Gl 1100 timing belt questions

Postby new82 » Mon Oct 24, 2011 6:42 pm



Ok - I pulled the radiator, timing covers & belts. The belts look like new - no cracking, fraying or signs of wear. the tensioners seem fine too. I don't know how many miles or years are on the belts - they are honda OEM belts. The bike has about 60k on it but I'm pretty sure it's been opened at least once before. I have new gates belts to put on, But I'm tempted to go back with the honda belts.

Is there anything specific I should look for in deciding to go with old belts or just replacing them. Regardless, I'll have new coolant, radiator hoses, oil & filter when I go back together with it tomorrow.

BTW Wing, I waited until I had the radiator loos & swung out to disconnect fan plug. A lot easier for my fat hands. Also, I'm glad my fake tank doesn't have all those air compressor connections to deal with. Also my water pump feels solid, so I shouldn't have to open up that can of worms any time soon.

Jim If you do not know when the belts were changed then they need to be changed. Old belts may look brand new but if they are old they could break at any time. If you replace them now it will give you peace of mind the cost of replacing your engine verses 30.00 belts no brainier . Good Luck Hal

I "inspected" the belts on my 76 and they looked like new. 1000 miles later I was rebuilding the left head. The belts never show signs of wear. The cords inside are what give up and break. I advise replacing them as the Gates belts are excellent quality.

Well obviously you WILL be putting on the new belts.
Check the idlers,get the tension right,and HAND turn over the engine first.Re-check the timing marks and the tension one more time before you button it up.

Thanks everyone.
I did go ahead and replace the belts. I'd pretty much decided to after I made the post, but your opinions helped. It went smoothly - I have a tip for anyone planning to change belts in the future. After changing Left belt & adjusting tensioner, instead of fighting springs on on right side, install belt on tooth off & bolt up tensioner. then rotate 360 degrees so that camshafts face in. Pull tensioner and adjust belt, then re-install tensioner. You actually have to have it here to set the tensioner correctly anyway. Then rotate 360 again to check.

The only other issue I had was a slight coolant leak at the lower hose flange. there as some kind of white sealant on it before in addition to the 'o' ring. I put permtex on it but didn't allow it to cure before filling & testing. So.. I had to drain coolant & redid
the connection with the silicon sealant that I I used for the timing cover on my nissan Pickup. It needs 24 hours to cure, so I'll refill & test tomorrow. should be fine.

A quick story about SILICONE.Not related to what you did.

Many years back,my brother(certified Honda mechanic)was assigned to repair leaking valve cover gasket on a NEW Goldwing. The owner was on his maiden voyage,1000 miles from home.
My brother "FIXED" the leaking gasket with RTV Silicone and sent him off.

Well 3 hours later,the new bike arrived back at the shop with a seized engine.

The dealer had to give the man a new bike.

It seems that the Silicone bead that was on the gasket came off and plugged the oil channels,and screen.Effectively running the bike with no oil.

The last I heard,the dealer only allows him to assemble bicycles and clean toilets.

I'll add my question: after replacing the belts, when you turn it over by hand are you checking for things to clear by feel or what? Noise? I'm probably going to have to check my timing this winter and I'd like to not jam things up.

You're checking to make sure the valves aren't hitting the pistons. Because you should have the plugs out to make the engine easy to turn over, there should be very little resistance - if you feel any sudden resistance, it's a piston hitting a valve, so STOP and back it off, then figure out what you've done wrong.

It's very important that the belts are not too tight or too loose at any point of your 360 degree rotation, yes, feel the belts as you rotate it especially at 180 degree's or half way of that rotation....
