Be patient with a newbie here....is the pivot shaft threaded into the frame on the left side? If so, what size allen wrench do I need to remove it? In the process of servicing the swingarm I'm using the centerstand to support the bike. Unfortunately I guess you need to remove the centerstand to service the rear shock link. Oh well, next time.

 
It threads into the frame on the right side. Same socket that fits the front (or rear, can't remember) axle fits the shaft. I use this stand to support the bike when I can't use the center stand.

Tks for the help. I tried the tool and it wouldn't quite fit...must need a little bit of a fiddle.

 
Yep, Front axle hex tool (or reversed spark plug socket) fit's it. If I remember it right, it screws into the right side frame & there is a right side retaining nut on it (behind the removeable disk) along with the left side retaining nut. Boreing writeup below...Later,,, De

Lessons learned from rear linkage lube. My ’04 FJR1300 is about 1 year old and has 9000 mi on it and I have ridden thru many rainstorms here in the Hotlanta area. After reading the many horror stories of rusted/non-greased parts, I bit the bullet to lube & inspect & here is what I found. Working from a 3’ high lift is great & having an overhead hoist above the lift is even better.

#1 Things needed: a 19mm hex socket (removes the front axle also) to remove & re torque the swing arm pivot shaft, a set of torx sockets for the one torx bolt on the front of the shifter mount, a good set of 6 point metric sockets (large ones too for re the swing arm pivot shaft nuts), a good set of combination metric wrenches, the factory service manual for the assembly pictures & torque values, a copy of the https://www.fjrtech.com/ article on lubing the pivot points for the instructions.

#2 There was no rust or fretting corrosion on any thing and all splines & bearings were greased & all shafts had a light coating of oil on them. If I had known this, I would have waited a few years to do this job.

#3 The center stands on the pre ‘04s (with their extra added gusset) may break, but they darned sure won’t fall off because of loosened bolts. These 4 bolts & nuts were the tightest & hardest to loosen of any I have ever seen. These 4 bolts were inserted from the outside, so the exhaust system has to be pried over & down to remove the bolts. While the book says to remove the exhaust system, you can do it without removing the headers by removing the muffler bolts & exhaust bolts to the center stand. When remounting the center stand, insert these 4 bolts from the inside so the exhaust won’t interfere. On the front 2 bolts I used a thick flat washer under the bolt head and purchased 2 thinner nuts (blue thread locker too) for proper exhaust clearance. I made sure that the weight of the bike was on the center stand before tightening these 4 center stand bolts/nuts.

#4 Remember which way the relay arm (the dog bones attach to the center of this) goes or you might have “falling rate” suspension. The arm with the bend in it goes to the back & is hooked to the Shock. A while back someone posted pixs of his relay are where he added grease fittings to it but I elected not to do this because I couldn’t see how the grease would get by the outer race of the needle bearing unless these bearing housings have a grease hole in them. Any ideas on this, guys & gals? Is there a hole in the bearing housing? I do believe that a grease fitting will work where there are 2 needle bearings separated by a space as in the center of the relay arm and on the swing arm.

#5 Remove the right muffler & the swing arm will have enough clearance to drop out.

#6 Didn’t pull the drive shaft out of the rear end cause it gets it’s lube from the rear end. Did remove the “U” joint and lube both splines with Moly lube. Looks like the “U” joint could go in either way but the splines on one end have a lead in bevel to help when inserting the drive shaft.

#7 Single best improvement was from lubing the shifter arm pivot, but it wasn’t from the added grease. This pivot is a shoulder bolt w/2 thrust washers & a “wave” washer & the proper clearance (read no slop) is obtained by screwing in the bolt till the wave washer is slightly compressed. The bolt is locked in place with blue thread locker from the factory. My bolt was too tight & was binding the shifter. You can easily check this by removing the upper shifter arm from the tranny shifter shaft & seeing that the foot shifter arm moves freely & isn’t binding. Mine was way too tight but I couldn’t tell it cause there is no slop in the linkage, until I disconnected it from the tranny. After removing the shoulder bolt & greasing it, I reinstalled it (with new blue thread locker) without binding it. What a difference. It shifted fine before but now it’s like warm butter. This shifter maintenance can be done by itself by removing the “Shifter/footpeg/sidestand” assy but this assy will have to be removed to remove the “U”joint.

 
Tks the further info...many of these points I've discovered the hard way...19mm allen wrench fits with some difficulty but I was able to remove the pivot...is it even possible to remove the two seals without rendering them unuseable? I should know better...probably special order parts...Why is it the tools you have are never quite what you need...3 different sets of snap ring pliers and none capable of removing the circlip. Assuming I finally do get the two bearings out...any suggestions on how to remove the shield from the sealed bearing without destroying it as well?

To make the whole thing even more irrelevant...u-joint, shaft splines, drive and driven gears all well lubricated-no sign of problems. Makes me wonder whether the whole evolution was entirely necessary. I guess if I had an extra grand lying around now would be the time to change the rear shock...but then if I had that kind of money sitting around I might not be doing this myself.

Forgive the frustration.

 
Sealed bearings, if well protected, are usually maint free, but if the shield is of the plastic or vinyl variety, just carefully pry the edge out from the metal lip of the race and have at it. Grease everything up anyway as long as you're in there. And yes, the evolution was necessary-cuz now you know everything is lubed, where before it was an unanswered question. Confirmation has a price. ;)

Bounce, I've seen 2 other pixs of the U joint cover & they are both the same as mine with that odd cut out. Check yours out & tell us if yours is the same. Later,,, De :)

 
Took a "time-out"...moving on. U-joint cover is as Yamaha intended, I guess the cut-out is to ease removal of the u-joint.

Better snap ring pliers...snap ring out but bearing won't budge. In the excellent descriptions on FJR-TECH and Bikes-Spikes there's no reference to removing the bearings....are they supposed to be serviced in place...or is there a trick to removing?

Tks.

 
Sealed bearings are... er... sealed... clean the area of crud, lube the assemblies, and put it all back together unless replacing the bearings. If the latter, then drive the bearings out using standard tricks (sockets and mallets, etc.) and no worries about the condition of the removed bearings since they are breing replaced anyway.

Installing the new bearings, typical advice: be careful and don't ruin them. :blink:

As for the cutout... looks like you're right. I didn't have a side-on view of mine but the cutout above looked pretty ragged instead of being part of a mold design. My views were from the back and up over the headers.

Interesting that I took a pre-removal photo but not of one after the footpeg bracket was gone and the large nut was exposed (no... not TWN).

Not sure what I expected when it came to removing the bearings...but I went ahead and bought replacements not knowing what I would find so I'll "persuade" them out and go from there.

 
I don't know if this is applicable here, but my experience replacing bearings where the races are separate from the cage is to use the old race to drive the new one in. Just line the old one up against the new one and tap on the old one.

My question to Bounce. Your pictures show the servicing of the swingarm without removal of the centerstand.

Is that possible, or removal of the centerstand is mandatory.
