Gixer1460 Posted January 29, 2022 Share Posted January 29, 2022 Sort of depends on use really! If it's a low mileage, been stored in a barn for 30 years then they may be ok but rubber compounds + oil + heat + age = inbuilt obsolescence! Look for hardened and cracked rubbing surfaces and if in doubt, chuck it out! as a broken tensioner guide will make a mess of any engine! Quote Link to comment
Kevref Posted January 29, 2022 Author Share Posted January 29, 2022 Would the same apply to any NOS guides advertised ? as in becoming brittle etc Quote Link to comment
wraith Posted January 29, 2022 Share Posted January 29, 2022 If you have the spare money, for piece of mind get some new OEM ones from Robinson's I would think most second hand ones will be showing there age Quote Link to comment

Finding them is the problem! 1 hour ago, wraith said: If you have the spare money, for piece of mind get some new OEM ones from Robinson's Good luck with that as both listed as order / out of stock and the rear one is £350+ so big OUCH!
