skelly Posted September 9, 2016 Share Posted September 9, 2016 Hi. I wonder if anyone can tell me the width of the gear clusters as fitted to the input shaft please ? My katana one measures 111.5mm My EFE one measures 112.5mm Is 112.5mm correct or has it been pressed together wrong ? Cheers. Skel. Quote Link to comment
Duckndive Posted September 9, 2016 Share Posted September 9, 2016 EFE one is longer the input bearing is different on the EFE shaft....if I remember i can dig one out to look tomorrow 1 Quote Link to comment

Don't seam to have an EFE one handy at the moment I assume you have both shafts for the EFE set ? Have you tried them in the cases ? 1 Quote Link to comment
skelly Posted September 10, 2016 Author Share Posted September 10, 2016 Yep 111.5 is correct. And looking at my input shaft I can see the problem. 2nd drive gear has not been pressed on far enough. So now I'm wondering... Do I just press it on a further 1mm Or do I remove it and re loctite it and press it back on... Hmmm Quote Link to comment
coombehouse Posted September 10, 2016 Share Posted September 10, 2016 I thought it was normal to have 2nd gear welded in place to stop it spinning under load. Once it's in the right place of course. Quote Link to comment
skelly Posted September 10, 2016 Author Share Posted September 10, 2016 @coombehouse I'm not sure about welding it on. I think it would create more problems meself. Anyhow. Just had me shaft in me mates press. Had 8 tonns on it to shove the gear on a bit further and BANG... It went too far even though I used a stop. So now I am feeling very very annoyed. And have to pull the gear off and start again or get another input shaft assembly. I'm in a really bad mood now... Quote Link to comment

coombehouse Posted September 10, 2016 Share Posted September 10, 2016 Who is they & why did they stop. I have 2 gear assemblies. One in bike & a spare set. Both have been welded. Never had a problem though back in the day with big motors & nitrous 2nd gear spinning was always an issue. What has changed or have all got older & slower. I know I have. Quote Link to comment

skelly Posted September 10, 2016 Author Share Posted September 10, 2016 There is no shoulder for 2nd gear on my kat or efe input shaft. Im sure its 2nd gear. Its the one furthest from the clutch just inboard of the bearing.. Bloody thing.. Quote Link to comment

skelly Posted September 10, 2016 Author Share Posted September 10, 2016 Im not sure about 5th gear bush. My main problem now is that my gear cluster now measures about 110mm and the gear next to 2nd drive gear is now stuck. Arse. Quote Link to comment
Duckndive Posted September 10, 2016 Share Posted September 10, 2016 Does your press not have the narrow / thin plate,s that you can put behind the gear and press on the shaft to move it i have complete gearboxes if your desperate , but poss not cheapest solution Quote Link to comment

Im gona machine a boss to go over the end of the shaft that is the correct thickness to give me the overall size I need when its pressed again. I'm just cautious that its not recomended to move these gears too much. 1 Quote Link to comment

skelly Posted September 10, 2016 Author Share Posted September 10, 2016 Just noticed something else. My original katana input shaft is hollow all the way through which means that oil will be pumped all the way through and come out inside the clutch. The efe input shaft is solid at the clutch end which means that oil will be pumped out of the small holes along the shaft only. In my mind this is better for the gears and better for overall oil pressure around the head etc. However.. Will it cause a clutch problem due to less oil going all the way through the shaft and out the clutch end ? Quote Link to comment

Gammaboy Posted September 11, 2016 Share Posted September 11, 2016 EFE is a the newer development - they obviously worked out that the cllutch didn't need the extra oil the Kat shaft was delivering. 2nd gear welding is a good idea - when I put mine together, one box had spun and friction welded 2nd (couldn't get it off with my press), the other had spun 2nd and it came off far too easily...

skelly Posted September 12, 2016 Author Share Posted September 12, 2016 Apparently there should be an alloy bung in the end of the katana input shaft, so the effect is the same for both engines. Also the oil flow schematic does not show oil flowing out the end of the input shaft, so I'm happy to use the EFE one. I'm not going to weld my 2nd gear to the shaft. firstly because it is f*****g tight, it took 8.5 tonnes pressure to move it 1.15mm Secondly, I'm not running a turbo or nitrous or mad power outputs, if I get 150 HP I'll be surprised. I just can't justify it.. However I totally get it on high output engines. (you watch, I'll be back on here next year,, 2nd gear has spun etc lmao) Cheers. Skel Quote Link to comment
coombehouse Posted September 12, 2016 Share Posted September 12, 2016 I guess you won't be using a billet back plate on the clutch basket either? Quote Link to comment

Gammaboy Posted September 12, 2016 Share Posted September 12, 2016 Well, given that they'd both spun with maybe 110hp, I'd say it's a real crapshoot. Quote Link to comment

Not got to the clutch yet. The word is that a billet backplate is not really needed with straight cut primaries. However, You never know. My first concern is getting the cases together and I'm still struggling with this stupid input shaft. Can any of you post a photo of a welded 2nd gear plz ? Would be interesting to see where and how much etc. Cheers. Skel Quote Link to comment
