How hard is disassembling and assembling an marauder engine?

you can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered

Wiring, schematic, electrical diagrams, error/fault codes, torque specs, parts info, assembling-disassembly procedures, engine problems etc are basic contents of these online books they here on this website https://big-manuals.com/

within seconds u can get the access and it's totally illustrative complete

best advice is to get the caterpillar or stamford dealer service center involved as the advice will be specialized

That requires pretty much a complete disassembly of the engine in order to get to the rod bearings. Best left to a professional.

If it is not broken, don't fix it. Your gears look fine just as they are. Rebuilding a gear box means replacing all gaskets, bearings and seals. Plus doing any crankshaft connecting rod repairs and shift fork replacements. Removing the gears from the shafts is not necessary unless a gear tooth or slider gear engaging stem is broken. Some of the gears are part of the shaft and can not be removed.

Broken starter ropes or failure to retract are both repairs that are fairly easy. However, the spring can be nasty as it is under tension (or should be when reassembled). This can be risky if you are not familiar with the internal construction as you disassemble the unit.

The cause of a broken cord is obvious. The cause for a failure to retract could be a broken spring, tangled or frayed rope, or some other mechanical failure. A broken spring will require total disassembly of the starter mechanism - fortunately there really isn't that much involved.

With some designs, it is possible to replace the cord without fully disassembling the starter mechanism - by threading the cord in and tying a not in the end - but after rotating it several turns to put the proper tension on the spring. This is relatively safe but may be frustrating as 3 hands are sometimes needed.

Where safe disassembly is not obvious, I would recommend that you refer to a book on lawn mower or small engine repair from the library or the service manual for the mower, if possible. You may be able to find specific step-by-step instructions which will minimize your risk of injury from an encounter with an uncontrolled spring.

When the rope pulls out and retracts normally - but doesn't do anything else - the most likely cause is a problem with the one-way clutch. This may be part of the spring-rope assembly - usually removable as a unit - or attached to the flywheel. The most common problems are gummed up lubrication or a broken spring or other damaged or worn parts.

anyway... there is a torx screw in the middle of the clutch drum(metal part that rotates).you will need to use a piston stop,to stop the engine turning while trying to undo the torx screw. i am assumig the starter is in front of the engine not at the back. once the screw is undone the clutch will come off and so will the starter cover.(source: neil)

Thanks for using Fixya

Have a nice day!

sometimes the brush assembly melts because of the way it was designed, could be broke, but u have to take it out and look at the assembly first, turbine is powered through air suction
