Ford Mazda MZR 2.3 engines found in: Mazdaspeed 3 6 / Turbo / CX-7 DISI Direct Injected Injection Axela A true cut above in quality and accuracy! You'll need these tools to positively hold your crank and cams in place whilst timing your motor. No other mfg offers the level of precision found here. This high quality kit features both the cam lock gage, and crank stop TDC pin. Using both of these will allow you to be 100% certain your cam install results in proper timing - failing to do so can have very disastrous results - bent valves, smashed pistons, etc. Gages are much more than a simple piece of bar stock like others have produced - they are much thicker (and hence stronger) bars that feature 2 machined reliefs offering a TIGHT +/- .001" fit. A much more accurate means of locking your cams, resulting in less need for cam degreeing post install. Pins are super tolerance monolithic machined 6061 aluminum for an exact fit. Pins are anodized in high vis Massive Purple for corrosion resistance, and this bright coloring will help to remind user of removal (seen folks leave it in - NOT good!). Should pin be left in, aluminum construction will give way without harming vital engine internals. Handle area has built in hex for tool usage. Great for service on the faulty / problematic VVT gear / ticking and loose chain issue on 07-10 MS3 and CX-7. Mazda Bulletin / TSB / Recall No:01-012-12 Quality made IN HOUSE right here in the USA!!!
