What comes off the line
Nine Families of Replacement Seat Parts
Every part on this page comes off a seat we build.
Seat covers, armrests, seat belts, rail slides, suspension assemblies, pressure sensors and micro switches, swivel rotary consoles, lawn mower covers and spindle mandrel assemblies are the same items that go onto KL01, KL11, YY03 and YY53 forklift seats, KL02 and YS2-8 construction seats, KL03, YJ03 and YY08 agricultural seats and the YY70 mower seat, at the moment those seats are assembled. Ordering seat spare parts here is ordering the production item, not a look-alike matched out of a catalogue photograph.
One line covers the whole seat, so a counter already stocking our covers adds belts, slides and suspension assemblies without opening a second account.

Ordered against the seat, priced as a part
Parts run on their own minimums rather than on the seat minimums, so a stocking line can start at one part number.
Mixed orders travel on one confirmation
Seats and replacement seat parts on the same enquiry are quoted together and shipped on the same paperwork.
How the nine divide
Four Ways the Nine Families Divide
The nine divide four ways, by how they are bought rather than by what they are made of.
Group 02
Safety and interlock
Fitted new and never repaired in place. Nothing inside a retractor or a sealed switch is intended to be opened in the field.
- Seat belts · Pressure sensors · Micro switches
Group 03
Mounting and position
Work against the mounting face and against where the operator has to face. Both are decided by what is already on the machine.
- Rail slides · Swivel rotary consoles
Group 04
Assembly level
Supplied complete and matched to a seat model. The highest-value items in the range and the most tightly matched.
- Suspension assemblies · Spindle mandrel assemblies
Contact surfaces
Seat Covers, Mower Covers and Armrests
Seat covers are the item most parts counters open an account for.
PVC is the standard cover across the range. It wipes down after a shift of dust and wet boots, and it is what goes on KL11 as a hard-wearing waterproof black cover, on YY03 over high-density foam, on YY53 and on YS2-8. Fabric is available where the cab stays enclosed, and that choice is worth making per machine model rather than across a whole order.
A cover is ordered against the seat model, because cushion and backrest shapes differ across the range.
- KL02
- High-back seat with full-body and head support, for long shifts on heavy machines.
- YS2-8
- Backrest folds forward 27.5°, with 60 mm of height adjustment and adjustable armrests.
- KL11
- Low-back seat with no headrest, in hard-wearing waterproof black PVC.
Mower covers and armrests
A cover cut for one model does not sit correctly on another. Lawn mower covers are their own family because the YY70 is exposed to grass, rain and sun for its whole life. Armrests come off the same models: KL01 and KL11 carry flip-up armrests and YS2-8 adjustable ones, with the pivot on that model's backrest frame.
To order a cover or an armrest
Seat model, cover material and colour, quantity. Nothing else is needed here.
Marking and colour on volume
Both can be changed on volume orders through the OEM and private label programme.
The label on the seat decides the part. The plate on the machine does not.
Safety and interlock
Belts, Sensors and Presence Switches
These are the parts that stop a machine working rather than making it uncomfortable.
- Seat belts are supplied across the range, and the belt anchors onto the seat frame itself.
- So a replacement belt is matched against the seat model in the same way a cover is.
- YS2-8
- Ships from the factory with a retractable belt.
- KL11
- Takes a belt as an option, alongside the switch and the rail slide.
- KL01
- Can be built with an operator presence switch, and the same option runs on KL11.
Pressure sensors and micro switches are the operator presence circuit. When it goes dead the machine reads an empty seat and holds whatever it is interlocked to, and the workshop traces a machine standing still back to a component the size of a thumb.
Seat belts
Tell us whether the seat runs a retractable belt or a static one, and whether the anchor points are on the seat or on the machine.
Sensors and micro switches
Fitted items with no serviceable interior. A retractor and a sealed switch are replaced, not opened on the bench.
Send the connector photograph first
This is the one family where a photograph of the plug on the loom is worth more than the machine model. The connector decides which switch goes in the box, and it has to reach us before a sample is built.
Mounting and working position
Rail Slides and Swivel Consoles
Rail slides come to us as a parts order for two different reasons.
The first is wear: a slide that has taken grit for several seasons goes stiff, then jumps in its detents, then stops locking where the operator leaves it. The second is fitment: some machines carry rails on the mounting base already, and the seat is expected to sit on those rather than bring its own.
- KL01
- 165 mm of fore-and-aft travel.
