Front maintenance (fork OH + stem lubrication) + bottom polishing Sunstar premium disk & RMZ pad service kit etc. This is what was requested.
The bottom case, which had some corrosion progressing, came out like this. It turned out really clean. Sorry we don’t have a before photo.
We spray urethane clear coat so the corrosion won’t progress.
And the next day. The inner tubes on both sides had no issues.
The fork oil dirt is pretty moderate.
When we can clean things up nicely and reassemble them, it feels good on our end too.
The standard SKF. Mysteriously, it seems strong against leaks. There was a vehicle before where nothing would stop the leak…
New ones × 2 didn’t work. Didn’t work with Ariete. Didn’t work with a repurposed double spring oil seal. Didn’t work even when we disassembled the oil seal spring and shortened the overall length to tighten it more. Finally it stopped leaking with SKF, so I kind of became a believer from that experience.
When new it’s definitely low friction, but after some use it’s actually pretty normal. You can really tell the difference when you stroke a used one that’s been removed.
I’m not sure if it’s the secret, but we load fork oil inside the lip before assembly. We can’t recommend grease sealing because it deteriorates and gets crumbly.
The oil we use is 100% synthetic Newtech. Blending is also possible. The blend chart includes kinematic viscosity index, which is helpful.
Vacuum evacuation is really fast. We can do different work while that’s running, which saves time.
In the meantime, let’s lubricate the stem bearing.
There’s still plenty left. This NC100 grease is really high-trust grease.
With good amounts on both top and bottom, we’re set for a while.
Since there’s no before photo, only the owner would know… maybe? It’s subtly clean and looks great.
The hugely popular neo-classic brake disk was requested.
It tightens up right away and feels really good. Currently waiting for the pads.
The bracket we made the other day had a mistake… the nav was forward and the bracket was forward—we mixed them up. Well, if the usual way is fine, that’s easy. Takes a few minutes to bend.
Weld it, polish it, and done.
That’s how it turned out. I don’t like Nissin radials because the tank sits higher due to the removal relationship.
Tomorrow we’ll wash the caliper, swap the pads, and it’s done!
