danevans Posted July 29, 2017 Share Posted July 29, 2017 I have lost the tiny split springs that pinch the fingers in my right side mirror. They are not available from BMW. Anybody want to sell me a couple or give me a lead on finding some? Many Thanks! Link to comment
PAS Posted July 29, 2017 Share Posted July 29, 2017 You will need to find the I.D. and do a search. Link to comment
kioolt Posted July 29, 2017 Share Posted July 29, 2017 Try McMaster Carr https://www.mcmaster.com/#circlips/=18pnez4 or https://www.mcmaster.com/#circlips/=18pnf83 Link to comment
Roger C Posted July 29, 2017 Share Posted July 29, 2017 I had the same problem. I solved it by twisting a couple strands of 16 ga. wire and wrapping it around the spring fingers, just tight enough that the wire would not come off. Then when installing, rub the spring fingers with wax. So far, so good. Link to comment

danevans Posted July 30, 2017 Author Share Posted July 30, 2017 Many thanks to all of you. I am not sure which I will do. Link to comment
Selden Posted July 30, 2017 Share Posted July 30, 2017 I have a related, but different problem: one of the four "petals" on the receiver snapped off from fatigue. As far as I can see, this part is not available separately from the entire mirror base assembly. Fortunately, the mirror stays on quite well, despite the damage. Link to comment
PAS Posted July 30, 2017 Share Posted July 30, 2017 I hate the idea of wacking something to install or uninstall. Link to comment
danevans Posted July 31, 2017 Author Share Posted July 31, 2017 I ended up cutting a coil from a small door spring. I then took off the other two springs and tightened them up a little, then pushed in the "fingers" a little as well. I wrapped a small amount of Teflon tape around the groove of the stud. Tomorrow I will attach some baling twine (easy to find in Kansas) for the purpose of not losing the mirror if it does come off. Thanks for all of your replies and ideas! 1 Link to comment
Mike279 Posted August 1, 2017 Share Posted August 1, 2017 I see fuel lines on old dirt bikes that have that type of spring. Some small engine fuel lines too. Should be able to scrounge one up. If not my CTX 1300 uses a similar mirror clip(four petal with wire spring around it), Honda Part number 88115-MT3-000 for 4.10 each. I used some stranded steel wire with nice crimped loops to insure the mirrors stay close to my bike. Most people around here have a knife that cuts baling twine a bit too easily. Mike Link to comment

Mike I must be missing something. People would cut your tether lines? for what purpose? Link to comment
MarkAZ Posted August 1, 2017 Share Posted August 1, 2017 I use long zip ties as tethers. The goal is to keep from losing the mirror assembly if it comes off while riding. I suppose something more substantial would help prevent someone from stealing the mirrors but that's not a big concern for me. Link to comment
Mike279 Posted August 1, 2017 Share Posted August 1, 2017 Tethers are cheap insurance with mirrors becoming hard to find. Steel cables give me peace of mind. I tether the helmets too if I can't see the bike. I watched a guy who lost his boat trailer at the lake one day. I thought I really don't want to be that guy. Mike Link to comment
PAS Posted August 2, 2017 Share Posted August 2, 2017 I dont see the spring on the Honda part. Link to comment
Mike279 Posted August 2, 2017 Share Posted August 2, 2017 Here is an Ebay ad with a picture. Honda parts shows the same part number for my 2013 CTX 1300D mirrors for less money. http://www.ebay.com/itm/New-OEM-Honda-Washer-NOS-/252783007703?epid=1211843652&hash=item3adb0a97d7:g:4BcAAOSwPh5ZGraF Mike Link to comment
PAS Posted August 14, 2017 Share Posted August 14, 2017 Has anyone tried these Honda parts? I have two holders with broken fingers. Link to comment
Roger C Posted August 14, 2017 Share Posted August 14, 2017 Yeah, $4.10 from Honda Parts House plus shipping vs. $12.15 w/free shipping from ebay vendor. Surely one could order from your local Honda dealer and have them shipped for free to the shop. If my gerry-rig wiring fails, I'll try the Honda ones. Link to comment
Mike279 Posted August 15, 2017 Share Posted August 15, 2017 I took a close look at my mirror on the RT and the connector has six petals with a wire around it. The honda has four petals and a rolled edge. The RT's use a rivet and the honda a screw. The male pins are slightly different with the engagement point a bit farther out to accommodate the screw head on the honda part. It won't be a perfect match but it should be workable.

