Knife Section and Guard Candidates for One Combine Header
RELIA reviews knife sections and guards as a matched cutterbar set, so working clearance and mounting fit are approved together.
For a cutterbar replacement enquiry, we can begin with our knife sections and knife guards. A matching pair requires your header reference and dimensions. These two links alone do not form an approved set.
This is a repair of an existing header. Start with the old section and guard, their mounting references and the observed failure. You are choosing a compatible replacement pair. We can shortlist catalog forms against those references, while your assembled trial decides whether both parts belong on the repair order.
One Repair Has Two Interacting Parts
An intact mate may allow one replacement. An incompatible or worn pair needs both references reviewed together. The old assembly, travel clearance and fastener positions tell us which buying scope is useful.
The Existing Header Provides the Best Reference
Send the old section and guard numbers when you have them. If a mark is unreadable, photograph both mounting areas and measure each part before searching for substitutes.
Keep the combine and header variant with those measurements. This repair record helps you judge a replacement pair in the existing cutterbar.
Section Holes and Guard Mounting Need Separate Checks
Keep both sets of measurements tied to the same header drawing or physical assembly. Our harvester dimensions guide supports that comparison. Check the knife-guard range against the old guard mount while you measure section holes separately; neither catalog name proves the pair fits.
Movement Matters After Static Fit
A repair-shop trial should check clearance along the section's travel, not merely bolt the parts in place. Record rubbing, interference and alignment with neighboring components. That observation gives your team a stronger basis for selecting the pair. The cutting-part selection guide can help you keep movement and clearance checks attached to this header, instead of buying two parts by name.
Replacement Scope Depends on the Damage
You may only need one family if the other remains serviceable and technically matched. If both are worn or distorted, review them together.
The Knife Section and Guard Are Approved as a Working Pair
For your cutting part, we keep the machine reference, mating geometry, wear requirement and field-fit result connected from matching through repeat supply.
Approve the knife section and guard as two controlled parts connected by one header fit check. The quotation should identify the source, quantity and timing for both items.
RELIA manufactures harvester cutting parts in its own factory. The range includes knife sections, guards, chopper blades and knife bars, with more than 300 compatible SKUs, 50–100 common SKUs available for quick supply and 800,000–1,200,000 knife-type pieces of monthly capacity.
The approved part reference controls production, and fit, dimensions, material and hardness checks follow the selected cutting part.
Before release, keep the machine or part reference, sample result, quotation and inspection record together so the cutting part remains traceable. Review the company profile or request the current ISO certificate copies.
A Repeat Repair Needs Part Identification
Once your shop approves a pair, record it against the header and keep each component separately identifiable. Similar-looking guards or sections may belong to different assemblies. Clear references help your mechanics and purchasing team avoid a wrong substitution next season.
Send Both Old Parts or Their References
Send the combine and header model, section and guard numbers, photos, measurements and required quantities. Note whether the goal is one repair or recurring service stock. Share these details with us for a reviewable paired shortlist.
