Rear splines
Here are the sizes and part numbers of the o-rings on the flange. One is on the outside and the other is on the inside probably covered in grease. The inside one is larger.

91358-MG9-003 O-RING (50.5X3.5)

Ok, my reassembly seems to be going pretty well (have drive on sw arm), but a [i]tip[i] that I read on here is giving me a problem. After taking the boot at front of sw arm loose, now I can't get it to hook back over the lip on back of transmission.
Any tips on reseating that boot (have several homade hookers I've make, just can't seem to get the back side of boot to hook.)

I went out last night and reshaped end of my hooker to make bottom part of J shape shorter and tip narrower, can't say backside just popped on, but problem solved.

I fashioned a metal clothes hanger hook and then I hold the inside section of the boot in place with my fingers as I hook the outside section into place. Works every time.

I have 87 aspencade, have noticed what looks likes grease slung out around rear wheel, on the shaft this dope from vent cap? or, is it some thing more serious? Can wheel bearings get hot enough to sling-out grease?
#19 06-13-2010, 09:09 AM,
If it is from the vent cap on the final drive it would be heavy oil like 80 or 90 weight. Was the rear wheel off lately? If so maybe someone over greased the rear splines.

Are you using the recomended Honda moly 60 paste to lube the splines? It should be black instead of grey.

I guarantee you 100.00.00% that the grey paste is Honda Moly 60. The colour of the paste has recently changed, I guess.

The Honda Brand Moly 60 was purchased from BikeBandit and came in authentic Honda packaging.

As long as it's the right stuff, very important not to use regular grease. Where did you get the drive flange, it looks new?

I regrease every two years but you must use Honda Molly-60 paste, anything else will not protect your splines. You can get it a most Honda dealers.

When the bike was designed, it came with tires that one was lucky to get 10,000 k let alone miles, so each time the tire was changed the rear end would be greased, usually two years sometimes one for some people.
Now we have tires that are doing more than twice that mileage, this means the rear end is not getting greased enough.

I do mine every second winter or if I feel I have done enough miles once a year.
The only stupid questions are the one's that are not asked.

his is what I have been using to do my spline lubing for years, and mine look new on my '85 Aspencade.

I use it on the rear splines and the drive shaft / U-joint splines both ...
... as well as on the '97 1500 trike front U joint splines. I use it a few other places as well, including front sheel bearings in my Fords. I even use it as a slide and barrel lube on my Sig pistols. I get it at NAPA.

Molybdenum disulfide is something I have been using for 30-40 years, I used to buy it as Crane Cams Assembly Lube.

Very informative thread; I have a question? I "think" I read somewhere (wish I could remember where) that the '87 had helical cut gears to address the complaints of gear whine. Does anyone know about this? Or, is this a dream I had? :mrgreen:

If push comes to shove and you have bad diff. or wheel inner bearings ect. then you can install the rear wheel, spider gear, diff. and brake rotor along with the caliper mount from a 1500 on the 1200 bike, the only mods are drilling the four bolt holes larger in the rear end of the drive shaft tube for the larger bolts on the 1500 diff. to pass through, and also grinding down the corner of the caliper mount to fit into the swing arm mount of the 1200.

1500 rear ends are readily available from many of the trike conversion shops for very little money.

happened to read a post on one of the sites about Loctite # 51048 that has 65% moly base,8oz
won an auction on ebay recently and just rec'd yesterday, presently on ebay but this is not the one i got
(this is probably higher than in store) nope most places on internet $30 +
<!-- m --><a class="postlink" href=""> ... 588662f7ae</a><!-- m -->

first thing i notice is that its consistency is about twice what honda moly 60 is,which if that's the standard this would have to stick better than the honda stuff,and if it has a higher percentage would have to be better than the honda,this stuff is about like glue

3 tubs of this stuff is probably 3X a liftime supply,plus i still have 80% of a tube of Moly 60

is it better 60k in progress :d
