MiscRes: Harley and Buell Technical Service Bulletins (TSB), (B)


See the Misc Resource Section on the Sportsterpedia main Tech Page for a list of P&A Bulletins, Tech Tips etc.

  • The following Technical Service Bulletins were issued by Harley-Davidson to their dealer network. To the best of our ability, these bulletins have been displayed as issued. The Sportsterpedia is displaying these bulletins as PDFs for information only. End users are fully responsible for the results of evaluating and using this information. The Sportsterpedia makes no claims of accuracy, applicability or authentication of the information presented in these bulletins.
  • Ever wonder just how many Service Bulletins were issued for Sportsters? The difficulty is that there was no numbering system involved to distinguish the separate models. Hence, the bulletin numbers related to all HD models skip around. A list of 'to date available' bulletins were published from time to time in the form of a Service Bulletin.
  • Below is a list of known Service Bulletins from the MoCo. More will be added when discovered. Those related to Sportsters or All Models are highlighted to be more searchable. The complete list also shows you what other issues the MoCo was dealing with at the time. 1) 2) 3)
  • The header block on the top of the bulletins includes HD branding, bulletin number and date of issue. Some bulletins have AMF branding even before the date that AMF took over the company. TSB #458 explains that older bulletins (reprints) could be requested by a dealership and gives a listing of those available at the time. This may be why there are a few pre-AMF bulletins with the AMF logo in the header block (old bulletin reprinted and branded by AMF). TSB #597 shows both headers for that bulletin as example.
  • Note that you can create a PDF of this page (with our listing of TSBs). CLICK on the 'export:pdf' in the menu tabs at the top of this page. Then choose to 'save' the file to a convenient location. You can then print your PDF as a booklet.
  • The Table of Contents will allow you to jump into the middle of the listing.
  • You can search the page using Ctrl-f. Ctrl-Home will take you to the top of the page - Ctrl-End to the end of the page.
  • These files open best when using Adobe Reader. On some PDF viewer programs other than Adobe, they may not open properly. Click here to download the latest version of Adobe Reader. You can also find other PDF viewer programs on the net that will open them. Some of the bulletins have a security lock from editing them but all will open for viewing in Adobe.
  • When you click on one of the PDFs, Adobe Reader will load and proceed to download the chosen bulletin.
    This could take some time on slow connections as some of the bulletins are larger than others.

which were assembled with substandard rear caliper piston 0-ring seals.
663 Y 4-29-1974L1974 XLH/XLCHClutch Changes
Notes: Late 1974, clutch changes include;
New pressure plate with six spacers between the pressure plate and the releasing disc,
A conversion kit was available to convert 71-E73 models to the new 74 style set-up.
664 Y 5-29-19741974 SX-175Fuse
Notes: Through a production oversight, the fuse was not installed in one of the fuse holders
of SX-175 models produced at the York plant shipped before Apri1 26, 1974.
665 Y 6-10-19741973 Z-90Front Brake Sideplate
Notes: New sideplate has heavier material and therefore is supplied with a thinner axle spacer.
666 Y 7-10-19741974 SX-175Capacitor Discharge
Ignition System
Notes: The breakerless capacitor discharge ignition system used on the SX-175 models
consists of a charging coil inside the alternator rotor and two external triggers with a
pick-up coil. Also in the system are an ignition switch, ignition module, high tension
coil, and spark plug.
667 Y 6-21-19741974 SX-175Air Cleaner Care
Notes: The air cleaner not only needs regular attention to maintain operating efficiency,
but under dusty operating conditions will require additional measures to prevent
entry of dirt into the engine.
668 Y 8-26-19741974 SX-175Front Wheel Tire Bead Clamp
Rear Brake Sideplate
(Recall 025)
Notes: On models within VIN ranges listed;
One of the two front tire bead clamps was not installed on SX -175 models.
Rear brake sideplate has insufficient strength in anchor bracket stud mounting area.
1973-1974 XLH/XLCH
Ignition Coils
Notes: Through a supplier error, an unknown quantity of ignition coils were mislabeled
as 12V coils but were actually 6V coils which possibly affected some of these models.
670 Y 10-7-1974SX-175Exhaust System Cleaning
Notes: A gradual reduction in power after a period of service on 2-cycle engines is most often
caused by exhaust system restriction from a buildup of carbon deposits. This bulletin
details instructions on how to remove these deposits to restore engine performance.
671 Y 10-7-1974Late 1975 SX-175Rear Wheel Spokes
Notes: A positive retention of rear wheel spokes in the right side hub flange was done by using
washers underneath the spoke heads. As an interim change, some early 1975 models
have nylon plugs between the spoke hooks in each slotted hole to accomplish this.
672 Y 10-9-19741974-E1975 SX-175Carburetor Modification

