New engine rebuild parts from Dubai: gaskets, pistons, bearings, timing kits

The fleets are commercial and long-lived, which is what makes an old engine worth restoring. Business Daily reported Isuzu at 47.8% of Kenyan new-vehicle sales in 2025, and a car-sales blog put the Hilux and Land Cruiser 70 together at 49.7% of Ugandan sales the same year. Trucks and pickups like these are kept on the road for years, and a workshop that can machine the block and head would rather renew what wears than fit a different engine.

In our own notes the best-defined trade basket for Kenya and Uganda is the engine kit for Isuzu 4HK1 and 4JJ1 trucks, listed beside clutches, brake drums and injectors. That is our reading of the trade and not a measured share. It fits the export requests we receive from East Africa, where engine internals and fuel-injection parts are among the most requested lines.

The UAE-reported figures show the scale of the flow without telling us our part of it. UN Comtrade's 2023 data, the latest the UAE has filed, record US$479.5M of diesel engine parts and US$219.0M of petrol engine parts leaving the UAE, re-exports included. Comtrade does not separate new from second-hand, so treat these as the size of the market and nothing more.

A rebuild order is rarely one part. The head gasket and the bearings go in together because the engine is already open, and the timing set and water pump are renewed for the same reason. Quoted as one list, every line is checked against the same engine code, so the pieces fit each other as well as the engine.

We quote new injectors and new injector parts, new pumps and new bearings. We do not quote rebuilt or remanufactured injectors, pumps, turbochargers or short blocks, and we do not supply complete engines or half-cuts. Those are outside what we export, and a line that cannot be quoted new is left off the list.

Genuine is the carmaker's own part in the carmaker's box. OE-brand is a part from a maker that also supplies the carmaker, sold under its own name. Denso and Aisin are examples: Wikipedia describes both as Toyota Group companies, and says Denso drew 44% of its revenue from other carmakers in the year to March 2016. Quality aftermarket covers other reputable makes. We name the brand and the grade on every line.

Taiho shows how the middle grade works for engines. Its own history page says orders from Toyota led it to begin making engine slide bearings in 1961. Riken piston rings, now part of NPR-RIKEN, are catalogued by engine model, displacement, cylinders and OEM reference. A brand name never settles the grade by itself, so we check each maker's relationship to the carmaker before a line is called OE-brand.

The one engine part in our November price check is the water pump for the 1GR-FE V6, Toyota number 16100-39456. A Dubai parts site listed the Toyota pump at AED 397, NPW at AED 214 and GMB at AED 229 on 3 November 2026, all with 5% VAT included. The aftermarket pumps cost 0.54 and 0.58 of the Toyota price. That is one part on one day and a counter price, not a quote, but it shows the size of the gap.

Bearings, rings and gaskets close up inside the engine, so a wrong or fake part is found only after the work is done. That is a reason to pay for a named brand where the saving is small, and a reason to take quality aftermarket where it is large. A mixed order is normal: OE-brand bearings beside an aftermarket gasket set, each line carrying its own grade.

Taiho says so in its own words. Its aftermarket page has a section on fighting fake manufacture, which records that thousands of imitation bearings carrying Taiho's licensed trademark were seized after an investigation at a factory in China on 20 July 2004. The page warns that fake bearings damage the engine and tells buyers not to buy, sell or use them. It also announces a new label from 2020, so a photo of the label is worth asking for.

The UAE has its own record. A trade report dated 16 December 2024 says Al-Futtaim Automotive's raids that year took more than 2.5 million fake components worth nearly AED 7.46 million, of which AED 2.81 million were oil filters. The report does not itemise engine parts, so it shows the scale of the trade and not the share of bearings or rings.

Our protection is the grade written on each line and your own check before you pay. Ask for a photo of the box label and of any number printed or stamped on each ring set, bearing shell or gasket set, and compare it with the number on the quote. A part that arrives without the number you were quoted is a reason to stop and ask, not to fit it.

Start with the engine code and the number stamped on the engine, then the chassis number or VIN of the vehicle. The code names the family and the stamped number points to the exact build. A code alone is not enough: Toyota's June 2015 release gives the 1GD-FTV as 2,754 cc and the 2GD-FTV as 2,393 cc, and says specifications vary according to market.

Then send the sizes your machine shop cut. Piston and ring sets are sold in steps over the standard bore. Metric listings step by 0.25, 0.50, 0.75 and 1.00 mm, and some brands list inch sizes of .020, .030 and .040. A standard bore of 80.00 mm cut to 80.50 mm, for example, takes the set listed at +0.50 mm. Name the unit you are measuring in, because the same number means a different part in each.

Bearings follow the crankshaft and not the bore. After the journals are ground, the set is chosen by the new journal size, and retail listings of Taiho bearings carry the size in the product name, with STD meaning standard. Send the journal sizes your shop recorded, the number of cylinders, and a photo of any old shell showing its markings. Add the country you are buying for and the grade you want on each line.

Each family below has its own page covering the parts a rebuild needs and the vehicles that carry it. Use them for the code detail; this page covers what is common to every rebuild. An engine's internals do not change with the steering side of the vehicle, so the engine code does the matching, not the market the vehicle drives in.

Our notes flag Toyota 1GD, 2GD, 1KD, 2KD, 2TR, 1GR, 1VD and 1HZ, Nissan YD25 and QR25, Isuzu 4JJ1 and Mitsubishi 4D56 and 4N15 as families shared between Gulf-market and right-hand-drive versions. The engine-code mapping behind that list was not confirmed from a maker catalogue, so every quote is checked against the chassis number or VIN before it goes out.

Rules for second-hand parts are the reason many buyers order new. Mauritius's import regulations prohibit second-hand injector nozzles, oil seals, bearings and engine mountings, among 18 groups. Zimbabwe's CBCA programme is written for used vehicles and used spare parts, with a fee of 0.5% of value, a $245 minimum and a 12% CIF penalty without the certificate. Tanzania's TBS notice sets a pre-shipment inspection for used parts from the UAE. A new consignment sits outside all three, and your clearing agent confirms what applies.

Sanctions law touches engines too. The US list for Russia and Belarus names all of HS 8407, 8408 and 8409 and every 8482 bearing heading, and the UK's high-priority list names ball and roller bearings. We do not supply Russia, Belarus or any other refused destination, and we do not quote engine parts for onward shipment to them. A person asks where the engine runs before a list is quoted.
