The Guy on EBay selling these rubber grommets has included the 3D printer files on his eBay site to download for free! Includes the material selection for the filler wires to make them malleable.
This has got me thinking, what's to stop us from making our own on a 3D printer? I could draw the dimensions from any rubber object, it's really not difficult, as long as it's in reasonable condition and mostly there, then a prototype can be printed, and from that a mould can be made.. Grommets, air filter joints, all the N L A parts needed for a restoration!
Just a thought.
Nigel.

Hi Ash, sorry for the delay in replying to your question, there's nothing wrong with my bearing, but I have the chance to get some made, by a bearing manufacturer, In small quantities. They want a bearing to measure before they quote, and I was a bit reluctant to send them my only bearing. I've sourced a scrap countershaft with the bearing on it, which they will have later this week, and I'm waiting to hear what they will cost. If they're reasonable I'll get some made.
Regards,
Nigel.

That's good news Oddjob, my contact has just asked how many do I need! I'm still waiting to hear back! If they have got them I expect they will be a similar price.
The next thing is they mentioned that they could consider getting these bearings made as a run. They couldn't tell me a price for that yet, but it wouldn't be too high, minimum run though is 1000 pieces.
Next question is how many forum members want one of these bearings? Actually want, rather than would like? I know you and I want one, and I think Ash would want one too, I'll wait to hear from the bearing factors Monday, and keep you posted.
Regards
Nigel.

Hi Oddjob, I'll keep you posted, I am following a lead in Japan. If they become available I'll let everyone know. I have found 25x57x28 double row axial bearings, but without the snap ring groove, with rubber seals, and these retail about £300 + VAT! The right diameters but too wide for our needs.
Regards
Nigel.

Thanks Oddjob, somewhere in Japan is a small warehouse with lots of little red boxes with a wing on the side and marked 91001-283-000; made by NACHI, and stamped 258651!

Thanks Ash again, hoffmann (Orinoco bearings) are very helpful people, and are looking into it for me. I will have an update by Friday they say.

Thanks Ash, I've looked at your parts manual you kindly supplied as a pdf, but the manual shows both bearings to be the 5205 52 mm size, and when cross referenced with the snap ring those are both shown to be 52 mm. Too. I have two new bearings of that size; one for my 350/4 and one for the 500/4.
The one I'm after is the 57 mm diameter, it is available with the shaft, but with it being so rare the price is high too... I might just have to bite that bullet 😟
I wonder if the members who have grooved a new bearing could comment on how they achieved that, and whether the new groove was machined or ground? I expect the swarf to be a hindrance, and with the outer race being hardened did that pose any difficulties?
Finally, what bearing did you use? I've tried googling the dimensions for a double row 25x57x24 with shields and got nowhere, so thought about a sleeve OD57 ID52 24wide with a cruciform cross section and split like a white metal big end/ main bearing to locate one of the 5205HS bearings as the ID of those is 25 mm and does the same job.
Do you think that is a possible solution? The only problem I can think of is the 5205 width is different.
Regards
Nigel.

Hi guys, I've stripped down my gearbox and found two different size bearings, though the parts manual says they are both 5205 bearings which have a 52mm Dia. One of them is a 5205HS ( HS for high speed ) I know from previous posts that there was a misprint in the 500/550 manuals. I have sourced the 5205 52mm bearing, p# 91002-286-008; there seems plenty of those about, but the countershaft bearing #91002-283-003. (57 mm dia with snap ring groove) seems unobtainable. I've tried googling the bearing, and no-one seems to have them anymore. The bearing I have is a NACHI 258651 25mm inner dia, 57mm outer dia, and 24mm wide. The snap ring groove is central, 2mm wide and 1.15 mm deep. The experts may correct me, or confirm these measurements! Fortunately, mine is in good condition. I have seen countershafts for sale with this bearing fitted, but none available singly. I've found out that 5205 as you would expect means 52 mm outer dia, and the 05 means 25 mm ID, so I tried googling 5705, no luck.  Honda must have had thousands of these bearings made, possibly even millions! So where have they all gone? Any ideas? Also, can anyone explain what B/brg N/rad N/com on CMSNL website mean? I'm guessing ball bearing, nominal radius, but I'm stumped on N/com! Regards Nigel.

Hello, I've spent a whole evening looking at all the posts in the 350/400 section for an answer, to no avail. I need to replace the fork oil seals on my 350/4, but can't see how to remove the chromed lower cover from the lower fork leg.
I can see two small spigots and a slot, and some holes. The picture below shows that the cover isn't threaded, so how do I remove the cover, I have heard it's like an eighth turn bayonet fitting, or is it a screwdriver twisted in the slot, or drifted out, and the final option, a C spanner in the hole?
Thanks
Nigel

Hi I'm restoring a 72 CB500/4 and a 72 CB350/4, a 76 CL450 twin, as well as a CB360 twin, so my leisure time is mapped out for this winter.
I'm from Weymouth in Dorset, I am a Scuba Diving Charter boat skipper, I'm not married and have no children, so I have no competition for my time.
I've completed the cycle parts on all the bikes, and now have to do the engines, that's the fun part for me. I've fitted LED bulbs in the indicators, and tail lamps, as well as the clocks, with the exception of the turn repeater which I left as an incandescent bulb. The headlamps are traditional incandescents for now.
I've bust a cylinder stud on the 500, and a PO has snapped off a bolt in the 350's sump. Apart from that, so far there are no problems that haven't been overcome. The Carbs were full of something organic, and it wasn't dinosaur bones.. ....I've fitted new tyres, new exhausts, 8 silencers and down pipes..that hurt my wallet! New seats, wiring harnesses, and loads of parts.... Still have to paint the tanks and side panels.
I'm glad to be a part of this forum.
Nigel.

If it helps this is my breather tube, the outer sleeve is hard and brittle but this was how it was fitted to my bike, I haven't removed it yet as it will be destroyed when I split the crankcases tomorrow.
