Tr1 83mod starter issues
29.07.16 at 21:06:26
 
Hi,
My first post in the forum.

I recently bought a TR1 83 model. It has been slightly modified towards a cafe racer, and I hope to make it shine a little bit more in the future. I will add some pics when I have it runnng again.

I have some issues with the starter, but I do not know what. I suspect it could be the starter clutch, but I lack knowledge, so I was hoping someone could watch the video below and listen if they think the clutch is the problem? The starter spins but nothing seems to "catch"..? Any input appreciated.
I have used the starter a lot lately, as I have struggled with the fuel crane, and it has gone from okay, to worse to now like in the video.

Mabye it is the clutch causing the problem, but if the lever is not pulling correctly, see here-  https://www.tr1.de/pages/technics_manual.php?iQuery=key=xv1000&lng=eng&flg=0&pge=0008   - you will have a similar issue. Remove the small lever-cover, push the lever manually as far as it is possible , using a screw-driver or a bolt.  If there is no success, remove  the left engine-cover and look for wear to the clutch and the gears,
regards Ali

Thanks, Ali! I'll look at this tomorrow.

Hello

Check what Ali said first.

It sounds as if the clutch is engaging and the starter is spinning. Have you had the side cover off yet. I came across an incident recently with a TR1 with no intermediate gears fitted, So remove the side cover and check if the gears are there!!

The planetary gear can also spin within the starter motor itself. It normally allows a little engagement of the starter mech so it sounds like you would have extreme wear to allow that.

I would you remove the nearside covers and check all the mech is there and functioning.

Are you based in the UK? if so where?

Best of luck.

Hello again.

Whoops....  I should have read your post more carefully. My apologies.

If it is getting worse you must have the intermediate gears in place. It could be the planetary gear in the starter motor slipping. The planetary gear is pressed into place and should be fixed within the starter motor case. If it rotates within the case there is no drive to the starter motor clutch and no drive to the starter mech.

Best of luck
Kevin

First: Ali, I tried to push the lever all the way in. Ignition was off, and the starter was spinning for a second one time. I also tried to start it while the lever was pushed all the way in, but no difference.

Kevin: I am in Norway.. Smiley It has gone from working just fine to doing as in the video in a few days with (stupid me..) a lot of work for the starter, trying to start with the gas crane in On-position, when it should have been on Res...
I have removed the engine oil, and will check behind the engine cover tomorrow if I can find the time.

Earlier I did remove the starter, and looked at what I believe must be what you are referring to as planetary gear, after googling it..Smiley Now I only remember that I pulled out the gears and looked at them, they looked okay, and I inserted them back in. I believe it was possible to rotate them manually, but I am not sure.

I will anyway try to look for wear on the clutch, and see if I can get closer to a solution. Will update when done.

Thanks to you both. Smiley I havent done any mechanics for 25+ years, and then it was only on my Yamaha DT50, inserting a big(ger..) bore kit, going from 2.5 hp to 7.5 hp, which was fun enough, and some other minor stuff, so my knowledge and skills are on a very low level, and I am grateful for your patience.

Hello

As you have used English to describe your problem I thought you may have been in the UK and I could have possibly met up with you to help fix the problem. Norway is just a little to far.   Smiley

The starter motor effectively has a small gearbox on the end of it. That is the planetary gears. If you pull the starter motor apart you will see there is a toothed gear on the end of the motor shaft. Around that you should have two small gears which are free to rotate. The two small gears fit inside a larger circular ring. That circular ring has gear teeth on the inside of it. The circular ring fits inside the end of the starter motor housing. It is a push fit and should not move. If you can move the circular ring within the housing or can pull it out that is your problem. It should be fixed and not rotate. I hope that all makes sense?

If you do have that problem you can either get the circular ring tack welded into the starter motor housing. Or, you can do what  I did and drill and tap a hole through the starter motor body and into the circular ring then insert a screw to hold it.

Best of luck with your diagnosis.

Kevin

I'll buy the plane tickets for Norway, and pick you up in the airport! Smiley

Better see if I can fix it myself first.. Smiley I removed the starter again, and as you can see in the new video, the outer weel does spin around, and it is also possible to pull out and remove.. I'll try to fix it so it doesnt rotate.

Thanks again, Kevin!

First time I removed the starter, one of these small splinters fell out. There are space for 4 of these around the outer ring with gears inside, but no others are present.

Hello Roger

I can see the problem in the video. You zoomed in on the outer ring and the planetary gears. You then placed your finger on the outer ring and rotated it. That is your problem. The outer ring should not rotate. It is a press fit and should be tight.

You can either remove the assembly and replace it. Or you can remove it and spot weld the outer ring into the starter casing. Or, without removing it you can drill a hole through the side of the casing and into the outer ring. Then tap it and fit a screw.

Best of luck.

Kevin
