OK - so I need help again. I have finally managed to split the crank (not easy like the old ones). The big end bearings and pin are shot big time. There are no markings on the bearings and in the parts list there is only a complete unit available. So what and where do I get a new set of bearings and a pin from? Anyone know? A new crank is 1000 euros (ouch). I would rather replace the bits that are damaged. (not that they should have been damaged anyway after only 400,000 km). Cheers........Fulgur. | ||

Oh - I have a 2005 XB12R by the way.  .....Fulgur. | ||

I asked Jens of Hillbilly-Motors to chime in. You should be able to purchase just the new bearings and pin. | ||
| Fulgur |
Thanks Blake - I have to speak to then anyway as I have an outstanding order with them. .....Fulgur. | ||

Fulgur, you have Mail. Jens | ||

Jens - yep. I've sent you my address. It is also on my badweb profile. Cheers....Fulgur. | ||

My experience, and that of Funjimmy, was that new bearings still need to be sized to the pin and it is a very fine tolerance. Hone, let sit overnight to cool, check fit. Hone again. It is somewhat of a crap-shoot as to whether they will get the sizing done for less than the cost of a new crankset, which is about $600 Cdn. If I was to do it again, I would just buy the new set. I assume that the factory, rather than honing parts to fit, just selects bearings and pins that match, out of the huge assortment that comes off the line. | ||

Are they still actually hand selecting parts like that for crank bearing fitting? If so, H-D needs to improve the manufacturing tolerances to eliminate that ridiculous antiquated routine. Good grief. | ||

Well I don't really know, Blake. The output shaft, if that's what its called (of the crank) has a variety of different possible diameters, which are adjusted for by using different size bearings. I assumed a similar process for the rod-pin set based on the fact that the cost of an over-size pin and bearings plus shop time to fit it was almost the same as simply buying a new set of rods with pin. Maybe just a case of what the guys in the factory get for wages versus what I have to pay for shop labour. | ||

Sportyeric - I know where you are going and you are right that the crank shaft rollers have to be very precisely selected (see the workshop manual for the "how too"). I had to go through that proses of measuring my new crank assembly and getting the relevant rollers. That is why I wanted to just get the pin and bearings that hold the con-rod big ends to the fly wheels (the bit that was broken) only, so to save me all the hassle and should have been cheaper. I did a lot of ringing around etc and unfortunately no one seemed able to help me and my current workshop isn't kitted out for that kind of work. So, I ended up getting a new crank assembly and doing the whole job anyway. It cost me a bucket load too. So answering my own question at the beginning of the thread:- No one knows the part numbers of the bearings or pin. No one in Europe is either capable of or admits to being able to machine up and harden a simple round bit of steel with a hole through it. No one can get hold of bearings that size. Seems that either Buell have kept these parts very secret or dealers, machinists and after market shops are next to useless in Europe. Just get a dam new crank assembly, pay the money and save the time. Not all bad news. The bike is back on the road and I will treat this as a learning experience. .....Fulgur. | ||

or dealers, machinists and after market shops are next to useless in Europe. Fulgur, have you ever talked to Bernd Kramer from http://www.kramermis.de/ or to http://www.motoren-wladarz.de/index_html.htm or to http://www.micke-technologie.de/ about your problem? Have you tried one of these addresses at the least? Ralph (Message edited by xldevil on December 03, 2007) | ||

fulgur i think for a 1000,00 euros you spent it was better sending your crank to hillbilly and getting it back with new pin, bearings and WELL BALANCED also . maybe it was cheaper...just a guess. bye Alessio | ||

The roller bearing up to 2007 models is still the one used in the older Sportster engines (basically part number 24354-87A, ask for the latest version, there has been an upgrade to new cages). Crank pins and washers can be made without major problems. Don?t know about the rest of Europe but we can do it . Regards Alex M-TeK Engineering (Message edited by Alex on December 05, 2007) |
