I have a Losi EP Truggy as well but have only experienced funky clunky noise on my buggy. Turned out to be a bearing on the outdrive of the rear diff--one of those flanged bearings. The bearing essentially came apart and the noise, I can only assume, was from the gears. Have you taken apart the front diff case and checked over everything?

I have been running a 15 tooth with a 45 and I melted a few sper's. so I purchased a robinson 47 steel. in order to have the same gearing what pinion gear would be the same as far as the same gearing 17?

Chucko I have always been told to go 1 on the pinion for every 2 on the spur. I have been told this by on-road guys (much finer pitch) but seems to be right. If I were challenged with the same problem I would use a 16t.

No I haven't taken anything apart but I guess it can't hurt to do so.

It certainly would not! The Truggy takes a lot of abuse and needs a lot of maintenance . . .

Tekno kit help.
Didn't even realize that my NEU2200 can was only 40mm. The tekno V4 kit comes with the 42mm mount.
Stupid question of the day is, the 40mm V3 motor mount still bolts to the V4 chassis correct?

Got a good chunk done tonight


Cant decide if i want to keep the blue towers or not. they look terrible against the tekno chassis but they match my body... I do have a set of TLR carbons on the way.



And i need to decide if i want to put the RX box on the other location or not.

in no way trying to be rude, its simple math so 15/45 means that for every turn of the pinion the spur turns .333 turns so

15/45 = .333
15/47 = .319
16/47 = .340
16/48 = .333

that being said latley I've tried to run larger spurs with larger pinions as there is a greater tooth contact area and less chance to strip them or break

had very similiar isse with 2 different truggies, one was rear diff other was front.

I can only assume the extra weight has a harsher affect on the drive train as our 8e buggy has had no issues in this area

Can anyone confirm what center differential mount i need to work on the Tekno kit?

On the notes it says if you are converting the E use the nitro 4415 kit, but the 4420 is the E mount? Visually they look identical. Is there actually a difference?

I have a 4420 waiting at the LHS for me, just need to know if I'm gonna have to change that.

Could be, can you set it up on your stand and give it throttle and replicate? Do you know the sound the rear diff makes as it starts slipping and stripping? If it's the rear diff shim it quick and you maybe able to save it, if it's a bent shaft, best thing is to just replace it. Bent shafts do happen especially if you don't run a traktion drive or slipperential to help protect the drive line in a truggy. If it ends up being the rear diff, make sure you replace the ring and pinion gears in the diff.. mixing old and new never works well.

+1 avid and change more often and you will net better performance for less money and way less work. Think about it for the price of even lower end ceramics your at like $5each, you can spends the same amount with avid and have 5 full sets for the same price as 1 set.

The E-kit top works with the tekno, but the rear center diff is the motor mount so you cannot use this unless you have both the plastic front and rear center diff braces. The nitro kit will get you the correct parts needed, but as I said you can get the top plate off the e-kit if you wanted it but it is not needed.

BTW Losa4420 is the 8ight 2.0 nitro part (updated parts) - this is fine and will work great and is better than the older 4415 kit as it doesn't need the extra bearing spacer.
