TOPIC:

I was just thinking how the idler gear is mounted in the casing with an 18T pinion...
Isn't it on crooked when the hole in the gearbox plate is at a different position?

Sure would be nice if I could have a real look at some of the cars.
And a dealer's guide would also come in very handy.

I know this website its called tamiyabase they have some nice copies of T manuals, if you have a look at the M38 lwb and wheeler manual at step 15 you can see and compare how the idler gear fits in.

I've been looking at 65 manuals so far of course.
It doesn't show the inside of the casing though...


But a Tamiya peculiar! I noticed I have two different manuals for the 58035.
The second one I just looked at, shows the gearbox assembly completely mirrored...
I can see the second mounting hole in the gearcase there.

yep top picture is M38 lwb and the lower one the M38 swb right, now compare the step in the top picture with the one in the wheeler manual, you should be able to see a 'small' offset.

Okay, so the second pic is from the swb manual...
I did notice the offset on the gear plates though.
Just the side of the gearcase looked exactly the same in the 58035 lwb manual compared to the others...


Now I see not exactly either...

58023 Holiday Buggy
58024 Sand Rover

15 tooth & 18 tooth .8 module

Taken from Robinson Racing web list; "Note: 32 pitch and .8 module gears can be used together with no adverse affects such as increased noise or increased wear. The difference is that .8 module gears have a slightly larger outside diameter per tooth, roughly .00027 of an inch."

And I have found out that .8 mod actually equals 31.75 pitch.


Hope this helps.

Thanks! Will be added to the list.

For substitute for the 18t Hornet pinion, you can use Traxxas 3948 pinion, which is steel..

Wouldn't it be nice also to have infos about the diff/idle/counter/pulley gears, the inner and outer ratio of the gear box and the diameter of the wheels? I where searching yesterday about my moded 58058. The BF/MB (instead of Frog/Brat) has a 52tooth Counter gear, a inner gear with 17t and the diff has about 48t.

I'll do a couple of the direct drive cars then.
