Hi All:
Is there an alternative to those &^$%^&(^& Fox wrist pin circlips? Is there a source for brass or nylon pads?

You have to use the FOX clips, however if you put the piston in a large clear baggie when installing, they stay there instead of flying all over the room when they spring off. that technique will save you a lot of time and trouble, if you use pads you will need to turn them your self

Hi Randy:
Thanks for the reply.
I have tried the plastic bag, thumb nails, finger nails, hemostats, tweezers etc.etc, and still can not get the last one to fit into the groove. I am down to my last one and Fox has no more!
I have a collection of Fox p&c and wrist pins. Some used circlips and some used brass pads. I would like to get all of these parts used in engines but the circlips drive me wild! I have been told just to work them in with your thumb nail and fingernail. Easy enough! Lol I had an engine "expert" have me take the parts to him and he was going to demonstrate how easy it was to install them. After awhile, he gave up! Lol
Stay well my friend,

Hi Frank
I have set 1000s of the circlips in place on all types of motors, it is easy when you do that many, frustrating if you only have done a few, at least the clear baggy trick keeps them for you so you do not lose them.
Try a wooden icecream stick , or epoxy mixing stick, they work pretty well pushing them into place, then you can use a large T-pin to set the clip in the groove

It's critical to get the grooves clean of carbon and gunk. I use a hemostat, but it has a very small tip. I've made my own for ST's from solid lines, and never had a problem, either with them, or stock ones. I don't recall if any Fox I've had used circlips or not, tho. H^^ Steve

We were out one day at a site with heavily degraded blacktop, and either Ted or Dave sproinged out one of the circlips in a 46VF AAC, into the mix of very rough pavement and loose gravel. I ended up *finding the thing* in what amounts to a pile of pea gravel! That was when I could still focus at close distances - not much chance of a repeat given their current state.
The carpet in my bedroom/workshop is another story. Its probably distorting the local magnetic fiel with all the random bits embedded in it!

Hi All:
Thanks for the replies.
Randy: perhaps I just gave up too soon! Lol
Yes, there is nothing better than experience to learn a skill!

i made a tool by grinding down the end of a pair of small Snap On needle nose pliers. ( and use the Baggy.
if you are going to use the wrist pin end pads ,make sure that the wrist pin dosent go past any of the transfer ports or garenteed it will end up in one of the ports
once they went to schnurly stuff they went to clips, the reason that OS and most of the Chinese engines have thier sleeve turned at about a 45 deg angle is so the pads can run on a solid wall

Make a new piston with a tighter gudgeon pin hole and use a press fit pin?

I found a small coil spring with the same wire diameter and OD of the Fox circlips.
You can cut as many as you need.

Hi Robert:
Tell us more about the coil spring you found. Where would one find one?

Oh I can relate to those dang cir-clips, granted that this is my First fox .35 I've lost quite a few on other engines. It's an art getting those suckers in there and I still have yet to master it lol. I use a baggie and a brass rod ground down to a point and along with my finger I get one edge of the clip in the hole and use the point to walk the rest of it in then I poke around the inside of the clip to make sure it's seated in the groove.

Here are the clips I made from springs.
The small one is .015 wire, the large one .019.
They were made from some springs I found in an miniature spring assortment box I bought many years ago.
As mentioned, you can also make the clips from music wire.
Just measure the wire diameter of the Fox clips and wind a few turns on a piece of rod.
Then, cut off a few and bend the holding tab.
Works for me.
