In April 2005 Tomos USA sent “A55 upgrade” kits to dealers, to fix idling and other issues.
2005 A55 engines had trapezoidal (slanted top) piston rings. 2006-on had rectangular type rings.
2002-09 wide-tire-model engines had a dished front sprocket, to move the chain away from the tire.
2010-13 wide-tire engines are moved to the left about 14 mm, allowing the use of a flat sprocket.

In 1996 the carb location changed from center to side mount, making service way easier. 
1974-1997 left engine cases had ∅90 stator plate mounts with three M4 screw holes.
In 1998 the magneto changed to a “4-star” or “plus sign” design AET 11.170.001.
3 of the 4 coils were for lighting, connected in series, and one coil was for ignition.
The wires did not change. The base plate screws changed, from three 4 mm, to two 5 mm.
1998-2002 left engine cases had ∅90 stator plate mounts with both 2 M5 and 3 M4 holes.
In Jan 2003 the A35 left engine case changed. A boss for electric start was added.
The two left cover centering bushes got bigger, from 037062 (5 mm) to 223440 (10 mm).
2003-2013 left engine cases had ∅90 stator plate mounts with only two M5 screw holes.

The 1973 A3 was the third Tomos-designed engine, but was the first widely produced.
Before the A1 and A3, Tomos made Puch-designed engines and bikes from 1956 to 1981.
That’s why some early A3 parts are the same as 60’s Puch, such as the L17 3-piece bearings. 

In 1986 (and 1985 Golden Bullet) the crank bearings changed from L17 17x40x10 to 6302 17x40x12.
The engine cases got 2 mm wider on each side. Servicing was easier and bearings lasted longer.
Also in 1986 the carburetor changed from Encarwi to Dellorto. Servicing became more difficult.

3. Tomos A5 (A35 and A55) engine parts

Here 35 Tomos USA parts manuals are combined into one. Four bike versions (pre-mix kick, pre-mix pedal, oil-inject kick, oil-inject pedal) are indicated by four quantity columns ppoo. Three illustration versions abc show the changes and improvements made over time, from 1992 to 2018, with a being the newest. Newer part versions have higher part numbers, and are listed first (except for ’92-97 magneto).

This is both a spec sheet with applications, and a list of parts for sale. Many things that say “none” in the price are listed for information purposes. The purpose is to possibly find substitutes by knowing the original part specifications. Sometimes parts can have different part numbers, but the difference is something minor that does not matter, or can be adapted. Some folks have parts, or see a part for sale, where the part number is known but not what models it’s for or could fit.

Note 1: The softer red 223769 spring in the #2 clutch on A55 models causes an early shift, at about 8 mph, but sometimes 5 mph, too soon. A green 209013 spring is stiffer and delays the shift until 10-12 mph. Staying in #1 gear longer improves acceleration and hill climbing. But after the #2 clutch shoes get worn out, the stiffer green spring can sometimes cause chattering, shaking the bike violently. That might be why Tomos chose a red spring for the #2 clutch on A55, despite it’s poor performance accelerating and climbing hills.

Note 1: From 1974 to 2007, oil was sealed by metal-to-metal. The flat inner side of the sprocket #17 pressed perfectly against the bearing #22, as long as the nut #19 was tight. Oil leaks there were uncommon. But after 2007 the sprocket center was made wavy, causing leakage.

Note 2: In 2008 Tomos remedied the oil leak (caused by wavy sprockets) by cutting a chamfer in 209077 and adding rubber o-ring 033007. See Service/Tomos/A55 Trans Oil Leak. Many of the first 209077’s were not cut deep enough. They pinched and severed the o-ring when the nut was tightened. The ones offered here are cut correctly.

Drive shaft: The coaxial drive “shaft” is more like a drive “gear”. It is hollow, with the start shaft (pedal or kick) going through it’s center. On a pedal version the center has a ring of teeth. The teeth were made of tool steel up to 2007, and never broke. After 2007 the teeth were made of cast iron, and sometimes broke off. When all the teeth break off, the bike can still be started with a backwards kick, but the pedals move forward freely and do not propel the bike. That’s not so bad, but the iron chips in the oil can damage the gear teeth, sometimes catastrophically. Once the chips are cleaned out the bike can have a normal life with motor only.

Note 1. The ratchet block slides side-to-side to engage or disengage the pedals. It has a “ring of ramps” on the right end that engages when pedaled backward, for kick starting the engine. On a Tomos pedal model, the ratchet block also has a left ring of ramps that engages when pedaled forward for pedaling. On a kick model ratchet block does not have a left ring of ramps.

 Note 2. The A5 (A35 and A55) internal pedal chain and sprockets are wider than A3 ones. A5 has a 3/8 x 3/16 32 link chain ANSI#35. A3 has a 3/8 x 5/32 32 link chain.

Note 1. The generic magneto #230842, original equipment on all 2009 Tomos bikes, has a pulser coil. The India M1100000 replacement magneto, also #240842, does not have a pulser coil. The replacement 230842 is the same as no-pulser AET 11.170.017 magnetos #230842 on 2002-04 A35 Revival and 2005 LX Limited. Tomos re-used a 2002 part number on a 2009 item that was not interchangeable. The external pulser is separate from the internal stator and can be replaced separately. But the flywheel needs to have the raised outer strip that triggers the pulser. The original equipment 2009 flywheel does, but the replacement with the same part number does not.

Note 2. The ground wire is important. It prevents damage to the electronic ignition if the engine becomes loose in the frame. The high voltage sparks that jump the gap of the spark plug have to go to the frame and then back to the coil to complete the circuit. When the engine is loose with no ground wire, there can be sparks between the engine and frame. Or sparks can jump from the engine case to any nearby engine wire that leads to the frame, including the electronic CDI unit wires. 

