Unlike generic adjustment plates, the 1878000635 features a 400mm diameter precision-machined to match Euro truck specifications. This exact fit eliminates guesswork during adjustment, ensuring the clutch gap is set to OEM standards of 2-3mm and preventing premature wear on clutch components. Each plate undergoes dimensional testing to confirm compliance with stated tolerances.
Over time, clutch plates wear down, increasing the gap between the plate and flywheel. This adjustment plate allows technicians to correct the gap without disassembling the entire clutch system. For fleet operations, this reduces maintenance time by up to 50%, minimizing vehicle downtime and getting vehicles back into service faster.
Constructed from heat-treated carbon steel, the plate resists bending and deformation during use with standard maintenance tools. It can withstand repeated use for up to 100+ adjustments without losing dimensional precision, making it a cost-effective addition to repair shop and fleet depot tool inventories.
This adjustment plate is intended for maintenance on Higer buses (both urban and intercity models) and Euro trucks including tractor trailers and delivery vehicles. It is particularly critical for vehicles with high mileage of 100,000+ km where clutch wear is common, as well as trucks used in long-haul transport where misaligned clutches can lead to reduced fuel efficiency and potential transmission damage.
Place the 1878000635 plate between the clutch plate and flywheel
Use a standard torque wrench and socket set to adjust the pressure plate bolts
The plate's flat surface ensures even pressure distribution, setting the correct clutch gap
Remove the plate after adjustment
Test the clutch pedal to confirm a firm, consistent response
Yes, the 1878000635 plate is designed for Volvo FH12, FH16, FM12 and FH series trucks. For other truck models, please provide your vehicle model number and we will confirm compatibility.
Only a standard torque wrench and socket set are needed. A step-by-step user guide is included with each plate purchase.
For Euro trucks used in long-haul transport, clutch adjustment is recommended every 80,000 km. For Higer buses operating in frequent stop-start conditions, adjustment is recommended every 50,000 km to maintain optimal performance.
