Operated sweet before. it’s rotates about a foot or so If your getting some movement it wont be in two gears. Then it would be locked solid . Drum brake rear end? Could the handbrake be binding?

shizzl Posted September 13, 2022 Share Posted September 13, 2022 Definitely not brake related, that’s what I suspected first off. But spins fine when jacked up. Quote Link to comment Share on other sites More sharing options...

Well I guess you answered your own question The only thing between the driveshaft and the flywheel is the gearbox. And if it all spins fine when jacked up then the diff will be ok or youd feel it. 1 Quote Link to comment Share on other sites More sharing options...

Maybe if it's not a 10mm socket then that rag from @cletus oil pump drive is in there. Perhaps jack the car up noze down and start it up with the driveshaft removed from the gearbox? Shouldn't be too much spillage from the output shaft for a quick check. 2 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted September 13, 2022 Share Posted September 13, 2022 Could be a collapsed countershaft bearing. Rotates a tiny bit then jams. Quote Link to comment Share on other sites More sharing options...

What do you mean it spins fine? Can you fully rotate the driveshaft by hand with the gearbox in neutral? Quote Link to comment Share on other sites More sharing options...

Yes you can. clearly gearbox internals. been trying to find any helpful diagrams etc for hours now clutch operates as it should (can’t be pilot bearing issue) diff is fine brakes don’t drag engine still runs with clutch in and in gear.

Mof Posted September 13, 2022 Share Posted September 13, 2022 Can you pick it up, put it in 4th and see if it goes further? Quote Link to comment Share on other sites More sharing options...
Mof Posted September 13, 2022 Share Posted September 13, 2022 I've had a box before where the input shaft had a bit of a whack in and it jammed the 4th synchro onto 4th gear. So it acted a bit like it was in two gears, maybe it had some slack like yours does I can't remember. If it drives in 4th that'll tell you 1 Quote Link to comment Share on other sites More sharing options...
shizzl Posted September 13, 2022 Share Posted September 13, 2022 Right so I chucked in reverse and wound it over on the key, it operates normally. same if put in first. I’ll try it again later tonight after the whinging Pom next door goes home Quote Link to comment Share on other sites More sharing options...
mjrstar Posted September 16, 2022 Share Posted September 16, 2022 In more linisher chat, I don't do much in the way of heavy steel fab work bit do need a way of tickling up a tungsten from time to time.. I find my baby bench grinder isn't ideal and thought that maybe a cheapo belt sander linisher makes sense.. Anyone using one of these poverty machines? Appears to have a few more watts than the one @Geophy linked back a page or two.. https://www.bunnings.co.nz/ryobi-370w-150mm-bench-grinder-sander_p0314864 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted September 16, 2022 Share Posted September 16, 2022 I've got that one (and the bigger belt+disc sander they do), I've used the belt for tungsten a bit in the past and it worked fine, but I've now got a green silicon carbide wheel on it that I use only for tungstens.

NickJ Posted September 16, 2022 Share Posted September 16, 2022 I use a diamond wheel on my dremel for tungsten if budget is the driver? Quote Link to comment Share on other sites More sharing options...
shizzl Posted September 17, 2022 Share Posted September 17, 2022 Replaced the gearbox. got it all back together. done a tune on the engine. go to chuck it in gear to see if it’ll play ball. Nope, same bloody issue. wtaf 1 Quote Link to comment Share on other sites More sharing options...

Yup, diff is free as, can roll the car around easy, spin the pinion flange by hand and cycle it through a one wheel peel by holding each wheel. no clunks or dragging. has to be something in the flywheel/clutch situation. But I don’t understand what it could be. the old box shifts through all gears nicely still . dumb Quote Link to comment Share on other sites More sharing options...
cletus Posted September 17, 2022 Share Posted September 17, 2022 A big angle on a driveshaft u joint and a grease nipple binding up? 2 Quote Link to comment Share on other sites More sharing options...
