Center diff adapter for hyper 7 (pics).
 

After seeing rchippie's buggy with the center adapter that mike had made for him. I talked Mike and he made me a center diff adapter to fit a Ofna 51t plastic spur gear to my Hyper 7. It's beautiful. It was made from a solid piece of aluminum and it fits nicely. I've got it in my buggy but, have not had a chance to run it with the new adapter yet. This is a good way to go. Here are some pixs.

The pictures don't do it any justice.

On the diff.

that looks good. make me want a pretty one like that for my center diff.

what diff do you have? i have a 8 spyder pcr edition but it has 8 screws.

I have the RTR version it has 4 screws. I did't realize that the 8 spyder gear had more screws. I was thinking I could upgrade someday down the line, guess that won't work. If you need an adapter, I'm sure it could be made with more screw holes.

Looks good. How much did Mike charge for that?

just checked and its 6 holes instead of 8 :o

That looks great you will br pleased with it.

I think so too! It is also much lighter than the steel spur.

As far as the price goes, email Mike because I'm sure that some adapters might cost more than others.

Old thead but do you still have that adaptor. How is it working?
I want one.

Mike does make some awesome adaptor's. He made one just like that for my 8 spyder centerdiff. For the price he charge's, you can't make one yourself at a local machine shop.

I emailed him for one hopefully he can make me one!!!

Here is another alternative.

Kyosho makes a 46t plastic spur gear part# IF148. This is a direct fit onto a Hyper 7 diff. you can also use a Kyosho diff from either a 7.5 or 777 and put it in Hyper 7 or 8. All are interchangeable. The cost for the gear from Kyosho America is $5.00:027:

Isn't that the one that needs more space between the two holders?

The only problem I have run into is that sometimes the spur gear can rub on the face of the diff housing. Some cars did it and some didn't. This is easily resolved by adding a small shim on the diff against the bearing so that it spaces it away from the housing. No big deal and the diff works perfect. I have done 4 cars this way (2-Hyper 7's, 1-hyper 8, 1- K-3)and none have any issues.

I'm still using mine, it works great no problems whatsoever.

Found it here in the netherlands.

Thanks, i am going to try it. Do you know if it fits a hotbodies cup? (which is the same as a savage)

Is there any reason why not to use stock spur gear? I was succesfull in using hardened pinions with no problems.

Artur

There isn't any problem with using hardened steel on hardened steel gears, but that setup comes with an unecessary cost and weight that can be achieved using a regular steel pinion and a plastic spur gear.

steel spur - 30g
plastic spur - 10g + alum. adapter ~10g

10g are so important?

$25.00+shipping for 10g pinion is not that bad.

Artur

I picked up the spur today at the LHS for 7$ not to bad.

It doesnt say what the pitch is??
Anybody have an idea what tooth pinion is need for an 8xl on 4s lipos??

I was referring to the all-plastic Kyosho spur gear. That would weigh a bit less than the steel spur gear. BTW, $25 is a lot for a person that gets that much money in a week :mad:1.

It's mod1. What vehicle are you using? This info is needed for knowing the ratio of the front/rear diffs.

Its a hyper 7 rtr.

Point taken, but it is all relative. One good pinion should last longer and allows ease of change in center differential department, you can switch between different diffs in no time (torsen/open/tight/loose/you name it).

Artur

Try to use a 14 to start. It should get you in the ballpark.

People are just giving suggestions here to help other people out. Why do you find it necessary to have a debate. If you have a suggestion, post it. You don't need to bait Metalman into an arguement by asking him a question and then debating his answer just to make your point. :mad:1

There is no arguement here...

It is nice to follow suggestions, but it is much better to understand them as well. There is nothing wrong with finding all positives and negatives in solving particular problem. It is difficult to come with good solution without proper input.

Artur

It is the manner in which you do it.

Just found this out tonight, The center spur gear diff adaptor from JT racing is a perfect fit for the ofna 51T spur gears. The Diff adaptor from JT racing is for a Hyper 7 center diff case.

Was it something they used on the Havok?

I went there site but dont find what you are refering to??
Do you have a link?? Thanks

The link below is to a site that sells the complete truggy conversion. Dont know if they have just the spur gear adaptor.
