730d fly wheel

[KENWORTH]

hi all. i had flywheel problems a couple of years ago, on my 730d (main engine) I replaced it with a taperlock version, with a large square nut. i heard something ticking in the flywheel cover. i removed the flywheel cover, only to discover that the flywheel assy. had moved out on the cranksahft aprox. 1/4". what do i need to do now? any ideas of how to keep this from happening again??? thanking you in advance. bruce

Hello, you need to make yourself a wrench. I made mine out of a 1/2" thick piece of flat and put a 6' handle on it. Chain the flywheel from turning and lean on the handle,then take a mall and hit the webb of the flywheel. Repeat this until tight.

A friend of mine had the taper lock and slipped like described. We put in place and got pipe wrench and cheater and tightened,only thing it tended to strip the threads. The compession steel piece had tough threads but the square bolt had soft threads. My friend had another nut made and it tighted okay. The key is in the sleeve and nut and don't put lubricant on the bevel part that wedges. I guess in it's day it beat changing out flyweel and crank but I wasn't impressed with the setup.

One of the secrets is that you don't use the nut to tighten the flywheel, you hit the flywheel with a large hammer, then tighten the nut. Then you hit the flywheel with a big hammer and tighten the nut. Then you hit the flywheel with a big hammer and tighten the nut. Keep doing this until nothing happens.


Don't hit the nut with the hammer. Tighten the nut as much as reasonably possible, and save that last "monster" pull for the end.

ok, i have convinced the flywheel to move into what i think is the correct position. the wedge is NOT flush with the end of the crank shaft. it protrudes aprox. 1/4".i still need to tighten the nut. it seems tight, but there is about 1/8" air gap between the nut and the face of the fly wheel. any recommendations of how to tighten w/o the crank/flywheel turning? THANKS SO MUCH/ bruce
