Ransomes roller rescue

Recommended Posts

Was recently given a Marquis 51 in a fairly sorry state including the two rear roller section seized to the shaft ( no diff action ) and much of the "tread " worn off them.

The recovery process involved dunking the whole roller in diesel, "easing" it a bit at a time with more soaks in diesel between sessions , a session under a farmer friend's press and finally recutting the grooves with an angle grinder !

When you separated the roller sections did you find wear in the inner bearing of the roller section that still had half of its grooves unworn? If not it is a bit odd that the roller has worn in the way that it has.

No appreciable wear to either the shaft or the bearing areas of the rollers. Think that the excessive outer wear resulted from the roller being seized ( no diff action) and being "skid steered".
The machine was bought by a private owner at the "closing down sale" at Wye Agricultural College for £20, where, with their extensive grounds it had a hard life, and it was only when they got it home that the extent of its issues - seized roller and smokey engine - were realised!
It was given to me together with another Marquis as payment for "services rendered" - long and complicated story, but I'm quite happy with the deal!

The Honda engined machine also had its issues despite bills for over £1100 (yes, you read that right) in the last six months!
Problems included collapsed front roller bearings, seized/worn out traction clutch push rod, sticky, incorrectly set up main clutch , four inch crack in the engine platform and strangely enough considering that new cylinder bearings had been fitted, unequal length reaction springs on the cutter unit!
All fixable with knowledge, attention to detail and a bit of graft.
The collapsed roller bearings were a bit tricky as the outer races were buried deep in the roller end caps and required the old trick of running a bead of weld around the inside of each race which when cooled shrinks and loosens race. A sharp tap and they fell out.

Have tried to upload some images but although I succeeded yesterday, today it just sits buffering. The only thing that's changed is an upgrade to iOS8. Hope that it's not that as it will mean a bug fix from Apple!

Going to email the images from the iPad to the PC and see if I can post them from there.

 

Looks like that has worked!
