Ursus C-355 Repair Manual

If you are wrenching on a Ursus C-355 Repair Manual and you obtained some aftermarket PDF from a forum, you are wasting time. I have seen more stripped bolts from wrong torque specs than I care to count. This manual is the factory supplement from Zakłady Mechaniczne Ursus in Poland. It is 25 pages of exactly what changed from the C-350 to the C-355. You need this on the bench, not some generic translation.

Engine Specs and Lubrication System

Page 5 lays out the specification data for the S-4002 diesel engine – bore 95 mm, stroke 110 mm, compression ratio 17:1, 50 HP at 2000 RPM. That is the baseline you need before you pull the head. The lubrication system section (chapter 2) walks you through oil filter disassembly and oil pump service. Do not skip the step about oil filter functioning on page 9 if you want to avoid a dry start. Use the URSUS C-355 Operator’s Manual alongside this for fluid capacities.

Gearbox and Transmission: What Changed

Chapter 5 covers the gearbox. The C-355 introduced a P.T.O. shaft change that affects the [Manual Transmission][LINK_ID_EXT_0] disassembly sequence. The factory supplement notes that the stripping operations remain the same as the C-350 except for the oil filter, P.T.O., foot brake, front suspension, and steering gear. If you are rebuilding the gearbox, confirm your part numbers against the specification data on page 5.

Brakes and Front Axle Adjustments

Chapter 6 gives brake setting instructions – page 15 starts the section, and page 16 has the adjustment specs. Do not guess; toe-in alignment for the front wheels is on page 18. Stub axle dismantling steps are in chapter 7. On page 17 you will find exploded views that save you time pushing out the wrong pin. Pair this with the INTERACT 4.0/6.0 Engine Repair Manual Mechanical Repairs if you are swapping power units.

Steering System: Factory Reassembly Steps

Steering gear stripping and refitting is detailed from page 19 to 22. The procedure for dismantling the steering gear off the bracket is not something you want to reverse-engineer. The manual specifies the order of shims and preload settings on page 23. Without this supplement, you risk binding the worm gear. Access the IKA-RENAULT TORINO GS-TS M.R. 61 Repair Manual if you also work on passenger cars, but for the C-355 stick to the factory source.

Why This Supplement Beats Generic PDFs

Aftermarket manuals often copy the C-350 data and skip the C-355 updates. This 25-page document comes directly from Ursus. It contains the implement linkage system chapter (9) and correct hydraulic lift specifications. I have seen a shop lose a whole day because they used a third-party wiring diagram that missed the brake control changes. Do not be that shop. If you need to understand what a [Manual Transmission][LINK_ID_EXT_1] needs for the C-355, look at page 14 – it lists the gearbox section title and references the base manual.

7 Systems Documented in 25 Pages

From the air compressor (section 1.2) to the supercarriage steering (section 1.7), every subsystem is covered. The fuel supply system (chapter 4) is short but critical – it tells you where the injection pump differs from the C-350. Weights, loads, and optional extras are on page 8. This is not a full disassembly guide; it is the supplement you must have in your hand when working on a C-355.

FAQ

Is this manual different from the C-350 manual?

Yes, it is a supplement covering changes in the oil filter, P.T.O. shaft, foot brake, front suspension, and steering gear.

What torque specs are listed in this manual?

Specific torque values are not printed in this supplement. The specification data on page 5 gives engine dimensions and capacities, but for fastener torques you must refer to the base URSUS C-350 repair manual. This supplement points out which assemblies changed so you know which sections of the base manual to re-check. Use it together with the C-350 manual to get the full picture.
