Clark-hurth CMP 50, CMP 60, CMP 70, CMP 75S 2000 Service Manual – 604 Pages of Factory Specs

Nothing steams me more than a kid with a laptop under a forklift, flipping through some bootleg PDF with wrong torque values and missing steps. I’ve been turning wrenches since before most of you were born, and I can tell you right now – the difference between a machine that runs for another 10,000 hours and one that grenades in a month is whether you’re working off OEM specs or some third-party rewrite. This Clark-hurth CMP 50, CMP 60, CMP 70, CMP 75S 2000 Service Manual is the real deal. 604 pages, factory-printed, straight from the guys who built the damn thing. If you’re chasing a hydraulic leak, rebuilding a 4.3L V6 LPG engine, or trying to figure out why the transmission won’t shift, this is the document you put on the bench. Not “similar to” – exactly what the dealer techs used.

You’ll get the maintenance schedules, the safety procedures, the disassembly sequences, and – most importantly – the exact torque specs that keep bolts from stripping and gaskets from blowing. Don’t trust aftermarket manuals. I’ve seen them list 80 ft-lbs on a cylinder head that needs 105. That’s how heads warp and oil leaks start. This manual came from Clark Material Handling GmbH in 2000, revision 3. It’s trilingual – French, English, Spanish – so you get the terminology in three languages. That alone tells you it’s international factory grade.

Safety Maintenance: Lift Points, Jacking, and Towing

The first group in this manual – Entretien de Sécurité – covers lifting, jacking, blocking, and towing procedures. If you’ve ever seen a forklift come off jack stands because someone used the wrong lift point, you know why this matters. The manual specifies how to safely block the mast and frame before you go underneath. That’s not just liability CYA – that’s how you keep your head attached to your shoulders. I don’t care if you’re a weekend DIYer or a shop foreman: read that section first.

1004-42 Diesel Engine: Complete Overhaul Specifications

Under MOTEUR 1004-42 DIESEL, you’ll find the full repair manual for the 4-cylinder diesel. It starts with general specs, then walks you through cylinder head assembly, piston and connecting rod sets, crankshaft and bearing clearances, timing drive, cylinder block, and lubrication system. The section on Calage du moteur (engine timing) gives you the exact procedure to set injection timing. And the Liste d’outils spéciaux tells you exactly which pullers and adapters you need. No guessing.

4.3L V6 Gas/LPG Engine: Rebuild and Troubleshooting

Got a CMP 70 or 75S with the 4.3L V6 running on LPG or gasoline? This manual covers MOTEUR A ESSENCE/GPL 4.3, V6 with converter stall test, oil and filter specs, and a full engine revision section. That includes disassembly, cleaning, inspection, and reassembly. I’ve rebuilt these engines – the torque sequence on the intake manifold is critical, and aftermarket manuals often swap it. This document gives you the Clark-hurth factory sequence.

Transmission Overhaul: Specs and Revision

The transmission section (TRANSMISSION) is straightforward: specifications, description, and the full revision procedure. If you’re tearing into a powershift or a manual gearbox – and you need background on what a Manual Transmission actually does – that external article helps. But for the Clark-hurth unit, you need the page that shows clutch pack clearances and shift valve adjustments. That’s in here. For additional depth, the Spicer Clark-Hurth HR Transmission Service Manual covers the heavy-duty cousin of these units.

Later in the manual, the hydraulic circuit (CIRCUIT HYDRAULIQUE) gives you pump revision, control valve disassembly, and priority valve overhaul. That’s where most mast drift issues get fixed. Don’t R&R a lift cylinder until you’ve checked the seal kit part numbers from the spec sheet.

Why This Factory Manual Beats Aftermarket Copies

Every aftermarket “reprint” I’ve seen omits the electrical schematics or runs them through a scanner that blurs wire colors. This Clark-hurth original has the full CIRCUIT ÉLECTRIQUE with board-level diagrams for the dashboard. It also includes the mast section (MATS) with chain maintenance, cylinder revisions, and mast control adjustments. The 604 pages are complete. If you need the companion for older Clark models, check the Clark-hurth 55A SERIES II Service Manual – 136 Pages of Factory Specs or the Clark-hurth SM-715, TMX12-25, EPX16-20s 2007 Service Manual – 502 Page OEM Facto.

For a quick primer on transmission basics, read the Manual Transmission entry on Wikipedia – it’ll give you the general theory, but don’t use it for the Clark-hurth rebuild steps. Only the OEM manual has the right end-play measurements.

FAQ

Does this manual include wiring diagrams for the electrical system?

Yes. The CIRCUIT ÉLECTRIQUE section has full circuit schematics and dashboard diagrams.

What engines are covered in the 604 pages?

Two engines: the 1004-42 diesel (4-cylinder) and the 4.3L V6 gas/LPG. Each engine chapter includes complete disassembly, inspection, torque specs, and reassembly. The V6 section alone runs over 100 pages with converter stall test, oil filter specs, and a full engine revision including cleaning and inspection of pistons, rings, bearings, and cylinder heads. If you’re rebuilding either engine, you have every bolt torque and clearance measurement you need directly from Clark-hurth’s factory engineers. No guesswork, no cross-referencing a Chilton’s book that lumps three different engines together.

Don’t waste billable hours chasing bad data. I’ve been down that road – blew a hydraulic pump because an aftermarket PDF said the relief valve setting was 200 psi higher than it should be. That cost me a week and a customer. This manual is your insurance policy.