Notes: A non-chromed cast iron oil control ring is being substituted for the chrome plated type
for all 1975 production 1200 cc engines and for parts order pistons, ring sets,
and cylinder assemblies.
674 Y 10-14-19741974 X-90/Z-90Air Cleaner & Carburetor
Notes: Excessive plug fouling and poor overall performance may be the result of an over-rich
fuel/air mix caused by a restricted paper type air cleaner element or too large a main
jet for operating conditions.
675 Y 10-14-1974XLH/XLCH/FXIgnition Switch
Notes: Due to a production oversight, lubricant was omitted on the ignition key switch indexing
plate which could cause the switch to bind up. This bulletin gives instructions on
lubricating the switch.
676 Y 10-14-19741974 FX/FXE-1200Jiffy Stand Support Plate
Notes: A support plate has been added to these models to eliminate possible bending at the
Jiffy Stand mount.
677 Y 10-14-19741975 FX/FXEFoot Shifter
Gear Timing
Notes: Through a production error, foot shifter gear (33960-74) on most E75 FX/FXE 1200
models will have an improperly located timing mark stamped over to obliterate it
and another mark stamped between the next teeth in the correct location.
678 Y 12-17-19741974-1975
Rocker Arm Covers “M”
Notes: A number these models were produced with modified rocker arms and rocker covers
machined to prevent interference between the rocker arm and the inside of the rocker
cover due to a thickness variation in the covers.
679 Y 12-17-1974X-90High Voltage Problem
Notes: Premature light bulb failure on the X-90 can be caused by excessive voltage. With
the headlamp on and the switch in the low beam position, check A. C. voltage at
the headlight.

includes a special crankcase retaining screw.
682 Y 1-31-1975SprintSpoke Maintenance
Notes: Previous bulletins (441 & 535) stressed the importance of maintaining correct wheel
spoke tension on SS/SX -350 models to prevent loosening and possible spoke
breakage. Since we've received reports of progressive wheel spoke breakage, esp. on
SX -350 models used severely, We are again emphasizing this important item of
preventive maintenance.
683 Y 1-31-1975X-90/Z -90
Throttle and
Brake Lever Support
Notes: In the past it was necessary to replace the complete support assembly. Now it is
possible to reuse the throttle and brake lever support by modding and adding this
kit (45186-74P) to the lever support.

Notes: An insecure assembly resulted from using 3“ long handlebar mounting bolts on the
Liberator Fairing on 1972< FL/FLH. This must be repaired with 3-1/2” bolts (93141).
686 Y 4-8-1975XLH/XLCHTransmission
Notes: Reports of XL & XLCH transmissions with a blocked oil transfer hole in the trapdoor.
(resulting in little to no oil supply to the transmission)
Also, between December 16, 1974 and January 7, 1975;
A total of 63 mainshaft low gears were installed in XL/XLCH transmissions without
prior heat treatment which gave to noisy gear movement due to accelerated tooth wear.

Around the oil passage between the upper crankcase cover and the crankcase.
Since November of 1979, the crankcase castings have been reworked and modified to
eliminate this possibility. As a part of that revision, the crankcase cover gaskets used in
production and in stock have been modified to not only fit the revised castings but also
to eliminate the possibility of oil leakage on earlier crankcases.
