Kubota BX1870, BX2370, BX2670 2013 Workshop Manual

Look, I’ve seen too many guys pull a head off a BX series Kubota only to find the wrong gasket in the box because they followed a generic online guide. If you’re wrenching on a Kubota BX1870, BX2370, BX2670 2013 Workshop Manual is what sits on my bench. It’s the same binder dealer techs use, covering the tractor, mid-mount mowers (RCK48-18BX, RCK54-23BX, RCK60B-23BX, RCK48P-18BX, RCK54P-23BX), and front loaders LA203A and LA243A. No guesswork.

Three Models, One Factory Manual

This manual handles the BX1870 (D722-E4), BX2370 (D902-E4), and BX2670 (D1005-E4) diesel engines. It also dives into the mower decks and loaders. The spec tables for each model start on page I-14. That’s where you find displacement, compression, and fluid capacities – all in the units you work with daily. No metric-to-imperial conversion drama.

Does This Manual Cover the Fuel System and More?

It does. The engine section includes fuel system troubleshooting, injector removal specs, and injection pump timing. Under “FONCTIONNEMENT” you get lubrication, cooling, and fuel system theory. Under “ENTRETIEN” you get the actual overhaul steps – cylinder head torque sequence, valve adjustment, and the special tools you need. For example, to R&R the D1005 head you need tool #5 (valve spring compressor) from the special tools list.

Torque Specs: Why You Need the OEM Values

Aftermarket manuals love to consolidate torque values into one generic chart. This one gives you separate tables for metric bolts, UNC/UNF fasteners, plugs, hydraulic fittings, and studs. The general bolt torque section for the tractor and mower is separated from the loader. If you reuse a hydraulic fitting based on a generic chart, you risk leaks or a snapped fitting. Kubota’s chart specs the exact thread and grade.

Check the Electrical Precautions Before You Touch Any Wiring

Skip this and you’ll fry a controller. The manual has a whole section on handling electrical components – battery disconnect order, fuse ratings, connector inspection, multimeter use, and wire color codes. The wiring diagrams are factory-correct, not redrawn by some third party. Trust me, chasing a short without this is a waste of billable hours.

7 Maintenance Intervals for the BX Tractors

The manual breaks maintenance into daily, 50-hour, 100-hour, 200-hour, 400-hour, 500-hour, 800-hour, 1500-hour, 3000-hour, annual, and biennial checks. For the mower decks, it lists 150-hour and 2-year intervals. The loader has 10-hour and daily checks. Each interval specifies exactly what to lube, adjust, or replace. That’s not a suggestion – it’s the schedule that keeps these tractors running past 5000 hours.

Source Validity: What Makes This OEM Print Different

This is a 2013 KiSC-issued Workshop Manual in its original French edition. It’s not a scanned reprint. The page numbers, diagrams, and torque tables are exactly as Kubota released. If you’ve ever seen an aftermarket copy where the torque value for a M8 bolt is listed as 27 N·m instead of the factory 25 N·m, you know why OE matters. For operators manuals, check the Kubota BX1870 BX2370 BX2670 2012 Operators Manual – Factory Specs. For larger wheel loaders, see Kubota R420B R520B Workshop Manual – Factory Specs for Wheel Loaders. The Kubota Z402-EB 2000 Workshop Manual – Factory Service Specs covers a different series but shares diesel fundamentals.
