3-d stearing

[kleiner]

My kids 3-d steering seems to have been damaged , it is very hard to turn, re-moved cable from water jet nozzle and that moves just fine ,

My '04 3D had tight steering. Took to dealer when under warrenty and they replaced the bushings at the column. This worked for about a year. I took the column apart and cleaned the bushings and steer shaft, both had gummed up lubricant. Relubed with Bel-Ray waterproof grease. This worked for the next 3 seasons till I sold the boat. Also check the tightness of the steer shaft bolt, the one with the folded lock washer.

I bought two 3Ds a couple of months ago, one has very tight steering as you say. I took apart the steering mechanism per the shop manual and found the pillow block and bushings to be culprit. Lubricant did not make a difference.

The inside of the pillow block that contacts the bushings has some dings, so I am replacing both (about $92 for all the parts). I'll let you know how it goes.

I did the pillow block + bushing replacement on the 2004 3D, got everything back together and the steering is now silky smooth. Very nice.

Total parts were about $100 ($25 if you just want to replace the bushings). Very much worth the effort. Total time was about 4 hours, though I could probably do it in half that time now.

Pillow block + bushing assembly (comes together) part number is 277001396. The bushings alone are 293900062 (you need two of them).

My steering was fine when I purchased my 3d but every ride it would get stiffer. I decided to tackle the problem a few weeks ago. After taking apart the handle pole I found the problem to be the steering bushings. They were tight enough that I had to beat out the steering stem with a punch and hammer. Nothing was wrong with them so I honed them out a bit with a small brake hone. They are nylon bushings so I expected that it wouldn't take much but honestly I took about a sixteenth of an inch of those suckers. Now the steering is nice and smooth. Didn't take too long and didn't cost me a penny. I took some pictures because I knew others had the steering problem.

my 04 3d does this as well - howver it seems to do it more after not being used, and having a cover or been hot in the sun. once you get it going, it loosens up and doesnt seem to be a problem. now i suspect its likely those "nylon bushings" that you are talking about. have to rip er apart when i get it out of storage again.
thansk for the posts, and the pic.

the hone trick works nice, done it once
what i have seen is corrosion starting between bushing and coloum
the corrosion gets between the two parts and puts pressure on bushings
when i replace the bushings i also make sure to clean the coloum good, and put some water proof grease in coloum to help prevent this

Mine did not have any corrosion on it and it was very well greased when I took it apart. The only thing I could think was the the heat down here in Louisiana caused the bushings to expand, and being very tight tolerances, just squeezed the column. Taking a few thousands of an inch off the bushings worked wonders.

3D needle steering has not been demonstrated in the presence of tissue deformation and uncertainty, despite the application of progressively more sophisticated planning algorithms. This paper presents a feedback controller that steers a needle along 3D helical paths, and varies the helix radius to correct for perturbations.

had the same problem with mine

My kids 3-d steering seems to have been damaged , it is very hard to turn, re-moved cable from water jet nozzle and that moves just fine ,

I had the same problem with mine the grease contained in the neck where the handle bars are mounted between the two rubber bushings is dried up you can either spend $120 in replacement parts from your dealer or you can do like i did and drill into the neck just past the bushings,tap the hole for a grease fitting, place a grease fitting in tapped hole and pump new grease into the neck and work the handle bars back and forth til they free up. hope this helps i did this three weeks ago to mine and its still steers like its brand new

3d Steering Probs

I had the same issue with one of my 3d's steering. It was semi-easy to turn when it was cold but once hot, it became extremely difficult to turn... I took it all apart expecting rust & no grease, but actually after really working to get the rod out I found it to be just fine(just extremely tight) I went to Lowes bought a small round 1" grinder bit ($3) I put it on my cordless drill and spent ten minutes shaving down the sides about 1/16th of an inch. (You might need an extension for the "bit" to grind all the way down to the bottom) I then added grease & replaced everything... Worked Perfect, Extremely smooth and easy to turn. Took it out on the lake yesterday what a difference!

uhhhh...wtf

...are you high?

 

[kevinjansen]

i think your train of thought here has surpased the home-owner do it yourself repair guys! That or maybe this is on the wrong post????
maybe just me but no clue what your talking about! (oh this is in regards to the 3d needle post above. i think someone else thought they were high too!!!)
