Yes it's going slowly:

I am waiting the SKF ball bearings for the wheels and the tools to remove the old one properly. One from the front wheel is out of order, and without seals ?

The front tire is in place, the target is to have both wheels in place by end of the week.

I've been using sealed bearings in motorbike wheels for many years so don't usually fit new seals but do find that with some wheels it is helpful to have something to hold the spacer in position while the axle is being inserted. If the old seal is beyond reuse on a wheel like that, I usually make a rubber disc that fits where the seal would normally go, to hold the spacer in place.

PS your wheel looks excellent

The good news is the grease was fresh, bearing was easy to remove 🤨...

They need to be tight in the wheel and "loose" in the shaft, I will see with the new one expected for this week-end. Just remember how old is the bike 😬.

One needs to be replaced the other one seems ok but will be replaced too.

Remember, I said: "The good news is the grease was fresh, bearing was easy to remove 🤨..."

One rear bearing is not tight as it must be in the drum. I will ad some retaining compound to prevent any rotation.

Front wheel is done 🧐...

I could start to install the front fender, speedo and brake hardware 🤨.

I have in my shelves an old speedo  bought for a previous project but never used: I will use it ☺️.

Rear wheel is done 😅, we will see if the bearing repair is working when running.

I made some adjustments (grinding) to remove swingarm play 😏, you could see that you have  a dirt bike not a race bike 🤫.

Next step: back fender and rear tail light...

Chain guard in place, time to adjust the fenders: I want to make one with 2 parts.

The frame had a long life before me. I will need to bend some supports 😏 to have have all ( seat, fender, gas tank,...) in the same line...
