Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM.
Propel parts is a good Cat vendor that provides a top notch service to customers from ordering to delivery. Their after sales service is really impressive.
Product Questions
Frequently Asked Questions
What is the 4W4146 cylinder liner used for?
The 4W4146 is a liner/sleeve that creates the running surface for the piston and helps manage heat, making it critical to engine compression and durability.
How do I install the 4W4146 cylinder liner?
To install the 4W4146 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut down, cool, and follow engine service procedures
- Remove the old liner and clean the block bore
- Inspect the bore, counterbore, and seal areas
- Fit the 4W4146 with new seals and the correct protrusion
- Verify protrusion and seating before completing assembly
Which Caterpillar machines is the 4W4146 compatible with?
Fitment for the 4W4146 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Or reach out to Propel Parts for help verifying fitment.
Does the 4W4146 cylinder liner meet performance standards?
Yes. The 4W4146 is manufactured to meet OEM specifications for tolerance and material quality. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications for dependable, long-term performance.
How often should the 4W4146 be replaced?
Plan to replace the 4W4146 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. When servicing this area, the 4200652 Seal Water is commonly replaced at the same time.
What are the signs of a worn or failing 4W4146 cylinder liner?
A worn 4W4146 usually gives early warning through the assembly it supports. Watch for these signs:
- Coolant or oil leaks around the liner
- Loss of compression or blow-by
- Scoring or excessive bore wear
- Cavitation pitting on the liner wall
Why is the 4W4146 cylinder liner important, and what related part is commonly replaced with it?
A sound 4W4146 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 1979257 Ring Intermediate is frequently replaced alongside this part.
