I purchased the water pump conversion plate and new water pump. Instructions on the pump conv. plate indicate I need a harmonic balancer from a '53 or '54 so pump and fan will run at the proper speed. Both my generator and new water pump have 3/8" belt fittings. I have an old harmonic on my 216 but that is 5/8". Any sources for a new or used harmonic balancer or do i just return the pump and plate and go with the new short shaft water pump?? | | | | | Joined: Apr 2009 Posts: 554 'Bolter | | 'Bolter Joined: Apr 2009 Posts: 554 | If you can return the pump or exchange it another option is to use a 1952 or earlier pump with the 5/8 pulley and use your 216 balancer. Depending on your generator/alternator/voltage choice you may have to change the front pulley on that too. I went with a 216 balancer, 1952 pump with adapter like you have, and took the pulley off my 6 volt generator and put it on my 12 volt generator.

Just wanted to verify that the balancer from the 216 will fit the 235 and that it is the correct size.
Thanks,

All the people with actual experience say the 235 and 216 balancers are interchangeable.

Pete | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | My instructions also say you can use a 1955-62 truck balancer if you are running a 3/8" belt.
