Gear diff maintenance and rebuilding

Hello everyone,

This week I would like to cover the next question that came up on my recent post on the #22empire and that’s 1/10th scale gear diff maintenance and rebuilding. In the picture below, I’m rebuilding my gear diff and I’ll give a description for some key items when rebuilding a gear diff. A) Disassemble and clean all parts thoroughly with motor spray (do not clean o-rings with motor spray). B & C) Show all parts after cleaning. D) Reapply new high-pressure black grease and the O-rings followed by the flat washer on both sides of the diff. E) Reapply threadlock to the outdrive setscrew. F) Refill your gear diff with your diff fluid of choice. G) Tighten the four outer case screws in a cross pattern. This will give you a nice new freshly rebuilt gear diff ready for racing.

Diff maintenance and rebuilding

Hello everyone,

This week I would like to cover the next question that came up on my recent post on the #22empire and that’s 1/10th scale diff maintenance and rebuilding. In the picture below I’m rebuilding my diff for this weekend’s Hot Rod Shootout race at Hot Rod Hobbies and I’ll give a description for some key items when rebuilding a diff. This diff has about three large race events and some club racing events on it and you can feel it’s a little gritty. Picture A1 and A2 shows “flipping” the drive rings and trust washer for a new surface area; this is key because not doing this will result in having the same gritty feel you're trying to get rid of in the first place. Picture B shows cleaning of the internal parts of the diff (I.E. outdrives, rings, trust and diff balls). Picture C shows reassembly of the diff with new silicone grease. Picture D shows reassembly of the trust washer assembly with new high-pressure black grease. This will give you a fresh new diff ready for racing.

LRC vs. HCR

Hello everyone,

Recently I asked the #22empire for some feedback on what they would like to see covered here on the Team Losi Racing blog. I received multiple questions and I will cover them all in the next couple of weeks. Out of those questions, a majority would like some input on LRC vs. HCR and which conditions work best for each. LRC lowers the inner hinge pin which equals more roll for added grip and a softer suspension feel on the track. HRC raises the inner hinge pin which equals to less roll for less grip and a stiffer suspension feel on the track. Overall I wish this was a cut and dry question but it’s really a decision setting for which track you’re on and how you like the feel. I’ve raced on tracks where HRC should be the best and felt better racing with LRC. Here are some key points I associate when I need to decide on LRC or HRC.
LRC = if the track is lower grip/bumpy
HRC = if the track is super high grip/smooth (like a condition when front and rear sway bars are needed)
