crank

Gentlemen, Trying to put together a strong bottom end for roadracing. I have a 2005 FS650C with under 300 miles on it, including 90 miles on a 3 mile road course. The quick version to my troubles is the inner oil filter cap o-ring sheared when the previous owner installed it. A 3/4" (1.8cm)...

Just having a a look through the rebuild manual and saw the specs for measuring across the crank outer webs (60mm +- 0.05mm). When i measured mine it was 60.06 at the crank pin and 60.18 opposite the pin :shock: Ive got a feeling i should be worried about this? :? Wish i hadnt...

Been talking to Taffy about this problem - can't understand where the thrust/shear required to break this came from....... No galling on the end feed at in the LH case. No dramatic failure of main brg. I am seeing messages about loose nut and this is a possibility but the gear and key are...

had this trouble before so when i came to my first bike with a lose gear on the woodruffe key i had no hesitation in using an old cure. holding a long peice of lockwire, feed the wire to the side of the woodruffe key and then get the gear on and started. then tap the gear down the...

just asking aloud what is the engineering code that a main bearing should fit onto a crank? someone said to me K7 but i'm not really sure? regards Taffy

can anyone tell me the correct crank float on the 07 and 08 bergs. I want to check some new bikes by taking off the ignition cover and measuring the float against correct specs. Also how are people checking valve clearance on the 07 and 08 bergs. Are you using feeler guages or some much of...

the screw in the left-hand end of the crank has been loose on a couple of occasions but luckily the thread halps it to stay in. it has two flat faces for a special spanner and a jet through it is deliberatley small just to slow the oil pressure. There is another in the big end pin where the...

just purchased an 04 550 fe, on my first ride l noticed some oil running down the crank case just in front of the water pump housing. there is a small hole in the housing which l presume is for this, but being my first berg i just want to be sure. any help would be appreciated.

Hello Gentlemen Berg is still in pieces due to main bearing crash last september.Now i'm putting things back together and have some questions.. I am planning to install SKF NJ206 ACP /C3 HVC058 roller bearings,both sides+weld crank pin to halves.Pictures coming when it is done. Any...

Hi there new to the site just looking for parts to rebuild my fc600 engine had big end give up on me so i need either a complete crank or rod set any help apreciated.

I decided to check the crank since my engine is apart. I mounted it in the lathe and was surprised by the readings. Very similar on each side, but they indicate the crank has "spread" during operation. Measuring across the crank wheels confirmed this. Months ago when I talked to Fryguy about...

hi all what method is used to set crank end float, i'm not sure if a main is about to collapse ive got a metalic clank every now and then at tickover ,i checked in the cam box and behind the clutch cover, the only thing i can see wrong is the flywheel moves in and out when running and i'm sure...

I have a 01 fc 550 need the crank balanced, because I removed the balancer. It seems that knowbody in the area wants to do it. Please Help! Thanks, Rett

I notice the crank stop bolt has a plain "thread rolled" end on it. Is it meant to just push up against the crank at any location? On my prevoius bike (KTM RFS), the crank stop bolt was pointed and engaged in a v groove in the crank wheel. On a Husaberg does one just find TDC and then screw the...

Does anyone know of a good shop in US to rebuild the crank? I will be removing the counter balance, but I think there will be spacer needed to replace the bearing and spacer of the counter balance, is this correct thing? Mars

I am in the process of rebuilding a KTM560 SMR that lost it's crank bearings after 6 hours.(brand new) I see that KTM and Husaberg both specify to only shim for proper clearance on the ignition side. Is there a reason to only shim that side? The reason I ask is when my crank was removed...

We went for a wet ride this past weekend and towards the end my bike was cranking very slowly and wouldn't fire. I kick started it with no trouble and rode for another hour or so with no real problems starting with the button again, until this am. She wouldn't start at all. I was short on...

Hi all, :) Just suffered my first crank failure on my O3 650. I know Husaberg have tried to adress the issue in 04 by destroking them from 650 back to 628 ( although my manuals show the 650 and 628 both with an 82 mm stroke ?? dont think so) And in 06 they have upped crankpin dia from 32 to...

Hey Bergoroadracer' I was looking at your gallery and saw your crank vent. I assume you have blocked off one of the vents. Any problems with presser buildup? Also Do you have a part number for your check valve. That is one of the cleanest installations I have seen. It sure would clean the...

Help I tore down motor found that the counter balancer gear and the gear on the crank are missing teeth 8O any idea what would cause this :?: is there bearing failure that would cause this the mains feel tight and so do the counter balancer when I replace these pieces crank gear and...
