((Up date))Timeing belt (1 or 2 belts?)

[macdoesit]

My I/S has 36,000 miles is it time to replace  timeing belt, if so is there anything else I should replace while the cover is off? Correct me if wrong but if belt breaks that will cause a lot of damage.
 As always  thank you for your time and info.

Up date--1 or 2 belts? don't want to take cover off till i know as much as I can.
2 conflicting diagrams.

[Bone]

The Honda Manual says to inspect the belts at 100K.

OK, thanx, I don't have manual

Why is it time to change them, having problems?  

Just in case you unaware, there are cheaper alternative sources so read the tech notes...here's a clip ?....  GL1500 Timing Belts. Goodyear 40275 timing belts are available for the GL1500. Gates have been supplying the T275 timing belt for the GL1500. Also available is the Napa 250275. Note that the same timing belts fit all GL1500 models from 1988-2000.

Have you done the trigger wheel change?

I believe the manual is available online...as a d/l in PDF.  http://www.valkyrienorway.com/download.html

The reason for asking  my Brother has Mitsubishi Stealth his timeing belt broke while on the highway bent push rods etc. Also I don't know if there is an age limit on the belt, after 13 years does it start cracking from age? I don't know what the trigger wheel is. I'm not to savy on the motor parts.
36,000 on bike

  thank you.

pop off the front cover and take a look, the bike is new to you so it can't hurt to satisfy your mind. while you in there you will see a pair of electronic pickups that sense the position of the engine via the trigger wheel (round disk with small tabs sticking off it) the tabs pass through the pickups thereby triggering the computer to fire the coils. you can replace this trigger wheel with ones that have the tabs in different locations to provide either a 4 degree or 6 degree advance over stock timing.

Which would you sugest 4 or 6 degrees and why? What is the degree of stock timeing?
Thank you.

i went with the ect mod as it is variable and can be turned off as well at being automatically shut off above 3000 rpm. i have seen an increase in the butt dyno power as well as a 3-4 mpg increase depending on how hard i drive the bike. all for less than $10.00 !

I think this is above my paygrade, I'm lost.

pretty simple to do. basicly you pull rt neck cover cut one wire put in resistor or pot and strip othe wire to connect the diode. it tricks the temp sensor into thinking it's much colder, thereby, advancing the timing. the advance is kicked out at 3000 rpms by the computer.
does something similar to the timing wheel but can be shut off rather than having it on all the time

I would have to have a diagram, I don't know what you mean by right neck cover and cut one wire, or( pot ) and strip other wire.

[john]

the belts will look like new when you remove the cover ....             
don't bother ... ride  .... enjoy ....  don't work on it                       

[R J]

Rule of thumb.

You want problems?

If so, start mucking with it.

If no problem, just get on it and ride like ya stole it.

[PhredValk]

WW, all of the above modifications, as well as many others can be found on the Shoptalk page, listed in the links at the top of this page, or on the Home page. Spend a few hours in Shoptalk, you will learn a great deal about your bike.

Woodwizard.  It cant hurt or cause problems.......taking the timing cover off is not (mucking with it) You have a legitimate concern and I would want a look at them belts too.  Take the cover off while the engine is warm, that way the one bolt that has sealant on it will come out easier.

Once the cover is off look real close at both belts grab a hold on the longest (loosest) run and give it a slight twist and look where the rubber nubs are joined to the belt.  You are looking for dry rot or any cracking.  If the belts both look good and feel good and you cant find any rot or cracks then dont do anything just put that cover back on

[F6BANGER]

WW, make sure you keep the bolts in order. There are 3 different length bolts as per fiche. #18,#20,#22.

Just replaced mine at 44,000, and they looked like they would have made it to 100K, but I just felt better replacing them because of their age (15 years).

That makes sense to me. 15 yrs. is a long time.
Although I've never heard of a Valk timing belt breaking, it is cheap insurance to change them.

Ditto - most of our bikes are teenagers now.
2 belts and a little time MUCH CHEAPER than an engine. 

[bobm]

finished changing my belts about 30 minutes ago .... old belts looked fine but 15 year old bike and no history of maintenance .... feel happier now

btw no real problems job was straightforward and suprisingly engine started after

I agree. No one can say if you should or should not look at or even change your belts. Like stated, the manual says only to inspect at 100K miles, and you are far from that. If this was a car, I would forget it, but being a bike, I would consider it, but like Chris mentioned, look them over, you could always leave them for a few more years.



Someone will correct me if I'm wrong, but I thought with regards to the ECM mod, you don't need it, or it wont work on the IS model, it is already built into the ECM?

