Filters, air, oil and fuel
The air filter for the 1992-98 900ss/851/888 is the same as fitted to a Porsche 924. Dimensions are: 211 x 211 x 57. Purflex A515 (K & N equivalent: 33-2003, Mann-Hummel filter part number P12210).
Fuel filters: BMW K100RS part number: 13 32 1 461 265 (8mm) or 16142325859, Purolator F20011, AC GF61, Fram G2, Motorcraft FG-2, Wix 33032, CarQuest E2036 (mid-80's Ford Ranger. Fram part number G2). For the 916: Mahle KL 24/1, approximately 10-15 mm longer than the stock item, it has a 50mm diameter.
The 1994 750SS has a FIAAM FT 4648 fuel filter fitted as standard, here are some equivalents; A.L. ALG-6/8; Lautrette ELE1990; Chamption L101; Purolator F57608; Ryco/G.U.D MF-1; Fram G 12-1; Tecnocar B 7; GIF ES 77; UFI 31.001.00
Oil filters for belt-drive engines: same as fitted to Citroen 2CV & Peugeot 205 & 309 - UFI part number (23.105.00) corresponds with; AC Delco FX0011 (was X4A); Motorcraft EFL 47; Champion H101; NAPA: 1352 (1352NAPA and 551352 on the box); Cooper Z64; Powertrain FL125; Fiaam FT4654, FT 4847 or PA7059; Purflux LS187; Fram PH6074 (was PH2839, PH2864A); Purolator ML16829C (was FC 103 or OC 5); Halfords HOF216; Tecafilter Ref OC5; K & N KN-153; Technocar R12, R72, R434; Knecht OC 5 (equivalent to Ducati #065149960 and #090549960); TJ FB2094; Mann & H W712/9, W712/11; Unipart GFE 201.
Before using any of the above please be aware, early 650 Cagivas with Ducati engines sometimes do not accept the 2CV car filter, the threads differ. In this instance you will probably find that the following 3/4" UNF thread) will fit;
TJ filters: FB5311 and Fram: PH4482. The Fram filter is slightly longer and means you have to leave off the sump guard (Elefant), or make spacers.
Oil filters for bevel-twins: made by Meiwa for Kawasaki KLR250 & Z250 (Kawasaki part no. 16099-004 = Champion X310 and Fram CH6070) FBN OL1.01403.
GT Replacement Air Filters - 0615.27. 275 * FIAAM FL 6179 * FIAT Part # 4110530 * RYCO A134
The fuel vent check valve for the 900ss (and others, possibly, which Ducati sells for $90 or so) can be sourced from a 2008 Kawasaki KLX450R and can be purchased new from Bikebandit.com for $11. It is plastic, not aluminum, but is the same shape and size, and is a nice dark grey.
F1/Laguna Seca/Paso filler caps - original OEM supplier to Ducati for the was Newton Equipment.
The cap is the Aero 400 range. You could contact Newton Equipement : Aero 400 A48S/L
The seal is just a round buna-n O-ring, you could just get it at a O- ring supply house.
Brakes & Wheels
Recent model 900 SS bikes have the same size front brake disc rotors (320mm) as the Yamaha XJ1200, FZR1000 Exup and Genesis, YZF1000, FZR 750 Genesis, SZR 660 and TZR 250 but check that the Yamaha carriers have the same offset as the Ducati carriers.
Spiegler floating brake discs 300mm, are the same for: Yamaha TRX 850, 4KN, 4UN, TDM 850, 3VD, 4CM, FZR 600, 3RH, 3HE, FZR 600 R, 4JH / MH / MM. Once again, check that the disks have the same offset as the Ducati carriers
Ducati 907ie Brakes, ZDM906PI2, 900SS Bj. 88-90, ZDM906SC, Moto Guzzi 1000 Daytona Type KL.
Brembo front brake handlebar assembly - Yamaha FJ1200/FZR1000, Kawasaki ZX7-6 (Nissan remote reservoir, 5/8 inch (15.9mm) part number 43015-1392), Suzuki GSXR 750/1100 1990 to 1996, Honda CBR 900.
Grimeca 180 mm double-sided front drum brake from the early Benelli 250 2C (or equivalent Moto Guzzi 250) is the same as the later Ducati singles. The lugs on the fork where the torque arms engage appear to be identical to those on the early Ducati forks (the one with metal gaiters of the MK3 and the one with rubber gaiters of the SCR). Since the bolts that hold the mudguard are very small (6 mm) the torque arms embrace the aluminium lug behind the bolt and are kept in place by the mudguard's lugs.
Paso speedo drive hub: same as Aprillia RS125.
