In my opinion all parts are servicable or repairable if buyer deemed they required repair. Anyone interested should ideally see parts first to assure themselves as to suitability for use. However I will gladly provide further photos and details as required. Would post oil cooler but other parts require collection really due to weight. Could meet part way if not huge distance involved.
I think that there is a tensioner in amongst all the various bits and bobs. Not sure of the condition of it from memory but will post something here when I get a chance to route through the box again to check. There are quite a few other things included in the sale that are not listed in the previous discussion or shown in the pictures. A good buy for someone I think.
