K & B 3.5 flex shafts slipping?

riggerman · Jul 28, 2019

Hi all I purchased several spare flex shafts for my K& B 3.5 2 summers ago noticed they where slipping on both of my 3.5 on close examination and digital calipers on the stock K&B shafts they measure 3mm on the square end on the replacements they measure 2.8 mm. Has anyone had this problem ? thats the good news i also bought 6 spares for my O.S .21 looking at them from the side the
square end is about 3/16'' shorter than the stock o.s units i will have to try to find where i bought them im thinking NY state. Regards Andris Golts

There were some that came from KB that were a little on the short side. I was able to put a ball bearing in the prop shaft to space it out. This fixed the spinning problem.

Hi Kris the shafts where not bought from you the seller was in the northern US i will see if my credit card statements have the company name. Regards Andris Golts.

Hi Andris,

While that is positive news for me...not a help for you. As Mike said, I had heard of people using spacers but not for many years. Hyperformance, lawless and my shafts should be no worries, unless someone had a big malfunction.

LMK if I can help in any way...not sure how, but we shall see
