I do have an issue/question, when I build up the gear diff it seems notchy and tight like I'm running thick lube but I'm only running 1000wgt. Are there any tricks you guys are using to get the diff smooth? Is there something I need to look out for when building the diff? Thanks in advance...
1. Before screwing of left and right side of diff plese check the rotation of ST07 outrives installed into AT23 and AT24 with the all inner bearings, O-rings and ST20. ST07 should rotate free with some light tension due to O-rings. It is very useful to add the drop of oil on the O-rings or ST07 on this step.
2. Assemble the diff without G06 and G05 gears but with P17 Cross installed. ST07 should rotate the same free after such assembling.
Otherwise something is wrong with O-rings, B85 or ST20 installing.
3. Add G05 and G06 gears and check the diff again without diff oil.
Please be careful at the final stage of screwing of AT23 and AT24 with all inner gears installed. You can easy damage the plastic gears in case of wrong alignment of the gears.
ST07 should rotate same free after such assembling.
Otherwise check the gears ( maybe sand the big gears a bit ).
4. Disassemble the diff, add diff oil and assemble it again with all precautions.
Please don't fill too much oil inside our geardiff.
The enough amount of air should be inside.
