Gone are the days when the only solution to crankshaft wear is either to replace the crankshaft or remachine its surface. With the crankshaft repair sleeve, you now have a way to smoothen out the crankshaft’s sealing surface. Because proper crankshaft seal can be achieved, oil leak in the grooves or seal wear track can be prevented.
If it’s now time for you to get a crankshaft sleeve, here are the factors you should consider to be able to find a unit that doesn’t just meet your needs but also offers the best value:
Size of crankshaft repair sleeve
The sleeve won’t be effective if it isn’t fitted snugly on the shaft. To get the right size of sleeve, you have to measure the diameter, not of the shaft, but the area where the sleeve will be installed, which is on the shaft’s unworn part. To be sure that the shaft is still within the recommended specs, you have to measure in three different positions and get the average of the three measurements you’ve gathered.
If the average is not exact but still falls within the range of a particular sleeve size, there’s no need for you to worry because the sleeve has enough press fit to keep it from spinning or sliding even without using an adhesive.
Ease of installation/removal
The crankshaft repair sleeve is basically installed using an installation tool, so you can just base your choice on how easy it is to remove when it’s time to replace it. Some sleeves can be taken out of the crankshaft by simply applying heat to the sleeve using an electric heat blower. Heat causes the sleeve to expand just enough to let it slide off the shaft without damaging it.
Other sleeves can be removed from the shaft by gently tapping the full width of the sleeve using a small hammer. Doing so will release the sleeve’s press-fit tension. You can also use a cold chisel or a pair of wire cutters to make a cut near the flange and apply a twisting motion until the sleeve is removed.
It is always wise to get a crankshaft repair sleeve that comes with good warranty coverage as it will protect you against factory defects that may just come up once the product has been in use. Crankshaft repair sleeves can be offered with the industry-standard 90-day warranty up to 1-year manufacturer limited warranty.
