Does anyone know the SAE belhousing size for a Cummins small cam, DD671, and 8.2 Cummins. I was told the bellhousing required is a #2. I'm gonna change from a 10 speed Fuller to an Allison. The belhousings are about $450 new. A whole bus can be found cheaper than buying an Allison used. The Crown needs a MT654. Any suggestions and information appreciated. Frank | ||

Hi Frank, If you have the 10 speed now, that's got an SAE2 bellhousing. The 654 also is SAE2. SAE2 bellhousings can be bought for the Cummins engines- talk to Don Fairchild about the DD, I dunno 'bout that one. Finally given up shifting the Crown? I don't blame you....  | ||

How To Determine The SAE Number. Take a look at the chart below. Stand facing the bell housing while it is attached to the engine and simply measure across the face of it to get the SAE number. To check your measurement you can also count the number of bolt holes, bolt diameter and bolt size. Generally speaking, most small engines like a Perkins 4108 are SAE 5, engines from 60 to 80 HP like a Continental F163 or Perkins 4236 are usually SAE 4 or 3, and engines above 150 HP are usually SAE 2 or larger. Because the tendency in the last 20 years or so is to have smaller bell housings, it is now uncommon to see a SAE 1, SAE ½, or SAE 0. But they do exist. SAE BELL HOUSINGS MADE EASY No. Diameter No. Bolts Hole Diameter Size 1 20.875 12 .469 7/16 2 18.375 12 .433 3/8 3 16.875 12 .433 3/8 4 15.00 12 .433 3/8 5 13.125 8 .406 3/8 Sorry the graph didnt copy as hoped , but the Size info is here.
