XJ PARTS CATALOG, SECTION K: STEERING/SUSPENSION

SECTION K:

STEERING HEAD BEARINGS:

OEM and aftermarket steering neck or "tube" replacement bearings bring that brand-new feeling back to your bike, improving handling, braking, and steering performance that has been reduced over the year by wear and tear on the bearings and related parts. We offer both the original Ball Bearings and parts for models so equipped, as well as aftermarket Tapered Roller Bearing Kits needed to upgrade this critical area to the most modern design.

Does your bike need new steering head bearings?:

Is this you?:

- "Basically, I am getting a nasty death-wobble at speed on my bike. How can I tell if the steering head bearings are bad? Head shake?"

Here's how to check your steering head bearings:

a) Place the bike on the centerstand, and have a helper sit on the rear of the seat to put the front wheel in the air.

b) Crouch in front of the bike and grab both front forks toward the bottom.

c) Try to "wiggle" the forks fore and aft; there should be no play.

d) With the wheel still elevated, slowly turn the handlebars lock-to-lock. You should feel no binding, looseness, or "bumpity-bumping" in the bars while turning; it should be free and smooth.

e) From a completely centered position, give the handlebars a gentle push to one side. It should fall to full lock smoothly, without binding. Return the bars to straight (centered) and repeat this test in the other direction. If there is a "detent" or looseness at the center, you probably need new bearings

f) If your steering (forks) "lock" in the centered position, and take a good amount of pressure to get them off of the centered position, then your steering head bearings are either over-torqued, or, more likely, worn out.

NOTE: the factory service interval for the re-packing of the steering head bearings with grease is every 10,000 miles (all XJ550, XJ650, XJ750, and XJ1100 models) and every 16,000 miles on the XJ700 and XJ900RK models. The bearings should be inspected every 2,500 - 4,000 miles for looseness, and adjusted as necessary.

NOTE: all 1992-98 XJ600 Seca II, XJ700, XJ750-X, XJ750RL, XJ900, XJ1100, and all XS1100 models used tapered roller bearings originally; all other XJ models used ball bearings from the factory.

NOTE2: always use a high-quality, waterproof grease when installing any style of steering neck bearings!


Ball Bearings and Associated Parts:

Although we do offer a full selection of original components to rebuild your stock ball-bearing style steering neck system, we highly recommend that you upgrade to the tapered roller bearing style bearing system with one of our Roller Bearings and Seals Kits listed further below.

The only items that interchange when upgrading from the ball bearings system to tapered bearings are the MAIN CROWN BOLT or NUT, the adjuster RING NUT(S), and the UPPER RACE COVER.

Tapered Roller Bearings and Associated Parts:

Both original roller bearings (1992-98 XJ600 Seca II, XJ700, XJ750-X, 1984 XJ750RL Seca, all XJ900RK, RL, N/FN, and F models, XJ1100, and all XS1100 models) and kits to upgrade all other models to this improved style tapered bearings are offered. The aftermarket kits that we offer use only the highest quality, precision ground and assembled high-speed bearings available, and include both upper and lower dust seals.

Tapered bearings offer a vast improvement in performance and durability as compared to stock ball bearings. Additionally, you can increase the ring nut torque value to a slightly higher (25-30 foot-pounds) as opposed to original, thus even further reducing slop and play in your steering. ALWAYS MAKE SURE THAT YOU CHECK FOR BINDING AT ALL POSITIONS, INCLUDING FULL LOCK POSITIONS, WHEN CONVERTING FROM BALL BEARINGS TO TAPERED BEARINGS!

Here is a great video that shows the installation process for these tapered bearing sets:

BEARING TOOLS:

NOTE: SOME OF THE FOLLOWING TOOLS ARE AVAILABLE FOR RENTAL!!: some tools are a one-time or infrequent use tool, so it may be more economical for you to rent them from us, rather than to purchase outright. Please see the “rental” section within the THE TOOLBOX section of our catalog at:

http://xjbikes.com/forums/index.php?threads/xj-parts-catalog-section-p-the-toolbox.44630

and review the availability and procedures in the TOOL RENTAL section.


A cheap and simple method for bearing removal and installation involves heating the bearing (so the ID of the race grows fractionally) while also cooling the shaft (so its OD shrinks). The combination of these two methods can make bearing work amazingly easier:

heating:



shrinking:



These tricks work well for steering head bearing replacement, wheel bearing replacement, tranny gears, etc.



Steering Bearings Tools:

HCP1692 Aftermarket steering head tube BEARING RACE REMOVAL TOOL. This very high quality, split flared-shaft bearing race removal device grasps the edges of the bearing races at four positions and pops them out with ease. Makes a sometimes very frustrating task simple.
$ 44.95


HCP8041 Aftermarket steering stem Ring Nut ADJUSTER WRENCH, special tanged wrench properly grabs the castellations in the ring nuts and holds firm, preventing the rounding-off of the ring nut when trying to loosen or install them using incorrect tools (such as channel lock pliers). Adjusts to a wide range of sizes to fit most bikes. A professional grade tool.
$ 89.95


HCP7863 Aftermarket steering stem ring nut and shock absorber ADJUSTER TOOL, heavy-duty chrome plated spanner "wrench" is the correct size to work with all XJ-series bike steering stem ring nuts, as well as fitting the adjuster tab on rear shock absorbers (for those models that have non-air adjustable rear shocks). Very high quality, versatile tool to have in your box.