WHEEL BEARINGS - for 18 inch Borranis and FPS alloy mags
SKF 63004-2RS (size 20 42 16)
BRAKE PADS for F08: (Brembo) D=07.2256.30
Galfer 013 G1532
Carburettors and fuel system
Parts for Mikuni 38 mm constant pressure carburettors mounted on current Ducati models such as the Monster or Supersport are also available at Yamaha dealers because the TDM 850 uses the same. Rubber inlet "pipes" for the carb to manifold junction on the 750F1 or 36 mm
89 900 and Paso with Webber carburetor, parts and overhaul kits are available from auto shops, also high velocity air filters to replace the standard air boxes well as the small filter to fit the crankcase breather.
Paso Dellorto carb conversions. Ski-Doo/Bombadier Snowmobile part # 570-134600 is a near perfect match, the important internal "rubber washer" that mates the carb and manifold is spot on.
888 engine speed and position sensors - Fiat Tipo SEN 8D
907 ie. throttle position sensor (potentiometer), type PF09, is also used in Alfa Romeo 33 ie
Fuel pumps: Ducati 888 item made for Ducati by Walbro (their part number 5CA305-3 (or 5CA305-2 for the white box).
906 Paso: Facet FSE574A. 907ie: Bosch part number: 0 580 463 999.
Bevel friction plates - Suzuki GSF400
Clutch hub bearing: 6201 32 x 12 x 10 (OD, ID, thick). Get a 2RS/1C3. It's a standard electric motor bearing, sealed on both sides.
Clutch slave piston seal: "Quad Ring" part number Q4210-560ND I believe that they need to be made of ethylene propylene (EP).
There is also a Honda part that will fit, part number: 06431-MA3-405. Sorry, I have no information as to which model it is from, it is a square-section seal.
Clutch thrust bearings: If you have a dry clutch with a 28.5 mm diameter piston fitted with a ball race for the thrust bearing, you will probably find that SKF bearing 630/8-2RS1 will fit, sizes are:
Outside diameter: 22 mm
Inside diameter: 8 mm
Width: 11 mm
Late bevel fuse box - 'Durite' with spade fuses for direct replacement, part number: 0234 24.
Front brake light switch (hydraulic) for older models can be replaced by a brake light switch from Volkswagen (Beetle for example), Audi etc. The only difference is the threads, which are conical which means that the washer is not needed.
Oil pressure switch for some early belt-drive late models - Volkswagen Polo. For newer Ducati models (original Ducati code 539.4.030.1A and 539.4.019.1A) - Opel Agila 1000cc. The General Motors code is 90.534.902.
Paso 750 and 906 Marelli ignition coils appear similar to first model of Fiat Uno.
Paso Digiplex ignition unit appears similar to that fitted to Lancia Thema 16V, Fiat Croma 1600 & Moto Guzzi Nevada 750.
Regulator/rectifier - Honda CB250/400N Superdream, CM450 or CX500 (Shindengen part number: SH 232 127 - for many non-fuel injected Ducatis).
Starter solenoid and flasher relay for two-valve twins - Rover/British Leyland Mini/1100
The coils on the Kokusan electrics on the Montjuich, Laguna Seca and Santamonica are the same as on the Suzuki 400 GSX E.
BATTERY - electric start twins:
Westco SVR20 sealed gel battery is smaller than stock, 18 AH, 300+ CCA
Darmah battery - (same dimensions as fitted to Reliant Robin) Varta 53030 12v 30 AH 180A - Sears Die-hard Gold, garden tractor battery, 96135, Group U1, 325 CCA.
Darmah starter motor brushes: (BMW?) part number SBR 5830
Hailwood Replica (Mille) starter motor - Suzuki GS400-425-450 or 500 models.
Monster starter relay: Hella 4RA 003 510-131.
Paso starter solenoid (standard fitment) = Hitachi 12V MS 5A-181.
Bevel-twins sprag clutch: Rover car part number is 22A716. Please note that the outside diameter of the cage that holds the segments together needs to be turned down to 65.5mm.
900ss, 906 Paso, Pantah engine starter sprag clutch: LC4 Freewheel bearing KTM Part No.58440026000. I just fitted one of these to the 906 Paso project, and it cost less than half the price of the original Ducati part.
Darmah headlight: a little cheaper as BMW H4 headlight glass /seal /rim.
Indiana headlight: Yamaha Virago 535 and V-Max 1200
89 900ss headlight can be replaced with a Hella Halogen insert part No. 1042 (or 1042a if you wish to have a parking globe)
Monster headlight glass: BMW R100S, part no. 63121358147. Bosch part numbers for Monster headlight glass & reflector (not available separately from Ducati) are 1305604904 (Glass) and 1305304903 (Reflector)
Pantah light lenses: the front flashers built in the fairing are the same as mounted in old Fiat 850's front bumper.
Tail light for Pantah 500 and 600 models are the same as mounted on former Puch 50cc mopeds.
Paso headlamp: Yamaha FZ750 of 1985/6 - Koyoto part number 110-31420
750 Paso, 906 Paso, 907 i.e. Ducati Part Number 037032600 Headlamp Make CEV
907 i.e. Ducati Part Number 037032210 Headlamp Make Koyoto
Paso 906/ 900 Supersport timing belts (round tooth) = Gates powergrip 5297-070x18mm.
