Hi all,

Lockdown has been a good excuse to get back to scooters after a *long* absence. I've bought a 2013 PX150 that had about 9,500 miles on it.

I've been trying to work out whether a wobbly front-end was down to me getting old, or something else. Ego persuaded me it was probably the latter, so I decided to replace the front bearings. On stripping it down, the axle/hub look like this (the dark on the axle is far more brwon in real life):

The axle looks as though it's run with knackered bearings and I'm not sure about the mess around the speedo drive. I'd appreciate some advice as to what I really need to replace and what can simply be cleaned and greased. I've bought some bearings so far, but suspect I need more than that.


Thanks

Ian

Hey Welcome,

My front end work experience stops at brakes, cables, and the speedo drive-cog. Maybe someone else with more experience in that area can chime in...

You should definitely replace all the seals and bearings, replace the speedo gear, etc.
I just replaced all my bearings and seals on the Stella front end hub and back plate; it's not too hard, you will destroy the old ones knocking them out, make sure to use a proper-size socket or similar at a drift and not score up the seats. Heat and cold help, but I still had to hammer the new ones home. The main hub bearing can go in crooked, use a block of wood and hammer on that to get it started.

Don't use a screwdriver as a drift to remove the needle bearing in the hub (as I did), it can slip and gouge. Better to use something blunt that can reach through the main hub bearing and knock out the needle bearing from the inside race.


Is the axle just stained or is there a ridge on it that you can feel?

Having had a chance to clean it all up, the rust is cosmetic and I think the axle's OK. Looking at pictures of new stub-axles, they all seem to have a dark band at that point (some kind of heat treatment?) and there are no ridges I can feel.

Bearings going in the freezer now. Hopefully I'll be able to knock off work early enough to put it all back together this evening.

And stick the hub and back plate in the oven. I did my at 200 degrees F. Probably could have gone higher, I didn't want to burn my hands. But clean the grease off first!
