    Noise in transmission while clutch is engaged sm465

    Looking at the sm465 trans, this is the input shaft, the bearing is behind the 4 bolt cover that the clutch release bearing slides on. That cover/retainer only goes on one way as there is an oil way in it to feed the bearing. I agree with prairiedrifter check out GebBuilt on youtube there is a...

    Which clutch!?

    Hi Disco. One thing to make sure of before buying your clutch and deciding between the 11" or 12" version, check your bellhousing. Easy to do to know what you can or cant do. This is for the 11" clutch, note there is no big bulge on the bottom of the bellhouse, just nice smooth casting lines...

    Small block to big block swap. What do i need to know?

    Fastnlow86. I have an 88 454 mkiv in my 76 C20 square chassis. I was going to put an 4l80 behind it but the cost to do that didnt make sense to me. So I rebuilt my SM465 manual trans, and changed the diff gears from 4.11 to 3.42 in my 14 bff. Also im running the stock 800cfm qjet You can tell...

    Priming a New Water Pump?

    I put a gm serpentine kit on my 350 v8. All was great until the rear bearing on my alternator cs130 quit. The alternator is a reman in the GM performance 12497698 kit, and the rear bearing is too small in the stock 105A cs130. But that squeal was there all the time and got worse with rpm. I...

    Might have Over-torqued Rod Bolts 250 I6

    If you wanted to be sure you could plasti gauge the rods ends bearings to make sure the clearance is ok. Its your engine after all.

    Might have Over-torqued Rod Bolts 250 I6

    As marineone said. Remember to get a couple pieces of small hose to fit over the rod bolt threads so you are sure not to nick the crank journal as you replace the bolts out and in. Simple trick to stop some (more) cussing! You arent the first to have over torqued a bolt. Thinking about the...

    Might have Over-torqued Rod Bolts 250 I6

    Look at it this way. Do you want to pull the engine again and redo the bottom end if your lucky, if the rod bolts let go it could be rods through the block. Then you need a whole new L6. For the cost of a set of bearing shells and bolts. Replace them now, and know its good.

    Another speedometer thread, stopping and asking questions before I mess something up.

    BulletBob. That diagram is from the factory manual. Which if needed I can copy and do a pdf link from drop box. But you can go to places like this. http://tcase.rsgear.com/technical/diagrams/transmission-articles/gm-sm465-4-spd.aspx And see a breakdown of the 2wd and 4x4 box. Item 61 is the...
