1976 CJ7 Jeep with a engine/tranny/wiring harness out of a 1988 s10 blazer 4.3l v6 with th700r4 automatic tranny and a cj7 Dana 300 transfer case with Novak adapter.
Complete wiring harness from the s10 blazer. Painted with HOT PINK Pearl paint with standard sized metallic halographic pink flakes. Painted by me -a newb. New rear, front and side three wire LED lights, New parts, new custom dash-by me And a lot of guidance from fellow jeepers and lots of prayers etc.... :p
So, I decided to install a 4.3l v6 TBI with th700r4 Transmission from a 1988 Chevrolet S10 Blazer into my 1976 CJ7 Jeep.
I contacted Novak adapters and Jeff was extremely helpful with my many questions and uncertainties of which kits I would require. After I felt comfortable with the parts I thought I needed I went ahead and made the order with Jeff over the phone.
Here is a list of items I purchased for the mod:
Kit 172 adapter 700r4 to Dana 20 Transfer Case
6 Spline Transfer Case gear
RM103 Transmission bracket and mount kit
(I didn't need some of the items they had for sale like the motor mounts as I already had a pair).
When I ordered the items, Novak was in the process of manufacturing the adapters, but it took just under two weeks to get the adapter kits.

Upon receiving the box, I opened it and took account of the parts. Everything appeared to be there. One good thing is they pre-assembled the main adapter. I also got a four page overall description of the th700r4, how to identify one, compatibility among other things they have for sale, and two short paragraphs with instructions on how to install the adapter. No pictures or installation instructions that a novice could feel comfortable with going forward with the install.

So, I contacted Novak to get some questions answered.
Jeff was not available (Fri July 3) perhaps due to the holiday the next day. But I did speak to another representative who was not as helpful. I will not mention his name but he was quite blunt and say that the parts and adapter and spacer can only go in one way. Perhaps it would be easy for the vetran builder. But this is my first time ever doing an engine swap and I want to make sure it is correct the first time. Especially after spending close to $1000 on their parts including shipping, and purchasing a Blazer to install the engine and Transmission in the jeep. Not to mention all of the labor I have done to remove the parts from the jeep and blazer.
I then said that the instructions say to apply grease to the Transmission spline and gear that go into the Transfer Case but doesn't mention the type or how much. Novak said to use as much as or as little as I want and that wheel bearing grease is fine or the grease in the grease gun. (If anyone can confirm or correct this please let me know).

I then visited their website again to see if I could find any pictures of how the adapter is set up. There aren't any pictures that specifically have my adapter but it did show how the Transmission mount should be installed. I was just playing around with how the adapter appeared to fit the best. Thinking I got it right, I installed the stud bolts into the rear of the Transmission then put the adapter sub-plate, (which is shorter than the adapter and goes between the adapter and Transmission ). I then lined up the Transmission splines to the adapter and easily slipped it on but then it stopped 3/4" before the sub-plate. I tried this several times same issue.
It was quite late when I discovered this issue, so had to send Jeff an email. Someone mentioned that their website they require the Transmission shaft to be CUT in order for the adapter to fit! I told them that I thought that was only if the Transmission was 2wd as mine is a 4wd version. I would have appreciated knowing this from the beginning. As I don't have the skills or tools to CUT a Transmission spline. If this is true, then why not make the adapter longer to not require this head-ache? I thought I would get an adapter that was easy to install.. Not one that requires to butcher the Transmission spline.
I plan on contacting Novak this Monday to hopefully figure this issue out. :confused::confused::confused:

If Novak doesn't make a simple adapter to just bolt to the Transmission and my Transfer Case , would ANYONE know of a company that does??!?!?!:(

I would call Novak on Monday and deal with Jeff.
Show him the pictures you have shown us.
Good luck and keep us posted.
BTW: A 'cut-off' wheel can cut(shorten)that spline.

I agree with Grumpy. But first, using a flat bar across the surface of the adaptor measure the length of the shaft. On the other side do the same thing and measure the depth of the hole. If the hole is 3/4" short you should see the difference easily. NOVAK has been in business a very long time and has about seen all of it, if you need to doctor the shaft it seems like they would have said something and said it loudly.

I admit to not being very familiar with your conversion, but there is a drive gear going into the Dana 20 . Try moving the shaft/gear to index the two gears together while sliding the two together.

He wants you to grease the splines to ease assembly. Since the grease will be going into a Transfer Case full of a lighter grease I wouldn't worry about compatibility issues. But I wouldn't use a whole bunch of grease though. Just a light coating will be fine.

That was an honest unintended Freudian slip my friend.

