Liner Fit Questions
Ask us when a liner profile or seating looks wrong, before you cut anything.
Common liner fit questions and practical answers
When fitting new jaw plates, mantles, concaves or other wear parts, it is common to notice that a profile does not seem to seat properly or leaves gaps on the contact faces. This could be due to an incorrect profile for your closed side setting, excessive paint or corrosion build-up on the seating surface, incorrect liner orientation or even issues with previous weld repairs. Before reaching for the gas torch or grinder, always check the part number and profile against your crusher’s requirements.
Incorrectly seated liners can lead to premature loosening, uneven nip angles, poor crushing chamber performance and even dangerous movement under load. It is essential to inspect the liner seating area for old backing compound, high spots or debris, and to confirm that all lifting lugs and fixing holes line up per OEM recommendations. If you are unsure, rather pause and consult before attempting any modifications.
What to send us for liner fit support
If you are facing a liner fit problem, we can help you quickly if you send clear information. This allows us to match the correct profile or spot any issues without unnecessary trial and error or risky field modifications.
- Photos of the liner and seating area from multiple angles
- Crusher model, serial number and chamber profile
- Part number marked on the liner
- Any measurement of gaps (use a ruler or feeler gauge if possible)
- Describe where the fit is off (top, sides, rear, bolt holes, etc)
What happens after you email us
Once you email all the relevant details and images through our contact form, our technical team in Germiston reviews the information. Usually, one of our experienced parts specialists will reply within the same working day, or on Monday if you email late Friday. If needed, we consult with our yard team or OEM engineers to verify correct part numbers, seating geometry or any modifications seen.
We will recommend next steps, such as re-cleaning the seat, checking liner orientation, or arranging an exchange if a profile issue is confirmed. In some cases, we may suggest bringing the liner to one of our showrooms for hands-on assessment, or providing torque specs from the OEM manual. Our priority is to keep your bakkie or crusher running safely, and avoid costly mistakes from hasty field mods.
