ON THE COUCH
I've been getting fed up with the slop that keeps developing between the rear arm pivot pins, and the rear alloy plate they fit into, which translates into a lot of "for and aft" movement at the rear wheel.
The pin seems to wear fairly quick, and the hole seems to ovalise quite quick too causing a really sloppy fit between the two.
So i removed the plate and drilled the holes out to 10mm. I fitted into these holes some bearings I found on Ebay (6x10x3mm flanged, £5 for 5) with the flange fitted in board (next to the arm). As the pivot pin is 6mm diameter, it is a perfect fit inside the bearing.
Once everything is back in place, a 6mm washer fitted onto the pin before the E clip makes things nice and neat !!
All the slop is gone and the arm is now running on bearings! Very pleased !:clown::clown:

That's a great tip right there all the new guy's to HPI,KM,Rovan,Sheng Qi

You can also try brass...I am having a guy make a brass
sheath for front and back outer and inner pins. Here in a week
or so.

Yeh I was thinkin about something like that but the bearing mod just seemed so simple and didnt take long at all. But keep us posted on how yours bears up.
 
very good mod, mate the play in the rear arms on my baja is quite bad just got new back plate but they don,t last long before the hole in them ovals and the play start again, good mod and cheap as chips.

Wont the hinge pins eventually hammer out the bushings being that thier made of brass?

I wouldn't think they would be hammered out any more then the bearing but they will wear where the bearing will not.
But, This brings a thought to mind.
A bushing is made and created to wear a bearing is not. The bushing may allow wear to it and not the piece its in. The bearing may transfer the wear to the alloy piece and the bearing make the hole bigger.
Or
The bearing may allow the rod to move more then the bushing and the stress and wear from the rubbing rod may never happen again.

Not sure, will be great to see how this all works out.
Either way I'm going to try out the idea.. ;)
 
The bearing will soon seize up due to wet conditions, general shite & lack of rotation but so long as you spray it with WD or spray grease when you have done your clean down there shouldnt be any issues. This will lube the inside of the bearing where the shaft sits and should keep wear to a minimum & give you years of life out of em :cool2: At the end of the day it is being used as a locating bush to give a better fit on the shaft so whether it seizes or not is irrelevent. Great idea mate :cool2:
