darren f Posted May 18, 2019 Share Posted May 18, 2019 As Phase 2 of my R300K 'recommissioning', I need to sort a timing belt replacement (the existing is 5 years old). To my shame I've not done it myself before, and reading up it seems the perceived wisdom is to change the tensioner at the same time? A quick removal of the covers turned up the following:- I'm assuming I have the dreaded automatic belt tensioner there? There is lots of noise in historic posts about these being c**p but I take it that this only really becomes an issue with mega-bhp, rev-happy, full-on track-day or race applications?It's been fine up to now (road plus occasional track days on a standard 160bhp engine) so I have kind of answered my own question, but for research purposes,at what point does the need for the manual tensioner (which seems to be an engine out and drill / tap new holes job) come into play?

Member Jonathan Kay Posted May 18, 2019 Member Share Posted May 18, 2019 Are you planning to change the water pump while you're down there?Jonathan Link to comment Share on other sites More sharing options...
darren f Posted May 18, 2019 Author Share Posted May 18, 2019 A question promotes another question !It is on my radar, but there has been no issues with it thus far. However despite this I assume the best practice answer would be "yes"? And that means sourcing a new pump with metal impellers and an evap chamber (... proving I've read up on the subject!). Anyone know of a supplier and part number? Edit- Apologies, didn't realise you'd done a link- I'll read through and find a suitable 'supply chain partner' or 'supplier' as they used to be known.

oilyhands Posted May 18, 2019 Share Posted May 18, 2019 If you have any difficulty in sourcing the parts, I keep the correct belt, tensioner and metal impellor evap chambered pumps in stock.It’s worth noting that the surface of the tensioner roller is very uneven and this is not good for the belt, I always linish them so that they are flat and properly round and then repolish the surface before use.Oily Link to comment Share on other sites More sharing options...
