressor system has the high efficient function 'Abradable seal' and 'Larger impeller'. It will make stable & more compressed air to feed.
And 'Twin scroll type' turbine housing is same as mass production, so it can support a wide range of engine speed.
Wastegate actuator could be adjusted with using 'turnbuckle adjuster'.
. LeFever guns numbered under 10000 are built by the old LeFever Arms Company located in Syracuse NY. This company went out of business around 1915.In 1941 the company reserved blocks of serial numbers for Solid Rib, Skeet and Trap models. The initial sequence of numbers for the Solid Rib was 70000 to 79999. Serial numbers nero. In the fall of 1928, Folsom Baker magazine ads listed a 410 bore Batavia Leader, but it is unclear if any were actually manufactured. Folsom era Bakers usually have an F before or after the serial numbers 1- about 14,000. Most guns have a reinforcing wedge between the forearm loop and the flats.

ADJUSTMENT
1. Actuator
If the turbocharger unit which you select has the adjustable turn-buckle actuator, please use precise boost gauge and assure to fasten the nuts of the turn-buckle function when adjust it.2. Boost pressure control
To control boost pressure, aftermarket boost controller is necessary separately.In case of racing use:
If actual boost pressure will be increased much enough, although using boost controller, it caused by exhaust gas flow volume is exceeding wastegate capacity, and must keep back pressure with using smaller size exhaust pipes or must prepare additional wastegate function to fix it.
3. Engine control parameters
If the car is recommended to use regular gasoline originally, please feed premium gasoline when adjust ignition timing and so on to avoid engine blow caused by knock.NOTE
- When attach this turbocharger, the car might be prohibited by car regulation depends on peripheral modification spec.
