Weird Fork Oil Change Accident

Post by mytown »



Was using my handy tool to remove the fork caps:


The right one came off no problem. But this happened the moment the left one came loose:




The bike was on the center stand, but I imagine after removing the air and oil from the forks they had collapsed enough so as to put weight on the front tire. Once the spring tension released It quickly dropped and then slowly rolled forward. I was able to grab the handlebars before the bike fell over and prop it up with a nearby workbench. The front brake hose union is now pressing down onto front fender.

there is nothing weird about it. that is what will happen if the bike is not properly supported to take the weight off of the front wheel. when working on the front end i use a jack under the front of the engine (with a wood block of course) to lift the wheel off of the ground. i also use a tie down strap from the bottom of the center stand to the front engine guard to keep the center stand from folding back. sorry this had to happen to you. i hope the rest of the project went well.

+1 the bike has to be jack up off the ground..front wheel at least. While on the center stand if you have someone sit on the bike that will do it or some cement blocks but the correct way is with a bike jack under the engine.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

I will not. It took a while to find the cap. It obviously had flown past or over my head. Could have taken out an eye or worse, my dentures.

Just to be clear, this will happen to all bikes, not just the wing, if there is any weight on the front wheel when you unscrew the fork caps, the front end will collapse as the cap unscrews from the fork. You must always find a way to take all weight of the front wheel before you loosen the fork clamps, unscrew the fork caps or generally do any work on the forks or steering head.. Glad you weren't hurt, and as stated, you won't do that again!! Hope the rest of the maintenance goes as planned.

I did that my first time changing fork oil on my CB750. Took the cap blow right in the middle of my chest. I'll never do that again!

One side at a time from now on!

Got the bike jacked up and filled the forks. I'll be doing it again since I discovered that one of the seals is leaking. Normally I would replace the seal now but I need the bike soon because of the traffic issues likely to occur as the result of the eclipse. I live in a college town and Monday is the first day of class of all things.
I struggled with replacing the fork caps until I finally removed the 4 allen bolts securing the handlebars and moved them out of the way. It them became an easy matter to replace the caps by hand:


Now that's what I call room!
Not positive, but it occurred to me that the starting point for the screwing in the caps may be the same place that they end up, that there is a certain number of complete turns. This would explain how it is that the fork caps are interchangeable as I have seen.
I had to really crank on the right fork to get it into position to connect the air hose. I never did get a perfectly straight line.


Next time I'll have on hand new o-rings for the caps and the air hose and put a new core into the schrader valve.

Crank on the fork to get in position? Did you loosen the pinch bolts and turn the tube to align? I WOULD NOT ride the bike with that type of angle on the fitting if it were mine. Worst case scenario total air loss at speed resulting in possible speed wobble/tank slapper then OUCH!!!!!

I meant to say crank the right fork CAP. Good catch. It was a tight squeeze getting the fitting past the handlebar stanchion but once past it went in straight. Never thought to turn the fork tube and frankly did no know I could do so! :oops: Thanks for the information, that's very good to know.
