Engine mount replacement

[ribbert]

Guys the next time we do this we will have a look at the rear mounts they are a little more difficult to do may only be able to do 1 or 2 bikes also if we do this in the right place may do the nipples in the front and rear just to make it easier to maintain!!

Baldy, I have just had my rear suspension to bits this week and was about to fit grease nipples as some of them had dried up and started to rust. What stopped me was the front bearing on the relay arm is a single full length bearing as opposed to the others with one at each end. That would mean having to remove that bearing to drill the hole.  My previous experience suggests there is high risk of stuffing it up trying to remove it and I could not get a replacement in the time frame I had. Those needle rollers have a very thin outer race.  So, I just cleaned them to get rid of ALL the old grease in a kero parts wash, greased them and put it back together. I think there is an excellent case for doing this but you would want to have a new bearing on standby. .  It's a lot more work getting to those than the engine mounts, there is more of them, they cost more and they cop a lot more water.

Hello ! I just finished up rebuilding my 1990 FJ  relay arm. I just wanted to mention that the small bearings in the relay arm that bolts up to the bike. The ones that seem to get rusty an disintegrate... I also thought about a nipple but the design didn't lend it's self to doing that. But I did discover that you can purchase from a bearing supply company this bearing  Koyo bearing HK 1816,  fits perfectly and is a little longer, cost  5.77 each 2 for 11.54 here in the U.S. ... Less money, more bearing surface. (interesting note, Koyo "Made In Germany"). Its just a longer bearing. And I packed the crap out of it with marine grade grease.
Oh and I found out that the larger bearing that are located where the dog bones hook to are unfortunately Yamaha only bearings

Shows the size difference. The stock bearing is also a Koyo... Quality appears to be the same.

Thanks yes I know its a tough job wouldn't contemplate this with out having a few replacements but just cleaning them up and regreasing them is a good idea, also I must get some photos of my US bike as the PO had installed nipples all over the suspension arms.

Yes Mr Yamaha is very good about doing that and not being able to get them anywhere else but Yamaha!!!

Can anyone read this ?  I think they are saying there is an interchange on a part number between Yamaha and Suzuki . The bearing looks like the ones in the dogbone end of the relay link (the one only available from Yamaha). ??  http://www.carookee.de/forum/Yamaha-FJ/26/Info_Lager_Umlenkung.26218791-0-01105
