Losi T 2.0 Truggy rear diff
Hi,
I have run my truggy for about 3 meetings now and all of a sudden i have a clunking sound from the rear of the car, still has the power before i heard it go past me.
I have pulled the rear differential out and the pinion gear 10T was slightly chewed apart. I have replaced it with a new one but it seems that my diff has moved slightly to the right (looking at the front to the back of the car) there for it isnt catching the differential T like it should and keeps making a clicking sound when i rotate the diff, if i manually push the diff across to the left slightly i get no clicking sound and smoother movement in the gear rotation!
Is there any way i could fix this problem?

It may not be completly nessasary to replace the case every time but yes you need to replace both the ring and pinion together. When you reasseble, shim it like the manual says.
When you put the 2 cases back together, install all 4 bolts and check for fitment. Dont put any grease on it yet.
It should spin easily but not sloppy. if its to loose, take a shim from the pinion side or add one to the left side.
You have to check with everything bolted together minus it being on the chassis. The case will distort a little when everything is together and it will give you the best reading.
there should be one spot where it spins just a touch tighter than everywhere else. That is normal.
Once you get it where you want it, pull the back case off, apply tour grease and reinstall it. After 20 minutes of running you need to check it again to make sure it still fits like it should. you may need to addjust your shims again.
I have been running the same ring and pinion in my truck for 2 years. This method works. For me atleast.

yes replace the pinon and ring gear at the same time ,I dont think you have to replace the housing everytime ,most folks like to shim the R/P tight so it feels notchy ,but IMO when you do this #1 you wear the R/P out faster cuz theres no room for grease and no room for heat to expand , as heat will grow and expand metal ,there for I like to shim with a little back lash ,and use mobile one grease ,I have had the same R/P in my buggy ,truggy for at least 3 yrs with no problems ,Having 25yrs in the gear bus this is what I do , also dont over tighten the gear box screws as this could warp the housing , good luck !!

i had it simmed by the book it was way to tight i took one out on the right side. it just has a high spot and its not bad.

Just a note the losi diff shims have two different sizes.
I use a micrometer to distinguish between the two.
I end up running just like the manual says.
