XJ900 MODELS FORK TUBE PARTS:

NOTE: items marked below in red are the parts typically needed when doing a basic fork system rebuild.

A good visual review of the procedures needed for rebuilding these forks can be seen at:

http://xjbikes.com/forums/index.php?threads/4067

Note that this link shows the guts on the later XJ900 models fork systems (without the anti-dive system), but is pretty much the same as on the earlier versions with the anti-dive system.

The secret workings of the anti-dive units can be seen at:

And these incredible 3-D renderings of the inner workings of a forking system gives a great visualization of the internal components (it is based on the 1982-83 XJ650 Maxim forks):

NOTE: XJ750 Police (37H models) used the XJ650 Turbo master cylinder with XJ650 Turbo/XJ750 Maxim/Midnight Maxim calipers, XJ650 Turbo rotors, and XJ900 style forks with anti-dive.



FORK TUBE REBUILD KITS:

We now offer both a BASIC FORK REBUILD KIT and PERFORMANCE FOR TUBE REBUILD KITS so that you can get all the typically-needed rebuild parts under one simple part number. Each kit is specifically assembled and correct for your particular model bike. NOTE: fork rebuild kits do not include any of the items used in rebuilding the anti-dive units; a separate kit to rebuild those is available as part HCP21992 and is listed in the anti-dive parts section further below.

- NOTE: the lower tube “dust boots” (sometimes called dust seals) are not included in the basic fork tube rebuild kits, but are available separate and can be found further below.

Basic fork rebuild kit contains at least the following items:
- cap bolt o-rings.
- standard quality lower fork tube oil seals.
- oil seal retaining clips.
- oil drain screws and gaskets.
- damper rod bolts and crush washers.
- damper rod head piston rings.
- air joint cushions, o-rings, and retaining rings (in the XJ900RK/RL kit).
- air valve cores (in the XJ900RK/RL kit).
- anti-dive housing to fork tube o-rings (1983-84 kits)

Inner Tube Fork Springs:

NOTE: the following springs are correct for the XJ900RK and RL models, XJ750RL (44X Canadian and 45T Australian models), and will also fit the XJ900 N, FN, and F model fork tubes, but we do not have the information for the non anti-dive forks in regards to spring spacers or oil fluid capacities required. Original non anti-dive fork springs (XJ900N, FN, and F models) are 5mm shorter than anti-dive springs (XJ900RK and RL), so it is safe to assume that a 5mm (or greater) spacer may be needed, and the oil level adjusted to achieve a 168mm height.

HCP9439 Aftermarket front suspension COIL SPRINGS, one pair does both forks. For all XJ900RK, XJ900RL, XJ750RL, XJ1100, and all XS1100 models. No spring spacer is needed when using these springs on the XJ900RK and RL models. NOTE: due to the difference in size of this spring versus stock springs, you will need to use approximately 31 cc's less fork oil (for a total of 255cc's per tube on the RK and RL models, and 276cc on all other XJ900 models) when installing these springs, or adjust to a 164mm oil level. NOTE: springs should be installed with the tighter (more-closely spaced together) coils towards the top of the fork tube.

Lower Tube Anti-Dive Unit Parts:

The front fork ANTI-DIVE SYSTEM on these models are almost always in need of a complete, thorough cleaning and rebuild. While many people claim that the anti-dive system is a "useless" feature, the real reason may be that the system is so internally fouled and seized that it simply is not operating, at all!

Anti-dive control units are divided into an "upper" (or "top") section, which is the brake plunger assembly....this upper section is where the brake hose, from the brake caliper, attaches. The brake fluid BLEEDER VALVE is located in this upper section, as well as the brake plunger piston unit. The O-RING on the plunger and on the screw-in piston head should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. The removal of the piston head requires the use of a special reverse-hex tool, part HCP16049.

