when i put my crank in the cases with the main bearings installed in the cases. the crank will move side to side in the cases when i push on one side of the crank and then on the other. Any on else have this problem? Do i have the right bearings?

 

[brendanfw14]

that doesn't sound to good. my 80 engine that I just put new bearings in doesn't do that. uh-oh

 

[Bad Ass Honda 250r]

well im thinking i might have the wrong mains in. because when i bought the bearings. they said for hotrods cranks only on the package.

 

[brendanfw14]

call em up

Their should never be lateral play in a crankshaft.

 

[Bad Ass Honda 250r]

what should i do?

 

[brendanfw14]

call hotrods

 

[tughill283]

do you have stock bearings to compare them with?

 

[Bad Ass Honda 250r]

no i dont. i was thinking about going to bikebandit.com and buying some oem bearings and seeing if that would fix the problem. OR just getting the part numbers and getting some from napa.

 

[tughill283]

i go with napa for wheel bearings and such but id feel better off with the oems when it comes to the crank.

 

[Bad Ass Honda 250r]

do you have any for sale?

 

[tughill283]

i got a whole extra oem 86 crank but its used.youd be better with new bearings from honda.

 

[Bad Ass Honda 250r]

how much do you want for the crank?

 

[Mert]

side to side play isnt bad as long as it isn't too much, vertical play is what you should be worried about, any vertical play at all and your screwed

 

[awames76]

is the play that u are talking about at the main bearings and case?

I think he's talking about where the rod meets between the 2 sides of the crank, mine had some minor play in there when I re-assembled it, I didn't put it together the first time, but it runs great, and I've heard of this before, but someone correct me if I'm wrong.

actually im talking about the crank between the cases.

Yeah....their should be VERY little if any play there. Especially on a machine with a bell style flywheel. You can have lateral Rod play and that is normal, but the tolerance for crankshaft play is like only .004 of an inch on those.

 

[tughill283]

ill take a look at the crank tonight,it came with my 250r when i got it along with some other stuff,i never really looked at it close.i let you know what shape its in.

 

[Bad Ass Honda 250r]

alright that would be great.
