g/box lube - 11.28.2009, 09:31 AM

hi all...sorry guys i did not make myself clear, i have not just poured this thick lube in the box, i have just coated the cogs on all meeting faces with a few drops of the lube as thinner oil will not stay in the box.

rivermaxx, i agree with the rear pinion weakness but then again this truck is not designed for 5-6hp, the weakness is because the rear crown wheel and pinion are not cut correctly, if you magnify the rear pinion you will see the contact marks are on the outside edge only so the tourqe is taken by just a few mm of tooth, i am still using my original front pinion but my rear has been changed out for the newer 3906 due to failure. i weighed my truck and its 11.3lb not too bad seeing as its extended by 40mm . and yer there is alot of free play in the bearing even when they are new.

redshift, yes when you reduce the gearing you amplify the torque, thats how come i smash cogs and you dont, the problem i have is with the smaller 20 tooth cog. but seeing as i was splashing out on gear cutters, for another £40.00 i could make the 31 and 36 tooth cogs from steel as well. i dont crawl with my truck as id loose the will to live at that speed but i climb the biggest hill i can find and my truck is geared down with the spur so 1st gear is good to climb. those ti gears look wicked tho, i allways dip the throttle when i change gear to prevent damage, it tells you to do that in the manual.
