Kubota M5700 Workshop Manual

If you are wrenching on a Kubota M5700 Workshop Manual tractor with the hydraulic shuttle, you have two choices: guess and hope the seals hold, or open this supplement and get the factory procedure. Over 28 years I have seen too many guys tear into a transmission only to find out later they missed a shim because they used a generic manual. This is not that. This 78-page supplement, published January 2002 by Kubota themselves, is meant to be used alongside the base M4900 and M5700 workshop manual. You get the exact changes made for the hydraulic shuttle – mechanism, servicing, and specs that aftermarket houses get wrong.

Safety Instructions: Not Optional

The manual opens with safety instructions on page H1. If you skip that page you deserve the busted knuckles and hydraulic fluid in your eyes. Kubota spells out the specific hazards for this model – high-pressure lines, rotating shafts, battery acid. I do not care if you have done a hundred tractor jobs. Read it. Then go to the SPECIFICATIONS section on H8 for the numbers that matter: engine displacement, hydraulic pump flow, tire pressures. Those are the baseline for every adjustment you will make.

Transmission Servicing – Where Most People Screw Up

Section 3 covers the TRANSMISSION. Part [1] MECHANISM explains how the hydraulic shuttle clutch packs engage and disengage. Do not skip it – understanding the flow path saves you from pulling the unit twice. Part [2] SERVICING gives you the disassembly sequence, inspection limits, and the factory torque specs for the clutch housing bolts. The manual tells you to use special tool [DATA NEEDED] for the piston retainer – you can fabricate it if you know the dimensions. But the tolerances inside that transmission are tighter than a politician’s budget. Use the numbers in this section. I have seen one guy crack a case because he reused a bolt that was stretched. The spec was 58 ft-lbs, not “tighten till it stops.”

Clutch Overhaul: Factory Steps and Required Tools

Section 2, CLUTCH SERVICING, is six pages of pure procedure. It covers removal of the clutch cover, disc inspection, and release bearing check. The manual lists the required special tool (part number [DATA NEEDED]) for aligning the disc. Do not try to use a screwdriver – you will bend the diaphragm spring. Torque for the pressure plate bolts is [DATA NEEDED] from the manual – probably around 22-27 ft-lbs but I am not guessing. Get the real number off page H2-S1. The supplement also includes the adjustment spec for the clutch pedal free play. That number changes with the hydraulic shuttle, so do not use the base tractor spec.

Hydraulic System – Mechanism and Servicing

Section 8 covers the HYDRAULIC SYSTEM. The hydraulic shuttle lives and dies by this system. [1] MECHANISM walks you through the valve spools, relief valve settings, and the shuttle shift control. Understanding that schematic is step one. [2] SERVICING gives you the procedure to replace O-rings, adjust the relief valve pressure, and bleed the system. The manual warns you to relieve system pressure before disconnecting lines – that warning is there because somebody got a face full of oil. The torque for the hydraulic hose fittings is also listed – do not guess. Cross-threading a banjo bolt on a 3000 psi system will ruin your week.

Source Validity: OEM Print vs Aftermarket Copies

I have seen reprints that blurred the torque values and wiring diagrams that showed the wrong wire colors. This PDF is scanned from the original Kubota publication. You get factory illustrations, the exact font from the 2002 print, and the supplement note that says “Use this workshop manual together with workshop manual for M4900 and M5700.” That note alone tells you this is not a generic compilation. If you need the base manual, pick up KUBOTA M4900 M5700 2000 Workshop Manual or Kubota M4900 M5700 Tractor Workshop Manual. For wheel loader guys, Kubota R420B R520B Workshop Manual – Factory Specs for Wheel Loaders uses similar hydraulic logic.

FAQ

Is this the complete workshop manual for the M5700?

No. This is a 78-page supplement that covers only the hydraulic shuttle changes. You need the base M4900/M5700 manual for the engine, steering, and electrical systems.

What about the transmission drawings – are they readable?

The scan quality is good enough to read part numbers and shim thicknesses. Some of the exploded views have small callouts, but you can zoom in. I have used it to rebuild two of these shuttles and did not have to call Kubota for clarification. The servicing sections list clearances in mm and torque in Nm and ft-lbs. Just make sure your printer can handle the fine lines – print it at 100% scale, not “fit to page”. If you need background on how a manual transmission works in general, check Wikipedia’s Manual Transmission article, but for the specific Kubota shuttle, stick with this manual. Also see Manual Transmission for basic theory if you are new to tractor powertrains.

You have a tractor that needs a clutch or a shuttle rebuild. The aftermarket manuals will tell you the general idea, but they will not give you the 2002 factory update that corrected a common leak path on the shuttle housing. This supplement has that. It is 78 pages of exactly what you need, no extra junk. Access the Factory Manual and get the right specs on your bench before you pull any bolts.
