did they use the yz 426 bearing kit in the swing arm?

[250x_kyle]

yes.

The Houser Swing Arm uses bearing Part # 132003, they are $6.80 each, you will need 4. The Bearing Sleeves, Thrust Bearings and Dust Caps are Yamaha Pivot Hardware for the late 90's four-stroke dirt bikes (YZ426F, WR400F, Etc.) Those parts can be purchased at any Yamaha Dealer.

so they didnt use the 400- 426 bearings? is that a houser #

[250x_kyle]

that is a houser parts number. the way he made it sound was that any late 90s dirt bike swingarm bearings would work.

[motochamp250]

with a little google fu, that part number came up to a link on houser's site.... fwiw

[250x_kyle]

was that english lol

[motochamp250]

haha i'm not sure either dude :blah:

sounds to me like you need the houser actual swinger bearings, with the dirtbike bearing sleeves thrust bearings and dust seals.... how I interpreted it....

[chopp124]

pretty sure the whole 426 kit is what they used i will post if it works. im still trying to understand the motor mounting issue why did they mount it at a backward angle im wanting to cut chassis and change that but not looking to do that much work

[250x_kyle]

possibly a tank clearence issue. havent a clue on that one. but i pressed the yz426f bearings in and they went in just fine they were a little shorter then the houser bearings. i didnt eve think to mic them before i put them in to see if there was any difference.

[chopp124]

if u used two bearings i think its fine im doing the same and i figured out the motor issue laegar did it to. the travel on the dirtbike and the atv is almost the same however the dirtbike has a much bigger sprocket so the angle of the chain doesnt change as much by angling the motor it helps the angle when the swinger drops. i have that issue with my gibson chassis they get real loose when the swing arm dropps but it hasnt ever caused a problem. im mad cause the bottom of my motor is lower than the frame rail one good bottom out and case is junk

[chopp124]

my buddy was going to do that when he made the gibson chassis but east coast wanted the motors lever wich i like as well. he just told me thats why the motor is like that. this is a 426 chassis and i put a 450 in it the bottom is lower and sticks out because of that. it could have something to do with the tank too i guess but my buddy just angled the tanks on the gibson chassis

[250x_kyle]

makes sense. minor modifications can change alot of different things. i need to pick me up a miller tig and a jd2 bender.
