Feature

The Crankshaft Saver by Just Miata should be a part of every timing belt service performed on any first or second generation Mazda Miata.
The Crankshaft Saver by Just Miata is 1) life insurance for your Miata's healthy crankshaft and 2) the ultimate crankshaft repair kit for damaged Mazda Miata crankshafts.
Question: "What is wrong with all of the first and second generation Mazda Miata crankshafts. Answer: "The crankshaft snout is too short"
The Crankshaft Saver fills in the problematic 14mm air gap at the end of the Miata's crankshaft. This air gap of over 1/2 inch in length is the source of many problems that ultimately result in catastrophic crankshaft failure.
Crankshaft Saver will not only provide important life insurance for your healthy Miata crankshaft but Crankshaft Saver will repair any damaged Mazda Miata crankshaft keyway and crankshaft snout. CRANK SAVER DOES NOT ADDRESS THE 1990 SHORT NOSED CRANKSHAFT ISSUE. THERE HAVE BEEN TWO UNFAVORABLE REVIEWS DUE TO MIATA OWNERS NOT FAMILIAR WITH THIS CRANKSHAFT VARIATION. CRANK SAVER DOES NOT ADDRESS THE 1990 SHORT NOSES CRANKSHAFT ISSUE.

Product Description

We have designed and manufactured the Crankshaft Saver and have saved many of my customers Miata's engines by using my Crank Saver bushing and custom key.

Crankshaft Saver was designed so that it can also be disassembled. It is not permanent, there are no glues, no welding. Your front crankshaft seal can still be serviced at any time.

Crankshaft Saver is great life insurance for healthy crankshafts and ultimate repair kit for damaged ones. So the next time you're servicing the timing belt add the Crankshaft Saver to your parts list.

I strongly recommend that you purchase a new Timing Belt Sprocket and Pulley Boss to insure true surfaces and slots before assembly if you have key and keyway damage. If you are using the the Crankshaft Saver as life insurance for your crankshaft then there is no reason to replace the Timing Belt Sprocket or Pulley Boss. I will not guarantee satisfactory results if these two items are not replaced.
