Just opened a pack of fairly recent Hastings rings. No instructions as to which way up they should be fitted. Both the first and second compression rings appear to have a slight taper to the inside of the ring but no stamped dots on the top. I have a set of older instructions and they show them installed with the taper down but they also show a stamped dot. Anyone installed a recent set of these?

Same here. Just opened two recently purchased Hastings ring sets that I haven't yet used and neither had instructions as I've previously seen with Hastings sets. Just the paper sleeve with 1, 2 & 3 marking the different pairs. The dot was there on all rings, often faint but shows up with a magnifying glass. Not the same packaging as the last pair I actually installed.

Edit.

Correct Compression Ring Installation: Piston Ring Assembly Tip – Hastings Piston Rings

www.hastingspistonrings.com www.hastingspistonrings.com
Rings having a “pip” mark or dot on the side of the ring must always be installed with the “pip” mark or dot toward the top of the piston.
There are two styles of torsional rings with inside bevels, top inside bevel and bottom inside bevel. Always check for the dot.
 
I did a post about a year ago, Hastings has stopped making several rings, mine was a 65 BSA. Leave me clarify. They make the diameter you need but maybe not for a, in my case a BSA. A generic ring, no top ID. They wouldn't seat and replaced them with a set made in England from Klempf's. The oil ring for a Norton should be three pieces depending on year not cast one pc
 
l got out a really good magnifier and found the dots. They were all counterclockwise of the ring gap about an inch when correct side up. Would it have killed them to make the mark a little more visible.
 
Same problem yesterday. I assumed it would be the bevel side up but called two very knowledgeable people including the place that sold them, Coventry. The packaging seems generic so not entirely trustworthy. Coventry agreed with me that the bevel side goes up even though there is no mark. so I installed them that way. Will see next week when I start up the 850.
 
Once you are comfortable with the correct orientation and position of each ring make sure you check the end gap. The correct end gap range is not a secret; I am confident that a search on this forum will give you plenty of data to distill . I have yet to find a set of rings that didn't need some reduction in circumference to fit the bore correctly.

Best.
 
Hastings used to show pics of their various ring styles and orientation with their ring sets. I guess they no longer do that. Did you check their internet site? Maybe, like other manufacturers nowadays they expect :mad: folks to get instructions via the internet! Oh well, maybe that's better than a 20 page book in 15 languages with every ring set...:)

Still made in Hastings, MI? Or manufacturing outsourced to China?

Just fitted a set from Mapcycle to my 750, box has USA on it, even box says printed in USA.
was difficult to see dots on top of rings, like Htown once I used a bright light and magnifier I could see them. Bevel up.
 
Again - based on memory - the pictures that used to accompany Hastings instructions showed a dot AND a pic showing the direction the bevel or step was oriented. IOW, you could determine the orientation whether the dot was visible or not. Are you saying that they come with NO reference at all about direction, not even a statement to check an internet site?

This is what came with mine, no instructions just a QR code on the inside packet that opens up Hastings website but states page cannot be found. Old stock maybe? Hastings rings installation instructions

Hastings Rings

I'm rebuilding a 1972 750 Commando and planned to install the top end today. When I opened my new set of Hastings rings (Hastings number 7007), I was surprised to find 4 rings in the top slot of the envelope, none in the middle slot, and the oil rings in the third. All four compression rings...

No instructions. Guess they mean for you to go to their website. Once you find a dot on one of the rings you will know where to look on the others. They are there but faint. Based on this John Healy reference mine have the bevel edge on the dot side. Both dot and bevel edge will go towards top of piston.

Don't they (JCC) still have a problem? Looks like both versions of the envelope recommend bevel down for the second ring?

I found that if you wipe some oil, penatrant or any other liquid on the rings then the dot will be easier to see. That and a magnifying glass of course.

Like Htown said; " Would it have killed them to make the mark a little more visible?"
