| Post subject: | Mini timing belts |
I sold my 2nd last spare Dayco Isoran timing belt to Ben Tebbutt today. These things are becoming rocking horse droppings, unless you want a loose Chinese made one. If anybody knows an Oz source for these Daycos, let me know. MiniMania has their Gates Kevlar ones @ US$120 ea + post, that may be the only source of decent belts left... Dayco and Gates here seem to know nothing of these 052R190 belts.

Is there a belt available in a similar size and then run an idler pulley? |

They are only 52 teeth x 3/8 pitch. Neither Dayco or Gates list a 52 tooth belt in 3/8 pitch, although both make them. There is a Mini kit available in UK now which has an idler pulley, but it uses a 52T belt too. No room on a Mini to use a longer one. http://www.shengineering.co.uk/sh/conte ... g-belt-kit These were using Dayco's belt but they are having trouble getting them. Somebody has now bought exclusive rights. The Gates Kevlar belt (Japanese) is supplied only to Mini Mania in USA. |

I recently fitted a new belt bought from Lindsay Siebler (Minis Plus) in Melbourne. It was $48.50 posted to Adelaide. Its a Chinese one but was definitely not a loose fit (about the same 'tightness' as the 20 year old Pirelli one I replaced), but then it wasn't a struggle to put it on either. I'm happy with it.

I'm curious why they only guarantee 40k? Is it purely because there is no tensioner to take up any slack or is it simply at the end of it's life? A large majority of the cars out there with timing belts specify 100k or 150k although i suppose there are some out there which say 60k (holden astra/vectra etc i think) |

So, it goes around a zillion times more often than a twincam one does. Lack of a tensioner probably helps life- as you are not bending the belt on its back. BTW MiniMania USA reckon they are only good for 20,000 miles and their Kevlar race ones 50,000. And this is expected life, NO guarantees. |

They do last longer than that. I have a Pirelli one here that I did 40,000 miles on. It is unmarked, but I wouldn't put it back and push my luck. You need to be very careful with the pulley teeth when fitting and removing. If they get burred anywhere they chew the belt up, muy pronto. These belts seldom break in my experience (20+ years of running Fiat ones, same belt type only MUCH longer). The outer part is reinforced with fibreglass or kevlar. They last until the polyester coating on the teeth wears through. Then, there is no reinforcement in/on the tooth, it is just a block of rubber. So whizzzzz... and the bottom pulley takes about 10 or more teeth out and belt no worky.

I love timing belt failures. If it wasn't for them, I wouldn't have got a cheap replacement transmission for our Volvo V70 T5. Just waiting for a Renault Scenic's timing belt to snap now... Back on topic: Are they quieter? What's the main benefit? |

Main benefits are on a race motor. They absorb less power and don't stretch like a chain, so the valve and ign timing stay correct. You don't need to advance the cam timing to allow for chain stretch. With a Pulsar dizzy & a belt drive kit, my ign timing stayed correct for 2+ years road use. |
