8ight conversion

problem
I'm instslling mikes motormount in the 8 and realized the center diff has to be turned backwards (from normal) so the spur gear reaches the pinion...is this correct

the center diff can run properly in the backwards position?

[Semi Pro]

yep the center diff can run in any position

Yep, center diff has to be turned around.

Is that with ALL the Eight conversions?

It has to be run backwards, there is no motor out there with a shaft that long to run it around the correct way

lol..I found that out the hard way.....had the new motormount installed real nice used blue locktight and went to put the motor on and said.....somethings wrong.......but its not just a matter of turning the diff around...you have to take the diff apart to switch the drive cups and bearing around also because they use differant size bearings and the motormount will only work with a certain one

I had the same thing when using the losi conversion. I thought maybe the guy I bought it from used aftermarket bearings, or changed something....I guess thats how it goes. Weird, it wasnt in the losi directions, so I thought it was just something on mine.

....sorry I didnt give you the heads up.

THIS IS THE CAR WHEN I RECEIVED IT

Hmm, thats weird. All I did on mine is turn the diff 180*, and it fit right into the motor mount and diff bulk...

well on mine with mikes losi 8 motor mount.......it has a groove that holds the bearing that over the drive cup shaft...well on my center diff the front drive cup had a larger bearing than the rear drive cup......so when I turned the diff 180deg the bearing was too large to fit in the groove on mikes motor mount...hence having to take the diff apart and switch the bearings.......maybe the guy I bought this eight from had different size bearings for some reason

anyway tomorrow I will post pics of this conversion

Nice conversion! With a 1512 2.5d I'd go with 50k or lighter. I found 100k to be the magic number with my 1515 1y. anything lighter and it unloaded too hard, anything heavier and it was a wheely machine. The 1512 makes less torque so lighter oil in the 30-50k range should suit you well.

Thanks Dicky but please give me your suggestion for front, center and rear diff oil's....i'm new

I run 7.5'ish (a mixture of 10 and 5) in the front of my Mugen and 5k in the rear. As more of a basher style driver I find this perfect for me. I live by the go into the corner hard and use power to pull me around it method of getting around the track.

If I were a clean line style driver I would go a little lighter, 5-7k front and 3k rear. your driving style will be a determining factor in what oil you want. We all (you, me, and hoov) need to finda common sunday to hit up traktopia ! and one of these sundays you will have to drive down to the yamato track.

so I take it that means the 50k goes in the center?...right now I only have 3k in the center...its all I have at the moment
