Crankshaft Pulley Balancing

[AndyGT6]

Hi,

I am about to get the machining done on my crank pulley extension and trigger wheel so I can weld them together. Is it advisable to get the assembly balanced before refitting to my engine, or will it be ok as it is. I initially thought that as the work will be done on a lathe so the trigger wheel has no run out once it is mounted, it should be reasonably balanced from the outset. I look forward to any replies.

personally id get it checked just to satisfy my over worries mind!! whats to say it was balanced properly at the factory!

I'd say that balancing isn't strictly necessary, but it is nice to have a smooth engine. As the original pulleys aren't usually well balanced, it will make a difference, and you might as well do it after the trigger wheel has been mounted.

Remember the front pully has a rubber damper built in, don't use excesive heat!!
I bolted mine to the fan mount.

Hello, my crankshaft -flywheel-dumpers the check balance was perfect, all the components are new, steering wheel also no have problems of balancing.
Tomorrow upload photos whit the trigerwheel

sorry my bad english

Hi,

Thank you for the replies, I think I'll take a chance and fit the trigger wheel as it is, if I detect any vibration then I'll get it balanced. The pulley extension and pulley/damper have been separated as the extension locates on two pegs, so there is no worries of heat affecting the damper. Attached is a picture of the extension and trigger wheel, I'll be doing the welding next week hopefully.

Andy:

you machined the trigger wheel on CNC?

Hi,

The trigger wheel was purchased from Triggerwheels.com, one of my colleagues in work enlarged the original 1/2inch pilot hole on a lathe.
