some of the latest listing pasted below for anyone still wondering WTF is the go with the "right rod" for the 450

.

This is a Japanese made aftermarket rod kit that is a direct replacement for the 450FC/FS/FE models 2004-2008.

Some 2004's have the oil feed (at the pin crank interface) 15mm inboard compared to the rest of the 450's made and the cost of the pin is a lot more. POA! please split your crank before ordering. The 450 doesn't need a little end bush which is a further saving.

================================================

400 and 470 Husaberg (2001-2003 only)

The rod kit is perfect bar being 1mm shorter! We have a 470 piston that will restore the correct squish and compression. We don't presently have one for the 400. The 470 doesn't need a little end bush which is a further saving.

The 400 needs a little end bush turned down externally to fit in the little end. We can supply this or have your original machined down if still in good condition - which they usually are NOT.

prior to this thread there was an earlier version of this listing that had markedly different text which is where the "rumor" about the rod length started

WE ALSO SUPPLY THESE KITS FOR THE 450 (2004-8) WITH THE ADDED BONUS THAT IT DOESN'T NEED A LITTLE END BUSH. *the 450 OEM rod is 1mm longer than ours so there is a small drop in compression (not such a bad thing on the 450). We can supply a 0.5mm taller piston to bring it back a little.

With factory rod kits running at £300 this is a substantial saving. The kit consists of a new big end pin, bearing and con rod. We've fitted fifty and they've been 100% reliable with not a single fault or complaint! sometimes we need a little time to have the big end pins machined.

For the 450/470, there is no need for a little end bush either - saving £35.

For the 400 a special machined little end bush must be fitted which we carry at £35.

450 2008 rod kit

It can be done in a kit and the Conrod is identical length to the stock item, some machining needs to be done on the pin. I sold my last one for about $400 Aussie Dollars and can do more of them anytime. PM me
 
Looking at the Wossner catalogue, the deck height for 450 piston is 24.3mm and 22.6mm for the 470, which gives a difference of 1.7mm. Stroke for 450 is at 57.2mm and 60.1mm for the 470, which gives a difference of 2.9mm. So the 470 bigend pin is located 1.45mm higher from the crank center(@tdc, and obviously lower @bdc).

So there should be about .25mm gap between the top of 470 piston and edge of the liner with a 119mm rod.
So, having a 120mm rod will have the 470 piston sitting .75mm above liner.

(Would this be considered the 'dome' , as Wossner catalog states a +5.6cc 'dome', but I know the 470 piston to be flat topped? FWIW, it seems the total cc for 100mm bore and .75mm stroke does in fact give about 5.7cc...)

So, if I use a 119mm rod on the 470, should I have 1mm taken off the head? Or machine the top of the casings & liner, or .5 off the head and .5 off the liner?


Or should I have paid more attention in math class?
 
I would like to to ask about this crank pin differences. But it probably does not make sense.
Because the persons which know the answer will not "sell" them.

Taffy can I somehow check if the connecting rod which I have has been bought from you?
Check without split the crank.
 
hi,

i have a 2005 husaberg fe 450 and i need a new conrod for it. I read the whole forum from the beginning, but because of my poor english and technical information i just couldnt understand. i bought a wossner 8593D piston. so there wont be any problem with a prox 04.6423 conrod ?
is that right ?
isnt it 1mm. shorter and doesnt that mean less compression than oem ?

Thanks
 
yes it is a confusing thread!

all because of some dodgy info on an ebay listing :D

its really very simple

Pro X 03.6423 rod is the same length as oem 450

wossner 8593 is the same as the oem 450 piston

you will need to check that the oil holes in the big end pin allow oil to flow to the big end bearing,

I used a prox KTM 35mm pin in my bike, needed a tiny bit of grinding to make sure the oil still made its way to the bearing ... can't be too hard for this kit either
 
It seems a lot of threads pop up about rods, why doesn't someone send a few hard to get husaburg rods to Carrillo to be made. Stronger and cheaper then OEM, they quoted me $378 for a single bespoke rod.

All oil passages are clear so it probably had to be bought from you.

yes that is probably my rod kit. I can't say for certain but what you see there is the technique that we would use to repair the pin.

a lot of work goes into each pin and luckily I get 5 done every time and this eases the costs.

the so called 'dodgy info' is infact from info supplied by members here initially before I'd had an engine down myself.

there's always some arsehole wise after the event.

thanks for the reply
i ordered the prox 03.6423 today from amazon and i will check on my 05 fe 450 if it is working or not next week.
i also mailed carillo and they said that they hadnt made such a part so, they wanted me to send them the oem part. six weeks of time and 319 $ was what they wanted. but,
as you can see in the diagram the conrod is made of five elements. carillo said that "The only component we make and can supply out of the five would be the connecting rod". so, prox conrod is the fastest and cheapest solution i think if it works.

there is another option the hotrods rod kit

used by KTM talk builders in preference to the pro-x because of the bronze bushing and maybe a better choice since we see here a prox failure but this is probably one of Taffys kits so its not a true test of an unadulterated prox rod kit

Let's start again.
I have an old rod and new. Both prox.
The difference is in the big end pin.
The new pin from KTM is 5mm longer, and has oil hole closer to the edge.

I had a ktm 450sx rod kit installed in a 470 crank. The pin is too long. I told the machinist to make sure the oil holes match up and not to worry about the length. Looks like I'm going to be doing some grinding. I will post some pics when I get the crank back.
 
it is difficult to imagine that prox had shortened the original pin? they are always 64mm long?

who did you get the first kit off?

that first pin is a bodge up! who did that? they have tried to get the oil feed which comes in at 15mm inboard from the edge and make it go along the pin until 5mm from the edge and then goes through the original hole.
