Cases for stroker

[haggis]

In the process of building a 5mm stroker engine and have the chance to buy a set of ported 62t cases at a very good price. Thing is they have been machined for a 6mm stroker crank, is this ok for a 5mm or not?

 

[Big Kahuna]

yes, it would have been clearanced for the 6mm, would not effect the 5mm

 

[#ZERO]

What brand 5mm stroker do you have?

 

[haggis]

its an ada cylinder and head.

 

[DangerBoy]

I think he meant what brand crank,
some were larger than others

 

[haggis]

Oh! Dont have a crank yet, was thinking i would buy a new one from crankworks or if anyone can recommend another manufacture would be good.

 

[DangerBoy]

I know the RAD cranks were larger and required a bit more clearance than others, Ive never used one from crankworks so I cant help there.
worst case you would need to have the cases re-machined, but you would have to do that if you started fresh, and there is a very good chance that the crank will fit, so if the price is right Id get the cases

Cool thanks for replys guys.

 

[waxhead]

if the rad cranks are larger then the crankworks one
i would not be suprised if you can fit the 5mm crankworks in the stock cases

 

[3rid]

wax, the 5mm crankworks needs clearance, won't fit in stock case.
The rad crank fits with minor grinding ... as it uses oem rods.

 

[waxhead]

yeah thats what i was thinming there was only minior on the rad and the crankworks is smaller you may have got away with it

Buti havent fitted a crankworks i have no idea

But it would seem you need to to do huh

Crankworks uses Hot Rods on their 5mm strokers and the Hot Rod are thicker than OEM rod and with need to be clearance'd to fit.
My guess it should clear a 5mm if cut for a 6mm. But may need some touching up...

Thanks again for the replys, supertune when you say that it may need some touching up, what exactly do you mean? possibly have to remove more material or replace using epoxy?
