Installing a new clutch is an exercise in frustration, mainly because you have to manhandle a giant transmission underneath your car. The last thing you want to do is have to start all over because the clutch plate slipped out of alignment and won't engage with the input shaft. Save yourself some time and effort and use a clutch alignment tool to make sure this does not happen to you. The tools are very simple, made from injection moulded plastic or nylon, you need the tool that matches your transmission. This is a matter of knowing the spline count on the input shaft. If the splines don't line up, it won't work. Do not try to fudge it with a tool that does not fully engage the spines. If your clutch alignment tool does not fit the pilot bearing/bushing, it is the wrong one, you need to get the correct one. On the back of the engine, the flywheel bolts to the crank. Inside the crank is a recess for the bearing. The tip of the clutch alignment tool locks into the bearing, keeping your clutch in place. First, insert the tool into the clutch plate. Make sure the clutch is facing the correct direction. The tool should stick all the way through the spines on the plate. Then place the clutch on the flywheel, and engage the alignment tool into the pilot bushing or bearing in the centre of the crankshaft. Push the clutch tight to the flywheel. The tool goes into the clutch plate, and then the tool is installed into the bearing on the flywheel. It should not move around at all. With the clutch on the flywheel, install the pressure plate to the flywheel and start the bolts. Wiggle the alignment tool to make sure it is fully engaged and seated in the pilot bushing/bearing. Tighten the pressure plate bolts in a criss-cross pattern and then torque to spec. The clutch alignment tool stays in the clutch until you are ready to install the transmission. While the pressure place should hold the clutch from moving, don't take the risk of pulling the tool out too soon. Once the transmission is ready to install, pop the tool out, and slide the transmission into place. Every application has a different clutch tool. These three tools look similar, and may even mesh together, but they are all different.Features and SpecificationsClutch Industries (CI) Clutch Alignment ToolMandatory use on Clutch InstallsEnsure optimum clutch life and performanceDual Mass Flywheel: Not IncludedConcentric Slave Cylinder: Not IncludedFitment:Isuzu Elf 250 Series 4.6 Ltr, 4HG1 NKR71, 1/95-12/01, New Zealand Model 1995-2001Isuzu NKR Series 3.6 Ltr, 4BE1 NKR58, 5/90-4/98 1990-1998Isuzu NKR Series 4.3 Ltr, 4HF1, 85kw NKR66, 7/91-9/94 1991-1994Isuzu NKR Series 4.3 Ltr, 4HF1, 85kw NKR66, 10/94-12/02 1994-2002Isuzu NKR Series 4.8 Ltr, 4HL1 NKR81, 1/02-12/08, New Zealand Model 2002-2008Isuzu NPR Series 3.6 Ltr, 4BE1 NPR58, 5/90-4/98 1990-1998Isuzu NPR Series 4.3 Ltr, 4HF1 NPR66, 7/91-9/94 1991-1994Isuzu NPR Series 4.3 Ltr, 4HF1 NPR66, 10/94-12/06 1994-2006Isuzu NPR Series 4.7 Ltr TDI, 4HE1T NPR70, 5 Speed, 1/00-10/02 2000-2002Isuzu NPR Series 4.6 Ltr TDI, 4HG1-T NPR71, 1/00-12/03 2000-2003Isuzu NPR Series 4.6 Ltr TDI, 4HG1, 85kw NPR71, 4/98-9/00 1998-2000Isuzu NPR Series 4.3 Ltr, 4HG1 NPR77, 3/95- 1995Isuzu NPR Series 4.3 Ltr, 4HF1 NPR77, 3/95- 1995Isuzu NPS Series 4.3 Ltr, 4HF1 NPS66, 6/93-12/98 1993-1998Isuzu NPS Series 4.6 Ltr, 4HG1 NPS71, 1/98-8/05 1998-2005Isuzu NPS Series 4.6 Ltr, 85kw NPS72, 1/00-12/07 2000-2007Isuzu NPR250 4.6 Ltr Diesel, 4HG1, 85kw NPR71, 7/94-4/98 1994-1998Isuzu NPR250 4.6 Ltr Diesel, 4HG1, 85kw NPR71, 4/98-1/03 1998-2003Isuzu NPR250 4.6 Ltr Tdi, 4HG1-T, 89kw NPR71, 8/00-1/03 2000-2003Isuzu NPR300 4.6 Ltr Diesel, 4HG1, 85kw NPR71, 1/98-12/03 1998-2003Isuzu NPR300 4.6 Ltr Tdi, 4HG1-T, 89kw NPR71, 1/00-12/03 2000-2003Isuzu NPR400 4.6 Ltr Diesel, 4HG1, 85kw NPR71, 1/98-12/03 1998-2003Isuzu NPR450 4.6 Ltr Diesel, 4HG1, 85kw NPR71, 1/98-12/03 1998-2003Isuzu NPR400 4.8 Ltr Tdi, 4HE1-XN, 103kw NPR70, 1/00-11/02 2000-2002
