my box is noisy as f**k when hot, but its a weird noise, i suspect synchro's, it only does it when rolling fwd in neutral, like down a small incline, clutch in, still noisy, push the stick towards any gear, it goes away, been doing it since i bought the car (2 yeras) so its not terminal (yet)
the oil was not twilight stylee (sparkly) or dirty, so i ruled out bearings machinging the casing.
as a fun project i bought one of the many 1st/2nd gear fail to select boxes off ebay
its a bit of a punt but so far look good
oil is clear,
input shaft and diff are good and solid, still plenty of preload
pulled the shift tower over the w/e, found a nice clean break on the rivit and the selector sitting in the bottom of the box
a couple of slight bruises where it had contacted a gear wheel, but clearly had not been digested by the gears
the gears i can see look good.
i will have a good look when i split the box.
i hope to do something regarding measuring preload that should help others ,and also on getting the box out
most guides are a bit blue peter ish, - undo all the bolts and heres one we did ealier!
i can see what bolts to undo, its the actual moving the box around that missing.
i have a trolley jack and will make up an adapter in wood to balance the box on the jack
i was thinking about making an engine beam, but have seen a pretty good one on fleabay for about 50
Gearbox stuff is thin on the ground tbh... bit of a black art too it seems...
Need to strip my box and replace the the diff bearings plus do the selector fork mods... I also have a crunchy 1st > 2nd change which is syncro/baulk rings... expensive if the syncro unit is fecked but I am looking at getting a low mileage 02M and swapping internals over... 'easy enough' to do in principle but there are differing ratios to consider... doing a little research at the moment to see whats what
