T Motion install write up 2
Hello, As I`ll explain a few things that had to do with putting the Tmo kit in the rails.
The front arm assembly goes right in new upper outer bushing needed and all the needed parts are listed in the previouse post. these bushing are the same for the outer part of the rear arm so 4 are required, the cross shafts that go thru the top part of the arms between the bushing are reused from the Rev skid. and the lower cross shaft is built in to the front arm cause the bottom part of the arm it acually seperated there is a thin cut or gap in this area where the front arm cam twist or flex not sure how much but doesn`t seem like it would be much either major part of the movement is in the rear scissor assem. The kit comes with a bunch of replacement hardware like all the poly nuts pretty much every where one has to be removed is supplied in the kit and is replaced, Like exlpained before comes with new front limiter strap steel cross shaft I installed the rev aluminum one along with the rev aluminum lower shock shaft assembly and all bolts , washers and spacer to replace the steel center shock shaft supplied for weight purposes. mounting of the lower arm and position of the washers are in the instrucktions. The parts purchased in the previous post are not supplied in the kit since its intended to reuse these part from an xp skid as an upgrade kit. Rev shocks all interchanged, lower rear scisssor thru bolt, washers and inner spacer sleeve is reused from the rev, I purchased a new upper rear shock bushing since it is the only one reused on the rear shock the shock lower part of the shock moutn to a rocker mechanism conected to the lower front arms assembly, and had a sleeve spacer to slide in the shock eyelet and shock eye fits in a slot of the rocker mechanism and the axle rods that have to be purchased seperately are slid thru the mechanism inside the shock sleeve and the new bolt to be purchased it slid thru the LH strut rod thru the axle bar and thru the RH axle rod and a new nut installed. these strut rods to up to the front upper part of the rear scissor assem where the other needs to be purchases axle rod goes there and the 2nd new bolt that again goes thru the same lh strut rod axle bar ane rh axle rod and new nut installed then the upper shock is bolted to the top part of the rear scissor with the previous bushing and shock bolt and new nut supplied.
The spring are reused from the rev along with the plastic spring mount, bolt and inner washer in the rails and new supplied nut and goes back in the same spot as the xp , and the alumimum collers with the set screw in them (don`t tighten the set screws till skid is mounted in sled cause if you tighten the set screws a bit to tight is squeezes the upper tube and the bushing won`t slide in) that go outside the upper wheels are also reused from the rev, the upper wheels are supplied in the kit New outer upper bushings are needed and the rear upper cross shaft is reused from the rev.
The rear inner 2whl axle assembly is pretty cool, rather than just relying on the aluminum spacer between the wheels from bearing to bearing the XM has about a 2inch inside diameter black plastic tube that goes over a lip inside of the wheels from wheel to wheel and give the setup more strength and the wheels are not as likely to bend or break over, I like the Idea. I was going to use the xp yellow outer wheels I had pic of previously but I got a tip or 2 that the bearings are not centered cemetricly in the wheels and make the wheels wider when you put them in a 2whl axle and they will rub the inner track nubbins cause the wheels set wider apart from each other than they should making it hard to center the track. True or not I just decided to run what came in the kit since its all New anyway. the wheels, axle, aluminum spacer, plastic spacer outer bolt w/ coned flex washer and outer centering aluminum pieces that align in the axle slots are supplied in the kit , but the plastic spacers that go between the wheels and the inside of the rails are needed, the adjuster bolt and nut is reused from the rev but new xp outer tensioner straps are needed cause the bolt patter spread it narrower on the xp straps, also shorter bolt from the Rev thru the straps can be reused and new nuts are supplied in the kit. New rubber bottom out bumpers for the rear scissor are supplied in the kit but shorter bolts thu them are needed cause the rev ones are to long but the washers can be used and the nuts cause I didn`t see and 4mm new nuts in the kit, the front rubber bottom out bumpers are needed, I used the Rev ones put them over the rails and had to drill a new hole thru the rail cause the holes for the xp bumper are farther down I reused the rev bumper bolts, washers and nuts. new limiter strap, bolt big thin flat washers and nut is supplied.
After I got the skid all assembled I needed to have the ctc tunnel mounting point set as correct length as skid was out for measurement purposes so I purchased 4 thin aluminum yard sticks and drilled 2 holes in each one (ctc holes) so 2 stick with holes drilled 32inchs apart from each other Rev and 2 sticks with 30inchs apart XP then I put the New mouting bolts suppies thru them so I could have the ctc correct on the floor. One tip on all the mounting bolts I took them out to my bench grinder and wire wheeled ALL the yellow locktite smeered around parts of the thread this makes the bolt impossibly to spin in the cross shaft my had and I would rather put my own liquid lock tite on not the crap already on them, then I sprayed them and the cross shaft threads with PB Blaster or any spray lubricant and they spin in and out with your fingers.
Here is a pic of the axle bar sleeves 2 new bolts, washers and shock eye sleeve.
Here is a pic of the sleeve in the shock lower shock eye and the front arm lower axle bar slid thru the shock and sleeve
Here is a pic of where the axle bar and sleeve go
Here is a pic of the outer LH strut rod, axle bar shock sleeve, shock, RH strut rod and needed bolt and washer and how it all goes together.
Here is a pic of the upper scissor strut rods, 2nd axle bar, 2 needed bolt and upper shock position put together just didn`t have new nuts installed and tightened in this pic
Here is a pic of the Rev shock and complete lower shock shaft installed
Here is a pic of the lower part of the rear scissor w/ rev thru bolt, inner spacer sleeve, inner and outer washers installed
I am reading a thead on here entitled Broken T Flex motion and it shows pic and explainations of this lower scissor part broken from a few members on here most just by riding on bumpy trails and not extreme riding like big hard landings, jumps or drops. they seem to be breaking at or above the welds where the triangular upright side pieces attach at the loser tube. After inspecting this piece myself I Can see why this would be the weak point of this skid design. So I am going to remove this piece this week and weld some reinforcement pieces in it I have already figured out how I`m going to do it and will post those improvements here and on the other thread also.
