Flex plate/fly wheel

[Maineguy10]

Yikes.........ok. What is involved with replacing/repairing the pump?

 

[doghead]

Well, a transmission rebuild(disassembly and inspection of everything).


Perhaps another member here that is more experienced with transmission rebuilding can offer a better explanation of what may be damaged.

 

[Maineguy10]

Bummer, thanks for your help DogHead. It all makes sense. I'll see what happens tomorrow when I tackle it.

Chances are you did not damage the pump, but rather bent the flexplate. If you bolted the converter on the flexplate before installing the trans, that was a mistake. allways install the converter on the trans first, then mount the trans to the engine. Never try to draw in the trans to the engine using the mounting bolts. You risk snaping the trans housing. If the trans input shaft splines are not lined up perfectly with the crankshaft, you will not be able to mount it flush to the engine. Rotate the flexplate, not the converter, to mate the input splines while a helper pushes the trans to the engine untill the dowel pins on the engine block are ingaged in the matching bores on the trans housing. Once the trans is bolted up, the last step is to bolt the converter to the flexplate.

Wish I would have seen this post a few days ago, I was just over in Lincoln. I may be back that way soon, let me know if you need help.

Thanks Wayne. That's today's project, see what I have gotten into for damage.
M38, I wish I had posted a few days ago. I just posted yesterday and got lots of response. Great site. Thanks for all the help guys!!

Here's a pretty good writeup on what I was talking about. Unfortunately, the damage is usually not visible without disassembling the pump.

Here's some general instruction/info.

FAQ :: Precision Converters of Ohio

and one more. http://www.precisiontorqueconvertersofohio.com/faq.html

Notice they do tell you that you will damage the pump, if you bolt the bell housing without the pump engaged correctly.

Personally, I would count on it being damaged, if we are correctly diagnosing what happened.

If you unbolt the 6 converter to flex plate bolts and cannot slide the torque converter back a little bit, or cannot rotate it then it is pretty safe to say this is your issue.

 

[Maineguy10]

Thanks DogHead. I will look that over.

 

[Maineguy10]

I took the chance, undid the tranny, slid it back a bit, and was able to rotate the TC and slide it back, the flex plate was bent a bit, but didn't seem bad, I took the chance and put it back together and didn't have any problems, all gears worked fine, started fine, starter didn't stick or anything.
Am I asking for trouble for doing this??

You own a CUCV... of course you are asking for trouble!

I do hope it holds up for you!

 

[Maineguy10]

Haha I hear ya, thanks.
Thanks for all the help guys!

Take a look at the flexplate with the engine running, if there is a wobble to it, both the flexplate and the starter bendix gear will wear prematurely. If there is any vibration above idle, you should replace it as it will take out the pump bearing and seal. Check the pump for leaks, as Doghead said, you may have damaged the pump. Only time will tell. If you get away with just replacing the flexplate, consider yourself lucky. Next time, if you are not sure how to make a repair, or it's a first time repair, search the TMs and threads or ask for help.

 

[Maineguy10]

Thanks Wayne. Will do. How do i check the pump for leaks?? It was my impatience kicking in that allowed me to screw up. I learned a lesson, so that helps I guess.

 

[wayne pick]

No problem, I've made mistakes when I tried to rush through a repair. you are not alone. To check for leaks, place a piece of cardboard under the converter, you will see any leaks easier that way. Of course if you see red, ya got a trans leak. If it's black, well it's a 6.2, LOL.

 

[Maineguy10]

Haha, gotcha, well it's in a garage now on a freshly swept floor just for that reason, checking for any leaks.
Thanks again,

You got it, remember, don't be afraid to ask for help.

I don't know if it will stay okay or not, but I will say that you did 90+% of the work required just to change it anyways...
