harmonic balancer bolt (again)

[fccool59]

does this look like the correct bolt to use when fitting a bolt to prevent the balancer from coming off, its a chev 7/16 bolt.


Also i heard something about drilling the end off the bolt to put wire through since a lock tab cant be used, anyone done this?

Hi Leon,

My balancer was supplied with the correct bolt so I didn't have to buy one, but the one you have shown is good quality but looks too long to me.

Instead of wiring the bolt head why don't you just use loctite? Simple and you don't need to do any extra work.

By the way, how bloody pricey are these ARP bolts. I used them for me flywheel attachment bolts. EXPENSIVE!!!

Cheers,

Craig.

Craig, it was either this 7/16 bolt or a 1/2" bolt they had in crank bolts, i thought it looked long, what the hell am i going to do now!

everything i could get in arp i did but yeah, they are pretty dear, i had to get gm flex plate bolts, they were only $1 each at american autos, they only had arp for manual flywheels but i bought arp chev torque convertor bolts, everything inside the motor is arp except the head studs (well kinda) all the outside bolts are hotbitz, the head studs were made from two milodon chev mains kits wich cost a fortune, later i found out american autos get arp kits now for holden headstuds and they are only $99 a set, less than half what mine cost but i get a couple spare.
I wanted arp, whats funny but is i noticed it says arp on the milodon nuts.

i was told to use wire and loctite a few times, maybe thats excessive paranioa.

l've seen the damage balancers do when they come off a few times,but all l've ever used is loctite on them(green on the balancer-shaft-fit & red on the bolt-reds stronger than blue-l cant remember theyre numbers) make sure everything is CLEAN- l also use loctite primer l think its 7471 from memory a little green & red aerosol can its cleans everything ready for assembly. lts not cheap but it lasts for ages & considering the alternatives its cheap insurance l reckon.      Daz.

Green would be 609 and red most likely 262 . Hope you dont want to get it off in a hurry.

if the bolt is too long you can get a nut and wind it on to bolt right up to head (if thread goes all the way up that is) if threat stops short use washers to bridge gap then place bolt into the the balancer bracket and tighten bolt as far you can after this you do this take the nut you placed on in step 1 and move it back down the bolt away from the bolt head to take wobble out. p.s. like other i say loctite it
