Technical rear gearbox cover for Sendero

This brass rear gear box cover is a dedicated RC-scale replacement for the Element ENDURO SENDERO TRAIL TRUCK gearbox area. Designed for hobbyist upgrades, the part provides mechanical protection and a low-mounted ballast to refine differential behaviour without altering gear geometry.

Manufactured from solid brass and weighing approximately 70 grams, the cover is precision-machined to reduce bearing clearance and improve running consistency. An integrated oil-filling port permits servicing access without dismantling the entire gearbox assembly.

Installation procedure follows standard practice: remove the existing cover, verify bearing seating, align the replacement, and torque the supplied stainless steel cap head screws evenly to prevent distortion. After assembly, confirm free differential rotation and correct bearing alignment prior to operational use.

Included items and hardware are supplied for a direct replacement: Brass Gear Box Cover 1pc and Stainless Steel Cap Head Screws 2.5x14 4pcs are provided to allow immediate fitting on compatible Sendero chassis.

Engineered as a durable upgrade for trail-oriented 1/10 Sendero rigs, this precision-machined brass cover offers stable differential behaviour and simplified maintenance access.

What tolerances should I expect when fitting bearings?

Bearings should seat with minimal axial play; the cover's machined bore aims to reduce clearance, so check for light preload and adjust shims if necessary to avoid binding.

Is the oil-fill port compatible with common filler caps?

The port is sized for routine topping and inspection; use low-viscosity gearbox oils and a compact filler tool to service without full disassembly.

Should I re-torque screws after initial break-in?

Yes. After a short run, re-check and evenly re-torque the cap head screws to account for any seating and to maintain correct bearing preload.

Does the added weight affect driveline balance?

The ~70 gram brass mass lowers the centre of gravity and can stabilise differential response; verify handling on your setup and adjust other mass distribution if required.
