5th gear crunch

My last 2 pulsars did exactly the same, and so does this one, if driving with a bit of pace just can't select 5th gear til you wait for revs to drop and slow down a little, why is this? Anything I can do in my driving style to make it work?

Sounds like 5th gear syncro, common fault at high revs... Try double clutching when changing from 4th to 5th at high revs. Worked for me on my old box

hmmm think i may of discovered why it does it now, im getting clutch drag when its hot, i might try some dot 5.1 fluid in the clutch system?

check slave, master & pedal flex too .

clutch drag wont affect 5th gear selection
as gaz said more than likely the syncro in box and double the clutch will resolve that issue

I can't get 1st or reverse either when it's hot, so it's not just 5th

You say your last 2, i have never had a problem selecting 5th?

maybe im a shit driver then haha

but seriously, all 3 pulsars iv had have seemed to crunch into 5th gear if accelerating hard in 4th upto like 6.5k revs and then immediatly selecting 5th gear

3rd and 5th i killed on a couple of my standard boxes hence buying my par and quaife boxes. 20 year old boxes many of what have not had regular oil changes and been abused its as with any car not just R's a gamble. Who is sitting reading this have neglected diff oils on ther R ?

my black r i had i changed the oil in the diff and it came out purple, so obviously previous owner had done it too, but i agree, diff is always forgotten, i gave mine a good engine oil change this week, maybe i will do all the transmission!

Yep good stuff mate. Like i say i have kilked a couple of 3rd n 5th gears

seems like others have had similar with 5th

Mine crunched (not all the time) going into 5th gear from the day I bought it, that was 14 years and 145,000km (90,000miles) ago.
As said, if I change gears slowly it doesn't crunch, but if I am playing rapid and try quick changing then small crunch.
It has never bothered me because driving slowly it is always changed at around 3000rpm.
Can only assume the synchro doesn't spin fast enough or isn't good enough too allow quick changes to mesh correctly.

All fixed didn't realise there was a adjustable rod on the master cylinder, adjusted it by about half a cm and clutch and gearbox is lovely now!
