I've got about 15 gallons on my 8B and have only changed one diff.

Just for Integra

These pics are of 2 diffs that I have pulled from last race. 30min runtime MAX. I have pulled 2 more today, which were also 30min runtime MAX. The tracks these were run on is a small track (40ft x 80ft) and semi-high traction, no loam. No shims were used IN the diffs.







Diff #2

Wow i ran my 8ight for 6 gallons and never replaced the diff cases and only changed the fluid 3 times in 9 months. The last fluid change was right before i sold it and the cases weren't worn at all. But i heard Losi changed the plastis in the cases to save a few pennies. I'm glad i don't have one anymore. The handling isn't worth the headache.

There is no pleasing the almighty Integra At this particular track (Camarillo Roadrunners in CA) there are 2 5min heats and 1 10min Main. It is primarily an electric track. There is about 2 minutes between heats for practice. I used less than a tank for a practice before the races, then proceeded to clean the vehicle and double check settings for the quals. Before pre-grid on the quals, I would run 2-4 laps to get my engine up to temp and check on track tune. So ya, 30min max. Lap times avg 14-15 seconds. I would pre-heat the engine on my pit table. Not a strenuous day by any means for the vehicle. The diffs just do not hold up for me. All my diffs have been bought from tiltedrc or carolinasrc.

Sometimes the best thing to do is to move on to something new

Really, I do love my 8ight. I have had it for a little over a year, and am ready to have fun with a different chassis, hence my 808 purchase. Plus, no diff upgrade needed, or even optional.

Rez,Maybe your diffing out to much . I know you personally and I know your skills on building and set up , . However are you filling the diffs with enough fluid or to thin of fluid? Just thought I would ask

Hi Rezenclowd.

A silly question if I may: does any one else at your track run the 8ight, and if so, are they experiencing the same diff problems?

My car was from the initial run and I still have the same diff cases. Granted, I only put about 2.2 gallons of fuel through it, but other than some slop in the steering, I've experienced none of the other problems that allegedly plague this chassis.

Changing cars may or may not help, depending on what the underlying cause of the accelerated wear is.

I fill them slightly over the top of the gears, as I want as little air as possible. This pushes just a touch of diff fluid out as I screw it together. As far as diff fluids go, nothing out of the ordinary, 5k 7k 2k I found is good at both SBRCCA and Camarillo, and the short Ackerman plate at Camarillo. Shocks I change depending on what the word on the street is regarding current track maintenance.

Not a silly question at all. 2-3 other guys run the 8 also, they do not have the problem as severe as I do. However, I do get MUCH more track time than them usually... They usually look to me for setup and maintenance.... so I am confused about why mine wear to this extent. I have looked at theirs, and asked them, and we build ours the same. (Just in case they were asking about maintenance to NOT do what I was doing...lol)

This also can happen from excessive braking too.
