| HD Worm gear issues...Still??
Helping a buddy try to put HD worms in his LNC, couldnt spin the pinion by hand or pliers. After many different shim combination s and even trying it without the spool, the pinion was still extremely tight in the housing... I then measured the length (from bearing seat to bearing seat) of the pinion to find out the HD pinion is almost a full MM longer than the original... WTF Losi ?!?!?! Anyone else have this problem ??? |

Tried the ones it came with, the originals and none to no avail... Even with no shims and no spool it still would bind when the case bolts where tightened... It seems the pinion is just to long between bearing seats... |

Yep... I'm sure Losi knows...? I sent a set I had ordered back to them. Still no word. I put Dlux in the rear, also ordered another chromo for the front. My HD is showing pretty good wear only after two comps and light practicing...

this is a stupid question, but are the HD's the worms or the spools? Or, both? If it's just the worms and they run on the regular spools, i'm going to say screw it and get the cromo units from dlux.

[ WTF Losi ?!?!?!???[/QUOTE] First off bub it's not LOSi who makes the gears, it's a seperate machining company and it's not like they pre-run each and every gears before they sell them to see if their perfect..if you have an issue try nicely asking losi top help you out and loose the attitude that it's somehow their fault, thats my advice. |

You can say it's not there fault all day long but they choose who makes there stuff. |

Oh by the way, hd's were made to use less shims, so it will be longer... I just pulled the calipers out, the hd's are 30 thousandths longer (shim seat to shim seat) which is 3/4 of a mm longer, so they are probably machined correctly, i think you have problems else where. |

I tried new bearings and housings with mine and didn't help with the HD's. If I still had my bad set, I would measure them both and give a comparison.

The stock worm spun freely before with its original 6 (I think) shims, and worked perfect after we gave up on the HD worm... I suppose you could...But really, shouldnt it just fit like its supposed to | ||

| same problem
I just got a set of HD's and they bind up as soon as I put the housing together. At first I thought the bearing was bad but it seems fine. Not sure what the problem is still though. I read the post but something doesnt seem right.

Installed mine two nights ago. The front was a bit rough but still spun, installing the rear it was a different story, they were smooth as butter. Oh well I guess the fronts will have to wear in. Ryan |
