86 Aspencade speedometer gear

Postby tbeiler » Tue Nov 24, 2015 9:13 am



Guys, my speedo gear is pooched. Plastic gear fragments in the assembly.
I have seen the entire box assembly on ebay (part # 44800-MG9-013), but my housing and internal gear are fine once I got the plastic fragments out.
Is the plastic speedo gear (part# 44806-MG9-003) available anywhere, original or aftermarket other than ebay. Be great if anyone has any info on where to get one of these.

If they simply are not available, I'm sure someone has had the idea to duplicate these gears via prototype printing.

I'd be very surprised if they are available. Printing one is a possible option, but you would have to make sure it's done in nylon (for strength), and with the resolution to ensure the teeth mesh correctly. It might need some hand finishing work to get it just right.

Even the nylon or plastic gears dont normally just break. Did it get bound up some how? Cable frayed? Speedo head gears get jammed? I would do some looking before just replacing.

Hey twocams - mine is the Aspencade with electronic dash so I don't have the cable or speedo head gears. What you describe is for the Interstate models.
The Aspencade has the plastic gear in a metal housing attached to front wheel which reamins statioanry while wheel is turning. The palstic gear is always spinning when bike is moving, Plastic gear then turns another steel gear at a right angle to plastic one and to the steel gear is attached a metal arm which then attaches to the speed sensor. The sensor electronically sends info up to dash and presto bingo speed is registered.
Cant' say why the plastic gear has worn down, but since it is always spinning against the steel gear, guessing maybe a few bits of plastic stopped the steel gear from turning momentarily, shearing more plastic off and then kaboom, catastrophic failure.
Went to Honda shop today, you can't buy just the plastic gear, you have to purchase the whole assembly. They said by January you should be able to order the assembly, around 100 CAN.

very common for the plastic gears to strip on the speedo I found the gears are not available, but a new whole gearbox is still.

Shoot am I wrong again? Thats 3 times now in the last 66 yrs. The other 2 were when I got married. :lol: I bought my 85 Aspy not running so when I saw the milage without turning on the key. Just assumed it was mechanical. But the wiring digram shows its electric....humm, go figure. And that my excuse.

Too funny there twocams. Way to bow out gracefully.
Getting to learn something new all the time and have some fun at the same time is what this site is all about.

Now to get a replacement gear (not avaialable apaprently) or a complete box assembly, (apparently available), just checking sources now.

So how is the gear lubed? Do you need to put grease inside once in a while? i would say look for a used unit but it maybe half worn out. (gear).

Yes, lube is required, pictures were taken after I cleaned them up with varsol. I still have a little sticking when I turn the internal gear. I'll try and get it out, but since I'm stuck getting a new assembly, the old housing will be a paperweight.
I'm guessing that since it is attached to front wheel, bearing grease would be appropriate.

yeh the new gearbox comes with some grease applied, but the mechanic who put mine in, suggested it needed more, and put more in.

I may have to look inside mine before I put it on the road. And give it some TLC...and grease too. 8-)
Thanks