Super-Penetrant Fluids and Lubricants:

Sometimes, the toughest part of working on a vehicle is battling the effects of time: seized fasteners, caused by rust, corrosion, and other factors, turns what should be a 5-minute effort into a 50-minute (or more) chore, complete with rounded-off, ruined, or snapped fasteners, e-z outs, heli-coil inserts, and more.........and that's just not right.

While the proper use of our various Anti-Seize products will prevent these nightmares from occurring in the future, you're stuck in the here-and-now, and the best way to handle these obstacles is to have the proper tools at the stand-by; and in the case of fastener seizure, the proper "tool" is a can or two of our SUPER PENETRATING LUBRICANTS at the ready; a couple of squirts, a little bit of time-----perhaps some heat for those really nasty situations----and you're on your way again, hopefully not too much worse for the experience.....

Great for use on all fasteners, fork tube cap bolts, intake and exhaust manifolds bolts, studs, and nuts, lock cylinder tumblers, or anywhere an un-cooperative fastener can be found. Can even be used to help un-seize frozen engines!

Be aware that these products are not your typical, garden-variety, run-of-the-mill "retail" type products; these are designed an used as industrial- and military-strength products, meaning they have special formulations that include a dollop more of the "good stuff" within them to solve the toughest seizure problems imaginable (the "good stuff" ingredients cost more, and it is those compounds that are left out of or reduced in concentration in "retail" level consumer products).

NOTE: the following product(s) can only be shipped via ground transport (which thus eliminates the Priority Mail level of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Therefore it may have to be shipped in a separate package from the remainder of your order, and will thus incur additional shipping charges.

HCP10331 Aftermarket standard-duty PENETRATING LUBRICANT, in a generous 16-ounce aerosol can. Oil-based lubricant penetrates down into spaces of one-millionth of an inch to handle the most reluctant seizures. Actually dissolves the rust and corrosion that causes the seizure; lubricates and displaces moisture to prevent rust re-formation. This product is what we use and recommend for freeing stuck fork tube cap bolts and other such challenging fasteners.
$ 24.95

HCP11974 Aftermarket super-duty PENETRATING LUBRICANT, in a generous 13-ounce aerosol can. Same as our standard-duty formula above, but also includes graphite to not only enhance and speed up the penetrant action, but also gets down into the pores of the metal for the greatest possible lubrication possible. The cat's-meow of penetrating fluids, can even be used to un-seize frozen engines or as an engine assembly lube! This fluid is also a great choice for use as a drive cable lubricant.
$ 26.95

HCP10333 Aftermarket extreme-duty PENETRATING LUBRICANT, in a generous 16-ounce aerosol can. Same as our standard-duty formula above, but also includes liquid silicone to enhance and speed up the penetrant action. This product is also an exceptional choice for use as a control-cable lubricant.
$ 27.95




Assembly Fluids and Lubricants:

HCP8608 Aftermarket gear and bearing synthetic RED MOLY GREASE. High temperature, water resistant, extreme pressure and high-load strength synthetic organic moly grease is far superior to black moly disulfide (petroleum-based) products. Use on steering neck bearings, wheel bearings, starter motor gears, and swingarm bearings. 14 oz. tube.
$ 24.95


NOTE: the following product(s) can only be shipped via ground transport (which thus eliminates the Priority Mail level of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Therefore it may have to be shipped in a separate package from the remainder of your order, and will thus incur additional shipping charges.

HCP20860 Aftermarket industrial-strength ASSEMBLY LUBE, in a standard 12-ounce aerosol can. Heavy-duty formula includes graphite to not only enhance and speed up the penetrant action, but also gets down into the pores of the metal for the greatest possible lubrication possible. Won't wash away, protect against rust and corrosion, stable from 0-degrees up to 250-F. This fluid is also a great choice for use as a drive cable lubricant.
$ 21.95

HCP20862 Aftermarket super-duty ASSEMBLY LUBE, in a generous 10-ounce aerosol can. The cat's-meow of lubricants, infused with pure moly disulfide, it goes on wet and then dries in 1-2 hours to a super-slick, high-pressure, hi-temp, bearing-like finish which provides the ultimate level of protection. Prevents rust and corrosion, won't wash off, throw off, and won't attract dust or dirt. Surfaces must be clean and dry of previous oils, etc. before application. Can even be used as an engine, tranny, and drivetrain assembly lube!
$ 24.95

HCP20863 Aftermarket super-duty GRAPHITE LUBE, in a generous 10-ounce aerosol can. The 800-pound gorilla of lubricants, it's infused with pure graphite, goes on wet, and then dries in 10 minutes to a super-slick, high-pressure, bearing-like finish which provides the ultimate level of protection. Prevents rust, won't wash off, throw off, and won't attract dust or dirt. Surfaces must be clean and dry of previous oils, etc. before application. Can be used as an engine assembly lube, bearing or bushing pre-lube, great for lock cylinders, and all metallic sliding surfaces. Use where dusty or dirty conditions render oil-based lubricants ineffective or undesirable.
