diff oils

[dadnjesse]

What wieght oils do I need in the front rear and center diffs for a LSP truggy.

Well with a center diff it gets tricky. If the oil is to thin you'll just spin your front tires on take off, to thick and you'll be on your roof every time. Front and rear oils can be the same, maybe a little thicker with the rear to help cornering. I can't recommend any specific weights because I have no experience with MT's, center diff's, or 4WD for that matter. Hope this helped a bit.

Well, if its brushless, its gonna be alot higher in the center diff, which most nitros usually run around 5-7k. I would suggest buying a small arangement. Usually, the rear is gonna be the thinnest, and the front the thickest, but with BL, the center will probably be. A nitro usually runs around 10-7-5, 7-5-1, etc. I'd say start with 10-30-5.

i've got 50k in the center, and think it suits my power best.

I ended up using 10k up front, 50k center and 3k in the rear

how do you like it? i've still got stock in front and rear, but my rear needs rebuilding.. do you know what stock oils it had? and how does it compare now?

My CRT has 7k in the front, 30k in the center, and 3k in the rear. Works awesome for me. Although I can still pull the front tires off the ground on the straight away, so maybe I need to thin the front a little?

i run 7F/30C/5R in my Losi 8T with Neu 1515 1Y/F on 4s lipo...

The stock Lsp only has grease.

Yah need to thin the center if you're pulling the front end up.

Actually I'm going to thin everything. My steering isn't as tight as I would like it to be so that should help me there too. I'm thinking 5/10/1 as my f/c/r.

I use 7k in the front and rear and 50k in the center. I had good results with a nitro engine so we'll see if it still works fine when i get the brushless stuff in there.

I've tried to use the various "formula's" out there to predict how my truck will handle with "lighter" here or "heavier" there...in my experience, your truck and driving style are sufficiently different from that of the advice giver that you really have to see for yourself. In my E-CRT, light center oil made the truck very unresponsive. I felt like it allowed too much power to go to wheels which were slipping. The result was a strange acceleration curve and poor steering. When I thickened up to 50K in the center it made a huge difference. Much snappier performance and better, more responsive steering to boot. Not sure I can explain it but I won't go lighter in the Electric CRT. Oddly enough I went from 30K to 10K in my Nitro CRT and prefer the 10K! Same tracks, different power delivery.

Thicker oil in the CD will allow better take-off if you can keep the front on the ground. Thinner oil will help on-power steering a LOT more, but take-off will suffer since the front unloads easier. I would say 30k-50k depending on the weight distribution and how curvy the terrain is.
