- This video Part 2 of 2, will show you how to tap a crankshaft on the older small block Chevy’s. The older engines (283/327) had a press-on balancer with no bolt to hold it on. This vid will show you how to drill/tap out the front end of the crankshaft so you can then “Bolt on” a new modern quality harmonic balancer. I’ll be using the crankshaft drill and tap fixture tool kit from mrhotrod6.com. It’s a long technical video, but if you really want to do this, feel free to watch…
Thank you! I will be doing this job on my 235 Inline 6 with that exact tapping kit, now I have some confidence to do it! Was a little nervous but I see it's slick with that kit, appreciate you sharing this!
No worries, you can do it. Take it slow…thanx for the comment bro…
Finally found a video, thank you for share.
I’m doing a refresh on my inline 6 250 and came across this same situation, I pull the harmonic balancer off but have now way to put back and I don’t want to hammer it back 😂
Thank you. Just bought a ‘68 327. I was confused about not having a factor bolt in the crank; for the #harmonicbalancer. You’re #sbc #327chevy #283chevy video made my day.
No prob, glad I could help… yeah I went through the same thing…
I have a 66 327 sbc and harmonic balancer bolt won't bolt down thanks for the video
Great video...thanks for the tips and for doing this piece....
Thank you! hope it helped ya a bit...
You’re a genius
Hey Vince! Ha!...Funny guy. I'm working on the genius part. Thanks for the reply...
Great video thanks for sharing. I have a 350 small block , I noticed when trying to purchase this tool it shows for 283,237 but no 350?
Yeah I saw that too?? I know the 350 has a bit of a longer snout. But I’m thinking that the tool would work to tap that out, it’s the same bolt thread and size for a modern balancer. Good luck maybe call them and see what they say. Good luck with your project…👍
Not all cranks can be drilled.
I have the same motor, 283, engine completely rebuilt, at the same level you are, could you tell me the part number of the Balancer you got from Speedway, I already ordered the tap kit for the crank. I appreciate it thank you,
Hey Joe, I'll have to dig through my receipts and get a part number, I'll try to get back to you when I find it...Thx, Chris
Actually it would be a torsional vibration damper. And saves your accessories from vibrations. Does nothing to protect crank, internally balanced engine.
Hey thanks Ryan for clarifying, my bad. I appreciate the comment...
My 327 has the harmonic balancer on the crank , no treads inside it😮 now what?
Is the original balancer still stuck on? Anyway tap out the snout on the crankshaft , then you will have a threaded crank snout to bolt on the new balancer….
What size is the 2nd drill bit
Hey Jeff sorry about the late response. The small one is 1/4 HSS, and the larger one is 25/64 HSS.
You never said anything about the key way on crankshaft... I still needed to remove water pump and timing chain cover to remove key way...
Sorry man hope you got the project done, sorry for the late response...
Can I use just a regular harmonic balancer from a 350 afterwards?
Yeah it'll fit no prob...
Outbound Terrain thanks for replying 🙏🏼
Want to get rid of the kit now?
Funny I loaned it out and never saw it again. You Can get one at mrhotrod6.com though. Good luck man...
Which kit did you get cus there’s 2 different ones. 1 says 7/16 and the other says 1/2-20 but both works for 283 and 327 motors. Just want to make sure which kit to get before it get it
