camatv Posted May 17, 2013 Report Share Posted May 17, 2013 why would you NOT run the TZ or roller side with stock angle gears???????? thats the BEST bearing you can run?? i have run roller on the drive side with ANY upgraded build that will use stock drive gears. they make the flex non existent in the crankshaft. you will NEVER have a bearing issue if you run that setup. ( unless you run a china bearing or install it all wrong or some other issue) if you have a higher hp cub OR serval its a great easy cheap upgrade to the crank to run a roller bearing on the drive side. i will not build a motor up unless that is one of the things done to the crank. do a few searches and you will find a bunch of higher HP motors with blown drive side bearings from the side load of the angle'd gears. its threads like this with bad info that leads to bad rumors.

sprinklerman Posted May 17, 2013 Report Share Posted May 17, 2013 TZ and maxload. Call TDR,great deals on them. Quote Link to comment Share on other sites More sharing options...
camatv Posted May 19, 2013 Report Share Posted May 19, 2013 the tz or roller style bearing can take HUGE amount of load and live to see another day. with the ball style ( oem style) and the twisting motion of the stock angle cut gears with higher HP can lead to all kinds of problems. i think i still have a crank out in the shop with a cracked bearing on it. higher HP motors with crap crank bearings will blow crank seals, then crack the bearing, and/or seperate the keepers, then they can just plain explode. think about it like this the angle cut gears on the OEM side of crank- clutch cause the shafts to push apart. it makes them run quiet because of the constant mesh. on a 35-60 hp motor its usually not that big of a deal. you get higher in the HP and that pushing apart is going to get worse and worse. add in a non welded crankshaft thats going more and more out of true adn you also have all that vibration causing hell on the bearings also. either the main trans bearing behind the clutch is going to blow ( highly unlikely because of all the slop in the bushing to shaft) OR the bearing on the crank is going to go ( much more likely because of the direct pressures put on that bearing. ) Quote Link to comment Share on other sites More sharing options...
registered user Posted May 19, 2013 Report Share Posted May 19, 2013 if you put a roller on one side might as well put it on both sides. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 19, 2013 Report Share Posted May 19, 2013 I have many motors out there with tz bearings and stock primary's,no problems and I know a few of them like wacko 2000 relentlessly beat the shit out there motors Quote Link to comment Share on other sites More sharing options...