Note 3. The Ducati Energia India CDI-coil for A55 has a history of failure of roughly one out of ten. The rev limiter sometimes happens at a very low rpm instead of very high. On some the bike will only idle or go slow, and misfire and cut out otherwise. On some it will be intermittent spark, where the engine runs for maybe a second and then cuts out. Having a resistor plug and/or a resistor plug cap, and an engine to frame ground strap helps prevent electronic failure. Because of the failure rate, the Ducati Energia India CDI-coil is only sold without any guarantee.

Note 4. The generic Taiwan CDI-Coil for A35 has not been evaluated. It is not known how long it lasts or performs. Because of that, it is only sold without any guarantee.

Plus sign type stators came out in 1998. The 4 outward facing coils were composed of three lighting coils in series and a separate ignition source coil. This is two independent generators, lighting and ignition combined into one unit. The volts and watts refer to the lighting output.

Left engine case determines what magnetos could fit. See photos and details in section 2.1.
’74-91 A3, ’92-97 A35 left case had only 3 M4 stator  holes. It can only take a 3-bolt 94 mm stator.
98-06 A35, 04-07 A55 left case had 3 M4 and 2 M5 holes. It can take either 3-bolt or 2-bolt stators.
’08-18 A55 left case had only 2 M5 stator plate mount holes. It can only take a 2-bolt 94 mm stator.

Flywheel nuts before Jan 2003, for oil injection, had two prongs that turn a edge-slotted aluminum disk. The disk also has a center slot that turns a tongue on the oil injector pump. This “floating” disk allowed for a small amount of misalignment between the crankshaft and oil pump shaft centerlines. After several thousand miles the soft aluminum center slot wears out and becomes hour-glass-shaped. It should be monitored and replaced before it becomes completely rounded out. When that happens it’s “game over”, as the lack of engine oil causes seizure and damage. 

Flywheel nuts after Jan 2003, for oil injection, had the floating disk rubber-mounted to the nut. These were all well-made until about 2009, when some, but not many, were made off-center. Those would prematurely round out the center slot, causing the oil pump to not turn and then the engine to seize.

Left, AET flywheel with 222304 nut, no washer.
Right, IDM flywheel with same nut, no washer
This shows IDM center hole is 1.8 mm deeper.
Also a thick washer is needed for socket wrench.

IDM flywheel nuts: Most moped flywheels have a threaded center hole for a flywheel puller tool. IDM flywheels have smaller center holes with M19-1.0 threads instead of M26-1.5. The nut and washer have to be smaller. But there is no room for a socket inside the threaded hole. So the flywheel nut has to be at least 14 mm tall. Then it sticks out at least 5 mm past the edge of the flywheel, enough for a socket or wrench. The crankshaft ends at the edge of the flywheel. So simply adding washers or a spacer behind the nut is not possible.

IDM flywheel nuts: Besides the flywheel center hole width, the depth is also different. CEV/IDM flywheel center holes are 1.8 mm deeper than AET/Iskra/Bosch/Ducati flywheel center holes. This only matters for oil injected models, where the nut turns the oil pump. Because of that the IDM flywheel nut needs to be 1.8 mm taller than the AET/Iskra one.  In fact it is almost that, 10.5 minus 9.0 is 1.5 mm.

Iskra logo

AET logo

Iskra and AET are the same: In the mid-1990’s the Slovenian-made Bosch-compatible magneto-generators on Tomos mopeds changed names, from Iskra to AET. AET is one of the Hidria group of companies, along with Tomos. Both names are sometimes used interchangeably. On some magnetos, the stator plate says Iskra, but the flywheel says AET.

Corrections: 

In the diagram b, from the 96-97 Targa catalog, the lower ignition source coil part number is incorrect. It says 229518, but it should be 229528. This version here has been corrected.

In the IDM 6411 diagram e, from the 96-97 Sprint catalog, the stator plate part number is incorrect. It says 221471, but it should be 229471. This version here has been corrected.

Also in diagram e, the flywheel washer part number is incorrect. It says 229919, but it should say 212842. 229919 is too wide to fit there. This version has been corrected.

Also in diagram e, the flywheel nut for IDM 6411 with oil injection has an invalid or unknown part number. It says 229629, but that number is not in the Tomos USA 2012 list. It should say 222304, like IDM 6436 has. This version has been corrected.

In the IDM 6436 diagram f, from the 93-95 Sprint catalog, the flywheel washer part number is incorrect. It says 031934, but it should say 212842. 031934 is too wide to fit there. It’s 18 mm OD but the M19-1.0 internal thread tops are 17.5 mm ID. This version has been corrected.

In the diagram c from the 93-95 Sprint catalog (diagram Eb for oil inject) the flywheel nut part number is wrong. It says 222304, but that would be 1.8 mm too tall for a Iskra/AET flywheel. The correct nut is 217487. This version has been corrected.

Here 8 Tomos USA parts manuals are combined into one. Four bike versions (pre-mix kick, pre-mix pedal, oil-inject kick, oil-inject pedal) are indicated by four quantity columns ppoo. Three illustration versions abc show the changes and improvements made over time, from 1975 to 1991, with a being the newest. Newer part versions have higher part numbers, and are listed first.

This is both a spec sheet with applications, and a list of parts for sale. Many things that say “none” in the price are listed for information purposes. The purpose is to possibly find substitutes by knowing the original part specifications. Sometimes parts can have different part numbers, but the difference is something minor that does not matter, or can be adapted. Some folks have parts, or see a part for sale, where the part number is known but not what models it’s for or could fit.
