| | | | Joined: Aug 2006 Posts: 486 'Bolter | | 'Bolter Joined: Aug 2006 Posts: 486 | I'm trying to get the power steering brackets on my 292 and I'm running into problems getting all the pulleys aligned. First I found that a 2-groove water pump pulley I removed from a 250 wouldn't align properly. I think I have a pulley that will work now. Next I found that the alternator will not align properly with the crankshaft pulley. It's off by about 1/2". [IMG]http://i305.photobucket.com/albums/nn214/jfnar/68%20GMC/IMG_01071_zps8knboxog.jpg[/IMG]I have 3 other alternators and mounting brackets from 250's and 292's but they're all the same. I can make a new bracket to correct this but I'd like to know what's the correct way to fix it. Is it supposed to have a different mounting bracket or is there a different alternator pulley that will align properly? Thanks for any help. Jeff

Is there an alternator rebuilding shop in your area? If so, they probably have a good assortment of pulleys available.

Even the the alternator has to be shimmed forward by three washers in its bracket | | | | | Joined: Mar 2005 Posts: 1,636 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,636 | All the 292's I have worked on were in 1967 Chevy school buses. They had single groove pulley on water pump and alternator. But the alternator pulley was built so that it was 1/2 out further than the regular alternator pulleys were. Made line up perfect with no spacers and no moving the alternator.
I think I kept one of those pulleys because they were/are hard to get.
Most parts stores didn't know to change them and so many times the customer came back to get the right pulley. Sometimes the alternator had already gone back to the rebuilders and the pulley was with it. | | |
