Thread: Any body used a gear drive before?

Tweet

Anybody have any experience with those noisy gear drives? any good? what brands?

I've had lots of "experience" replacing them with chains when they quit working, does that count? You couldn't give me a set.

They create some very nasty harmonics in the engine that will pound valve trains to pieces... I'll take a good double roller chain any day.

Advice on gear drives - don't. Really . . . . don't.

Another point a guy brought up at coffee the other day against gear drives, all those nasty old harmonics must also transfer into the distributor and eventually start pounding all those neat little electronic gizmo's apart....Whatcha think????

that is what i was thinking, thanks for the info, would love to go the jessel belt drive route but thats alot of mony

i hope you was not thinking of one for your 632? i will not put one on or build any engines with one. like said there great for transfer harmonic thru the valve train can you say busted springs .just buy a good chain set like a rollmaster and call it good .if you want a jessel i maybe have a good used one

that it will. what do you think what happens to the roller lifter needle bearings they see it right off this stuff could keep you up all night

Grumpy Jenkins used to run the nylon/plastic tooth stock chev type stuff

Dampened out the dpark scatter caused by the harmonics

Course he changed them every night