Also the trigger wheel, doesn't the IS model also already have a degree built into it, and the trigger wheel might be a waist? I have someone local to me who says he has the 6' one in hs IS, and can now get the front wheel off the gound.

Timing Belts
Gates timing belts are OE-equivalent or better in service life and performance.
• Aramid reinforced nylon jackets and back side jackets for longer wear.
• High grade HNBR rubber for superior heat and contamination resistance.
• Premium high strength tensile members.
• Unlike some competitors, Gates does not substitute inferior belt constructions for premium
constructions specified by the OEM on any application.
• Most extensive coverage in the industry. Import or Domestic.


this is for higher underhood temps with no airflow on the belt area, which our engines are not.

EPA law requires anything on an engine to do with emissions, timing belts are one item to be warrantee for 105k miles. So by law the belts were designed to last that long. Part age is not part of the law only mileage.

[CASABROKER]

I changed mine because of age 14 yrs. not miles.  Probably didn't need it belt looked brand new.  Got the gates on amazon for 38 bucks to the door.  Changing it just gave me something to do, it was easy.

all use the same OEM TW.
I/S ICM has a faster steeper advance curve to 3k than non I/S after that the curves are the same.

see curves here, which also shows area that the ECM mod affects

[Hoser]

I think is more likely that a screw up in installation is more likely to cause damage than a bike with that mileage breaking a belt. And don't trust a dealer to have a mechanic with a whole lot of experience in the procedure, it just doesn't need done often. JMHO Hoser 

[SANDMAN5]

I replaced mine at 60,000 miles. They looked great.
Could have easily went another 60,000, IMHO.

[Old Geezer Richard]

 Hey WoodWizard , just remember that these timing belts don't stretch like the belts on your car , OK ... just they said look for dry rot or cracking and if look ok then put the cover back on and ENJOY  I myself changed out the belts at 51,000 miles when I just my bike ... reason being , I had an Old 1980 Goldwing 1100 and the timing belt broke on me , it felt like I just ran out of gas ... so the more I kept cranking the engine I bent the hell out of everything ... lesson learned , but the new belts from gates are dynamite as far as long lasting ... take a look and sleep better tonight ... Thanks the Geezer

[Hard Luck Rodeo]

Mine has 75,000 miles on it.  I hope to get another 25,000 out of it.

[SPOFF]

The OEM belts on my Dad's 1976 Gold Wing went 27 years without fuss. Probably are still going... lost track of the bike after my brother sold it.

[sugerbear]

but, please, buy or download a manual. read it.
preferably while sitting by the bike so you can see the part their talking about.
lots of great knowledge here. tips and tricks learned over the years
also go to shoptalk and read everything you can find.
if you don't understand something ask BEFORE putting a wrench to it.
just like the belts, you did good. keep it up.

[RonW]

sugarbear, sound advice. If you misalign the marks you'd only self-inflict as much damage as a bad belt would. I suspect the veterans are making it sound too simple. At least, they never bother to mention the possible mishaps. Haven't done it myself yet, but I plan to read up on it for a while before jumping in. Perhaps just end up blowing out belt dust. If I had done it earlier, I probably would have neglected to dab on sealant to that bolt (second pic below) or counter to what Chrisj noted taken the bolt off while the engine was cold. The relevant articles in Shoptalk are for swapping out trigger wheels but they're also an invaluable guide for aligning the parts properly. Nobody wants to make a video so far I guess.

[macdoesit]

I have not taken cover off yet. I'm getting conflicting diagrams, one shows 2 belts, another shows 1 long belt.

[Valker]

All have two belts only.

[macdoesit]

The reason I ask Ronw 3 replies up looks like 1 belt.

The belt on the right side (looking at the picture) is actually behind the one closer to the camera. There are two toothed sprockets in the middle, but you are right about it looking like one belt!

[RonW]

The right and left belts are offset from each other including the tensioners something like the graphic below. The only reason I wanted to pull the cover was to spray the backside of the cover with a sound deadening compound but then there was potential issues with the compound flaking off and screwing up the operation.

i went with the ect mod as it is variable and can be turned off as well at being automatically shut off above 3000 rpm. i have seen an increase in the butt dyno power as well as a 3-4 mpg increase depending on how hard i drive the bike. all for less than $10.00 !

At 36K miles, why don't you leave it alone and ride it.

[Patrick]

These engines all have 2 belts.. As mentioned, if they are installed improperly then quite a bit of damage can occur.. If installed 1 tooth off the valves will end up having a serious argument with the pistons.. The pistons always win.. Engines don't run well with even one bent valve..
