My trailer needs some new tyres, but I don’t know if I need tubed or tubeless. currently I have one of each!
Is there any difference in the rims?
I would normally just buy some new rims and tyres but they are odd ones with the bearings in the wheel!
the bearing face on the little end looks like its seen better days, maybe the crank mains are also worn?
the oil also looks quite contaminated with gritty looking particles?
if its below the piston rings you can drill a small hole at the top of the crack to stop if getting worse
I've done this on a few cylinders and its lasted years.
Not my preferred method, but it does seem to work.
I use Silkolene comp 2 which is synthetic
I did use Castrol power 1 which also worked well
it's also worth noting that Castrol and some other manufactures state a maximum of 50:1
