Stainless Steel Fasteners

crosleyhotrod 1/2/02 2:49 am

I am rebuilding the two engines I have ---one chassis.... and I have already bead blasted, primed and painted all the pieces. My question is to the use of stainless steel nuts and bolts for things like the water jackets, oil pan, etc. Will these be the correct "grade"?? or should I use regular zinc coated grade 5 or grade 8 fasteners???

Of course these will not be "Correct". But I use them on everything because they will not corrode. Better than was used back then. Have rebuilt two engines using SS on pan & water jackets. No problems. Think they are stronger than original so be sure not to strip threads in alum. Good luck. And SS bolts are more purty. HA HA Larry

In the second photo, the engine pictured was typical of the time...bored out 100 over to a c.i.d. of 48 c.i. Stromberg model 97 2bbl carb. Notice the modified oil pan that had water lines running thru it to cool the oil(my dad's invention) and that the motor is flywheel forward. The dynamometer was homemade using a fish weighing scale and a torque converter from a Buick dynoflow transmission stalling it by running water thru it some formula my dad worked out he could figure the h.p. output...on gasoline about 60 h.p. on racing fuel..about 75 h.p.@ 9000r.p.m. The torque he could read from the scale VIPER

Unless I find more the first of the finished photos, the boat in the background is a Y class Crosley powered dad broke 100mph in that boat. The pics really don't do justice to the finished product...It was quite a stunning little car...pretty quick too! My dad wouldn't put a wild cam in it for me but he did other things to it. a 2bbl carb, tuned exhaust,no muffler,wico mag, and a balanced steel crank. It would turn upwards of 6000rpm when stock crosleys came apart at 4500 or so(due in part to weak cast iron cranks and cast iron pressure plates and springs coming apart). He fitted an international harvester tractor clutch with a reduced diameter flywheel and bell housing which mean't I could really smoke the tires...I remember a buddy of mine had a 47 ford flathead that couldn' catch me in a drag...That was saying something as the transmission was,as you all know, a crashbox. I became very good at double clutching...OOPS! I babble.....This club and seeing all the photos sure does bring on waves of memories... Later... Viper

Hmmmmmm....Nardi....Webber....Nardi rings a bell...only Webber I remember was carb people...I know that 100 over bore was no problem for the little 4 gave you 48 c.i. about 750c.c.'s...and yes Aero rings true...built refrigeration units and used the crosley p/p... were used on semi trailers. they were governed at about 5000 revs if memory serves(hah!). Do not recall any wrist pin problems and my dad had one engine design that turned better that 11,000. He named it the sidewinder...had 2 2bbl on either side of the block and each feeding two cylinders. As I recall, stock rods and pins, along with his pistons were used...he never stroked one as I can remember, wanted to keep the piston travel to a minimum...though he did destroke one or more and over bored to 100 over...Probably brought it down to stock c.i.'s...and now that I'm thinking about it he did manage to 2 cycle one...but couldn't control the revs(b4 electronics)..that was destroked and bored...I remember that the rpm's were off the scale, and NOTHING in the bottom end was stock crosley...and don't ask me about valving...all I remember is that It sounded like a zillion bees... The sidewinder was probably his best all around design..and he built more than a few...had one in his little hotshot and what a redlight to redlight zinger THAT was...When he died in 81, my brother and I sold off all the crosley parts and motors he had(hey...who knew there would be Crosleys around as collectibles)..He had one sidewinder left and his attorney bought it from us. He lives in Miami, has(then) a Crosley that had been shortened and used it in parades. Any body from the Miami area may remember seeing it...It was quite a neat little car...could turn around on a dime. Anyway, he was going to use the engine in a hotshot that he had... Ahh, I babble again...Oh, as to your question about driveline problems,,,just gearboxes, when I tried speedshifting(usually after a few beers)...I had lots of extra pieces of tranny parts. Yes, and stock clutches when I would rev too high..but after I had the tractor clutch, no problemo... TW

Webber--made clutches, flywheels for various applications [flathead fords and others]I think is where they started and and expanded out to other areas; speed parts for smaller sport car classes in the fifties when it became real popular. The webber crank is listed "I think" in the Braje catalog.Lots of crosleys lost their drive trains to class H sports cars...I said aero engine but meant the military experimental for aviation that you had talked some on a previous message. Your father was certainly into his engines, sounds like he put a lot of time and effort into development. Ever think of writing like a biography {spellin?] of him and his engine work? Would be nice if you still had some notes and/or drawings to show his designs. At least I would find it interesting! Seb

Concerning my dad, The only engineering notes were in his head...believed if he wrote them down they could be stolen. Would not even consider patents...something about the corrupt govt. And yes many drivelines were lost to "H" production cars(except for trannys)...A Fiat tranny(what model I don't know) was a popularconversion for the H car...4 spd, all synchro...Back to drawings...Powell Crosley visited dad once I know of, maybe more...Wanted dad to work for him as I recall...don't know in what capacity. You gotta remember I was only about 9-10 at the time...After parents got divorced, actually became closer till I went in service..then we drifted apart( me in Jacksonville and the world, him in Miami) But drove my first car at 12(a crosley) drove my first boat at 14 and my first H car at 16. If I hadn't gone into the service, who knows...You would probably have more luck obtaining a hardened cast iron crank from an old aero motor than trying to obtain an a/c crank... Has anyone tried the local airport mech for bearings? Last week someone here was looking for bearings.... Later guys Viper

Has anyone put together an interchange list for the engine. ( I now there is some information on the CAC web site but it seems a bit dated) Maybe a small book that would describe the different versions of the engine in detail. Has any one compiled/published anything like a technical history of the evolution of the Crosley four....It sounds as if the Crosley engine had more lives than the average cat. How long was the engine in production -in one form or another? 1940's thru 1980's?? 1942- military - 1946 Crosley car and other use/ generators/refrigeration units - Homelite boat motor in the 1970's? Was the Homelite version the last produced. Is it possible that some where in the third world/ South America / Africa / India the engine is still being produced? I Know this isn't likely but I have run into surprises before. Ron in Indy more motor questions tin blocks

Ron, You said: "Has anyone put together an interchange list for the engine. ( I now there is some information on the CAC web site but it seems a bit dated) Maybe a small book that would describe the different versions of the engine in detail." No book has been published as far as I know. The interchange list was put together on the web site from many years of Crosley Club Quarterlies. Some of the info is dated but it is what we have. I keep the web site and will gladly update and add new info it is sent to me. Jim...