- YS2-8
- 150 mm of fore-and-aft travel.
- YY01
- Half-suspension seat supplied with slides and fine backrest angle adjustment.
Swivel rotary consoles
For operators who spend part of the day turned towards an implement instead of facing forward. The console turns with the seat, so the controls stay where the operator's hand expects them at the angle the work is done at.
Worn slide
Stiff, jumping detents, or no longer locking. Replaced as a pair against the seat model.
Rails already fitted
The machine carries its own rails, so the seat sits on them rather than bringing slides.
Damaged console
Used as a step or a handhold until the rotary mechanism no longer holds an angle.
Upgraded position
A machine being given a working position it did not originally have.
Assembly level
Suspension and Spindle Mandrel Assemblies
A suspension assembly leaves here as one unit.
Frame, spring pack, damper and the weight adjustment mechanism, in the state it ships in under a finished seat. It is built against a seat model rather than against a machine: the scissor pivots and the upper mounting points are cut into that model's frame, so the assembly and the frame it goes back onto have to be the same model.
Stamping and welding sit in the same building as the assembly line, so the assembly ordered in the third year comes off the same tooling as the one that went out under the seat in the first.
Three checks before an assembly goes onto a frame that has already worked
The frame is the right model
An assembly built for another model will not sit square, however good the assembly is.
The operator falls inside the range
Weight adjustment is set at build. A driver outside that band rides on the end stops rather than on the spring.
The mounting holes are still round
A hole pulled oval by years of vibration will not hold a new assembly square, and that is the check that most often turns a part order into a seat order.
- 50–130 kg
- Weight adjustment range on YS2-8 and KL01, and on YJ03 with air suspension at 24 V.
- 40–120 kg
- Weight adjustment range on YY03 and YY53.
- 80 mm
- Suspension travel on YS2-8, the longest published figure in the range.
- 50 mm
- Suspension travel on KL01.
- 48 mm
- Suspension travel on YY53.
Travel decides the headroom left above the operator once the machine is closed up. Figures for the other models are confirmed against your seat model when you ask.
An assembly order needs three things
- The seat model it is going under.
- The operator weight range the machine works across, not one driver's weight.
- A photograph of the old assembly still in the frame with the seat tipped back.
That photograph shows the state of the scissor pivots and whether the upper mounting points have moved — the difference between an assembly that drops in and one that has to be forced square.
Held whole when a batch fails
Assemblies are tested as shipped on the fatigue bench in our own test centre. A batch that fails there is held whole and traced back to the welding station or the damper lot behind it, and it stays held until a retest passes.
Spindle mandrel assemblies
Supplied on the same principle: complete, matched to the platform they were built for. Bearings, shaft and housing are set against each other at build, so an assembly ordered whole arrives already in that relationship. Send the platform and a photograph of the item that came off.
Two photographs settle it: the seat label, and the mounting face with the seat lifted off.
How a part is matched
Seat Spare Parts Matched by Model
A part is matched to the seat, not to the machine underneath it.
Two machines carrying the same make and model plate can leave their factory with two different seats on them, and the part follows the seat that is actually bolted down. The machine make and model is useful context and worth sending, but it is not what the part is held against.
The label
On the seat frame, close enough to read the model designation.
The damaged item
With the old one out of the machine rather than still in place.
The mounting face
Seat lifted off, which shows rails and the state of the holes.
The reply comes back in seat models
Which of our models that part fits and which it does not. If the seat on the machine is not one of ours, that answer comes too, rather than a part that turns up and does not go on.
- 24 business hours
- First reply, naming the models the part is being held against.
- 48 hours
- Fitment answer, once the photographs are in. Whole-seat replacement runs on seat fitment and compatibility.
A probe worth one email
- Send two photographs: the seat label, and the mounting face.
- Read what comes back. The reply should name our seat models.
That test tells you whether the person quoting you is matching at the seat or guessing at the machine.
Which order to place
Replacement Seat Part or Whole Seat
A component order is the right call while the structure under it is sound.
- A torn cover over foam that still recovers its shape, or an armrest whose pivot has gone loose.
- A belt whose retractor has stopped pulling in, or a presence switch gone open circuit.
- A suspension assembly sagged out of its adjustment range while the frame it sits in is still straight.
- All single-item jobs, and the seat goes back into service the day the part lands.
Structure sound — order the part
Structure spent — order the seat
Same bench, same angle. The difference is the frame, and the frame decides the order.
