Timing belts and or tensioners

Postby BOSNBOB » Sun Feb 14, 2016 2:10 pm



Hey all have a technical question. I have a 1993 1500 aspencade and I believe the timing belts or tensioners are bad . I have changed them on a 1200 before but I have a 1500 now. Do I need to pull the engine or not and how how long to complete this task. I am going to Daytona in early March and I want to get it done or I don't go.

No need to pull the engine on a 1500 for this. You do need to remove a lot of plastic, but it's not that bad. Count on several hours, mostly for removing & refitting the plastic parts.

There's a VERY well put-together step-by-step DIY photo essay here: viewtopic.php?f=14&t=9774 (done by our resident guru WingAdmin!), on the GL1500 DIY listings. Take a laptop or tablet out to the garage, fire up the essay, and have at it. Follow the instructions, IN ORDER, don't miss a single one, and you're golden.

The Gates (or alternate) belts are widely available. I didn't need to replace my tensioners, but I believe they're widely available as well.

I just did mine a couple of moths ago, with the Gates belts from Amazon, as none were available locally. They were Gates T275, as I recall. Did it with assistance from my son-in-law, which isn't necessary, but very helpful. I did it with the help of the How-To that was mentioned above. Had no real issues. Just followed the How-To, EXACTLY as described. Probably took 2-3 hours with some goofing off, in between. All that comes off is the lower plastics in the front. Not a big deal. I did NOT drain the coolant, as I had recently changed it, and didn't want the hassle. It's more difficult with the hoses still in place, but easily do-able.

You say, "I have a 1993 1500 aspencade and I believe the timing belts or tensioners are bad". What are you hearing or experiencing that leads you to that conclusion. My understanding is that bad belts will exhibit no symptoms before they break, and that is the real problem. They are generally replaced as a preventative measure, based on age or miles. 5-6 years, or 100K miles, I have read. I changed mine on a '97, with 54K miles, and I'm pretty sure they were original. WAY past recommendations. I guess I was lucky. My tensioners made no noise, before or after the change, and inspected as good while I was changing the belts. So, other than it's a really good idea to stay on top of those belts (as your engines life depends on them), why are you concerned about them ?

take comfort in knowing it is a lot easier to do the belts on the 1500 than the 1200
at least I thought it was a lot easier. if you have done a 1200 this will be a breeze for you
follow the tips and or tutorials you can have it done in about 2.5 to 3 hours

I am hearing a whinning noise like something vibrating or something of this nature and it is coming from that area. Any ideas, I have 33,000 miles and its a 1993. Aspencade-A.

Well, it sounds like it could be the tensioners (a video with the camera near the timing belt cover would help us, here). You won't know for sure until you get in there, but you will be taking them out anyway. If they spin free without any resistance at all, the internal lubricant is probably gone. If this is the case, you'll hear a hiss when spinning them by hand, which would confirm they're dry & soon to fail.

As they're nowhere near "free to a good home" (around $150/pair at RonAyers.com, for example - both tensioners have the same part number), my best advice would be to post a video, with sound, as I mentioned. Try to face it from behind the front wheel toward the timing belt cover, and have someone rev the engine just a little (so we can hear changes in the sound with RPM changes). From that, the pros can give you their opinions & help you decide if you need to purchase tensioners before digging in to the project.

Of course, you might be able to find a pair of low-mileage used (known good) ones to have on hand. That might be preferable (and a bunch cheaper) than ordering a new set. I see the odd set on Ebay for around $40, but their condition is, well, who knows?

Hope this helps.

I would think it wise to determine the exact source of the noise before ordering parts. You can follow the tutorial up to the point where the timing belt covers are removed, without draining the radiators. At that point, you can run the engine, and using a mechanics stethoscope, you should be able to easily determine if the tensioners are the source of the noise. I believe the coolant pump is in that same general area, and is a possible source of the whine you are hearing. Again the stethoscope will assist in narrowing down the exact source. 33K miles sounds a bit low to be having problems such as this. You could also visually inspect the belts, specifically the teeth, and their static & running tensions, in case the belts were replaced and misadjusted too loose, causing premature belt wear or rubbing on the case.

Timing belt tensioner(s) are still available for the 1200 and 1500, and are the same P/N 14510-MG9-008. I chose to use the tutorial for rebuilding the tensioner. It worked well and cost me $80.00 CDN for two instead of $200.00 CDN from Honda. Once you have the parts, you can rebuild the tensioner(s) in about an hour. You can find this information by doing a search on this site, or the Steve Saunders site. I did mine because I expected them to be original. If you do the tensioner(s), you might want to change the tensioner spring to ensure the proper tension. Cheers

I keep seeing this mentioned, I have done belts on 2 different 1500's and did not find that I had to drain the radiators
I found it fairly easy to work around them and the coolant hoses

I didn't have to drain my radiators when I did my belts, either...awkward, but doable.

As they said. PLUS make sure you have all the tools you need including a Torque Wrench (mine had been "borrowed") and a gauge to check the belt tension (WA has a good example in the tutorial).

My biggest problem was reinstalling the plastic (first timer) after completing the work. I thought I knew how it went but had to go all the way back and follow the tutorial to get it right.

Replaced the tensioners when I replaced the belts a couple years ago. Only 28k on them but didn't mind replacing them. Belts looked fine but felt a little stiff. Tensioners seemed fine. Was worth the peace of mind to do it all at once. Very expensive those tensioners. Honda must have given those extra blessings before the boat trip to the states :lol: :lol:
