Pulley modification...

[Ty Korrigan]

975hrs on our 2012 Quadchip.

As I was changing the bearings I noticed the tensioner pulley was wobbling around.

The bearings had long dried out and siezed so the bearing shell was turning within the pulley wearing the softer alloy. Still tight on the pulley shaft though.

New pulley is 1. 'tres cher' 2. A unique part to G.M so not able to be sourced by any local suppliers.

So I asked our local friendly engineering firm for advice and this is what they did for 135euros inc vat. I supplied the bearings.

Remember what happened when you "saved money" on the grinder belts?

Looks as good as the genuine article.....

No, the specialist industrial belt supplier sold us the wrong belt and being F-ing French insisted that the belt was the genuine article and that was that.

20hours later they got proved wrong...

Still, the new one is on and the machine is busy re-gaining lost ground.

I have a friend here, a retired manufacturing line technician who fitted the belt for me for a bottle of un-commonly good Scotch.

What I'd like to do now is replace the drive wheels for semi-ag versions.

Might help stop it getting stuck on it's own shadow...

Funnily enough, Rayco are doing a 4wd conversion kit for my one, I've made enquiries about price and ease of fitting.

 

Like yours it's surprising pathetic on wet grassy slopes.

 

It's entirely possible Bandit might be doing the same thing.

The 4012 had many odd design flaws.

Placing sensitive electronic equipement in an uninsulated steel box without any attempt to vibration or damp proof it.

3 options of controling the machine but none which share the same toggle switch configeration making switching over controls a struggle.

Uber-pants on loose chip, wet grass and gradients.

Having a radiator placed where it can suck up chip dust and also block the view of the stump if using the toggle switches in an emergency.

A build that although tough and well finished has many traps for dirt making cleaning more of a chore than it should be.

Original bearings that purge grease into the main drive belt housing requiring weekly scooping out of the filthy mess.

The turning circle of Plutos orbit...

American standard sized fittings when it is sold into the European market.

FFS wouldn't hurt to make the bits metric for us would it?
