Dave,
The question of balancers has come up in other posts. Is it safe to say that you can use whatever 215/235/261 balancer that matches the fan belt grooves in the water pump and generator?
Thanks,

Because of the larger diameter it will turn the fan faster than designed for. This can flex the fan more than designed for leading to cracking.
On vehicles that have a high ratio rear end, or an OD trans, so sustained high RPMs are not likely it is even OK to use the pass balancer.

Chevrolet: Post links to photos of front/rear of the water pump. That will allow distinguishing new-style (high pressure engines) from old style (low pressure engines): 41 to 52 series ( use this pulley for 53 to 55-1st); and, 55-2nd to 62. The diameter of the balancer will allow distinguishing newer car from truck and older car. Width of the pulley groove will distinguish years. The width of the pulley-grooves can distinguish the years that used that width: 5/8" 37-52; and, 3/8" 53-62. | | | | | Joined: Sep 2010 Posts: 90 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2010 Posts: 90 | the diameter of the balancer that came off the 216 is in the 6" range and the diameter of the balancer that came off the 235 is in the 7" range | | | | | Joined: Sep 2010 Posts: 90 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2010 Posts: 90 | Thanks for all the great info!!!! Without all of you I would definitely not be moving closer to getting my truck back on the road!! This is a must resource to have when dealing with these great trucks!!!
