Pictorial: Replacing the gearbox input-shaft bearing

The Issue:

Bearing noise from the left side of the Car.

When:
1. While stationary after starting and in Neutral
2. While in movement, in all gears. More predominant at gears 1, 2,3. Though the noise is there at gears 4, 5 the speed of the car and wind noise makes it difficult to notice.
3. Goes away when clutch is fully pressed

How to identify:
After starting, in neutral listen to the bearing noise in a silent zone with your car. Press the clutch completely in, the bearing noise stops, since we disengage the gears. Release the clutch slowly back, the bearing noise comes back.

If you get a noise while pressing the clutch in, it is a noise from your release bearing.

Diagnosis:
INPUT SHAFT BEARING NOISE

How does it sound? How can I recognize?
Here's an audio of the issue


I had this issue on my Civic, you can read about that here (Pictorial: Replacing the gearbox input-shaft bearing on my Honda Civic)

What Should I do if I get this issue?
You need to change the Input Shaft Bearing. The OEM bearing is from SKF. It is a Deep Groove Bearing. While you do that, its a good thing to replace the Oil Seal as well.

OEM Part Number
1. 24155 M 68K40 - INPUT SHAFT BEARING, Costs Rs170
2. 24151 M 68K00 - OIL SEAL, Costs Rs 20

Input Shaft Bearing

Oil Seal
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_135445edit.jpg

It would be advisable to do this at a good garage, since the whole Gearbox have to be downed and you need the genuine components, trained mechanics, access to good quality tools and a lift. You would definitely be looking at a full day of down time for your car.

If you can source this components, since these are not moving items, you can work with your trusted FNG. Key here is the component, and it's quality. Since this is a labor intensive job with huge downtime, its better to do it with original components. Well, we don't want to keep opening Gearboxes all the time, do we?

What did I do? What was wrong with my Swift?
I wanted to clearly understand the issue, so I asked my trusted and Skilled Mechanics at my favorite FNG to down the gearbox and show me the Input Shaft Bearing.

Here it is as expected: See the broken bearing!
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_125323edit.jpg

The parts were not available locally. Since by now with the previous experience in Civvy, I was quite sure about this and had sourced the parts from Boodmo before the exercise.

The broken and the new bearing for comparison
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_125450edit.jpg

It took almost a day to down the Gearbox, to remove the bearing and assemble back, and to put the gear box back in place. Labour intensive work, indeed.

More about the work and pictures in subsequent posts.

Disassembled the whole gearbox for cleaning up and removal of any metal pieces that might be there from the broken bearing

The gears and the shifting rods

A look into the components inside the gearbox

1 - is the input shaft
2 - is the oil seal
3 - is the input shaft bearing


The input shaft bearing (1)

This is the input shaft bearing LH, 14 in the picture, part number is 24165M68K20. Looks good, so not changing this guy.
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_130340edit.jpg

After thorough cleaning we started to assemble it all back.

The differential assembled, the hole to the left is where input shaft fits.
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_133648_01edit.jpg

You can see the old oil seal still in place. It was good.
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_133738edit.jpg

But as a good practice we changed it with new

Gear shifting assembly done
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_141322edit.jpg

Now that we have downed the gearbox and did so much, I thought to have a look at the crankshaft where the flywheel is attached. It also has a bearing, and that is also called Input shaft bearing.

Crankshaft diagram
Pictorial: Replacing the gearbox input-shaft bearing-crankshaft-diagram.jpg
17 - is the flywheel
19 - is the input shaft bearing

We removed the flywheel and got the bearing. The bearing also had some noise, so we decided to change it.

After removing the flywheel, and the bearing

re: Pictorial: Replacing the gearbox input-shaft bearing

Flywheel Details
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_151735_01edit.jpg

New flywheel
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152316edit.jpg

Comparison with the old flywheel
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152327edit.jpg

Now that all this happened, thought of checking the clutch and replacing it if life is less proactively

Clutch details
Pictorial: Replacing the gearbox input-shaft bearing-clutch-diagram.jpg
1 - is the pressure plate
3 - is the friction plate
4 - is the clutch Release bearing

The old clutch friction plate
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_122840edit.jpg

Its almost done
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_122850edit.jpg

So we decided to change it too

Friction plate details
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_151725edit.jpg

The new friction plate
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152341edit.jpg

Comparison with the old worn out one
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152359edit.jpg

Pressure plate details
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_151656edit.jpg

The new pressure plate

Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152524edit.jpg

So now only release bearing was left in the transmission part, so we change it too

Release bearing details
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_151708edit.jpg

Clutch Release bearing
Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152702edit.jpg

Pictorial: Replacing the gearbox input-shaft bearing-img_20171023_152709edit.jpg

Well that makes it all new and good to go. So we assemble the gear box back to my Swift. A small bearing change gave me a good time to change all the needed part and its good to go a long way now.

re: Pictorial: Replacing the gearbox input-shaft bearing

Some relatively different jobs were also done on the swift. Since it was on the lift, I kept checking out the suspension components too. To my shock the front struts were leaking. That was too bad!

Both left and right struts are leaking crazy, needs immediate replacement

All these activities were done in October 2017. Swift has done 25K Kms after that, and is doing quite well. This January Swifty became a teenager at thirteen and 87K Kms on Odo

re: Pictorial: Replacing the gearbox input-shaft bearing

Sorry if off topic but why was there difference in the price of LH and RH Struts?
RH Strut cost approx. Rs. 300/- more than LH Strut.

May be something to do with taxation or manufacturing dates or different batches. They look the same

Re: Pictorial: Replacing the gearbox input-shaft bearing

First of all thanks for compiling such an informative thread along with photos & part numbers. Will be very helpful for Swift 1.3 P owners like me (I too have a 06 Swift Zxi). In my car thankfully there is no sound from the gearbox yet, though I will a keep an eye on it.

I did however get the whole suspension overhauled, including rear shock absorbers. Now the car rides better & suspension works more silently as well. The clutch on my car is still very light, though there is a prominent judder while starting off in 1st gear. Maybe, I would get that replaced as well going forward. Did you find any difference in acceleration after changing the clutch?

This got me thinking, so I checked the part numbers of the Struts that I had bought. Same story here as well, around Rs. 300 difference between them. The part numbers also matched. I guess the difference is most likely due to different vendors.

Here is the part numbers of the Struts:

The clutch had judders, and after the change it went off. But by the look of the clutch friction plate it was almost on its end and explains the judder. But it did not slip at that stage. After change it became light and was good to drive. Acceleration wise did not notice much difference though.

The labor intensive part was the removal of the gearbox from the vehicle and opening it up. Once opened, removing the input shaft bearing and replacing with new bearing and the new oil seal was fairly very easy and quick.
