    TH400 Bolt on yoke problems

    With the yoke on the outputshaft and inside the extension housing there is no movement at all. I had checked the movement of just the outputshaft without the yoke installed and there was only a slight side to side movement not fore and aft movement at all. Of course with the yoke installed and...

    TH400 Bolt on yoke problems

    Ok I am sorry I haven't been keeping up with posts. And thank you all for your help. Ok as far as putting shims on the yoke I thought of that however the way it is designed the splines go all the way through the yoke and there is a big washer that caps off the yoke and the bolt goes through the...

    TH400 Bolt on yoke problems

    Ok this may have been the problem. Picture #2 here is showing the old bearing and where it was pressed on to. It was pressed in the middle area of the three different diameters of this shaft. Picture #1 is showing my new center bearing which is much larger in diameter than the one that came off...

    TH400 Bolt on yoke problems

    I have an 86 dually and I have replaced the 454 with a chevy HT502 crate engine and the stock TH400 with a B&M Traveller TH400 transmission. Everything seems fine but my bolt on yoke seal keeps destroying itself. The first time I changed the seal I reinstalled the yoke but left the bolt a little...

    I have an 86 chevy c30 dually with a th400 trans fixed yoke 2 piece driveshaft. I recently put in a new b&m traveller TH400 transmission and when I did I had to swap over the tailshaft yoke from the old th400. At the time I just put in a new seal for a th400 and now it leaks. I did notice when...

    Dually crew cab exhaust.

    I was looking for an exhaust kit for headers. Do you know of any that will fit? Should I just buy a build your own exhaust kit? How much would it cost to have an exhaust done at an exhaust shop? Should I go with 2.5 or 3"? I just want enough towing power to pull my trailer uphill at 70mph. Also...

    Dually crew cab exhaust.

    Ok I have an 86 dually crew cab long bed with a 454. The factory tube manifolds (dare i say headers??) well anyway they are cracked. It still has both air pumps and tubes connected. On one side of the exhaust (or what is left of it) is rusted off behind the muffler no tailpipe at all. The other...

    Big Block Towing Motor

    I live in Oklahoma our summers are over 100 degrees. I hate anything that puts hot air back int an engine. Like egr and other crap. Are Holleys not good on a big block? I have a racecar and we have to run a 500 2 barrel Holley so I'm comfortable with them.

    Is the qjet going to work better? This is my first big block so I'm open to suggestions.

    Big Block Towing Motor

    As for the carb that old qjet is pretty worn out. It's got so many vacuum hoses on it that it makes my head spin. I prefer the keep it simple approach.

    Big Block Towing Motor

    I was thinking of a Holley carb on an eldebrock manifold just to clean things up. Same with the exhaust. The stock manifolds have that belows on them i dont like. I guess the factory brackets would work but i would have to do some homework for the right belts.

    Big Block Towing Motor

    Ok I just got my 86 C30 dually home with a big block 454 and 4.10 gears. It's awesome. It is completely stock and untouched. Here is the bad though. All that emissions crap is all over the motor. I plan on putting headers and exhaust on it pulling off that intake and old q-jet carb for a good...

    AC Hose help please

    I have an 87 chevy V10 4x4 truck. The truck is a custom deluxe and did not come with factory ac. I have installed factory ac from parts from the junkyard I think the donor truck was an 85 or 86. I've cut a new hole in the firewall built an adapter plate to cover the old one. All the ducts are in...
