Part of the New Holland Repair Manuals.
Track tension goes slack on an E35B and the question is whether the adjuster is losing grease or the idler has started to walk. This manual settles it with the actual procedure and the torque figure that goes with it, which is more than a forum thread or a parts diagram gives you.
It is the 951-page New Holland service manual (publication S5PW0033E02) for the E30B from serial PW14-46519 up and the E35B from PX15-21105 up, both built around the 3TNV88-BPYB engine. The Specifications, Maintenance, System, Disassembly, Troubleshooting, Engine and options installation sections cover machine dimensions, standard working times, hydraulic circuit operation, full teardown and reassembly, and fault trees for the hydraulic, electrical and engine systems.
Every hour the machine sits is a crew standing still. The download is immediate and the PDF prints: pull the pages for the job, take them to the bench, and let them get dirty.

New Holland E30B, E35B Common Problems This Manual Covers
Travel reducer seal weeping gear oil
Oil past the travel planetary reducer seal shows as a film on the inside of the track frame long before the final drive gets noisy. The Disassembly Section walks the travel motor and reducer apart seal by seal, so you can replace the shaft seal instead of condemning the whole unit.
Manual Section: Disassembly Section p. 266Track sags and slaps at speed
A loose track usually needs the crawler adjuster serviced rather than a new rubber crawler. The Disassembly Section gives the tension procedure and calls for the crawler adjuster grease nipple to be tightened to 74 N-m (54.6 lbf-ft) before grease is fed in.
Manual Section: Disassembly Section p. 441Worn lower rollers throwing the crawler
Rollers that run dry wear the tread and flange until the crawler rides off in a tight turn. The Disassembly Section lists a standard lower roller flange O.D. of 107 mm (4.21 in), so you can measure what is on the machine and decide whether it is worth reusing.
Manual Section: Disassembly Section p. 458Weak boom lift, arm stalls under load
Slow cycles and an arm that quits in hard material point at main relief pressure or a tired pump rather than the cylinder. The Maintenance Section sets P1 and P2 main relief valve pressure at 23.0 +0.6 MPa (3340 +87 psi), which gives you a number to gauge against before anything comes apart.
Manual Section: Maintenance Section p. 90Pilot controls dead or hesitant
Levers that feel lifeless, or that hesitate until the oil warms, usually trace to the pilot control circuit rather than the main pumps. The System Section documents the solenoid valves in that circuit, including an SV-1 and SV-2 relief set pressure of 3.5MPa (507psi) and a 15L/min (3.96 gal/min) flow rate.
Manual Section: System Section p. 259Overheating after a cooling system repair
Dust packed into the core cooks a compact excavator quickly, and a partial refill after a hose job leaves air trapped in the system. The Specifications Section lists cooling water capacity at 4.0 liter maximum with 2.0 liter in the engine itself, so you know when the system is genuinely full.
Manual Section: Specifications Section p. 33Intermittent no-crank and stuck warning lamps
A machine that will not crank one morning and starts fine the next is usually a corroded ground or a chafed connector, not a failed controller. The Troubleshooting section carries separate fault trees for the electrical system, the hydraulic system and the engine, so you follow one to a test point instead of swapping parts.
Manual Section: Troubleshooting p. 522Frequently Asked Questions
Which machines and serial numbers does this manual cover?
It covers the New Holland E30B from serial PW14-46519 and higher and the E35B from PX15-21105 and higher, both compact hydraulic excavators. The New Holland publication number is S5PW0033E02.
Does it include engine repair or only the machine?
The Engine Section covers the 3TNV88-BPYB in its own right, opening with engine general specifications and principal engine specifications and running through repair of the engine itself. The Troubleshooting section adds a separate engine fault tree. p. 558
Are torque specifications included?
Yes. The Maintenance Section carries standard tightening torque tables for capscrews and nuts by thread size, strength class and lubrication state, starting at M6 coarse thread with 4.4 ± 0.5 N·m. Individual procedures in the Disassembly Section also print their own torque values at the step where you need them. p. 62
Does it cover undercarriage work such as rollers and idlers?
Yes. The Disassembly Section covers roller, idler and rubber crawler removal and installation, with a separate procedure for the optional steel track link, including tightening the lower roller capscrews to 208 N-m (153 lbf-ft) with the machine lowered into full contact with the ground. p. 453
What do I get after purchasing this New Holland E30B manual?
Straight to your device: 951 pages of searchable Service Manual, downloadable the moment payment goes through.
Can I print just the pages I need from this New Holland E30B manual?
Yes. No DRM, nothing blocks printing, so run off the pages you need on whatever printer you have.
