In the meantime, I'm giving this a try. Cant beat Amazon at $3.00 for a try. From a Honda ST1300 dirtbike. Ordered it today to my local MC parts store.
HONDA 91209-MCS-000 OIL SEAL (8X16X5.5)
I was looking around scp's site today and stumbled upon this service for abs rebuild so maybe they have some leads for supplying you're needed parts. https://www.supercoupeperformance.c...ator-master-cylinder-assy-remanufacturing-568
Used this service last summer from Bill. Worked out well and I was pleased with the results.
Not sure why they claim the pressure switch is obsoleted, tho - I replaced mine just a few months back and had no issues finding a new one (and a slightly used tool to make the job easier).
Good news. I was able to place an order for a run of seals. These will be in the common 8x16x6 size, double lip, but made in EPDM.
There will be only two differences from the original seal:
- The original was 5.5mm tall, but this seal is 6mm. I don't think this is any problem, as the housing bore is tall enough to take the extra 0.5mm.
- The original had a ribbed outside diameter (OD). These replacements will have a smooth OD. The ribs are supposed to make offer slight advantages, but I think the plain OD will work well enough. The ribs seem to be more for situations where housing tolerances are loose, but these housings seem pretty nicely made. Getting the ribbed OD would have quadrupled the cost of the order because of setup costs for new tooling. So the benefits didn't seem to justify the added cost.
There is some lead time for this order. I was quoted 8-10 weeks.
Before the seals come in, I will start a new thread, either in the "New Products and Services" sub-forum, or in "Parts for Sale". I will add specs and pricing for anyone who is considering a purchase. Pricing is yet to be determined - I know my costs for the order, but I haven't sat down to figure out exactly the best way to ship these. Quantity discounts could be arranged too. In any case, the price of a seal will not break the bank - trust me. This is not a scheme to get rich quick (or even slow).
I am considering ordering a small quantity of appropriately sized motor brushes and terminals. By the time a seal is worn out, the brushes are probably close too. To open the motor and replace the brushes is a little bit harder than just replacing the end seal, as you can tell from the pics in the original post. You need a decently powerful soldering iron and some experience. One of the terminals is standard, but one is special, as it incorporates a thermal breaker. If you break that, I don't know where in the world you would buy one. So you do run a risk of ruining your motor if you tackle the brush replacement ... but the motor will eventually stop working if you just ignore it. Also, if you let the brushes wear out, the brush holders can drag on the commutator and get damaged, which is not good either. For reference, I would say that the brushes shown in the first post are at least 80% used up.
I am not very interested in starting a rebuilding service for these, as I am really just an amateur. If someone wants a rebuild service, they should try contacting the usual SC vendors, like Bill at www.SuperCoupePerformance.com. Or call Jose who is mentioned earlier in this thread. He is a real pro at this.
I am just trying to help make parts available where they are needed, and to let others take advantage of the experience I gained through trial and error.
Did these ABS pump motor seals and brushes very become reality? If they did, I'm in need of the seals and brushes.
