Make sure you are using the steel layshaft. The end with the flat piece sticking up is on the screw side (battery side). Use a small screw driver to hold the layshaft from spinning while u wrench down on that single screw.
yes i have the steel layshaft in both cars,will place an order with tower for these screws & when i recieve them i will swap the layshafts over as i have the flat piece on the motor side
once again thanks for the info

one last suggestion / recommendation - when i've run modified w/ the TOP Photon i initially had problems stripping spur gears. this was due to the fact that my kimbrough gears were not perfectly round within the layshaft. after stripping out about 5 108T gears I finally had some friends point out the best way to check gear mesh:

#1 set your gear mesh. tighten the motor screws fully
#2 rotate the spur gear a 1/4 turn and check the mesh. continue to rotate the spur until you go full circle.
#3 you may notice that eventually there is a section of the spur gear that is looser than the others -- focus on that part!
#4 once you find the loose part of the gear mesh, re-adjust the gear mesh here (and here only)
#5 repeat steps 2-4 if necessary

Anyone using the alloy camber links? I'm assuming you have threadlocked the grub screw?

yep thats how i set the mesh also,been doing it that way for years (i use 48 pitch spurs, 64 pitch is not so widely used here in aus)
also in your earlier post you said to put the single screw in the layshaft from the battery side,is that purely because of the fan on the motor side or was there another reason ???

Yes.. it doesn't matter which side you use... just don't use both screws.

Hmm, I was set to buy a Yoko gear diff with some other parts I needed soon, only to find out there is like no stock, with none expected anytime soon...

So looks like I may have to buy the Spec-R to replace my failing Micro-Pro.

Well it throws a bit if a tweak at the bulkheads that hold the layshaft. Even with this tweak Jason Schreffler won the Super Stock at the 2010 Snowbirds.

rc-race-and-drift-japan has the Yokomo gear diff and oils in stock. Took about a week for my last order to get to the US.

They have 1. I was just about to place an order for a set... I assume it is worth the wait to get the real BD5 gear diffs vs the spec-r. I don't think I will get a chance to racing for another month, so waiting isn't a big deal.

Yup, I read somewhere that ALL spur gears are not completely round, so I either do it the aforementioned way. Or, and this ALWAYS WORKS for any pitch gear, take one tooth bigger-snug it up all the way, tighten motor. Then take that pinion off and put on 1 tooth smaller---perfect mesh every single time.
