Help - Newbie Confusion - Gear Shredding !!!

[FGNEWBIE]

Hi all,

I have now ventured into the realm of 1/5 with a standard FG Monster Truck, second hand of course i'm not loaded !!!

Only upgrade is metal pinion and drive gear.

My problem is the layshaft gear is rubbing on the engine case, very badly and has cut a nice groove.

There is no drive at high revs and it appears the diff gear is puching it into the rear of the engine case.

The Diff gear and layshaft gear have bad wear and I need to order replacements I am just unsure what else I should test for or buy before installing the spare parts.

I get the engine may need realigning but is it possible the layshaft is bent or the bearings are warped to cause this.

Am I right in ordering a 48t diff gear and an 18t layshaft gear ?

Any help most appreciated !!!

The lay shaft gear has 14 teeth.

Can you get a couple of pics up to show us??? Sounds like something may be bent or out of alignment


If it ain't broke, bash it till it is

as allan says on the monster truck its FG6046 and is a wide heavy duty 14T

gear should match up to a wide 48T diff gear

if you only have narrow gears then you may just have a marder with big

wheels on

if you don't have alloy engine mounts then i would suggest you invest in them

almost sounds like a bad bearing or a worn lay shaft
