Thank you wrisrpin and trusty220,
Yes, there is a good bit of sideways movement as you can see from the photos.
I’ll investigate the cause and report back.
Thanks for pointing me in the right direction.

Hi Folks,

thankfully other then normal maintenance, I have had no problems with my Motor Triple for the last 2 years.

Now I have an issue which I am struggling to figure out. Any advice would be appreciated.

When cutting, it keeps throwing the vee belt off for the rear (middle cylinder) I replaced the vee belt as it was cracked and worn.

With the new belt on I thought I would be sorted but unfortunalely not. It is still throwing the belt off.

If the machine is stationary and I engage the cylinders, all three will spin fine but once I start driving, the belt will come off within 100 meters.

Any ideas?

Thanks in advance.

Relined and springs replaced. Now working perfectly.
Plenty of grease applied and it shouldn’t seize again.
Thank you for all the guidance, much appreciated.

Thank you for all the help and advice.

I found a Ransomes agent near Dublin which is the closest for me. Parts come from the UK but I can collect them easily from their shop. They can also arrange the repair of the lining. A good find I think.

I go on holidays for 2 weeks tomorrow so this job has to be postponed until I return.

I’ll put up a post when it’s back together and fingers crossed it will all work out.

Thanks for the encouragement, I finally got it off but it fought me right to the end.

I got another socket snug inside the box section so that made the puller a lot stronger.

To finally get it moving I had to put a flat head screwdriver at 12, 3, 6 & 9 O’Clock to separate the plate slightly. Then thread the central bolt back in and smack it a good 10 times. It moved a few mm from the hammering. After that, screwdrivers out and puller reattached and it started to creep off.

The shaft has a small bit of corrosion but nothing that should have made it such a struggle. It will get a good clean and grease before going back on.

I can see two problems with the clutch. The right hand spring is very loose and both springs will need to be replaced. Also, the lining (if that’s what it’s called) has worn/corroded/broken.

I’m inclined to think the spring is what was causing the problem and not the lining. There were no broken bits of lining inside so I don’t think it’s something that has happened recently,

Any thoughts would be appreciated.

Thanks so much for the detailed message trusty220. Nothing beats hands on experience.

Apart from removing the two stud nuts, I think I was heading in the right direction but just to be sure, would you mind having a look at the attached photo and let me know if this is the set up you were describing.

I refitted the 2 stud nuts, attached the puller and started to wind it on using the partially threaded central bolt to push against. The socket is being used as a spacer to avoid the studs.

The 50mm box section puller is starting to bend under pressure but the clutch has not moved. I will fit another socket or similar in to the box section for additional strength.

I think I’m almost there and if the puller set up is correct I’ll keep going and hopefully it will let go.

Thank you for your reply wristpin and for the manual.

I’m going to have another go at it this evening. Additional persuasion is probably what is required, it probably hasn’t been off in 20 years, if ever.

Getting the plate off will be a victory in itself irrespective of what’s going on behind it.

Thanks again, I’ll update when I make progress.
