Renault Trucks Renault 5, Extra, Renault 9, Renault 11, Renault 19 1997 Workshop Manual

If you’ve ever chased a gearbox issue on a Renault 5, Extra, 9, 11, or 19 and found aftermarket instructions that skip critical tightening torques or leave out the reverse gear brake details, you already know the pain. This is the factory Renault Trucks Renault 5, Extra, Renault 9, Renault 11, Renault 19 1997 Workshop Manual — 111 pages of OEM data, not a reprint or a third-party rewrite. It’s the document that Renault itself issued in February 1997 (part number 77 11 192 787), superseding earlier JB gearbox manuals and technical notes. On my bench, I’ve used this exact manual to confirm torque values for the JB0, JB1, JB2, JB3, JB4, JB5, and JC5 gearboxes. It’s the only source I trust when the customer has a 1997 Renault 19 with a grinding third gear.

Manual Gearbox: What the Factory Covered in 21 Sections

The TOC starts with a section view and identification plate decoding — something aftermarket PDFs always get wrong. Page 21-2 shows you exactly how to read the gearbox type, suffix, and production number, including the new letter prefix system for numbers over 999,999. Following that, the cross-section and tightening torques table gives you the numbers in daN.m. Convert to ft-lb (1 daN.m ≈ 7.38 ft-lb) if you prefer imperial, but the spec is the spec. The manual then steps through gears, ratios, capacity and lubricants, special points, modifications, consumables, and parts that must always be changed. Then it dives into gearbox repair — shafts, differential, internal controls, lubrication channel, reverse gear shaft, reverse gear brake, speedometer, thrust pad guide tube, and assembling the housings. Each exploded view at the end has a parts directory, so you can order the right snap ring or synchro without guessing.

Torque Specs and Fluid Capacities (daN.m Converted)

Cross-section and tightening torques in daN.m are listed right after identification. For example, the JB4 4-speed housing bolts get 2.5 daN.m (about 18.4 ft-lb). The manual also covers the JC5 gearbox — a common upgrade in the Renault 19. Capacity and lubricant specs are on page 21-28. Use the specified oil grade; the manual calls out the exact viscosity and quantity. Miss that, and you’ll grind synchros in 10,000 miles. I’ve seen it.

Why You Need Factory Specs for the Brake and Reverse Gear

The reverse gear brake is a notorious failure point on these Renault gearboxes. This manual devotes a whole section to it (page 21-84 in the PDF). It shows the brake band clearance adjustment and the correct tightening sequence for the lock nut. Aftermarket manuals usually say “adjust until it feels right.” That’s how you snap the brake band. The factory procedure uses a specific feeler gauge measurement. The same goes for the Brake — not just the gearbox brake but the linkage and cable routing that interacts with the reverse lockout. Get the factory data, or get ready to split the case twice.

Does This Manual Cover the Fuel System or Engine?

No. This is a dedicated manual gearbox workshop manual. It covers transmission, clutch linkage, shafts, differential, internal controls, and speedometer drive. If you need engine data, fuel injection, or body electrical, you’ll want the matching vehicle-specific workshop manual. But for the gearbox — JB0 through JC5 — this is the final word.

Provenance: Why This Isn’t a Chiltons or Haynes

This is an original Renault factory workshop manual, published in February 1997 by Renault Trucks. It cancels and replaces earlier JB gearbox manual part numbers 77 11 093 922 and JC5 gearbox manual 77 11 092 186, plus technical notes 1978, 2127, 2229A, 2284A, 2383A, 2457A. The copyright notice states copying or translating without written authority is forbidden — that’s how you know it’s genuine OEM. Aftermarket manuals reprint anecdotal torque specs that are off by 10%. I’ve compared. This manual has the exact Nm values from the factory assembly line.

For a deeper understanding of manual transmission operation, the Manual Transmission article on Wikipedia explains the basics, but it won’t tell you which shaft needs a puller and which bearing is preload-sensitive. For that, you need this manual. Another good resource is Manual Transmission repair guides on YouTube, but they can’t replace the exploded view parts directory on page 21-107 that lists every washer and snap ring by dimension.

FAQ

What gearboxes are covered in this manual?

JB0, JB1, JB2, JB3, JB4, JB5, and JC5.

Does this manual include torque values for all bolts?

Yes. Cross-section tightening torques are given in daN.m for each gearbox type, covering housing bolts, yoke nuts, bearing retainers, and the reverse gear brake. The table also includes the original factory conversion from the old daN.m system. You’ll also find gear ratios, lubricant capacity, and a list of special tools needed. The exploded views at the end (pages 21-108 onward) include parts identification codes for ordering. If you’re rebuilding a JC5 for a Renault 19, this manual saves you from measuring every shim yourself — the factory cold shim selection procedure is there. Just remember to replace the differential bearing preload shims exactly as shown, or you’ll get noise on coast-down.

Bottom line: if you’re tearing into a Renault 5, Extra, 9, 11, or 19 manual gearbox from 1997, this is the document you want on your tablet or printed out. Access the Factory Manual and keep it within arm’s reach of the workbench. No more guessing on snap ring thickness or torque wrench settings.
