Timing Belt Install Problem

Post by petecracknell »



I have changed the belts previously on my 97 SE using Gates T275 with no problems. I am now changing the belts on my 93SE using Honda belts. The left belt went on well. I cannot get he right belt to slide over the tensioner. The belt is taut across the bottom, teeth are engaged on crank and cam pulleys, the tensioner is loose and sliding on the right side bolt. Yet, I cannot get enough slack to get the belt into position.
The only difference, other than the bike itself, is the brand of belts.
Any suggestions?

I would take both belts and measure them against the old belts that you took off. Make sure that ALL of the belts are exactly the same size.

Swap the position of the belts. If the right side won't fit on the left, but the left fits on the right, there's something wrong with that belt.

Welcome to the forum.

It's sometimes a bit hard to get the tight side on correctly and be a tooth off. Also, it is sometimes easier to take the bolts out of the tensioner, get the belt on and tight on the tight side then push the tensioner into place and get its bolts started (pay attention to the wire holder as they have locating pins). Hand tighten the tensioner bolts. Check your line up marks to make sure you're not off a tooth.

Further to using the suggestions given by members;
new belts same size as old,
removing both bolts of right side tensioner allowed me to install the belt.
Have to check tension on belts. Somewhat awkward using the scale and ruler. Any tips on how to perfect the procedure?

I just replaced my belts over the weekend and didn't bother with the luggage scale and ruler. I just kind of adjusted them until they felt right, maybe half an inch of travel on the belts. Seemed to work just fine. I basically just made them feel like the old belts did in terms of tension. Completely unscientific, but it worked for me haha. The pressure from the tensioner springs seemed to be about right without adjustment, even on my 88 GLA.

Thanks for the input Kyle. I did something similar when I changed the belts on my 97. I put various marks to show where the tensioner bolts were before removing. I thought I would get fancy with the scale and ruler and failed to put the marks on the 97.

I wouldn't go by that, the replacement belt may not be exactly the same length.

I use the unscientific method, too. Simply tighten them until they "Feel Right". :mrgreen:

I tried the luggage scale and ruler. PITA. I put my belts on, set the tensioners and on the long side of the belt (opposite of the tensioner) in the middle, I turn the belt almost 90°. That is usually set right.
Years back working in an automotive shop and putting on countless timing belts, from Hyundai’s to Porsche’s, it hasn’t failed yet. One of the only engines that didn’t work on was the Mitsubishi 2.0 liter with dual overhead cams. It had to be tight before the tensioner was set. Too loose and one cam would slip and bend all the intake valves. Fixed a few of them after a shade tree mechanic replaced the belts.
