Tail shaft case

scott · Post by **scott** » Sat Aug 01, 09 3:43 pm

I keep breaking the rear case on a 727, any ideas what would cause it??

mountings are new,

prop is new,

and the drive train looks in line????

You have a severe case of Heavy Right Foot. I prescribe a Fiat Cinquecento for a month. It won't help but it'll be a laugh to see you drive it!!!

Apologies for unhelpful post!

tail hsg,s do break occ,
should not keep happening,
you either have an alignment problem or a balance problem, you must
stick with a rubber trans mnt even when you run solid engine mnts or a mtr plate, most break because they have bad prop uj,s also if your a berk and keep burning the car out gettin the rear axle bouncing up and down they break tailhsgs,

hope this helps

New prop and uj's, new rubber mount.

only happens at the nats every year,

could the shaft be bent ?????????

Scott you might want to try and figure out what you do at the nats every year

does the box have to be stripped or does it come out the back??

had two props let go both at the rear thats why i had new one made this year.

If it is bent do you have one?? how much??