Darn, it seems like I'm ALWAYS working on my CJ. Some of my projects are on hold until I get my parts back from sand blasting. I'd like to put the front end in, but I need the CJ to pick up the sandblasted parts. If something goes wrong I'm stuck, so I wait another week for that.

Funny as he11!

I noticed that right off and thought, "Oh boy, here we go!!"

Hedge; sounds like you're having a "busy" day! Don't take medication with whatever else you're workin' with there brother :D.

Y'all have a great 4th!!
 
Honestly, I don't know why I wrote Grumpy, naturally I meant Lumpy. No, insult intended, Lumpy, grumpy no way, never got that impression..... well not often anyways.... :)
 
Hey, H'DOG, I know you didn't mean anydangthing by it-Just had to raz you some is all:D
Now -GET BACK TO THE "HEEP' WORK:D
:rock:

Thanks guys for the entertaining responses. :) I guess since it is July 4th, I will have to wait until Monday.. Possibly Tuesday before I can get some answers... Unless someone else can fill me in...
If indeed I do have to cut the Transmission spline, would anyone know of a machinist that can just make asub-plate adapter that is 3/4"-1" longer? That way I won't have to pay someone to butcher my shaft?

Thanks again for your help!

Happy Independence Day! :chug:

If they can't or won't take on the work, they might know someone that can help

It would be cheaper to just buy a 4-1/2 angle grinder and a cut off disc to shorten the shaft than it would be to make another adapter.

IF you do go this route-Be sure you keep the shaft cool so as not to lose the heat treat.
Best if you can to wrap the shaft with a wet towel and keep it AWAY from the cut-off wheel just a bit.

That, or I was thinking something like a Port-a-band with a high dollar blade and an extra set of hands with a spray can of lubricating fluid. Lot slower than the grinder and combined with the lube, virtually no heat.
 
Hey Guys,

I spoke to 2 people with Novak, they both believed the shaft didn't require cutting but I still have approximately 3/4" gap. So, I emailed them some pictures of the adapter, my Transmission and the sub adapter... Then waited. An hour or so later got a call, (name deleted for his sake) said that he spoke to the machinist and that I WILL need to cut the Transmission shaft...:eek::confused:
I stated that I don't feel comfortable doing so and their site is very unclear about this requirement. I further stated that I will need to find someone who could successfully perform this mod as I don't feel comfortable since it is the Transmission . :(
I also said that is the very reason I didn't buy one from AA since they require the shaft to be cut...

I asked if they offer a sub-adapter plate just 1" longer so that I won't have to deal with cutting up my tranny shaft. He said no. :(

It's very frustrating as the sales and tech guys both believed it wouldn't require any cutting.... It was only when he spoke to the machinist that he learned I would. :mad:
He assured me that if I wasn't able to find a skilled person (with a 2month grace period:confused:) to cut the shaft, that I can return the adapter and not be charged the re-stocking fee as long as it wasn't scratched.... (Does it count if it was slightly scratched when I got it in the mail?-I thought to myself... As it could have been better cushioned in the box..) :confused:

They seem like they want to work with me (:confused:) but I am disappointed and feel stressed about this predicament...

I REALLY don't feel comfortable to cut up a perfectly good Transmission shaft... What if I can't cut it straight? Also, the Transmission shaft is currently inside the Transmission and under the jeep, it's not like I can just take it out and put it on the vice-grips and cut it...
One other possible option is that I noticed inside the adapter there is approximately 3/4" (or so) of a straight ledge before it bottom's out... Wondering if I can get that cut to fit the spline angle or is that a bad idea???????????? :confused:

I appreciate all of your suggestions and advice! Please keep them coming...

I would have gone with advance but their website makes it look like I would need the 2wd shaft... And yet, I have the 4wd one. :o

:notworthy::notworthy::notworthy:
 
Just to give you something to look at for comparison:50-6905 : GM 700R4 & 4L60 to Jeep Dana 18/20 Adapter Kit | Advance Adapters
Good luck with your conversion, sounds like a great upgrade to be able to cruise to the trailhead with.


Thanks for your suggestion. :D
However, it appears that I would need to take out the 4wd shaft and replace with a 2wd one... But their website just like Novak's is vague... Also, neither of them have good instructions and no detailed pictures of how everything will go together.... :(
 
That, or I was thinking something like a Port-a-band with a high dollar blade and an extra set of hands with a spray can of lubricating fluid. Lot slower than the grinder and combined with the lube, virtually no heat.



Perhaps I could borrow your hands and port-a-band... :rolleyes:;)

Thanks for the heads up on keeping it cool.... :notworthy:
I don't have any tool that would cut the shaft... Hopefully I can find someone that can do a house call and has exact skills... :(
