About Us

We keep diesel and heavy engines running — the right rebuild part, sourced fast and shipped worldwide.

High Quality Motor Service is a specialist supplier of diesel and heavy engine rebuild parts. We exist for one reason: to get the exact part you need into your hands quickly, so machinery gets back to work and downtime stops costing you money. From a single gasket to a complete overhaul kit, every order is backed by real engine expertise.

Who We Are

Diesel and heavy engines are the backbone of agriculture, construction, power generation, and industry. When one goes down, the cost is measured in hours. We built our catalogue around the way engines are actually rebuilt — organised by brand → engine family → model → part type — so you can find the right component with confidence instead of guesswork.

We supply both genuine OEM and high-quality aftermarket parts across every major engine family, including Deutz, Perkins, Kubota, Yanmar, Caterpillar, and Lister-Petter. Every listing cross-references its part numbers and fitment, and everything we sell is covered by our warranty.
