Frequently Asked Questions
What is the 1987825 seal used for?
The 1987825 seal keeps fluids contained and contaminants out where two surfaces meet or a shaft rotates. A sound seal maintains pressure, prevents leaks, and protects the components it isolates.
How do I install the 1987825 seal?
To install the 1987825 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut down and depressurize the system, then let it cool if needed
- Remove the old seal and clean the bore and shaft surfaces
- Inspect the sealing surface for scoring, pitting, or wear
- Lightly lubricate the 1987825 as directed and fit it square to the bore
- Seat it to the correct depth without distorting the lip, then check for leaks
Which Caterpillar machines is the 1987825 compatible with?
The 1987825 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.
Does the 1987825 seal meet performance standards?
Yes. Propel Parts supplies the 1987825 as a premium aftermarket part made to meet OEM specifications. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so you can fit it with confidence.
How often should the 1987825 be replaced?
Replace the 1987825 whenever the assembly it serves is overhauled, or any time it shows wear, damage, or corrosion. Following the intervals in your service manual is the best guide. When servicing this area, the 0951622 Seal O-Ring is commonly replaced at the same time.
What are the signs of a worn or failing 1987825 seal?
A worn 1987825 usually gives early warning through the assembly it supports. Watch for these signs:
- Visible fluid leaks or seepage at the joint
- Loss of system pressure
- Contamination found inside the assembly
- A hardened, cracked, or torn sealing surface
Why is the 1987825 seal important, and what related part is commonly replaced with it?
A sound 1987825 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. During an overhaul, the 5L3378 Gasket is frequently replaced alongside this part.
