Timing belt tensioner replacement?

Post by jtornese »



I got new timing belts and tensioners, and have been studying the how to article relating to changing the timing belts, in preparation. The article doesn't actually cover replacing the tensioners, so I wanted to check ahead of time if there is anything to know before I unbolt them?

Didn't notice anything particularly unusual about them when I did my belts a few years ago. I believe the manual says to inspect them at 100k. I replaced mine but probably didn't need to. Was concerned about them being so old and they were sealed. Seemed to spin fine and didn't notice any funny noises. They were expensive for OEMs (then again most OEM stuff is!) Thought I saw a diy article for rebuilding them if needed. I guess I replaced mine for peace of mind even though it probably wasn't needed. :D

Replaced the timing belt idlers on my '85 LTD a year ago as part of my restore/refurbish/maintenance of the bike. The timing belt tensioner is the same for the 1500 and 1200. You may have to loosen the tensioners to get the new belts on. Kept the plugs in so as to not inadvertently turn the engine. You may also want to replace the tensioner springs as well. Read the thread by Wingadmin regarding this and not more I can add.

An OEM tensioner is also expensive here north of the border, approximately $100.00 each plus taxes. I too had read on these forums of the tensioner rebuild option using the Gates 42105 bearing that is used on a number of cars. It is an almost perfect match for the existing tensioner bearing. I decided to rebuild the tensioners on my bike and spent $80.00 for two rebuilt timing belt tensioners instead of $200.00. Labour was about 1/2 hour per tensioner. Do not know what other bikes these are used on, but I would expect supply to dwindle. Rebuilding is not for everyone, but I have been very satisfied with mine.

Here is a picture of the finished product that is on my bike:

Here is a parts list for the rebuild for future reference using basic tools:

hacksaw
Punch/chisel - to remove old stud after hacksaw used to remove old idler
17 mm socket
6 mm hex drive
10 mm by 25 mm flat countersunk bolt
nylock nut with flat washer
Gates 42105 idler

Is there any anyting to know regarding the tensioner replacement operation? Just unbolt and rebolt the new? Anything to know regarding the springs? Just want to make sure ahead of time.

Nothing difficult about them!
Just get the tension set properly and that's basically all there is to it. I think you're reading too much into it! ;)

OK I changed the belts and tensioners today, All OK so far. I have to find a scale next to set the tension before putting it back together.

Sure as hell would have never attempted this without the forum how to articles! Thanks Again.
