I am in the market for 4 speed jerico. and i just bought a used one on line

and seller claim is been rebuild and store as spare

and he sent me few pic of mt

here is two of them. you can see there is slighly chip on dog gear ? is this normal ?

i understand when you change gear in dog box it will wear out the dog ring

but i dont know how bad is need to be rebuild ?

 is this one the case need to change ?

thanks for your time

I don't see chips on the dog gear but rather the face plate. I don't think those small chips will cause any issue with the performance of the transmission. Here is a link regarding shifting advice from Hewland.

FWIW, I installed a similar dog box last year and very much enjoy the reliability versus the OEM FD 5-speed.:icon_tup:

That looks clean to me from what I can see in the pics. What model is that trans?

the pictures show a very nice transmission. the edge of the dogs do not look bad at all, this is normal wear and should not be any problem. wish i had pictures of the race trans I had, them dogs look nice. mine were beat off in the corners and it still worked good, high rev pull hard and still made the gear. That trans was in a 65 nova alki car making 500hp it never broke or missed a shift............just sayin

Just call sevens only

Their package won't work for this jerico

Their kit is for reversion 4 but mine is old style
Reversion 2 ( I thought all jerico are the same)

And they told me to get crysler input shaft if
Plan to use their kit ? The reason is chey not long
Enought

Any one have better solution I can find
