crank interchange

Ok so its not a 2.0 crank jusy an early 2.4 hers a pic of the rod and main journal

[TEXAS20225]

this crank will work in a 2.0 or 2.4 with steel cage bearings on the mains the 2.4 steel cage main will NOT work in a 2.5 it too small in diameter if you look at the center main in the pix there nothing for the plastic cage to ride on it works itself back and forth till it grinds the cage away sometimes very quickly other time it takes a while but it will eventually destroy itself

Thats what I needed to know. Guess Ill just use my 2.5 oiler crank. Thanks for everyones advice

i pulled out a couple of cranks last nite, the earlier 2.4 cranks will not work, as they don't have the surface for the plastic bearing retainer to sit on. i know the later 2.4 crank had it. also pulled out a 150 crank(1.5" upper bearing) and it had the spots for the plastic bearings to sit on, but i'm unsure of the year of that crank. i took pics with my phone, i'll try to post them up later to clear up any confusion. i know other people have gotten away with running an earlier 2.4 crank but it isn't worth the chance.

here are the 2 different style main bearings you can see on the plastic(which is the later style) that there is nothing holding the needle bearing retainer from contacting the sides of the crank

Attachment 315245 here is the 150 crank you can see at the top and bottom part of the journal a large supporting area on the crankshaft flywheels that the plastic parts rides on

Attachment 315246 here is the 2.4 crank

Ya'll puttin' to much emphasis on what it came out of.....

shouldered center main will run in anything 2.0, 2.4, 2.5 (small/large OD plastic bearing)

non shouldered center main "pre fat block only" 2.0, 2,4 (metal caged, lipped race)

link doesn't work on my computer?

And what happens when you have a used crank you bought that has no bearings on it? This makes it easier for people to tell what they have. i put the pics up with my phone, i can open them with google. is anyone else having a problem opening them? unsure why the first one shows the pic, the other ones i have to click on.

[tlwjkw]

if ya buy a used crank ya better know what ta look for and not worry what it came out of 'cause tha seller just might be a bull shiiter...........

[tlwjkw]

clickin' on it shows up "invalid"....

[dwilfong]

So who has the part # for the 260 large top bearing career and bearing ?
Or a ser# for a 260 that will have it to look it up.

OK so what years and what eng have the 1.5 cap and bearing.
Thy don't specify what is what.
Could use some clarification.

[tlwjkw]

'91 ta '95 should be same.. try part number 847523 a2 for assy, 74248 for bearing.... but some older production had 'em also...
