I searched the forum and consulted the manual but did not find a clear answer.
I'm putting new rings (Hastings) onto a set cast iron pistons. When pulling the new rings out of the box I failed to observe which rings came out slots 1 & 2. I know which rings go on the bottom of the piston but I'm confused concerning the top two rings. One set of rings has the bevel and dot on the same side and the other set has the bevel and dot opposite of each other.
Which is the top ring and which is the second ring? Thanks...
Since your asking the question there must not have been an explanation sheet in the ring box or wrappings.
I'm thinking that the set of rings I used in my 21 Touring had a explanation sheet with it. I do remember referring to it a few times.
You might find some information on the Hastings website.
The Hastings ring literature states to follow the numbered slots in the box but I took the rings out before reading that. There's no clear info on their website either.
Call whoever you ordered them from and ask them to open one of their boxes and tell you which rings are which.
Try this Tim.
Reading Hasting's ring website:
Top ring: has the dot and bevel on same side, which is the top (install facing up towards top of piston
Second ring: has the dot on the top (install w/dot towards top of piston) and bevel will be down, towards bottom of piston.
Oil Rings: self explanitory.
I found this at: https://www.hastingspistonrings.com/tech-tips-faqs/which-is-the-top-ring
Thanks much Les! I looked all over their site but could not find this info.
Stagger the openings so that the compression and oil will not go right through. Don't put the openings right over the wrist pin either.