Holes pulled oval
Nothing new will hold square on them, whatever is bolted through.
Frame out of true
Bent by a roll or by something falling into the cab, so every other component sits against the wrong geometry.
Foam or pan gone
Foam collapsed across the whole cushion, or corrosion through the pan leaving nothing for fasteners to bite into.
You do not have to make that call alone
Photograph the frame and the mounting points while the machine is open, send them with the seat label, and back comes which of the two orders makes sense.
Where the whole seat is the order
The four ranges the parts come off are set out on their own pages.
- Forklift seats — KL01, KL11, YY03 and YY53.
- Construction machinery seats — KL02 and YS2-8.
- Agricultural machinery seats — KL03, YJ03 and YY08.
- Lawn mower seats — the YY70 deck seat.
Stocking a mixed yard
Stocking Replacement Seat Parts by Tier
A workshop running a mixed yard does not need every family on the shelf. Three tiers cover it, and your own service records decide which item sits in which tier rather than any figure we could give you.
Hold on the shelf
- Consumed by use, and they fit across more than one machine in the yard.
- They turn a machine-down morning into a fifteen-minute job, and your job cards already show them repeating.
- Seat covers · Armrests · Seat belts · Pressure sensors · Micro switches
Order per machine
- Tied to a specific seat model and a specific mounting.
- Stocking them across a mixed yard means holding variants you may never fit.
- Rail slides · Swivel rotary consoles
Order when needed
- The highest-value items in the range, and the most tightly matched.
- They belong to a machine rather than to a shelf.
- Suspension assemblies · Spindle mandrel assemblies
The judge for all three tiers is your own record of what has come off. Pull the last two seasons of job cards, count which item names repeat and on which machines, and stock against that count.
Minimums, dates and cover
Order Shapes for Seat Spare Parts
Parts are ordered on their own terms rather than on the seat minimums.
20pcs
Per stock part number
And a single piece goes out as a sample, so a workshop can confirm the fit before committing a stocking quantity.
7days
Stock parts ship in
Anything not held in stock runs with the seat line at 20 to 30 days, counted from order confirmation, because it is built on the same lines as the seats it belongs to.
12months
Warranty on parts
The same figure as the seats carry. One warranty across the range rather than a shorter one for components.
Say whether the quantity is for a shelf or for a machine that is down, because that decides which of the two routes we quote against.
- Sample first
- Worth ordering ahead of a stocking run on anything that has to mate with something already on the machine: slides, switches and assemblies.
- Model alone
- Covers and armrests are usually confirmed from the seat model without a sample piece.
- Mixed orders
- Seats and replacement seat parts run on one confirmation. Seat-level minimums and lead times are at order shapes.
What travels with a parts order
Quality Checks and Export Documents
Parts are checked under the same system as the seats they belong to.
Frames and brackets go through the same neutral salt spray at 48 hours with no red rust as the seats they come off, described in full at seat quality testing. The fourteen machines in our test centre are the ones used on finished seats, and photographs of them travel with a qualification package.
ISO 9001:2015Quality management system covering the parts line and the seat line alike.
CECarried on our seats, and on the components supplied off them.
ISO 9227, 48 hNeutral salt spray on frames and brackets, judged on no red rust.
Documents that travel with the order
- Certificate of analysis
- Certificate of conformance
- Certificate of origin
- Insurance and the rest of the export set
One email, one round
Seven Items in a Parts Enquiry
Three decide whether an item fits at all, two decide the quantity and the date, two decide the packing and what follows. In one email, the reply comes back complete.
- The part family you need
In the names used on this page: seat cover, lawn mower cover, armrest, seat belt, rail slide, suspension assembly, pressure sensor or micro switch, swivel rotary console, spindle mandrel assembly. - A photograph of the seat label
And a photograph of the damaged item with the old one still out of the machine. - A photograph of the mounting face
Seat lifted off, which shows whether rails are fitted and whether the holes are still round. - For any electrical item, the connector
Photographed on the machine loom, close enough to count the pins. - The quantity, and where it is going
Onto a shelf, or onto a machine that is down today. That decides the lead time. - The machine make and model
As context. It is useful, and it is not what the part is held against. - Marking, packing and what comes next
Whether the items need marking under your own brand, and whether this is a one-off or the start of a stocking line.
Nothing on that list needs a part number. It is a seat label, three photographs and a quantity.
