How F'd is my crank

[ShadowFlier]

I already know the answer but is this crank savable or not? I was going to start putting pistons back in when I noticed this. This build is turning into a big headache.

You better check the bleed fittings at the top and bottom of the front half too...but that thing is a lamp.

Q: "How F'd is my crank (https://www.screamandfly.com/showthread.php?348842-How-F-d-is-my-crank) ?"
A: "Proper F'd"
(A reference to a recurring line in the hilarious Guy Ritchie movie "Snatch" lol).

[Whaaaaat]

For those that know, I don't. Expense aside could it be saved? Spray welded then reground? Or some other method, or would the heat of welding ruin the hardening?

[roadkill636]

Even if spray welded. Would that still be a week point for the harmonics of the flywheel to give it someplace to break at?

[coffeeguy]

If it has a 1.5 dial could a reputable CRA k rebuilder turn it to 1.375 ( large beari g to small)?

[ChrisCarsonMarine]

Find another crank.

[TEXAS20225]

x2 it has a special plating done by Mercury

[FUJIMO]

this is the bottom line with 2 stroke cranks... they have to be perfect. the end.

[roadkill636]

Call BLACKBIRD . he'll buy it

[Merc 2.5]

Ask David Eden if he can fix it. If he says no, it is a no.

That is (supposedly) the one place- Marine Crankshaft in CA- repairing them "properly": http://www.marinecrankshaftinc.com/outboard.html

[Dave S]

Why bother fixing.....A good used one is $200....end of story.....I don't see any Lancia V6 cranks as lamps....They were art work....... 5cly audi?

[patchesII]

You’d be 500 into it for Marine Crankshaft to fix and it’ll still be a repaired crank. Just find another one. That one is junk

[Merc 2.5]

I have a crank that 1 journal has damage but its barely enuff to catch finger nail , I figured its junk , but r u sayin if it's a very minor nick or sumthin it could possibly b fixed? Just curious,

[Merc 2.5]

Hey dave. u got any 2.5 top guide rods? Fishin rods?

[Dave S]

Merc 2.5.....a small nick is ok.... for a fissing or hand granade.....If ya use the old Big rods it will hold up case's them rods are close to bullet proof.....but stick a piston and they will beat a block to bits.....Yes.I have rods........Sorry I never got back to you about carbs......that happens in Daves world........

[tux974]

Forget fixing! Find another crank and make that one a nice lamp with custom bearing surface!......:thumbsup:
Also as stated, check your oiling check valves are working properly and clean.

[TEXAS20225]

x2 Tony i have a clear hose i put on the bottom to top bearing oiling hose to see if its oiling then replace it with new stuff, rods are just as dangerous if that cap aint perfect i never used it i ve seen many rod bearings that cage hung on the mismatch and bearing started skidding ruining crank and soon the rest of the assembly

[Dave S]

I have a crank if ya want.... u pay shippin.... to 2.5 merc.... same as I have rods just PM me ya # street adds...good lukanhappynewyears......and ck the flwhell... top brng.....something ate the bearing.... pre 1982s bulestrip....have poor contact area... on the lower seals.. JUSTWHATIKNOW....I know Dave S. is a ****ty spella...Hick......

[tux974]

Amen Bobby! I use yellow Tygon with small tie wraps on all bleed. I also always replace the top & bottom bearing plus cap seals top& bottom no matter how good they may look.

[phillnjack]

That can be done ..... get it to a crank specialists .
But it all depends on the cost v a good used one.?
in the states you have masses of good used stuff so its more than likely a lot cheaper to replace.
