    Hi ,

    My mechanic recently performed a timing belt service . I replaced the factory Tensioner Bearings w/ Hill Engineering Bearings. According to members of Ferrarichat , its finest bearing tensioner available and much better than the standard SKF supplied bearing from Ferrari . My question is it mandatory to replace a Hill Eng. bearing everytime the timing belt is replaced. In one forum they said it should be replaced every other timing belt change . So whats the consensus regarding this matter.

    Thanks in advance,

    Luigi

    I changed mine once in 20 years-the ferrari one is fine. Every 2nd belt change is overkill

    My guess is no depending on miles. Realistically only a few of us would ever do a 30k because we actually put that many miles on a car. A tensioner bearing on a Honda or pick any other car is good for 7 years and 90k miles. How many people change those in time?
    Many mechanics who do belt services on mere ordinary cars fail to change the bearings at all! Some will charge extra if you insist.
    My trusty but boring Volvo 850 wagon was tormenting me with its unwavering reliability. Loved it for how reliable it was, but was also so bored with it. It was consuming oil though. So why do a belt job? I'm driving this car into the ground anyways.
    Technically it needed a valve job anyways, most likely if the belt failed that's all that would be damaged anyhow. That damn thing went to 165k before i could no longer stand it. Gave it to a friend who fell on hard times still running fine but going thru some oil.
    Always say ill drive them into the ground, but had to scratch that itch and try something new!

    Tensioner bearings are so inexpensive relative to the cost of blowing up a motor which is why they are replaced. Like Remo said in Casino, "Why take a chance?"

    Good point.
    My counter would be and this applies to many electro/ mechanical parts. Most of these parts fail when new or very old.

    So could be delivered defective. Now one might say " yes but a quick spin to see that all is well"
    But have seen bearings fine in that regard then fail under load.
    Food for thought.
    If you have bearings 3 to 5 years old of a known high quality ( Hill Engineering) that have no obvious signs of leak, damage and it's been the typical 2 to 5k in miles since new well....

    Thanks guys for your replies . In my car the last time the belt tensioner was replaced was 10 years ago . We check out the old bearing and according to my mechanic , even that if the bearing looks ok might as well replace it as a precaution . Accdg. to some forums the quality of the new SKF bearing are in question & are made in China .

    Too bad SKF is ruining its reputation, used to be among the best bearing companies in the world. Hill bearings should be good for two or three belt changes, other bearings like the water pump idler are more likely to fail and often overlooked.

    Some non-important information. SKF, Swedish Ball-bearing Company, is 110 years old and today situated in 100 countries. I do not know where the production plants are but I doubt that it should matter in which country they are made. Quality assurance should guarantee same quality regardless of country. If I remeber my industrial history correct, they started Volvo!

    You can be sure that hill engineering are not making the bearing but just buying them in, probably from SKF anyway.

    Agreed they are. The issue is SKF has had problems with shady copycats using inferior bearings labeled as SKF and counterfeiting even the boxes.

    Thats an expensive lesson Afterburner, prior to purchasing the Hill Engineering tensioner bearings , I was thinking of sourcing SKF bearings here in the Philippines , because SKF bearings because they have importers/ distributor in our country . But due to my busy schedule I ordered the Hill Bearings on line. Who knows If Ive source it locally most probably it would be a knock off.

    Audioresearch yes it was rather expensive, and only after 15'000km.
    I bought the bearings from a reputable distributor in the UK...
    Obviously, SKF isn't totally in control of their supply chain.
    And I didn't notice. Always checking now. The replacement bearing from SKF lasted 85'000km.
    That seems more reasonable.

    I can't tell from your pictures but can these bearings be replaced without removing the front cover? I have to do belts and tensioners this winter and thought maybe I should replace these also. My engine is at about 35k

    Yes, you can replace the front bearings using the following puller:

    The rear bearings in the engine block can only be replaced by removing the front cover but they seem less critical as they are in a permanent oil bath.
