width big end 18.8mm
big end Id 37mm
pin Od 30mm
pin length 60.90mm
small end Id 18mm
center to center 124.67 mm

these are the best dimensions that i can get off the old rod. failing which i have a 1985 husky wr250 liquid cooled motor which should fit but i would like to keep it standard. I have a number of old Husky's and believe the next step in the development for my collection is the berg

any help would be appreciated
thanks Chris

Re: Conrod Drawings

Mr Bushmecanic, so far as I can see the dimensions for 450 and 470 rods are near identical. I did notice however that the bigend bore was machined off center by 0.5mm, as you can see from the photo, there is a 1mm difference in wall thickness between the two sides. Was this done intentional or do you think it was a machining error? I suppose if the hole was machined right in the center, there might be a 0.5mm difference in the center to center measurement.

Other slight differance is the location of the lubrication hole for the smallend, 450 right on top underneath the piston, and 470 on the bottom an toward the side, I suppose then the hole must face toward the oil jet in the engine casing.

In the photo I have the 470 rod lying on top a 450 rod, and annother 450 rod on the left.

Re: Conrod Drawings

Some measurements from the conrods I have. I've just added the values onto your drawing, Bushmechanic.
I hope these are helpful.

Re: Conrod Drawings

02 644



after that its 1mm longer to bring the piston up

according to the DOC the 02 501 rod length is 123 ... may not be correct

so this one http://husaberg.org/gallery/d/58344-2/550+rod.pdf

the 400 length is reported to be 120mm so identical to the other 2 linked above but 120 long
Thanks from Jim o

Re: Conrod Drawings

most are done

if anyone finds an error in the dimensions let me know it is relatively easy to change them.

the rod length table in the DOC is still wrong for the pre 09 450, has been since i can remember -- about 2006 ish?

Here is the dimension of the crank offset to centreline of the
cylinder bore, 6.331mm.

And the height from the crank axis to the deck/head gasket face of the block 200.179mm.

This is for the 628cc motor.

Any calculations for rod lengths will of coarse have to take into account that
the rod is on an angle at TDC and the compression height of the piston being
used.
