Dynapac LG 140, LG 160, LG 200, LG 250, LG 300 1998 Workshop Manual

You’ve got a Dynapac LG 140 that won’t vibrate, or an LG 300 with a seized eccentric shaft. Without the right specs, you’re guessing – and guessing on compaction equipment costs time and money. This Dynapac LG 140, LG 160, LG 200, LG 250, LG 300 1998 Workshop Manual gives you the OEM factory data from Svedala/Dynapac. 18 pages of what you need: fluid capacities, hydraulic diagrams, and eccentric timing procedures. No generic reprints, just the original print.

Technical Data on Page 3 – Fluids and Engine Specs

Page 3 lists engine oil, hydraulic oil, and eccentric shaft lubrication capacities for each model. The LG 140 with Honda GX160 takes 0.6 qt (0.65 L) of engine oil, while the LG 250 with Yanmar L60AE takes 1.1 qt (1.15 L). Those are factory numbers – not aftermarket estimates. You also get engine RPM, VPM, and fuel tank capacities. If you’re filling a new plate or diagnosing a leak, start here. Every model in the LG 140, LG 160, LG 200, LG 250, and LG 300 line has its own row. Don’t assume one spec fits all.

Hydraulic Diagram – Page 5 for LG 140 Through LG 300

Page 5 shows the full hydraulic diagram for these models (it also covers LG 450/500/700, but the diagram is shared). Page 6 is a separate diagram just for the LG 550. If you’re tracing a dead pump or a broken line, these diagrams use OEM symbols – not some redrawn mess. Trace flow direction, check valve placement, and understand the eccentric control system. The manual also includes a hydraulic system overview on page 7. Without this, you’re poking around blind.

Eccentric Element Assembly – Pages 9 to 15

Timing the eccentric element is the most critical repair on these plates. Page 11 gives you the timing procedure. Get it wrong – the plate vibrates out of phase, or not at all. The manual walks you through control shaft assembly (page 9), drive shaft (page 10), eccentric element (page 12), hydraulic pump (page 13), and piston assembly (pages 14-15). Eccentric housing identification is on page 8. Each step is broken down with part orientation. You need this when you’re replacing bearings or seals. The piston assembly pages include two pages (14 and 15) of detailed views – that’s where most techs mess up the snap ring placement.

Troubleshooting Page 16 – Common Failures

Page 16 covers a short list: engine won’t start, no vibration, hydraulic oil overheating, poor forward/reverse drive. It’s not a full diagnostic tree, but it points you to the right subsystem. For example, loss of vibration often traces back to the eccentric shaft timing or a failed hydraulic pump. The troubleshooting section is a quick-check before you tear into the assembly. Use it alongside the diagrams to narrow down the fault. That page alone can save you a full afternoon of hunting.

Why the Factory Manual Beats Aftermarket Copies

This is a scanned OEM workshop manual from 1998, published by Svedala Dynapac. Aftermarket manuals often skip torque values, use generic images, or omit the timing procedure. This one has original hydraulic diagrams and part numbers. Cross-reference it with the Dynapac LG 140 Parts Catalog – OEM Factory Specs for Plate Compactors for exploded views. Need a parts breakdown for the LG 160? Grab the Dynapac LG 160 Parts Catalog – OEM Factory Specs for Plate Compactor to match bolts and seals. For the LG 200, the Dynapac LG 200 Parts Catalog – OEM Spare Parts Manual complements this workshop manual. These are all OEM – not aftermarket junk. If you’re dealing with a seized gearbox, that’s a different service – consult the Manual Transmission guide. The principles of operation on page 4 explain how vibration is generated, which ties into basic Manual Transmission mechanics.

FAQ

Does this manual include torque specs for the eccentric housing bolts?

The manual does not list bolt torque values. You will need to follow standard thread-lock and torque-to-yield for M8 bolts, but the factory does not provide explicit numbers in this document. However, the technical data gives fluid capacities and engine specs. For tightening the eccentric housing, use the general guideline of 30-35 ft-lb with thread-locker, but confirm with a separate Dynapac service bulletin if available.

Can I use this manual for the LG 450 or LG 700?

No. This manual covers LG 140 through LG 300 only.

OEM specs, original diagrams, and real troubleshooting – this is what the factory issued to techs in 1998. 18 pages, no filler.
