Generator cover

Today I pulled the generator cover off to check the brushes and there was oil in there and brushes looked good.So is that bad and what can I use to clean it.Only about an oz or 2 of oil.

 

Leaking generator shaft seals............yuk! Not a good thing.

Not hard, sorta tedious, you'll need a rotor puller tool, and probably an impact driver wrench to get off the shaft bearing housing. And a factory or aftermarket service manual is always useful!:


ap7) Aftermarket alternator ROTOR REMOVAL TOOLS, correct copy of the factory Yamaha tool needed to remove the alternator rotor from its mounting shaft (the rotor is a friction fit onto the tapered end of the alternator shaft). Designed to be used in conjuction with the HCP6495 rotor puller tool Attachment Tool listed below. The use of these two tools allows you to safely and properly remove your rotor without damaging either the rotor or the rotor shaft. For all XJ550 thru XJ1100 models.

lm1) The ever-popular Haynes or Clymer WORSHOP MANUALS line of "enhanced" factory service manuals cover all major service, repair, rebuild, and maintenance procedures (sometimes in excruciating detail, and usually with many more pictures and illustrations than the factory service manual does), and also includes wiring diagrams and other useful specifications.


HCP1093 Haynes Service-Repair-Maintenance Workshop Manual, for all 1980-84 XJ650 (except Turbo) and XJ750 models, softcover, over 275 action-packed pages, a must-have manual if you own one of these machines. Each:
$ 25.00



lm2) Original reprinted FACTORY SERVICE MANUALS are also available. These full-size manuals covers all aspects of diagnosis, repair, and assembly for specific model bikes. These brand new, official Yamaha manuals are one of those "must-have" tools if you're going to be wrenching on your own bike. Plenty of photographs, diagrams, flowcharts, wiring charts (some of them even being correct!), torque values, etc. NOTE: cover design, color, and appearance may differ from originals.

NOTE: originally, Yamaha would not release a new service manual for each year's production, unless there had been significant changes in design, service procedures, features, etc......and even in those cases, even if there HAD been significant changes, they would not release an entirely new service manual, but merely a "supplement" to the past service manual for that model, and that supplement would highlight only the changes to procedures, etc. that would need to be followed.

For example: the 1980 XJ650 Maxim---being the first model in the XJ650 series---was issued a service manual by Yamaha. The 1981 XJ650 model, having no significant differences from the 1980 model, used the same 1980 XJ650 service manual. However, the 1982 XJ650 Maxim models had a number of meaningful difference in service procedures (first and foremost, the introduction of the YICS cylinder head design and system, which required a different synchronization procedure, a variation to the engine teardwon and re-build procedures, etc.).

Rather than publish a brand new service manual for the 1982 XJ650 Maxim models, Yamaha merely published a service manual Supplement and instructed dealers to use the 1980 XJ650 Base Service Manual along with the 1982 XJ650 Supplementary Service Manual to properly service those bikes.....after all, 90% of the procedures in the 1980 XJ650 "base" Service Manual still applied and were valid for the 1982 XJ650 Maxim models, so why publish an entire new manual, when just a "supplement" would work?

This same process applies to many of the original models and their service manuals. The 1982 XJ750 Maxim models, for instance, used that same 1980 XJ650 Maxim Service Manual as the "base manual", and had a 75-page XJ750J Supplementary Service Manual that was to be used in conjunction with the base (1980 XJ650) manual.

That was then.

This is now: all of the Supplementary Service Manuals are rolled into the front of the "base manuals" for the individual manuals listed as reprints below. So for instance, the 1982-3 XJ650 Maxim Service Manual has both the 1980 XJ650 "Base" Service Manual AND the 1982-3 XJ650 Supplementary Service Manual bound together into one book.....no need to acquire two different books to have all of the correct prodcedures for working on your 1983 XJ650 Maxim. Same thought applies to the XJ750 Maxim Service Manuals.....they have the "base" 1980 XJ650 Maxim Service Manual, and also the XJ750 Maxim Supplementary Manual all bound together into one book.

Some manuals, such as the XJ550 Maxim and Seca Service Manual, will be labelled (on the cover) as a 1981 XJ550 Maxim/Seca Service Manual, when in fact it covers all three model years.

So when you purchase one of the manuals listed below, rest assured that it will have ALL of the correct procedures and information that will apply to the specific models for which it is listed as covering.
