Pinions for a B44 - Which brands can I use?

[AC199]

I'm looking to change the gearing on my B44, and am looking for a couple of new pinions, but am very confused as to what brands I can use on the car.

I cant seem to find any Associated ones, so am being left a little stumped, was hoping for some help from you guys.

I pretty much always buy from MB Models or DMS, if that helps in anyways...

Thanks for any help

Hi,

Any of the normal size (ie not long boss) 48dp pinions will fit the B44.

is that the same for the b4.1?


I'm sort of in the same situation.

Yep, all the Team Associated electric 1/10th cars take the same sort of pinion.

As stated that's 48dp. Any decent shop will be able to help with that.

Chris,

Pete has pinions, he stocks RW pinions. What are you looking to change it to?

As a guide at york: I run a 10.5T with an 84T spur and 22T pinion.
Somewhere bigger i run 8.5T 84T spur and 23T pinion. I did run that at york but found it wouldn't get to full speed on the straight, so I should've knocked it down a couple of teeth on the pinion. But I couldn't be bothered .

Trying to get the overall ratio down to about 6-6.5ish. Currently I'm running 7.5 final with 81 spur and a 27 pinion, but I'm spinning the wheels a little, and locking up a lot on braking, plus I'm gonna be running 4wd mod this weekend with my 17.5 for giggles and thus will need to be a little faster.

I've been advised to go to 72 spur and 27 pinion which will give me a final drive of 6.67, but I cant find a 72 spur anywhere, so am going to a 75 spur and a 29/30 pinion...

I've managed to source them from MB, will go and pick them up later on this week.

Now all I have to do is work out how to change my spur, back to the manual we go...

6.67 sounds overall I think is going to be over geared and will cook your motor. My recommendation is 81T spur and a 26/27T pinion giving around 8ish overall. My lad last season ran a D4 with a 20T motor 80T spur and 24/25T pinion. Overall ratio was about 8.
Remember Yoda's advice...."over gear if you must, toast your motor will be. Hmmm"

[AC199]

The motor is setup with a thermal cutoff, and the manual for the motor says to not exceed an overall ratio of 6, so am keeping a little leeway between my choice and the overall.

We'll see what happens, if it gets too hot, it'll just thermal off anyways... hopefully...
