No clearance

Dr_C · Sep 30, 2005

The axial clearance to the big end, I believe is correct (app. 0,4mm), but the main bearings (rollers) axial clearance is to small (<0,2 mm). I have made sure the mains are properly mounted and all inner races too.

1. Have anyone faced this problem?
2. I was thinking of grinding off the inner races, but what would you guys recommend?

Sorry Dr_C, I am not the one to answer your question, but...

As a Swede I invite you and all of us to make a bigger mark here. Although your skills in english leaves nothing to say (except approximately is better abbreviated "apx" as "app" is known as "application"). So I am A Smart ***...
Seriously, this is a heavily anglo-american site. Nothing bad about that, other than the fact that we are underrepresented.

Welcome to the Forum. (crap, youÃ‚Â´ve been here longer than me...)
I am sure you bring far more Husaberg Knowledge here than I do.

If you need specific translation in technical English, I am available.
That goes for anyone I can help with Am English or KingÃ‚Â´s English vs Swedish. No charge of course. Not everyone knows the difference between a monkey spanner and a monkey wrench. In Swedish.

Dr. "C",
You should be capable of adjusting crankshaft axial float via the crankshaft width. Simply push the crank halves closer together. If for some reason you end up with less minimum rod side clearance than required (.032") look for a problem such as improperly seated main bearings, etc.

Hope this helps.

Kind Regards,
Dale

protect the threads on the end of the crank and give it a bloody good slap with a dead weight rubber hammer or a copper hammer. this is STANDARD PROCEDURE at my engine reconditioners!

use the foot of a vernier guage to measure the 'step' from bearing to a shoulder on the crank. then slap the crank fully the other way. if you end up with your .2mm then you have found it!

Hi Taffy,
said procedure is indeed often required with "Ball Bearings", however,
such measures should not be necessary with regard to "Roller" units.
Sincerely,
Dale

PS
Have you received your parts?

As the axial clearance on the rod is 0,4 mm I do not dare to press the crank closer together. I have pressed the mains, with appx 3 tons, into the casings. I will check wether the seats for the mains are machined too shallow, as you mentioned, Dale. I just got hold of the CAD-files for the machining of the crank case, so IÃ‚Â´ll have something to compare with.

I checked the bearing seats in the crank casing and they are appr. 0,2 mm more shallow on each side, compared to my other engines. So despite having only 0,4 mm side clearance on the rod, I get about 0,2 mm free play at the crank. So, it's off to the machinist to deepen the bearing seats! Thanks for making me question the original machining, Dale!

I know who made all machining on casings, heads, covers etc up to 2003. Do you guys want me to crap on his driveway, or something? :idea:
