Ironhead Hastings rings confusion.....

[MN Mailman]

On the second compression, I've got both a dot and an inside bevel........but the bevel is on the bottom ring face.

I.e. the dot is on the top of the ring, the bevel is on the bottom............so, both are supposed to be facing the piston top, but only one can.

Anyone seen this before with Hastings ?

Wish I could help you!! But I would be just as stuck.

It is the bevel that counts. Facing the incorrect way it passes a lot of oil.

2nd ring bevel side down
top ring bevel side up

I do not have a lot of experience installing rings. I have a difficult time deciding if i am seeing a dot or just some random mark; the same deciding if there is a bevel or if it just looks that way to my old eyes.

But one time i got them wrong and i was using a quart of oil every 500 to 600 miles.

Dot up....bevel down....it's a reverse torsional ring

the subject has come up here before. not specifically with hasting's,but with several brand's. my s&s piston rings have both bevel's up. mick had mentioned the brand that he is running,were both direction's. [i,hope i,recalled this ,correctly]

I was thinking of that; like a scraper on the wall, and just found some good diagrams showing same on their site.

Thanks Mick.

Oops, i was reading the Wiseco instruction sheet. Presumably it is the same for the Hastings?

[MN Mailman]

Then again, with an inside bevel, it won't contact the wall anyway

Hastings site says always put the dot up, when present.

I have a set of Hastings in the shed, if you can't figger it let me know and I will see if the instructions are still with them.

Cheers

Seems to be different Mick; Hastings says always have dot up, if one is present.

Inside bevel only applies (it seems) if there is no dot.

Dot trumps all it would appear, with Hastings.
