First post and Help about Harmonic Balancer for 250 engine.

[Barbara Jean]

Hello everyone here.Been reading allot in this forum and all information.I bought my 1967 Chevy C10 about 20 years ago at an auction for $650.A guy was bidding against me only he wanted the bed.So he passed it up and I got it.I drive it up to a few years ago with a 292 inline six motor and it started smoking.So my ex traded me his 250 inline six for my 1965 GMC body and chassis I bought recently for $500.His buddy put the motor in two years ago.Well he said it still had the smog pump on it and I don't need it.So took it off and used the brackets for the alternator and smaller belt.Had two belts on and now only need one.Problem is the Harmonic Balancer is not pressed on tight.It was only staying on by the belts.I cleaned the HB and painted it.And cleaned where it goes back.There is nothing to hold it in.It doesn't take a threaded bolt.What holds it onto the post?I also have the 292 inline six on a crate and another inline six that I don't know what size.Do I pull the HB off the 292 and use it?

Here is a pic of my 1967 C10 truck.Manual tranny.Three speed with granny gear on the floor.Original blue outside and inside.Needs painted.Inside needs painted and new seats and floor covering.Old bucket seats and a homemade wooden box in the middle.Will get a bench seat soon.

No the 292 is threaded for a bolt on the crank snout the 250 isn't , you can have the crank drilled and tapped to use a bolt to hold the balancer on , the 250 is pressure fit and doesn't use a bolt . use the search box for many threads on your situation .

it looks like you have 2- 250's sitting on that pallet

Thank You.Yes.I was told it was probably a 292 but apparently not.I did find a photo of the difference between the two.Also found what the key on the post where the Harmonic Balancer goes is called a Woodruff key.My daughter's fiance came over and took the key out and will find one that is good.The one he took off my motor had a groove wearing down the side.Found the Woodruff Key photo.[IMG][/IMG]
