Hi,

i have an R&D 6 speed straight-cut dogbox fitted in my EsCos.

i bought it new 3 years ago.
and since then i have broken it every year.

this time the 4th gear go away. but when we opened the box, i can see some small (2mmx2mm) and same bigger (4mmx4mm) damages on the surfaces of most gears.
some peaople tell me, that this is called "beetings". and thats exactly like it look for,

i have no oil cooling fitted. i think i need that. because of same long rides on the autobahn.


but whats also wrong ?


is it correct that A.G. in his focus Cossi with 800++hp is using the same box ????


i do approx 20 Quatermile runs per year and some laps on the hhr and the nüring.
i do 10.000km/ year complete.
I have no semislicks. only normal yokohama avs road tyres.
the car is doing r.a. 720hp/600lb.ft.

where can i get the parts for rebuild or where can i bring the box to do that ?
is there a possibility to strenghten the gears, like special material or producing methods ?

Unluckily, i have no pics of the "beetings" know for upload !

thx for help and answer

 

You could always have the gearbox frozen, as this will massively increase it's resistance to fatigue.
I've had this done in the past on certain bits but it doesn't seem to be popular here(uk).

sorry, my last post based on completely missunderstanding.

i can get the gearbox internals frozen to make them more stronger ???

how or where can i do that ?

what abaut the A. Gallager box ? it cannot be the same, or ?

 

I've no idea about the other box you mention, but will try to find out for you.
Cryogenic freezing does indeed massively improve things, there is a firm in the UK called FROZEN SOLID, that do this, it's not cheap but I suppose neither are box rebuilds.

Andrew Gallager is using the R&D 6 speed straightcut box in his 800++hp powerd focus cossi. and he do a lot of trackrace and quaters. and it seems without probs. ????
