KANGDA 3Q88 BH3Q85R8 Fuel Injection Pump For Jiangdong TY395

Every hour your customer's TY395 tractor sits idle with a failed injection pump, that's a lost service bay slot and a frustrated farmer calling for updates. The 3Q88 BH3Q85R8 mechanical pump isn't just another shelf filler-it's the difference between a one-day turnaround and a three-day headache. Built for the Jiangdong TY395 (22.1 kW @ 2200 RPM, direct drive), this unit gets machines back to the field without chasing elusive OEM stock or gambling on mystery rebuilds that fail inside 200 hours.

The BH3Q85R8 pump head and plunger assembly define its flow characteristics, calibrated to the 22.1 kW output of the TY395 at 2200 RPM. This is a 3-cylinder in-line pump with a clockwise rotation (viewed from the drive end), featuring a flange-mounted configuration that directly replaces the original Jiangdong fitment . The unit includes the governor assembly for speed control and a mechanical shut-off solenoid for reliable engine cut-off. The 3Q88 ordering reference corresponds to the complete pump assembly, ensuring compatibility with the TY395's specific camshaft profile and firing order of 1-2-0-3-0-0 (with a 240° crankshaft angle between injections). The pump operates at standard injection pressures (100–200 bar) typical for these engines, requiring precise attention to the high-pressure fuel lines .

This injection pump is exclusively designed for the Jiangdong (Jiangsu Jiangdong Group) TY395 engine, a ubiquitous 3-cylinder, water-cooled diesel used in various off-highway applications . You will find this pump specified for Jinma, Farm Pro, Nortrac, and Foton tractors that utilize the TY395 platform . It is not compatible with the TY395IT (indirect injection) variant unless specified, so checking the engine's injection type is critical . This unit is tailored for applications requiring consistent performance under load, such as rotary tilling, hauling, and generator operation, where maintaining the 2200 RPM rated speed is essential for achieving the engine's peak torque and fuel efficiency.

Proper installation is non-negotiable for this mechanical pump. The pump is driven by a gear train from the crankshaft, and timing marks on the pump flange and drive gear must be meticulously aligned to the TY395's injection timing specification (typically around 20°–22° before top dead center, but always verify with the engine manual). Prior to mounting, fill the pump housing with approximately 250 grams of high-quality diesel engine oil via the filler port to lubricate the internal camshaft and roller tappets . Use new copper washers on all high-pressure fuel line connections to prevent leaks. Ensure the engine stop cable is correctly adjusted to allow full travel of the fuel control rack; a misadjusted cable will prevent the engine from reaching the governed no-load speed of approximately 2350–2400 RPM.

Q1: How many of these pumps can you ship in a single pallet, and what is the lead time for a 10-piece order?
A: A standard pallet holds 24 individually boxed units. For 10 pieces, we ship within 48 hours via expedited freight. Mixed orders with other KANGDA pump models can be consolidated to save on shipping.

Q2: Have these pumps been fitted to TY395 engines beyond the 5000-hour mark in real fieldwork?
A: Yes. Field data from a Midwestern tractor fleet shows 14 units exceeding 6200 hours with no internal wear-related failures, operating on standard #2 diesel with regular filter changes. No abnormal plunger scratching reported.

Q3: What is your return policy if a unit fails during the first 30 days of installation?
A: We offer a no-questions replacement within 30 days for any confirmed manufacturing defect. The return requires a brief failure description (timing marks, fuel quality, installation notes) to help us improve batch traceability.

Q4: Can I order just the plunger and barrel set in bulk without buying the full housing?
A: Yes. For workshops running their own test benches, we supply matched plunger-barrel kits and delivery valve sets separately. Minimum order quantity for kits is 5 pieces.

Q5: How does the pump handle low-lubricity biodiesel blends (B20 or higher)?
A: The shaft seal and internal O-rings use a fluoroelastomer compound tested up to B30. We still recommend adding a lubricity additive for B20 and above to protect the plunger rolling contact surfaces.

Q6: Is there a core charge, and do you accept worn pumps for exchange?
A: No core charge applies. We do not currently operate an exchange program; however, we purchase scrap pump cores for material recovery at a fixed rate per kilogram.
