Jawa R.T , T.S. 350.caferacer Small End Loose Needle Roller bearing's Removal & Refitting Tool

[enfielddnepr]

There are caged roller sets, which are reccomended because the won't rattle around in the higer revving area(and running hot/jam) i don't know if this is a real threat, but maybe it's an easy upgrade?

[terence20001]

Hi , Yes i've used these caged small end roller's since 1985 , first in my 634 and found them good , But now and again in the 638's i've built one will fit and the other will be tight , there are oversize loose roller's that are fitted maybe due to bad tolerence's in small end bush ? not sure . So in some cases i put back what i took out in exactly the correct order , i've never had problem's with over heating small end's but you may get this problem if oil/petrol mix is wrong . Terry

[enfielddnepr]

And, don't you need to REPLACE the needles and outer bush when they are worn? you set the same ones back!

[terence20001]

@enfielddnepr Hi Yes of course :-) If they are worn on this model you can buy caged roller's , but you have to get right over size piston pins , they come as 16mm 16.25mm 16.5mm and so on till 17mm . Or fit new conrod kit's . But if these loose roller's are servicable there's no reason not to put them back . Thank's for your comment . Terry

@terence20001 yesss.. caged roller's is what i used after hours of trying refitting the needles ;] you should see my happiness when the guy at the shop told me that such thing exists! ;] that was years ago - when i was 17 or so, but i've learned my lesson the hard way... cheers!

[terence20001]

Hi , Same thing happened to me , it was 1985 i was about 24 at the time . I'de taken cylinder's off so next was what i thought was the easy part :-) but i did'nt know at the time the small end had loose roller's . Like you i was very happy to know they could be replaced with caged type . All the best Terry

i've read in the manual about aligning the twin crankahft with a cupper hammer.. how can a crankshaft, which has to cope with a lot of power, be re-shaped with a small hammer??

[terence20001]

@enfielddnepr Hi , Whenever i change conrod kit's or the centre main's on these crank's . I have it done by a speicialist . I could'nt tell you if they use copper mallet's . I'de like to think they were tighter than that . Cheer's Terry

Hi Terry, You've really improve this, It looks so easy to use, and is an excellent idea.

All the best John.

[terence20001]

@jamsidedown59 Hi John . Thank's . I must admit this is my favorite tool for the Jawa engine . I learned the hard way :-) in about 1985 with my first Jawa . I ended up with loose roller's down the crank case , just about every where . I've never forgotten the experience , my heart droped to the bottom of my stomach :-) Thank's john , im realy pleased with the way it's developed . and it does make the job easy . All the best to you . Terry

@pulse0000 Thank's im pleased with the way the tool has developed . And thank's for your positive comment . Cheer's Terry

[terence20001]

@PixelKlaus Im pleased you like this tool . It is one of my favorites . 25 year's ago i wen't to do what i thought was a simple task . I removed the piston off my Jawa ,and the loose rollers wen't every where . I had to strip the whole engine . It was this experience that made me develop this tool . . All the best . Terry

[terence20001]

@PixelKlaus Hi Klaus . I don't use high temp greece with this application ,as the greece just serves to keep the loose rollers together during removal . Once the engine is running they will automaticly be lubed with the two stroke oil . Thank's for this question , it's a good point . Cheer's Terry

[Bill1960D]

Looks like a hefty crank for a 350.. very cool bikes

I dont think Ive ever seenone.

[terence20001]

@Bill1960D Hi Yes i agree they are a large and heavy crank on the Jawa C.Z. 's I've got a Jawa 250 single cylinder aswell and the crank is evan bigger . I think it help's with the torqe . Cheer's Terry
