Klaus repairs about anything in, on, and around an LGB loco or car that can be repaired. In case it is beyond repair, the damaged part will be replaced with either an Original LGB part or be re-made/manufactured by Klaus in his workshop. 

The most common repairs are replacing motors , repair short circuits and/or faulty wiring, replacing worn-out and/or missing parts, replacing all kinds of decoders. Sophisticated "repairs" include tracing faults and error diagnostics e.g. in motor malfunctions, tricky short circuits, worn-out decoders/boards. The diagnostics-resulting installations (e.g. driving decoder and/or sound installations) with  model-fitting and model-enhancing loudspeaker cutouts, custom-built adapters, custom cables and wiring and more.

Work Scope
Klaus repairs LGB locomotives and cars in complete compliance with the old German LGB standards. These standards were co-developed by Klaus while he consulted LGB Lehmann Patentwerk in product improvement. Klaus also worked in close co-operation with Günter Ruhland, the General Mold Master LGB.

Repairs by Klaus guarantee the continuation and sometimes the reinstatement of Original Old German LGB standards in your LGB locomotive and LGB car.

All spare parts used in repairs are either Original LGB spare parts or - if those Original parts are no longer available on the market - are re-engineered by Klaus according to old LGB standards.

Klaus uses Bühler motors in repairs which are the Original motors used by LGB in Germany. Replacement decoders are tested by Klaus and made by German manufacturers that are or have been suppliers for Märklin LGB in Germany..

Klaus utilizes specialty glue, ONLY.

All cables and wires used in repairs are complying to standard LGB wire gauge.

Solutions for operating 24/7

If your loco(s) literally run 24/7 or 18/7 or 12/5 like true workhorse locomotives in toy shops, botanical gardens, children's hospitals, real estate offices, restaurants, museums just to name a few- you need a special solution. Whenever the engines are operated for at least 8-10 consecutive hours every day you need a special solution.  Just imagine the wear and tear on those locos! Why a special solution?

Where the problem starts:The plastic housing of the locomotive makes/is the bearings for the axles. The plastic contains glass particles to enforce the strength and stiffness of the housing. During the operation the axles work themselves into the plastic resulting in a widening of the plastic bearing. In the end the locomotive axles start wobbling in the way too large (axle) opening of the housing. The plastic gear wheel on the axle of the locomotive will not be defined in its position anymore resulting in excessive wear on the plastic gear wheel.

"Quick fixes" - that don't help much:Once problems arise with the plastic gear wheel one might tend to exchange the plastic gear wheel. However, this would be a short lived fix as the gear wheel will wear out pretty fast, again. The regular problem fix would be an exchange of the motor block housing. In case of a daily, continuous operation the engine will end up with a worn out motor block housing soon, again.

The professional Solution: This calls for the  installation of a different kind of bearing, e.g. ball bearings, roller bearings or sintered bronze bearings, to enforce the motor block housing to a degree withstanding the continuous impacts. However this kind of installation requires a massive re-work of the axle/ motor block design including these activities: remove the loco wheels from the axle, put the new bearings in position on the axle and re-install the loco wheels with the correct quartering in case of a steam loco. The  position of the former bearing in the motor block needs to be widened to accommodate the new bearing. This work step requires exact industrial precision since the position of the bearing is crucial for the smooth operation of the gear work in the motor block .(Please do not try this at home- not even if your wife is not home ) .

Precision manufactured bronze bearing


 Klaus' Professional Solution: 
Your Famous Klaus took a different approach by developing and manufacturing a specific sintered bronze bearing. This bronze bearing is C-shaped and provides an easy change of the axle while taking care of the 'bearing-job' as well as enabling the axle to position itself precisely. This may be applied to all LGB engines.  Even for those engines where the motor block is very worn out and would need an exchange motor block which is not available any more. Even in this situation the bronze bearing treatment can be applied and will save many a historic and valuable LGB locos.

The finished product

The Result: 
Super"food" for super operating locos! Take note: your general average LGB loco, made in Germany, is constructed to run for 800 to 1200 hours in her lifetime no matter if she runs literally 24/7 or 2 hours on Christmas morning. That translates into just 125 days at 8 hrs of continuous operation per day. Klaus gives you 5800 hours of continuous operation!! Which equals 5 - 8 times the life span of your engine. Price: US$95.00 for the bronze bearing treatment plus installation workshop hours according to locomotive type.

A Note About Wear and Tear: to fight wear and tear on mechanical components regularly calls for grease. Grease is needed within the motor block starting from the worm gear of the motor through an intermediate gear if present down to the plastic driving gear wheel on the axle. Few people are aware of the fact that metal loco wheels and power shoes need to be greased as well. Putting some lubrication on the tracks will double the life expectancy of loco wheels and power shoes instantly. Once the nickel plating on the wheels is gone the rest of the brass wheel will disappear even faster. So do yourself a big favor and add a little grease  e.g. "W D 40", on to the track. Klaus recommends to spray about one (1) foot of the track about every 150 feet once a week. The wheels of the train will carry the lubricant around the layout.

Watch out for:
Over the years Klaus received quite a number of locos for repair due to faulty mechanics work. To help maintain the value of your LGB loco watch out for these:

avoid household glue to "re-place" broken parts

check on easy signs for faulty wiring like flimmering lights after repair

experiencing a short in your loco right or shortly after repair 

rattling noises coming from inside the loco

Please call before shipping an LGB engine to Klaus. It is best to use the original LGB box the loco came in. But you still have to ensure that the LGB loco CANNOT move at all neither within the box nor inside the package the box is transported in. To pack properly, please call Klaus upfront to re- confirm proper way of packaging. Even slightly loose locos inside the original Styrofoam box can be heavily damaged during shipping/transport. Klaus offers professional specialty packaging which ensures very safe shipping.
