rear wheel

[mustang071965]

i replaced my rear wheel bearings yesterday. no failure just age. after completing the tire turns easy no snags in forward. rolling it backwards tire makes 2 revolutions and then slight snag then goes on. is this normal when rolling tire backwards.

[Jess from VA]

That may be your rear brakes. 

I'd take a bit of a ride after reassembly before doing any investigating.

Up on the lift and do some close observation testing, spinning, listening, looking.

You didn't hammer those new bearings in did you?

[mustang071965]

negative. im a heavy equipment Mech. i used my press to install.

[mustang071965]

should have said my hand screw press. not a hyd press.

[Joe Hummer]

As long as you press/beat on the outer races, you should be fine.  In what position was your swingarm during this test?  If it was hanging down off the shocks, you could have been hitting the u-joint...but I would think it would be the same in either direction...so...dunno.

bike was up on lift, tire resting in full hang position. tire when spun forward smooth spine very little effort. spinning backwards very little effort smooth for first 2 revolutions. then slight drag and then back to rolling smoothly. could it be just the way the gears are made? normal run is forward no such thing as revers on the bike.

[Ricky-D]

Nope!  Absolutely not.

The wheel should turn in either direction with same resistance.

There is nothing in the design/engineering of the bike that will cause

what you infer.

then can you point me toward possible cause Ricky. could it be slightly miss aligned when i put my  wheel back in? i read other post on backing off the 4 bolts on the shaft to final drive housing. that was not in my manual. i plan to re due the tightening of the rear tire this weekend. will back off the axle nut then loosen the 4 bolts on the shaft to gear housing. then torq the axle nut to 81lbs and then the 4 nut to 41lbs. hopefully that maybe where the problem lies.

[Jess from VA]

Good idea. 

I have no idea if it could be a very early sign of a ujoint issue (slight kink).  But only in reverse makes it baffling.

It may be one of those things that will not show itself (if at all) until more miles are put on.

Shocks off? Even with shocks on the swingarm is hanging lower than if
the bike was on the ground. There's a certain point where the swingarm is
hanging low enough to cause the u-joint to bind...

[mustang071965]

shocks on. shocks set to 4 position ( when wife rides with me ) turns nice forward no snag. just slight snag going backwards after tire makes full rotation. then turns freely again for another full revolution then slight snag.

[mustang071965]

also plan to raise the rear tire with bike on the lift and see if possible it could be from the full downward hang of the tire. still plan to re due the tightening of the rear axle with the loosening of the 4 bolts on the final drive just for peace of mind.

Hang far enough down and you chance cracking a bearing cup edge in the universal joint.

You'll hear it if you do it.

thanks every one for the replies. any one else have more ideals of where to look keep them coming. as i said will re due all over again and raise the wheel up from hanging position and re spin by hand again.

[Jess from VA]

I was always told to NEVER spin or move the wheel when the swingarm is hanging down with shocks off, and keep it in gear so it cannot happen in this position.  Or risk damage to Ujoint.

[mustang071965]

Jess shocks are on for all this. the tire is hanging down by the shocks when the snag happens in reverse. did not check the spin of tire till had every thing back in place then removed from gear and checked spin.

[Jess from VA]

OK.  I've got nothing else. 

[mustang071965]

i thank you for your help Jess. if you think of some thing please share. all help is appreciated.

[Jess from VA]

Again, a tiny warp or defect in the rotor could do it....... but you would think in BOTH directions, and not after two clean spins.   I am still thinking brakes, somehow, someway.  The pads float on pins that should have grease on them. Plenty of past reports on corroded pins causing various symptoms.

Do your reassembly of the four bolts, then go 100 miles (perhaps staying close to home), then test again.

[Ricky-D]

Easy enough to remove the caliper and eliminate that from the list of causes.

I'm still saying the U-Joint is what is causing this.     The wheel is too low and it is putting a bind on the reverse move.

Put a ratchet strap on the swing arm and pull it up about 3 or 4" and see if you still have the little hesutation you refer to.

Keep us updated and let us kow what you found to cause this,

[mustang071965]

plan to jack tire up to normal ride position then check for snag this week end, also going to redo the tightening seq for the axle along with loosening the 4 bolts on the final drive before torq the axle nut then tighten the 4 bolts. will grease the brake pad pins to. thanks all will let ya know the results.

Additionally when you redo the tightening sequence, its ideal that the right shock is removed from the final drive

[Ricky-D]

Honda designs the Valkyrie rear drive line and assembly to be in as straight a line as possible under normal loading and running condition.

That means the universal joint is not really having to do, what it is designed to do, but rather imitating a solid connector.

It is, under all other conditions of riding, that it is necessary to have the universal joint.

That being so, there is an inherent problem with the employment of a single universal joint in a drive line.

Velocity will occur within the universal joint that is non-linear and could be interpreted as an unevenness.

On a worn in system (the drive line) it is possible that there could be felt a smoothness of operation, in

the direction of normal operation, and a different feel when rotated in the reverse direction.

The feeling of "unevenness" could be exacerbated with the driveline in an unusually angled position (note 1) and more so

with a worn universal joint, although not to be confused with a worn out universal joint however.

thanks alot Ricky D.

morning. well decided yesterday to re due the rear tire adjustments sense i got off work early. first i placed  a jack under the left side of the swing are to raise the weight off and removed the shocks to allow the wheel to be compressed back up into the fender as if it where on the ground under its own weight. then i spun the wheel by hand forward and then backwards. well what do ya know slick as owl snot in both directions. with the shocks on and the bike on the lift the shocks apply enough downward pressure to cause the drive shaft to snag in revers. after regaining my peace of mind that i put every thing back right the first time, i still raised the rear wheel and loosened the axle nut then the 4 bolts on the final drive and then torq the axle nut to 81 ftlbs and then the 4 bolts on the final drive to 41 ftlbs. also sense i have a dry moly lube i use on the heavy equip i work on i sprayed the brake pin and coated it to allow for no binding. ( the spray is for metal to metal contact and dries in about 30sec leaving a slick surface ) so i would like to thank every one that took the time to read my post and give me there opinions on my problem. that is the main reason i became a member here after buying my valk. thank you all.
