Rear Axle Length and Engine/Trans Position

I have a unique problem which I need some of your help with. My Riot is a pre-production version. And I have plenty of examples of the fact that some of this was not fabricated on a fixture.

My problem is that my left side axle is fully extended about 0.5" prior to the suspension reaching full droop while the right side axle still has a good 1" of movement. I took some measurements and found that the left side distance from the transmission to the wheel mounting flange is about 1.5" longer than the right side! YIKES! Everything else measures good (suspension droop, etc).

I believe the engine/trans is not placed properly in the rear....it should probably be about 0.75" further to the left. I took a few pictures of the motor mounts on the lower rail along with a picture of the transmission position with respect to the rear mounting plate. See below. Maybe someone with a "good" Riot can post some pictures to tell me if mine is truly off or maybe I have something else going on.

BTW: The result of this was to have my left side rear axle pull out 4 times during my last trip to the dunes!!!

Thanks.

Re: Rear Axle Length and Engine/Trans Position

I got the info to have a longer axle shaft made for you. I guess we'll wait to hear from you after you get some feed back from this post.

Re: Rear Axle Length and Engine/Trans Position

I still want to go with a longer shaft on driver's side because the overall track width is symmetric so I don't want to move arms. And I am, in no way, going to cut engine and trans mounts and redo those! So my easiest option is a longer shaft on driver's side assuming cost isn't crazy expensive.

I left you a MSG. Give me a call when you get a chance.

Re: Rear Axle Length and Engine/Trans Position

Mike-If you can still get a hold of Jerrud he had a fix for the axle coming out in the pre-production/early riots, He told me my 09(#18) could have this happen but it never did and I have since forgotten what he told me that the fix was.

There was an axle length issue. Redline had received some axles from Gorilla that were not made correctly and the axle shafts would stick in the CV joints instead of moving. Gorilla corrected the problem with Redline and Redline was trading up axles with owners as the surface because they had no idea which Riots ended up with a bad axle. I know of a few owners that have had this happen too. Ronny I believe was one of the first to experience this problem on the race track and we brought to Redlines attention. With Ronny working with them them figured out that there was a problem.

Unfortunately, if this happens to a Riot owner at this point they can contact me and we can get the info to Gorilla. Gorilla can take the axle and correct it, but there will be a cost involved because they already sent corrected axles to Redline to handle the issue. I have been unable to get Redline to respond regarding helping with the axle issue at this time.

Redline was also doing something with the Riots that were built with the Fox shocks. Don't quote me on this, but I understand that shocks were allowing the suspension to droop too far and cause axle problems. Maybe someone that owns a Riot that has or had Fox shocks can chime in on this one. Everyone that I ever worked on had Elka's.

Re: Rear Axle Length and Engine/Trans Position

I opted to go with a 1" longer axle on the driver's side. All other options were going to be way harder and likely mess up something else. Thanks to mike at RRR, axle is on it's way from gorilla. I will post up how it goes.

Btw: I recently tried the gorilla method for getting the CV joint off the end of the shaft by hitting it hard with a big hammer. It broke a small portion of the outer cup on both ends! It got the off with one big hit, but slightly messed up the cups. It won't hurt the overall function of the joint, but it was unsettling at first.

Re: Rear Axle Length and Engine/Trans Position

Back from the dunes with the 1" longer shaft on the driver's side and square cross section snap rings.

During my second hard run following quads, driver's side axle pulled out AGAIN! Ugh. Getting tired of this.

Got it back to camp and did some investigating. With the shaft all the way into the trans, I was able to hand "slide hammer" the shaft back out against the force of the square snap ring. When I ran these in my Revolt it was almost impossible to get them out. This one came out slick as you please.

I did some measurements and the snap ring is in deep enough to be past the end of the internal splines. I took the snap ring and spred it a bit more before re-installing. And it seemed a bit tougher to get it to come out....but I could still get it out after a few pulls by hand.

I ran the rest of the weekend without running as hard as the first two runs and not more issues all weekend. I still hit jumps and duned and ran hills. But I wasn't cutting and cranking as hard as when I was following my quad buddies. Before the longer shaft it would pull out without hardly doing anything. So it seems to be improved, but not fixed completely. I need to figure this out so I can quit worring about it.

One thought I had was that perhaps if under full droop I make a left hand hard turn, the body roll adds more extesion to the shaft and it pulls just enough to disengage the snap ring. And then the on/off torque just helps walk it out. I am going to take some measurements and flex it around this week to see if I can duplicate this situation.....if so......maybe I need a slightly longer shaft on both sides??!! We'll see.

I just LOVE working the bugs out of a buggy Riot! Remember....this was a preproduction rig.

Re: Rear Axle Length and Engine/Trans Position

My two cents on this one. Same problem with my pre-production Riot, but the passenger side axle kept coming out. What I found is the groove in the CV joint for the snap ring is too deep allowing the c-clip to easily compress and the axle to slide out without much effort. I wrapped a small amount of safety wire in the c-clip groove, then put the c-clip on top of the safety wire in the groove and installed the axle. It never came out again.

Re: Rear Axle Length and Engine/Trans Position

Run the axles without the inner axle shaft snap ring. Lock the axle in with good square topped clips on the outside and don't put any clips on the actual axle!. Two benefits, you can fast change the axle and it won't ever pull out again! Every race I ever entered had my axles done like this!!

Seriously?!?!?! That worked for you? It seems that would allow the inner axle to always slide outboard and keep the spline engagement at the trans as minimal. I'm not doubting it didn't work for you.....but it seems counter intuitive. I'll check it out! If I go that way, I will post up my results.

Thanks!
