I replaced the timing belt, but boy is it tight. I put in a Dayco 95171k1 timing belt. It fits, but the tensioner is literally maxed when in place. Meaning the stud is a the bottom of tensioner arm arc slot. Is this normal or did Rockauto send me the wrong belt? I doubled checked there numbers with the box and that is the one for the 92 GT. I will double check the belt tomorrow and make sure the numbers match.

Yes, a new tensioner came with the belt. It matches the old tensioner, but it is possible they are both the wrong part. Yes, I am positive it is on the tit.

I checked at two different autopart stores and neither has a listing for a different belt or tensioner from 89 to 94 for the dohc 1.3. I'm off to take another look at the different images online, they appear to be the same way. If anyone can think of something else let me know. I will post an image later.

Some parts websites claim the Dayco kit you used fits only 89 to 90 GTi and state:
Quote:
This part is not compatible with 1992 Suzuki Swift GT Hatchback 3-Door 1.3L 1298CC 79Cu. In. l4 GAS DOHC Naturally Aspirated


However, I think JV&S is correct about the possibility that you received the wrong tensioner (n the right box). Can you compare your old one to the new one?

OEM part numbers:
1989-1994 Swift SOHC 1.3 8V
Part Number: 1281082003

1989-1994 Swift DOHC 1.3 16V
Part Number: 1281053B01

1995-97 Swift 1.3 SOHC 8V
Part Number: 1281071C02

1998-2001 Swift 1.3 SOHC 16V
Part Number: 1281071C02

You have the wrong belt.

I have NEVER seen a different tensioner on the GT's. They are all the same.

Take the belt back off and lay it on top of the old one and stretch them with your fingers to compare lengths.. It should give you a rough idea of the lengths.

A belt thats too tight will risk breaking the exhaust cam between cyl 1&2 if you have hollow cams. I don't see how it can affect the seals.

And a timing belt should never stretch.. Ever.. It would defeat it's entire purpose of keeping the cams and crank in sync.

It is the exact same as the one I pulled off. I put the old one back on and it does the same thing. There is no different tensioner, and it is the same as well. I will post the picture I took. Everything rotates fine and is smooth. Maybe I just have it backwards in my head. I can't find an image of the tensioner and stud in a different position. All the images I have seen show it in the position that mine is at.

You might even be able to see on the tensioner bracket where it was tightend down before.. The might be marks on it from the washer to give you a good idea.

The image below was posted by JV & S in a reply to another member's timing belt posting. The picture shows the bolt in a similar position to your photo.

By clocked, do you mean rotated clockwise by hand to pick up what the directions say slack in the belt?

Just so you know, there are 3 different timing belt tensioner diameters that are available.
For the guys that didn't shave heads or blocks you need the small one on the right which is for DOHC engines.
For all the other SOHC engines the middle one seems to do the best.
The large one to the left is for those engines with shaved heads and blocks, where it looks like you won't have
enough movement on the tensioner to get the tension right.
The tensioner arms shown, left is for the DOHC and most of the other engines, the right one is for the SOHC 1.3L
16 valve engine using the middle tensioner.

The better question would be what are the diameters for the different part numbers that suzukitom listed?

Rockauto had the diameter of the Gates GT tensioner pulley width at 28 mm and the outside diameter as 51 mm. The individual package for the tensioner with the Dayco kit was 430-8940 (Sku #) and a part number 85221UB. This matches what Rockauto has for their image part numbers for the GT. It also matches with several other online vendors with DOHC OEM part # 1281053B01. However, several sites have the B as an 8. I am still not comfortable with the timing belt fit. I will double check everything when I put back on the lower timing belt cover. I am also waiting to receive my 91 1.3 FSM to see which position the spring should go to.

I would appreciate if you could get the diameter off the smallest pulley.

The diameters are
Small 42 mm x 25 mm wide
medium 46 mm x 28 mm wide
Large 58 mm x 30 mm wide

The small and the medium came off of core engines that I have
here at the shop. The large came with a timing belt kit I ordered
from Rock auto.
Looking on Ebay this morning they list other diameters.
The Gates T41009 looks to be the smallest diameter.

Both the one I pulled off and the new one are 42 mm diameters. There is a difference in the width between new and old 28 mm and 25 or 26 mm for new (didn't get the best measurement on it), outside width. The new still has the same internal width (a way to save on metal). Anyways, it is the smallest tensioner, and the marks are dead on and everything sounds right.
