To follow up on last month’s tip, here are a couple related items. Not one to buy a special tool for every job, there are instances when a particular tool does make a job easier and downright quicker. Throw in a trick or two and life couldn’t be better.

ATA 63

Bell 407: If you’ve replaced a number of rotorbrake calipers, you know what a PITA it is to loosen/tighten the attaching hardware. Especially when things are still a little warm and you’re trying to get a head of the game. Enter the 5/16” and 7/16” ratcheting “T” wrenches shown below. And don’t forget to start the safety wire and glue the shim before installing your caliper.  [Submitted by Rw]

 

ATA 63
Bell 206L-4: While the L-4 rotorbrake disc installation is not as tricky as the 407, there is a tip that can make it simpler. Install the correct K-FLEX compression tool on shaft and tighten hardware per instructions. Install the compressed shaft onto the transmission drive flange with two bolts and nuts at the 2 and 4 o’clock positions. Snug up hardware. Grab rotorbrake disc and insert into gap between free wheel unit flange and K-FLEX flange. Support loose side of flange as you push disc into position. [Submitted by Rw]