Valve Adjuster Nuts & Bolts (860/900cc non desmo heads)
Vite registro (screw) ~ D=0500.92.660 - Porsche 901.105.370.02
Dado esagonale (nut) 8MB x 4 ~ D=0062.54.241 - Porsche 999.034.005.00
750 VALVE STEM SEALS: D=0755.92.150
The black valve stem seals with the circular springs and firm sides from the first 500 bevel twin motors can be replaced by a General Motors part GM 902 15296. These are a perfect fit on the longer exhaust guide, but need a little bit of sealant on the shorter guide to ensure adhesion.
COUNTERSHAFT SPROCKET NUTS - all bevel twins:
GUK7 SKF nut. Itís a nylock version - get rid of the tab washer.
Another option; It's a standard locknut, as made by bearing companies. Part number (FAG) is KM7 The associated locking tab washer is MB7
More Info: KM7 sprocket nut (Ducati p/n 0755.16.055) is used on GT, Sport, squarecase SS & Darmah. 900S2 and Mille have different number (76800.3380). I don't know what the difference is. The same lockwasher MB7 is used on all. Looks like KM7, MB7 are universal bearing company codes: SKF & FAG both use them.
OIL PLUG WASHERS - all bevels: M22mm standard copper oil drain plug
Handlebars, switchgear, instruments and mirrors
916 handlebar plugs are much more expensive (but identical to) 600 Monster equivalents.
Bevel Drive 900 models (Darmah, Darmah SS, SS) with Nippon-Denso handle bar switchgear is the same as on similar year GS series Suzukis.
Handlebar switches on the current SS models - Honda XBR500.
Right-hand handlebar switches for 748/916 - Honda Fireblade
Mirror assemblies for the current SS models. Honda CBR600 is also a close fit.
For the M900/M600 'Busch and Muller' part number BM926/37, similar appearance and better visibility. "Baby Turbo" made by Vitaloni are another alternative. Emgo mirrors for some Kawasaki ZX models will fit.
For the Paso and 907, mirror assemblies from the Cagiva freccia C12R will NOT fit. Although they look similar, they are NOT interchangeable.
750 Sport Instrument clamps - 1980 BMW automotive air cleaner intake hose clamps.
750 GT Handlebars - Magura Eurobend BMW style handlebar.
Paso clock can be replaced by fitting the printed circuit board from some Fiat models such as the Mirafiori, Tipo and Jaeger.
Paso ignition switch - Gilera 125 SP01
Ducati key blanks - Moto Guzzi (Zadi), Vespa or Kawasaki also worth trying Fiat key blank number FT-37 (was: F79-1). Yugo: (Ilco # YU2 X167 for boot/trunk), S2 key blanks; steering - Silca ZD11P, ignition - Silca AF5D, seat lock - Silca NE31. For the Darmah: Taylor blank # F69H or F69F. For 1980 900SS: ILCO (made in Canada) F91H/F69H (Original key says "BG" on the rubber part and "H3" stamped on the key itself. For the 750 Paso: JMA F161 (ignition) & Silca CE7 (seat). For the 906 Paso: Ilco FT46 X152 (ignition) and Ilco 9978 (seat). For the 907i.e. A blank from a 'Hinckley' Triumph has worked OK.
Paint (touch-up): early belt-drive SS models - Ford Radiant red or Hycote Nissan red 526. 748 yellow: Colorite 7560U. On the official Ducati website the colour is listed as PPG 473.201 (PPG is the US based manufacturer of the original paint), very close to Fiat 268 (Giallo Bus). From Lechler in Italy: red 906 Paso (1989): Rosso 65205
Suspension and steering
Fork seals for Showa GD011 equipped bikes are standard 41mm ID x 54mm OD x 11mm seals as found on Suzuki RGV250 (1991 onwards) and Honda NX650. The rear suspension unit for the 750F1 shares its dimensions with the 748/916 unit.
Up-side down fork bushes (inner fork leg diameter is 41 mm), the bushing that goes on to the inner fork leg (slide bushing?) = Suzuki part number 51121-28C00 (Suzuki GSXR1100 '90-). The one that sits in the outer fork tube (guide bushing?) = Suzuki part no. 51152-08D00 (Suzuki GSXR750 '92-'93).
38mm Ceriani FORK SEALS: (Ceriani) 0540.78.360
YAMAHA YZ-250 3EN-231 45-00 or YZ-400 1W4-23145-LO
these are non stock replacements - 38 x 50 x 8 so use ONE per leg not two
38 x 50 x 7 is original, use 2 per leg as per original
38mm Ceriani fork seal retainer circlips:
'86-'87 Honda VFR 700 or '87-'90 CBR600 - easier to remove and install than stock
