Crankshaft shopping

Here on this website, new crankshafts are $683. I have
done some searching, and can find them for less than $500.
I may go that route instead of grinding the old one...for just
a little bit more money, doesn't that seem like a better
idea? If I need to lay out that kind of dough, plus all the
work I'd rather have it last.
Also, if I do get a new crank, do need I need all new
bearings-rod and main bearings? If I can get this done in
the next couple weeks, I can sell my last cutting of hay to
help pay for it.

Hey Bern, your description of taking off the crank sounds
just like "drop the oil pan"...I'm kinda leery right now:). My
manual isn't to descriptive on how its done, but I think I
can follow yours well enough
 
Only potential problem I can see with a new crank is that the balancer gears *may* have to be replaced as well. Ford updated the balancer and crank drive gears for durability reasons, which might present a mis-match issue.

It's possible that an aftermarket crank uses the old style gear, in which case you may be OK. I'm going off of memory here, maybe Rod or Rick B can help, but I think the old gears were 1/2" wide, and the new ones were 9/16"? Or am I confusing those numbers with head bolt diameters?

If you were to get a new crank, you would be a fool to use the old bearings. It would be like buying a brand new pair of shoes and wearing them with dirty socks.

If you have the front end off already, removing the engine block will be fairly tame by comparison.
 
Hi been following your story for a while. sounds like you got the brown end of the stick with this tractor having a re built motor!.There are some real honest people out there L.O.L.

Hopefully the new crank will be good quality there are a few made in China junk ones out there. Maybe someone here can recommend one at a sensible price.
I trust my motor shop guys to supply me with good quality sensible priced ones, when needed.

Yes you do need to change all the bearings, you already got a half a@#ed motor now. the bearings are probably worn if not destroyed. you might have over sized bearings if the cranks already ground, from standard that won't fit the new crank.
I would probably check the oil pump real good for wear to. No point in putting crank / bearings, other new parts in if the hearts not gonna outlive the patient. Low oil pressure will kill your new bearings pretty quick.

Well, lookeee what I found...

I can't help on the balancer gears... but I get indigestion thinking about some aftermarket parts that go round and round. I'd probably call Fawcett's and get a used one first.
I don't know where these folks get their cranks and engine parts but if A&I was involved I'd steer a wide circle around it.
A new crank might well be a question for his local machinist...

I have no input on the old/new style balancer gears. I too, would be VERY careful about sourcing an aftermarket crank, and probably would lean heavily towards a used crank from a reputable salvage yard such as Fawcett's or Wenger's even if it cost the same. If these guys sell you something that ends up not being up to snuff, they have a history of making things right.
 
I have a Ford 600 that I use for tractor pulling. Originally it had the 134 motor. I decided I wanted more hp so I thought, from a good friend, that I could punch out the block to 172. After disassembling the engine, having the block hot dipped and checked for cracks the machine shop said there wasn't enough meat to do what I wanted. Long story short, I ended up buying a re-maned 172 short block. I have the block and crank along with the cam just sitting there in the corner. Make me a fair offer and it's yours [or anyone else if someone needs any of these parts.]

johnB - I guess you haven't been following this saga through the multiple threads. This is for a 5000 diesel, not a hundred series.
