I need some help with the clutch and shifting on my CEN MT2. I recently had to replace my spur gears. Before replacing the gears, my 2nd gear was shifting fine. Since the replacement of the gears and re-assembly, the CEN runs fine, just will not shift into second gear. I followed my manual for the NT-16 engine, says to close the clutch screw all the way in, then back it out 1 complete turn. Still, no shifting. Its like is running as a single speed CEN. I might have forgotten a washer/spacer or something? Anyone have some suggestions on what it might be. I double checked the clutch shoes and they are installed in the correct direction. Currently using the same racing clutch with the all around spring. Had it installed before the spur gears were replaced, using the same clutch setup now. So im guess that is not the problem. Hey, thanks to all suggestions. CougarTech. [8D]

Hey man, have you tried winding the screw out more? Keep going say 1/4 turn at a time and see if that helps. If no luck strip it down again and start over.
Good luck dude.

Did you put back the three items that are in inside of the two gears. Also does you gears both turn at the sametime and are able to turn on the own.

Thanks for the reply back. I currently have it apart again. I read in a few of the other CEN forums, that its possible for the 11t/14t clutch housing to get "glazed" or "worn out". Is simply cleaning it the solution or can the 2speed clutch housing actually get worn out. I know the gears can get stripped, but, my gears look fine. How can you tell if your clutch shoes are worn out. Is it that raised area on each shoe? How many turns from closed, would anyone suggest on the clutch adjustment for the MT2.? I followed the manual, all the way closed and 1 complete turn out. I have tried adjusting the clutch more, still, no engagement into second gear. I do notice that my 11t/14t clutch housing gears do not line up exactly with the spur gears. They are about 1 or 2mm short, or off, from lining up perfect with the spur gears. This is why I was wondering if I was missing a washer/spacer, or some other kind of adjustment part. Any other suggestion out there.. Thanks in advance to all... [&:]

Are those 3 parts washers/spacers? I had bought this MT2 a year ago from someon else on Ebay. It has never given me troubles. Just recently needed a replacement of the spur gears. Im sure that Its something that Im missing. Must be a missing part, cause my 11t/14t gears do not line up perfectly with the spur gears. They are supposed to line up flush with the spur gears, im sure. I will double check my manual, and take apart my clutch again. Gotta find out what I missed. I also have a few HPI MT's., and I have been working on more than one MT at the same time, so probably I moved some pieces from my CEN over to the HPI table and that's why Im having troubles. Okay, back to the manual. Thanks for the suggestion.

cougartech... If your engine is running correctly and winding out enough it will shift.. if not, it won't.. simple as that... make sure you back off the adjustment screw a little more 1/4 turn at a time after the engine is leaned out... I occasionally cannot get shifting to 2nd until I make sure the engine is running correctly... The mesh being a little off won't make a differnce as long as its not rubbing the spur gears... you may strip a gear but thats about it.. Just tinker with it a bit, once you get it, should be set for a long time... Unless you somehow have hpi parts mixed in

Also make sure that the 2 speed unit is installed the right way. I know it sounds obvious but sometimes it's the simplest things that screw things up.

Thanks again CenRacer1 and Rolland. I plan to take the 2speed apart and rebuilt again. To make sure I have it setup correctly. Hey, its good practice anyhow. I have a few MT2's so I should get used to doing this kind of repair anyhow. Thanks again for the suggestions. I will let you know how it turns out.

Are you sure it's not shifting? I just put an OS motor in my MT2 and it shifts in the first 10 feet and it happens so fast that you really have to listen to hear it shift.

Rolland...Mine did the same thing when I first changed the motor to the o.s. ... I tightened the shift point to wait a bit.. the truck is much faster now because the engine is allowed to wind out a bit more... also, allowed for more wheelies, something it never did with the old motor...

Thanks CenRacer1 and Rolland. My MT2 with the OS .18 works great. This is regarding my MT2 with the factory NT-16. My MT2 with my Epic .18 is doing the same thing. I worked on both of these MT2's, not the OS .18, recently, so Im sure its something that I did wrong during re-assembly. Any other suggestions? Is the turning out of the set screw that critical? whats the max number of turns out?

I also have the same problem with mine, but mine wouldnt even shift the day I broke it in, the only way it would shift is if I leaned it way out and the temp was running around 290 degrees. I know it wasnt shifting too, because when it would shift that thing would scream. Also, I know this is off topic, but I was thinking about getting the JT chassis kit, and I was wondering if it came with everything it says it does.

The JT chassis kit includes the main chassis plate, front and rear shock towers and front and rear braces. Its well worth getting as it strengthens the truck immensely.
As for the gear change, mine was screwed way too far to the right (late change) when it was new. I had to screw it all the way left then all the way right to find out how many turns would be central. If you are unsure whether your truck is changing or not, it isn't. The engine change is definitely noticable and if you hold your truck in the air whilst revving it, there is a definite kick when second gear engages.

I am going to switch to a 13/16 bell and see how that runs before I try to adjust it. As it stands now the stock 11/14 is to low geared for the truck with the stock tires. I am not all that interested in wheelies or low end torque I have an X-Factor for that.

Hey Guys. Trying to get back on topic. I might have figured out what I did wrong, in regards, to my MT2 not engaging the 2nd gear. There is a part, of the transmission, not sure the exact name of the part, but this is where you have the 2 screw locks. One is screwed all the way in to hold the spur gears in place. The other screw is sitting on a spring, then on a little metal ball. This is for adjusting the 2nd speed gear engagement, right? Well, I had left both screws in tight. So I re-adjusted the screw with the spring and ball, i backed it out 1.5 turns out. Will run the MT2 tonight to see if it worked. any other suggestions?? or theory's? Thanks Guys. [8D]

don't take this the wrong way, but I thought you understood how the trans worked... I said in a past reply to make sure you back off the set screw.... Anyway, that will fix the problem.. now for mine.. Did You put a voodoo curse on mine.. It wouldn't shift yestersay out of first.. The engine was screaming to the point of non stop wheelies but wouldn't shift.. I didn't have an allen wrench on me to adjust it.. just a little 1/4 turn should do the trick...

Thanks. I do understand how the trans works. As I have mentioned before, it does sometimes take me a few extra times to grasp the whole concept. Once I totally understand it, I have it completely in mind. I might have made a mistake, when I said that I had backed off the clutch adjustment screw, cause I have been working on my HPI MT and CEN MT at the same time. Probably a mistake. I think it was the HPI MT that I was referring to. I figured out what I was doing wrong with the HPI MT, I had the clutch springs on backwards and the screw did need a little more adjustment as well. With the CEN MT, I did not realize that when I re-assembled it, I forgot to back out the screw a turn or two. No worries about taking this the wrong way. I still have lots to learn, but, having fun along the way. Thanks again for the info and suggestions. I was mainly confused about the 2 screw holes, which one was which. The set screw holds the "*&*JL" in place, wasnt sure what its exactly called, and the adjustment screw allows that clutch plate to push up, allowing the vehicle to shift to second gear.... So glad the weekend is coming up, hoping for some clear weather so I can play with my MT's... [8D]. Sorry about the VooDoo, CenRacer...
