timing belts

Postby grains » Tue Apr 10, 2012 11:14 pm



So, according to my last post,Mooseman says that the timing belt(s) could be loose and hitting the cover.
According to the bills I recieved from the PO, the belts were changed in 04 at 113710 KM's. I am now at 114850 KM'S so only 1150 KM'S since they have been changed, BUT 8 years ago. So time for change???????
I also looked at Rockauto and compared belts as to length, width and # of teeth as well as warranty.
The Dayco 95070 is 33"L x 3/4" W and 88 teeth with a 1Yr-1200Mi warranty. $5.32 plus shipping
Gates T070 33"L x 3/4" W and 88 teeth (no warranty info) 7.13 plus shipping
Goodyear 40272 is 33 3/8" L x 1"W and 89 teeth 12 month warranty 9.87 plus shipping
Now my question is. The Goodyear appeals to me because it is 1" wide but has 89 teeth verses the other two that is 3/8" shorter,1/4" narrower and 1 tooth less at 88.
Anybody have any thoughts????

It's not so much as to how many miles are on your belts, it because they deteriorate with age; change them .

Part numbers for timing belts:

GL1200: Gates T070, NAPA 250070

Here is what I have in my notes.

Timing Belts (2 each)
NAPA – 250070
Gates – 5043 or T070 (avaiable thru most NAPA & Carquest stores)
Goodyear – 40070

I myself have been using the gates. The extra tooth on the Goodyear bothers me.... :?:
Enjoy the ride. They are all good, just some better than others.

The extra tooth only indicates length which the idler should take up once adjusted. Since timing is made possible by alignment of the shaft pulleys and not the belt, you should have no problems.

I have tried to read up and even watched a video on youtube on how to change these belts but I still have 1 question. Do the adjusters put the proper tension on these belts or is there some amount of tension to put on them. Thanks for the info and help

The adjusters (the springs on the tension wheels) theoretically put the correct tension on the belts when the bike came from the factory. I wouldn't trust them now.

The tired old adjusters on my 1100 put nowhere near enough tension on my belts. On the other hand, the adjusters on my 2000 GL1500 put precisely the correct amount (4.2 lbs).

On the GL1200, you should get 3-5mm deflection with 4.4 lb of tension applied to the belt opposite the tensioner. For more details on this, have a look at the GL1500 version, starting at step 101: How to remove and replace your timing belts