The "lower" (or "main") section of the anti-dive unit is the larger damper piston assembly (which is bolted to the fork tube), and which contains the damper actuating piston and spring. Under hard braking, the brake fluid pressure forces the brake plunger (in the top "brake plunger assembly" section) to push down on the damper piston and its spring, restricting the flow of fork oil in the fork tubes, thus "stiffening" the fork system temporarily----and reducing the amount of front end "dive" during hard braking. The O-RING on the plunger should be replaced during a rebuild procedure, as well as a thorough cleaning and polishing of the piston bore. And the housing-to-fork tube O-RINGS should also be renewed.


Here's a good view of the components of the lower damper piston assembly on the XJ750-D, XJ750P Police (37H model), and XJ900RK and RL models anti-dive unit can be seen at:

http://xjbikes.com/forums/index.php?threads/44997

NOTE: to dis-assemble the brake plunger assembly piston for cleaning and replacement of the o-rings, you will need this special tool to extract the threaded plug from the housing:

HCP16049 Aftermarket fork anti-dive brake plunger assembly REVERSE HEX SOCKET TOOL. This tool allows the easy removal and installation of the "inverted/reversed" hex-drive plug used on the top of the anti-dive units on all XJ750-D, XJ750P (37H model), XJ900RK, and XJ900RL models.
$ 14.95


NOTE: if you want to disable your anti-dive system, you will need to remove the hose from the caliper to the anti-dive unit (and replace the caliper end double-depth union bolt with the single-depth union bolt used at the anti-dive unit end of the hose) and block-off the anti-dive fluid port with this plug:

HCP12991 Aftermarket brake system fluid port BLOCK-OFF PLUG, correct size hex-drive set-screw is used to replace a brake hose union bolt when not in use. Use 1 per anti-dive unit.

NOTE: speed-bleeders should NEVER be used when first re-filling a "dry" brake system----one where the lines, calipers, or master cylinder has been rebuilt or changed, for example----as the air in the system will compress, and the speed-bleeder valve will prevent fluid from flowing through the system. Always bleed dry systems using standard bleeder screws first, and only then install the speed-bleeders, and re-bleed!

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 postal Priority Mail, postal Express Mail, or private carrier Expedited levels of service for this item) and cannot (and will not----don't even ask!) be shipped outside of the continental USA. Additionally, there may be a per-package weight or quantity restriction, and thus multiple-unit orders of this product may have to be shipped in separate packages and will 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.

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.

ft4) These stainless-steel, bristle-wire DE-BURRING BRUSHES will work wonders on the upper cap bolt area on both the threaded and the non-threaded style of fork tubes. Tubes that use threaded cap bolt (all XJ650 Turbo, all XJ700 models, XJ750-X models, XJ750 Maxim and Midnight Maxim, XJ900RK, and XJ1100 models) should use the HCP10223 butterfly brush; non-threaded tubes can use either the HCP10222 spiral brush or the HCP10223 butterfly brush. Both style brushes have stems that are designed to be used in a standard power drill, and should be used at 850 rpm's or less. These brushes will make quick and meaningful work of the cleaning and polishing of this critical area on your upper fork tubes.

HCP10222 Aftermarket stainless-steel double-density spiral DE-BURRING BRUSH, for use on fork tubes without a threaded cap bolt.

Fork Tube Oil Level Gauges:

HCP1728 Fork tube oil fluid level measurement GAUGE AND SYRINGE. This handy tool makes the measurement of the fork oil level easy and accurate. NOTE: the proper amount of fork oil is determined via the measurement of the fork oil LEVEL (distance below the very top of the inner tube) rather than a volume AMOUNT of oil specification. Too little oil will make the ride mushy, while too much oil makes the ride harsh (and can blow out the oil seals!)
$ 29.95



ffl4) Aftermarket fork oil measurement GRADUATED CYLINDERS. The best way to measure the precise amount of fork oil fluid is via the use of these lab-quality measurement cylinders. Available in either transparent (clear) or translucent (cloudy) durable plastic construction, they all have easy-to-read scale numerals (milliliters) and feature a "non-wetting" inner surface coating that prevents the concave "meniscus" from forming at the top of the fluid, thus insuring a much more accurate level reading. Large bases insure stability while large spouts make "the pour" easy and prevent messy drips. Very useful device to have for front fork oil changes.
