| + | 86-88 models are shown to have two bearings and 89-03 models with only one bearing in the catalogs. \\ | ||
| + | However, two bearings are used in 86-03 Sportster swingarms and they are both installed on the right side pivot.

| + | Both left and right sides were described as having bearings until the 2000 parts book came out correctly describing the left side as having a bushing. \\ | ||
| + | The part number for the bearing (set) changed in 2000 from (47082-81) to (48367-98). \\ | ||
| + | According to the pics on the [[https://www.jwboon.com/index2.php?co...rtster/Page_15|JW Boon]] website for NOS parts, even though the part number changed for the right bearing, it appears to be a place of origin change. \\ | ||

| - | * Having to replace bushings and bearings related to motorcycle suspension has been a normal maintenance routine since the beginning of time. Keep in mind the rubber mount design also has 3 stabilizer links that connect the engine to frame and allow vertical movement from engine vibration, but also maintain side to side alignment of the engine and frame. Make sure they are tight. In addition, there is a pivot shaft that supports the swing arm bearings/bolts on the outside, and goes through the rear mounting lug on the tranny case. If the pivot shaft is loose in the rear mount lug, it will need to be replaced also. Lube and properly tightening steering head bearings are also important part of the process.

It's got some "flex" stock most don't notice it... Till its really bad! ((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=3)) | ||

| - | * You can use a couple small automotive scissor jacks, one towards the front and one towards the rear, to support the weight of the motor and give some flexibility in moving it around to line things up. ((sportsterpaul http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=10)) | ||
| - | * The front right is a pain to pull out, you need to pry the motor an inch to the left... right up to the frame, remove the front pipe and a couple case bolts underneath. Even with the engine right up tight to the frame it is a pain to pry the old mount out. Once out, the new one slipps right in. ((JohnK http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=6)) | ||
| - | * Use a 6" C-clamp to pull the front of the motor right up tight against the frame. You cut the puck off the end of the threaded rod part of the clamp, and now it has a round ball on the end of that clamp. You use that round end to keep the C-clamp from sliding off the frame as you tighten it and pull the front of the engine over towards the left side of the bike (the ball on the clamp is inserted into the hole for one of the support plate's bolts). So when you get it pulled all the way over to where it contacts the frame as you mentioned, you just keep turning the clamp and somehow it pulls the rear of the engine over just enough to where the mount will fall out on it's own if it's sitting at the right angle. ((wedge http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=21)) Don't lift the front too high else it will hit the frame before it is over far enough. ((JohnK http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=10)) | ||
| - | * Remove the rear mounts and then change the fronts. Getting the right front out is easier when the tube is removed from the old mount. You can get loads of hassle getting the drag specs fronts in and having the extra movement by not having the rears in place will make it easier. Disconnect all the stabilizer links and put a jack under the front of the engine while someone sits on the bike to hold it upright and used pry bars to get the thing to move enough. ((Loony http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=6)) | ||
| - | * It's best if you RUN the motor with the mount bolts loose for a few revvs then torque them to factory spec to let the engine settle in the mount. ((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=19)) | ||
| - | * Front mount- There is a "shaft" on the RIGHT mount if it (there is actually 2 "shafts") but removing the SHAFT from the Right mount will make things easier. If you have forward controls, remove them and the above is correct remove the "dog bone" mounts it will help you "move" the motor to 1 side. If your mount is really bad out of shape it will be HARD to remove the "LEFT" mount and the right will be almost impossible... REMOVE THE SHAFT with a LONG punch then remove the rubber bushing... now you should have enough room to install the front RIGHT mount. Align it and install the left mount... reinstall the dog bones. ((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=6)) | ||
| - | * REAR: Remove the rear brake line it will help... and on the rear mounts they will come out ALOT easier than the front... even with removing the swing arm... ect. i found it to be ALOT easier than the front mounts. Take your time with the rear. The REAR shaft that goes through the engine that holds the RIGHT mount in place... and replace those TORX with some grade 8 hardware and tighten them down... TIGHT!!!!! they tend to brake if they come loose...((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=6)) | ||
| - | * The LEFT mount will not come out easy if it is OUT OF ROUND. Turn it like 180deg and out at a angle.. it helps to REMOVE THE LOWER dogbone and rock the rear of the engine around... the NEW "round" mount will go in much easier... the RIGHT mount should not be a problem it will slide out once the AXLE shaft (the one with the 3 screws that break) is knocked out.... it doesnt matter the "shape" of the old mount it will come out pretty easy... but the primary and the frame will create some issues getting the RIGHT mount out IF it is droopy.

| - | * OEM Mounts: | ||

| - | * If you don't want more vibration, use the H-D mounts, but plan on replacing much more often. ((Nytstr http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=8)) | ||

| - | | ||
| - | * Drag Specialty Mounts (Poly): | ||
| - | | ||
| - | * The DS mounts seems to be slightly stiffer than the HD mounts... The HD mounts seem seem to soft and don't seem to last long I bet there are alot of sportsters with softened mounts or saggy that needed replacement. ((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=7)) | ||
| - | * The reason for using solid motor mounts is to increase chassis rigidity to facilitate improved high speed stability and handling, however, the use of solid motor mounts will contribute to accelerated wear of the motorcycle chassis components, which may in turn lead to the breakage of the chassis or powertrain components. ((kroon http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=2)) | ||
| - | * If it was questionable to use the nylon motor mounts and if they could cause frame failure, since the rubber-mount frame is heavier gauge steel to begin with then I don't see it. ((wedge http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=8)) | ||
| - | * I notice the extra vibes at idle with the DS mounts, but I don't feel any difference above 2k. The bike just seems happier, and although I can't quantify it...it is smoother and seems to vibrate less at speed.
