As with most any Toro Genuine Part, Toro seals are designed for a specific application for retaining lubricants and fluids and protecting against debris and moisture that can damage tires, gears or motor components. The best way to assure that you are replacing worn-out seals properly is to order Genuine Toro Seals.
Questions for you to think about are:
- How do you know the will-fit bearings seals have been purchased from a trustworthy manufacturer?
- Do you have the confidence in the seals once installed on your Toro machine?
- Are you getting the exact, high-quality seal designed specifically for the application?
It's hard to know what your getting with a will-fitter replacement seal. It comes down to buying more than just a seal from Toro, it's a matter of buying confidence as well. Keep in mind, will-fitters are always looking to cut corners with replacement parts. And Toro is always looking to meet or exceed our standards to make sure your customer's Toro product will remain on the job day after day.
As with all our parts, Toro conducts continuous and extensive seal tests to assure they will not fail for specific applications and mechanisms.
Here are the key points about Genuine Toro Seals:
Toro seals are designed for specific applications. Too tight of seal can cause extra drag on the roller, tire, or moving part and can drain horsepower from the engine. A tight seal could also cause undesirable mowing efficiency as well.
A seal that is too loose will allow fluids and lubricants to leak from the component and cause damage to the turf. Moisture and debris can also get into the housing and cause premature wear and damage any moving components.
Oil Seal Installation Recommendations
- Check Dimensions to be sure that shaft and bore diameters match those specified for the selected seal.
- Check Seal for damage that may have occurred prior to installation. A sealing lip that is turned back, cut or otherwise damaged should be replaced.
- Check Bore to see that the leading edge is deburred. A rounded corner or chamfer should be provided.
- Check Shaft and remove nicks, burrs and grooves and look for spiral machine marks that can damage the seal lip.
- Check Shaft End and remove burrs and sharp edges. In the event the seal installation requires that the shaft enters the seal against the sealing lip, the shaft end should be chamfered.
- Check Seal Direction making sure that the new seal faces in the same direction as the original. Generally the lip faces the lubricant or fluid to be sealed.
- Prelubricate the Sealing Element before installation by wiping with the lubricant being retained.
- Use Correct Installation Tool Press fitting tools should have an outside diameter .010" smaller than the bore size. If possible, the center of the tool should be relieved so that pressure is applied only at the outside diameter.
Never Hammer Directly On The Surface Of The Seal
- Use Proper Driving Force where possible such as an arbor press; otherwise a dead blow hammer can be used to avoid popping the spring out of the seal. CR rawhide mallets are ideal for this purpose.
- Bottom Out the Tool or Seal to avoid cocking off the seal in the bore. This also positions the seal correctly on the shaft.
- Check for Part Interference from other machine parts that might rub against the seal to cause friction and damaging heat.
