Changing rear wheel on Max IV

[Drooper]

Hi

I've just fitted a brand new gear box to my Max IV and thought that I was ready to roll, but have now discovered the bearings on the drive sprocket on the (starboard side, if it were a boat) rear wheel have collapsed.

Can anyone point me to a thread on the easiest method of removal?

Dealt with RI to get the new gearbox shipped here to England and was very impressed with their efficient and friendly service, brilliant.

I will shortly be putting my old T20 up for sale. There isn't a market here in the UK so it will probably end up across the pond. Any ideas of a good place to advertise it?

The manuals section on this site has the info listed under MAX. If it is a spline axle type you can have set screws or snaprings holding the rear sprockets. Serial number will help identifying age. Lots of help available on this site. Good luck

Look in the how-to section of the site: How to replace Bearings

As for the T20 that you will be selling, advertise it here in the Parts for Sale forum by starting a new thread there when you're ready to sell.

Thanks for the advice on removing the rear axle. I have finally recovered my stranded Max from the marsh. Having thrown a drive chain that was stuck solid between the main drive sprocket and rear chassis cross member, and with nothing capable of getting near to it, my solution was to spend a couple of weeks raising the water levels enough to float the Max back to the trailer, a distance of about 1/2 mile!

Have found the problem, whoever fitted the axle last time failed to put any spacers or shims between the drive sprocket assembly and circlips, giving me approx 15mm of lateral play.

My solution is to turn up some locking collars to go either side of the sprocket assembly and do away with the circlips and shims. I think that this method will be easier to align the sprocket with the gearbox output drive.

Has anyone done this, if so was it successful? Does anyone see any reason not to try this?
