Kartboy Shortshifter Buzzing
 

I got a Kartboy shortshifter and installed it and in every gear I get pretty severe buzzing (that I can hear). Anyone know what's going on? The only thing I "fucked up" on is that I ripped the "dust cover" under the shifter, which I'm not sure if is a serious issue or not - but I doubt that is causing the buzzing. Any ideas? It seems I installed everything pretty smooth.

Maybe something isn't tightened all the way/to spec? I'm not familiar with the shifter install, but it sounds like a loose nut or something that's vibrating enough for you to hear the "buzz".

As stated above, recheck everything. If not, you can always just sell it to me.

I rechecked twice so far. First tweaks helped but I still have the issue.

Kartboy Shortshifter Buzzing
 

(this was moved to "cosmetics" for some reason so I'm reposting it).

This will get moved as well. The buzz is the dust cover acting like a balloon when you let the air out.

At least it got moved to the proper spot this time. You really think that's it? What's the part called if anyone knows and where can I find it? It doesn't quite sound like what I'd imagine a "balloon" sound to sound like - it's more of a rattle like metal but there's nothing loose, I cranked everything. The sound occurs at any RPM and just gets more intense.

I'm talking this rubber part: http://farm9.staticflickr.com/8235/8...2b5d4f3b_c.jpg

Will order and try that out. Easy fix would be nice.

If you are talking about a metal vibrating noise when revving, this is normal with some of our transmissions.

I had the same thing. I have literally tried everything you can think of to get rid of it.

Only fix I found was I got a 1.5 pound shift knob and know it only slightly rattles at around 6-7k rpms.

Well it's only since I put the short shifter on. It rattles just driving down the road normally. I did just buy a 1lb shift knob... The buzzing goes away if I grab down below the shifter and kind of pull up on the rubber underneath the sleeve thing which I guess is worth mentioning... almost wanna put on the stock shifter and see if it still rattles (confirming it's the dust boot).

I had the same thing only after I installed my kartboy. I reinstalled the OEM one to see if it was just the shifter and the OEM shifter also had the same problem now. I don't know if its something I did or just an odd circumstance. I had researched this problem very in depth and iirc it is a known issue which Toyota issued a TSB for. Of course you would have to reinstall your OEM shifter for them to do anything.

I don't know what the rubber underneath the sleeve thing is so I can't help you there. Maybe if you were more specific or showed a picture.

Only tips I can give is make sure you still have the small washer between the cotter pin and the shifter linkage. Make sure the shifter is properly torqued and not over torqued.

Mine sounded like this

In that video they reference this post which I never came across but funny enough I actually did the same thing.

Final Edit: Found the link to the TSB in regards to shifter rattle.

I probably over torqued it a bit though don't think that's it - I muscled it as hard as I could. What a bummer you have it even with the stock shifter now.. that's weird. I did get the washer back in which I'm glad for since I dropped it and couldn't find it forever.

Mine sounds more or less the same. My 36 month expires like tomorrow or something =[ Make that 3 days ago actually.

Try the larger washer trick. That pretty much eliminated the problem for me.

Larger washer trick? Can you please explain. I'm guessing it's something like "use a larger washer".

Check the first link in my above post.

Great thanks. I'm optimistic that will help. Also bought the dust boot.

Alright well I added a washer that was about 2x the thickness and still the same issue; no difference.

What's interesting is if I'm going 6000 rpm or whatever (super rattle) and pull up on the "lever" or whatever it's called (to go into reverse) it goes away. This is at any RPM. If I pull the knob up it stops rattling... any ideas?

Still waiting for the dust cover to come in, but the bigger washer didn't help.

HELP!!!!

Is this a new kartboy or used one you bought off someone?

Brand new. I've opened it up and "reinstalled it" 6 times now or so. Only thing I can think of is the washer isn't big enough (new one is about 2x the size) or it's the dust cover)... or it's a faulty unit, or something else that I can't think of.

Well another thing that I tried was I took the reverse lockout plastic piece off and got some grease and smothered the metal rod with grease.

Take your shift knob off and drive, if it still rattles take the reverse lockout off and take it for a drive. See if it's one of those 2 things.

You're talking about the bottom black Kartboy piece and then the silver metal piece yeah [I'm new to most of this]? The most confounding thing to me is when I pull up the level the noise goes away. My reverse lockout part is metal I believe so your post confused me a bit. I've got as much grease as I can on the actual rod so far hah. I appreciate your input/help.

I'm talking about the black piece you actually lift to put into reverse. Take that off and drive, see if it still rattles.

Oh I see. Not sure how to get that off.

I've tried every other damn thing. Even drove with it all off basically and yeah still rattlin'. Kinda wanna throw the stock shifter on to see if it still happens to identify if it is in fact the new Kartboy or the dust cover that's missing. At this point I think there's something wrong with the unit as I've put 10+ hours into troubleshooting this thing.

Did you put the little rubber washers on that Kartboy supplies with these now?

I recently installed one and have a similar rattle in all even-numbered gears and assumed it was rattling against the reverse lockout plate. I had a rattle from the Kartboy SS on my bugeye and the "fix" was to dremel out a larger hole. It hasn't been loud enough to really bother me (especially when competing against intake, exhaust, and music).

You're not going to be able to remove the plastic reverse lockout piece on the Kartboy--this is part of the shifter.

I did not and wasn't sure what those were for.. I lost them, but I just remember they were small o-rings or were they rubber washers the size of the stock black one?. Do they go against the washer/pin? Yeah I didn't think you could take that off. Mine bothers the hell out of me unless I'm blasting death metal. Mine's in all gears. It's not really noticeable under 3000 rpm but it's definitely there. I have really good hearing =[

What is weird to me is when I pull up the lever the noise goes away. I'm positive I've installed everything correctly, besides ripping off the dust cover =/. I also bent the little "dust cover" that goes on the bottom of the shifter (from the stock one, probably from messing around with the whole assembly so much), which I can't for the life of me find a part # for but doubt it'd cause a metal rattle sound.

I'm on the stock shifter and get inklings of rattle at 3.5k, it really starts to buzz at 5k+. I plan to replace the nylon bushings and rubber o-ring, possibly doubling the o-ring, and then greasing everything thoroughly.

I put in a steel washer that was twice as thick; might try adding an o-ring next. I added a 1lb shift knob to it and it actually helped quite a bit.

Where do these little rubber washers go that you speak of?

You actually can remove the plastic reverse lockout piece. There is a small pin near the top that you can tap out and then it just slides off. I did this and added some extra grease in there.

Yeah I'm curious too. And that's interesting I'll give that a try... the 450g shift knob made a HUGE difference.

They go on the control shaft linkage. I'm guessing you both used the DIY on this forum for the install--they weren't included with the shifter originally, but if you jump to the last few pages of that thread, others talk about them.

Are they just o-rings or rubber washers? Did you fit both on or just one? And did that clear up the rattle? Thanks. Yeah I used that DIY.

(i lost them)

I didn't put them on, but it sounds like your rattle is worse than mine. Based on comments in the DIY thread, it seems like most people could only fit one but it did help with the rattle.
