cb360 fork oil

[jmemmert]

how much does each leg get? I finally put new seals in mine and polished them up, but need to put the oil in still.


I am planning on going a little thicker than atf to help stiffen things up too.

What does the manual say about volume?

IMHO, ATF has no place in forks. Try a modern suspension oil. In those old forks I'd start with 20Wt fork oil and see how that works

According to Hoyle (the shop manual), There are two different measurements one for just changing oil and one for when you pull the forks apart and rebuild them.

The first is 134-140cc or 4.6-4.7 ozs. The second is 160-165 cc (5.4-5.6 ozs). Both times it states using Premium Quality ATF.

It's good enough for them it's good enough for me. Though, YMMV.

If you have the bike, get the manual, its available all over online for free if you know where to look. It will answer most if not all of your ??'s

thanks guys, I'll see what 20 does for me.

What is the correct amount; 140cc or 165cc? Fully disassembled and cleaned, filled to the 140cc per the manual but how do you know this is enough or if you go with 165cc how do you know it's too much???

140 if refilling, 165 if the forks have been taken apart and COMPLETLY drained and are dry. And not givin ya shit, but I bet your manual is 40 years old. At least the info in it is. They make fork specific oil for a reason. And no bikes today use ATF nor do any shops, so use the fluid made for the job. You only have to do it every so often, so spend the extra couple bucks for the proper product.

+1. They didn't have a dedicated fork oil back in the day, so they recommended atf.

And I've never disagreed with Teazer til now. I would start with 15w oil.

20wt is too thick for the springs and forks will pack down.
10w should be plenty, oil is to provide damping not 'spring' particularly as there is virtually no compression damping in fork

Thanks all....and BTW, I'm doing fork oil, not ATF. I did put in 15w so past the amount, I should be good! Thanks again.
