    Thumbs up Swing-Arm Bolt Stuck? Honda's Prevention Tip!

    How many of you have heard the Horror Stories about Frozen Swing-Arm Pivot Bolts freezing up, preventing removal of the engine, Swing-arm and the resulting carnage that follows?

    Why do the bolts get frozen, and how do you prevent it from happening to you?

    Well, the obvious answer is to keep the area maintained properly, keep it greased, and free of dirt and water. Sounds really simple and it is if you are into removing the bolt all the time. There has to be a better way right........read on!

    The reason the bolt gets frozen in the first place is from a lack of lubrication. The swing-arm pivot is one of the most important areas on the Quad, it is after all the main pivot point for the rear suspension, the load on this bolt is very high, and it is constantly moving. Add a little water, some dirt, maybe some sand into the mix, and well we all know the end result, bust out the cutting torch, hack saws and any other cutting device you find fit, after of course you have already tried pounding it out with a sledge hammer, probably bending the frame in the process.

    When not properly maintained, the bolt and metal collars that it slides through will begin to rust. The metal collars and the bolt fuse together, and that is why it cannot be removed.

    I have a solution, and it is much cheaper than the $60.00 stainless bolt that some shops are selling.


    Go down to your local hardware store and pick up the following:

    1/8" NPT Standard Grease Fitting (Zerk Fitting)

    5/16" 24 Allen Cap Screw (Set Screw)

    5/64" Drill Bit

    You will also need access to a drill press, tap and die set and have a grease gun.


    Take the Stock pivot bolt, drill and tap both ends. You will tap the threaded end for the cap Screw and the other end for the Zerk/ Grease fitting.

    After you have the ends tapped, you will need to drill 6 holes through the bolt using the 5/64" bit.

    Starting from the unthreaded side of the bolt, starting under the flange on the head of the bolt, measure 3/4" and drill one hole all the way through the bolt, do another at 3", another at 7" and the last at 9 1/4".

    Rotate the bolt 90 degrees, and then drill two more holes through the bolt, one at 1 7/8" and another at 8 1/8".

    After you have drilled all the holes, de burr all the holes, then clean the inside of the bolt to remove all the metal shavings.

    Now coat the threads of the cap screw and Zerk fitting with a good sealant, such as RTV or what I prefer, Honda Bond which is available from your local Honda Dealer.

    Thread the cap screw, and Grease fitting into the end of the bolt and tighten.

    Reinstall the modified bolt onto your ATV and using a grease gun, fill the bolt with grease.

    Now you have no excuses not to keep that bolt lubed up. Lubing the bolt is as easy as grabbing the grease gun, and pumping her full of lube! This method will also prevent any water or foriegn debri from getting access to the pivot area, because it allows you to fill the entire void with grease.

    I've done it too but I've found that grease likes to take the path of least resistence therefore the first set of holes the grease comes to get greased well but the ones at the opposite end don't get nearly as much. So what I did was grease one end then swap the fitting and the plug from either end and grease again.
