I'm giving the ride on mower its winter service and have discovered a belt tensioner with a seized bearing. Google is not being very helpful in finding a replacement. Can anyone suggest a source of generic tensioner pulleys, or even a Mountfield parts site that makes sense.
The damn thing is riveted together with the bearing sandwiched in the middle so just replacing the bearing is not that simple.

Generally any Mountfield dealer will be able to get you the correct spare - even if it means a complete subassembly.
Several other sorts on eBay
Indeed I can order them from the local mower parts place, at 42 quid each!!!

You could buy a bearing, an angle grinder, and a pop riveter for that and still have change!
That's a more sensible price, but my machine isn't listed.

When I changed my car's timing belt I also changed the tensioner (came in a kit). Some garages may have some old ones they don't want,
I decided to take the plunge and drill out the rivets holding the two halves together, no problem. I have now ordered new bearings from simplybearings.co.uk Total cost £8.50 for two better quality SKF bearings than the Koyo ones that came out. Rummaging around in the workshop I've found some aluminium rivets (traditional ones not pop rivets) that are slightly larger dia than the ones I drilled out and some small cheese headed screws with nuts that are slightly smaller than the old rivets. I have screws of the same size as the old rivets but the heads and nuts are too big to fit in the channel around the pulley.
Perhaps I will use 4 screws and 4 rivets in place of the original 8 rivets in each! BTW I discovered a second tensioner with the bearing in almost as bad a condition as the first.

This is one of the problem pulleys.
