Connecting rod issue -CRF's Only Forums

NOGRP90 · by **NOGRP90** » Thu Sep 24, 2015 2:03 pm

Hi Guys,

I am new here. So I just bought a Prox connecting rod kit to my CRF450X 11'. When I opened the box I noticed that the part numbers of the connecting rod are not match with the box and foil label.
Basically it should be 03.1405 - box label and foil are ok but on the connecting rod there is 03.1402
As I checked It's for CRF450R 02-08' based on Prox catalog.

My question is that are these parts interchangeable? is it mixed or it's normal?
I know that lot of stuffs are compatible with that CRF450R model but I cannot decide that it's okay or not.

Any help would be appreciated.
Thank,
Roland

Welcome to the site !! $\:D/$

I am guessing you did not buy the parts here , which is why they might be wrong , as some places just want to sell you a part and not check into what it actually fits because some parts are interchangeable , so they just generalize and say it will fit , i see it on eBay all the time

PM Ken the owner here he can tell you exactly what you have , but the X crank is different as far as i know , from the R

I have contacted with the official Prox manufacturer and they said that the total length and some other dimensions is not same as 03.1405. So unfortunately it's not possible to use.

Thanks four your help btw.

BLOW MIND!

I have got my new replacement Prox connecting rod from official Prox Racing Parts.
I am so disappointed right now because I got again a 03.1402 connecting rod...

I would be grateful if someone could explain it. How could it happen again? They packed wrong a whole batch? Or after all it's compatible?

Before that I have called my local prox dealer and he said that 1402 and 1405 is different.

Any help would be really appreciate!

I replied in private message previously. All I can tell you is the 03.1402 is a ProX part number and ALL of their distributors show this as fitting the '02-08 CRF450R. None mention it as fitting the CRF450X. ProX does have a different part number for the CRF450X version. I recommend you contact ProX and/or the company you are purchasing these from to verify fitment for your CRF450X.

This guy tore apart his used 2007 CRF450X and it had the 03.1402 rod in it, so maybe it is okay. Also, I found the rod on Amazon and although the description says 03.1405, the picture shows the 03.1402, but it appears to be the same photo, so I wouldn't put too much emphasis on this. Do as Ken suggested and call Pro-X to find out for sure.

Technically there is NOT a 2011. However, some countries have "2011" but really they are 2009 models with 2011 designation for that country. However, the part number you mentioned is the 2002-2008 CRF450R rod. It may be compatible but I don't want to make that call. Talk with Pro X.

Thanks guys,

Here is the answer by Prox:

"Thank you for purchasing our ProX connecting rod.
The partnumbers are for different applications.

03.1402: ProX Con.Rod Kit CRF450R '02-08
03.1405: ProX Con.Rod Kit CRF450X '05-15 + TRX450R/ER '06-14

Please contact your dealer to exchange the conrod for the correct one.

Thanks for the information.

Best regards,"

It was a technical related question so I think he just followed the process. I also called the help desk and they said the same.

But I think you are right. It will fit. I ordered prox connecting rod two times from different dealer with same os number, it shouldn't happen by accident. In other hand I am not a native speaker so if someone else would call them too I would be really happy.

Finally, I got the right answer.

I have called my local dealer and they compared the 03.1402 and 03.1405 connecting rod. Both parts have a same part number on it.

03.1402-->03.1402
03.1405-->03.1402

The connecting rod of the CRF 450X is almost the same as the CRF 450R (1402) only the Big End side is 4.00mm wider therefore a longer pin. They use the 03.1402 rod for this model with 1.00mm washers and a longer crankpin.

03.1402-->61 mm - 02-08 CRF-450R
03.1405-->65 mm - 05-15 CRF 450X

I hope it helps someone else too.
