Finally won the stand off with another stuck piston in an old FERRO SPECIAL 3 HP about 1908.
Was fascinated to find that the connecting rod cap bearing was made with rectangular slots that held felt oil pads ?
Piston ring pins were at bottom of ring grooves not in center of ring as on other pinned rings I've seen ??
Were these common traits of other engs ???

Richard, the felts are new to me. The pins in the bottom of the ring seem to be common, many have them in the a notch in the gap. When I replace a pin I try to put it in the top if the bottom land is smooth. Any gap at the bottom is a compression leak, people try to keep ring gap at .004 per inch and there's a 3/16" gap at the pin.

I hav heard of the use of felt in rod end caps but I have never seen one. Another end cap oddity I once found was that the cap was attached to the rod with a pin and could flip open and presumably be ground down to fit and then be put back and then you could tighten it down with the one screw. This was a long time ago but I think the engine was a 1916 Sweet Outboard.

This is another angle shot of the above Ferro rod and cap!

The Atlantic is another of the hinged bearing cap engines. Great idea and seemed to worked well over their nearly 90 years of production. A much easier way to take up wear when you only have to mess with one side of the cap. Saves a lot of time if you only have to remove one or make up one set of shims.

Acadia also had hinged rod caps, as did Cushman engines. I restored a Hartford a few years back and it had felts in the rod cap. I have seen this used in other engines as well. Just can't remember which ones.

My two single cylinder Ferro's, 1904 and 1906, both have hinged rod end caps but do not have the felt pads. My shims have holes in them for the retainer bolt to pass thru. None of them have a crossed drilled hole in the bolt for safety wire which I think would be a nice touch. When did safety wire come into use????

Richard - does your Ferro have the cylinder offset from the centerline of the crankshaft? My 1904 does as does my 1925? four cylinder Ferro. The offset in the 1904 is about 5/16 in.; in the four cylinder it is about 3/4 in.

Cheers

Have two of the three Hp Ferro Specials both have offset cranks. Only have one apart, the other one is stuck also !

Put the nameplate in scanner. because its curved to fit cylinder shape is distorted, its more rectangular !

The 1909 Ferro "Practical Treatise" shows felt in rod cap( and to be correct will refer to these felt's with the proper terminology as " WICKS "

If your eng has no " WICKS " maybe another way to date these older engs ? whats serial number on yours or any others ??

Trying to remember ( a process thats getting more difficult than getting stuck pistons loose) other hinged rod caps, the headless Fairbanks - Morse model E is another .

I've seen the hinged rods on Caille, Detroit and Termat & Monihans. It takes a little setting up to pour bearings in them.

Beautiful work Richard. My shop is 40 degrees and so I stick around the house and wait for spring. Never got around to putting in a furnace. Guess I will have to do that one of these days.

Dick, Thanks, was out in the garage last night assembling the engine in shirt sleeves, temp at 10:30 pm about 67 deg, in day time up in high 70"s.
Planning to travel to Atlanta Georgia next week just checked weather there Low 28 to 50"s expected guess I'll find out if the ford 250 truck's heater works? certainly a neglected accessory this far south !