Roger C Posted August 15, 2017 Share Posted August 15, 2017 Last time I looked at a parts fische, the plastic insert in the mirror housing, to which the petals and tension wire are attached, could be purchased from BMW for $67 plus shipping. Probably a non-stocked dealer item but available. Link to comment

BobSut Posted December 13, 2019 Share Posted December 13, 2019 (Following up this ancient thread in case it's helpful to someone else who finds it like I did by searching) I too lost one of those little split-ring springs when it ran away to hide on the floor beneath a shelf in my garage. While looking for a replacement my best stopgap was a bread wrapper twist closure wire. But since the wire's not elastic the resulting finger-basket had a fixed diameter. It held by friction along the sides of the post head, not by gripping the post head from behind. I measured the remaining spring-rings at ID=10.5mm=0.413", between 13/32" and 7/16". I shopped the options suggested here. At McMaster-Carr I considered their 91650A350 (Heavy Duty Spiral External Retaining Rings) and at Grainger I considered their 5EB58 / WSM-43-S02 (External Spiral Retaining Ring). I visited local hardware stores where I found nothing similar, but in their nearby drawers I spotted... O-Rings! Not being sure which would work best, I bracketed the exposure by purchasing candidates in an array of sizes. Retail O-Ring nomenclature includes three dimensions: inside diameter, outside diameter, and rubber thickness. Three is redundant because you can always derive the missing dimension given the other two (OD = ID + 2*Thickness). I only needed ID (how close it would squeeze the fingers together when the mirror is off and the spring/rubber is relaxed) and Thickness (how tightly it would grip behind the post head when the mirror is on). I got samples of metric ID=8mm 9mm 10mm Th=1.5mm x x x Th=2.5mm x x x and imperial ID=1/4" 5/16" Th=1/16" x x Th=3/32" x x Th=1/8" x x After test-fitting several I decided on 9/16 x 5/16 x 1/8, available in my nearby hardware store as the Hillman 780014. The mirror housing pops on and off easily, the grip is snug, the housing is stable, and the image in the mirror is as clear as it has ever been. You might find another size fits your bike's mirror baskets better. I wish I had thought of this for my K100RS, with a similar mirror housing mounting mechanism though the posts, baskets, and spring rings were a different size. These O-Rings are made of Nitrile (Buna-N) rubber and sold for plumbing applications, so they should be weatherproof. My only concern compared to the original steel spring-ring: This Nitrile material normally serves under constant compression, so I don't know how long to expect it to last in this application under varying tension.

Miguel! Posted December 14, 2019 Share Posted December 14, 2019 Brilliant! So you didn't try the springs at Grainger or McMaster then? I'd check the o-rings a few times through the year. Please keep us informed and let us know how they are holding up. Best Miguel Link to comment
dirtrider Posted December 14, 2019 Share Posted December 14, 2019 Morning ____ Over the years I have repaired a few of those missing/broken garter springs on the mirror post clips. "O" rings do work (I usually use 2) but over time ozone & heat degrade them to the point of poor retention. Probably be OK if the "O" rings are replaced at every mirror removal. Best I have found (so far) is to find an old tension or compression spring with approximate wire size & close ID size then use a Dremel to cut 1 coil out of the spring. If the spring wire diameter is slightly smaller then I clip 1-1/2 coils out of host spring. Link to comment
