How do you get a manual trans to "slip"?

 

I think he means his clutch is slipping, really no fault of the trans, usually is user abuse, even the greatest trans clutches slip, just put one in a 379 long hood pete

 

I will have to look more into this. If I can get a 4bt putting out as much or more than the 5.8 and get 30 mpg, I would be all for it!

 

I kinda figured that but I had to ask...

As far as clutch life goes when I sold my '95 379 two years ago the original clutch had 1,920,000 on it but I attribute that to a good operator (me!) and the 15 speed trans with deep reduction gears that really made it easy on the running gear when starting off on a hill or with a heavy load (of course I never hauled heavy...)

 

i figured u were just ribbing

ya this ole girl has a little over a million and we put all the "new guys" in it, they usually aren't easy on the clutch lol

 

Your desire/pocket is the limit with these...they'll handle anything you throw at them. My power level is modest all things considered.

There are two common pumps with these, the ve rotary and the p pump. Either are fine for modest power, p pump is easier for big numbers but it's much less common. There are other pumps that came on the 4bt, like generator and other tool applications, that have very weak pumps and would not be good for a vehicle.

The mods are the same as the 6bts so there is infinite information on what can be done. Well over 200 hp for either 4bt pump is very easy and basically free.

 

How does the 4BT do for towing? I'd like to repower my F350 with a diesel to tow my 6K trailer. Found a couple reman'd Hercules but they are a bit too long...

 

U would want a 6bt out of a dodge

 

for any kind of towing, a 6bt is normally the best suggestion.


HOWEVER....the obs fords are substantially lighter than their mammoth successors. if youre towing light, which you are, a 4bt with the free mods will do just fine especially if you drive around a lot empty in between tows. stock itll be a turd.


Hercules are just too sluggish to do anything, even normal driving.

 

Your 350 will handle the weight of the 6bt, you can also pick up a 6bt more readily and cheaper than a 4bt if i had a 350 gaser I would put a 6bt in it. Everyone wants a 4bt right now and people are asking 3k for them when I saw 6bts for 1k all day

 

Unfortunately the guy I got it from was third hand. He got it from his buddy. They're both Land cruiser guys so it was half way into a land cruiser before I got it. I got the Toyota adapter on it now but I told him I would give it back. I'm hoping that the flywheel will not need to be changed. Is there a way to find out if the flywheel will work? Count the teeth maybe?

 

flywheel depends on your transmission, youll need one for your trans of choice. I doubt the one you have will work, it likely had some 4 speed hanging off the back. you could buy a cheapo for whichever trans you want, and visually confirm that the one you have can or cant be used.

 

Good idea I really think it will be easier\better for me to get a tranny (pockets allowing a zf5) put it together outside of the truck and drop it all in. Im really wish I could find that ford/4bt adapter plate. Most people refer to it as a for small block adapter. I'm also hoping that that plate will adapt a zf5. I have heard of some people using the two with no issues. But I need that plate! Uhg

 

yep that's what ya wanna keep your eye out for, ive seen a few on craigslist and ive gotten a couple over the years. small block zf's are abundant and dirt cheap also, so its win-win if you ifnd a used small block adapter.

 

Yeah. The po replaced the factory one at 100k for no reason with a cheap Chinese one like he did with all other wear parts that I've had to fix. 65k miles later plus a couple times when I've pulled stuff bigger than I should, it's slipping a little. I'd like to put something a little more heavy duty in.
