Type R Gearbox Syncro problem...Any advice?

[cad843]

cad843,
usually crunching problem w Honda gearboxes r mostly caused by sychros......& to untrained eyes,usually u won know wat's wrong or whc synchros is spoilt..leave 2 a competent mechanic.....

I will send over to experience mechanic later to check my gb, but Im planning to change together with release bearing. Any advise for other wear & tear parts inside gb that I should check together? 1 more thing, that copper ring can be change or not?

 

[akuma]

wat copper ring?AFAIK,whn u buy brand new synchro,they come as a set...whc means 2gether w d copper ring(if v r talking abt d same item)...basically,nothg much in d gbox except 4 d ratios,shafts,synchros,bearing,forks,magnets......wat need 2 b changed depend on ur mechanic's inspection n how much u trust him.oh yeah..1 advise....while d gbox is open,kindly remind ur mechanic 2 clean d inner part of d shafts(usually by pumping fresh oil 2 force any dirt/grime out)....MOST shops i c dat fixes gbox don do dis....gd luck

and while ur gearbox is out..its a good time to upgrade/change ur clutch if u need to...

also a good time to be installing LSD if u dont have one.


still got 2L MTF-III left... will be using that in another 9k km....then mebbe ill give the redline a try....

 

[akuma]

woi..dun play d while ur at it game ler wei.....coz it'll b a never ending story..hahahah...so,y not while ur at it.....experiment w all d aftermarket ratios available(ATS,KAAZ,JUN,SPOON,etc frm 1-5).....hahahaha..koyak d poket!kekekekekkeke......
eh,wat's d service interval 4 MTF-III?

 

[mADmAN]

LOL.... poket koyak boleh jahit maaaaaaahhh hahahahhahahahahahha

MTF-III around 20k if not mistaken... typical for gearbox oils

but im the type that changes every 10k

 

[akuma]

of coz pocket koyak can sew back..but whr's d "refill"?hahahahhahaha

 

[mADmAN]

itu kena slow slow jahit and refill la.... which is what im doing now ha ha ha ha ha

Sil80-13,
IF d crunches does not go away after 2-3 days of normal driving,thn i guess ur in big trouble.no choice but 2 open up d gbox n inspect...BUT since u mentioned d crunches now only happen during high rpm,shudn't b dat serious.....

maDmaN,
i'm not sure abt Hizam's case but every1 dat i've suggested using dis gear oil 2 solve d crunching problem all came back happy.....n i had d chance 2 compare btween MTFIII vs Lightweight Shockproof almost back 2 back......i'd say Red Line gives me better shifting whc is more precise compared w MTFIII.....but i must say MTFIII is good too...just too bad i had a mis-shift incident n had 2 switch 2 Red Line.....

akuma,

Normal driving no problem at all. But when I try again with high rev shifting from 2nd gear to 3rd gear, no crunching sound already...Also dont know why. Anyone just bought Red Line Lightweight Shockproof gear oil from Kakimotor. Will change & test it when the next RCA track day....

I already placed an order for few g/b items fr Japan with assistance fr 1 fren that staying there. Hopefully my g/b project can complete bef end of this year

 

[akuma]

so,wat haf u ordered frm Japan?not available here or price difference too much?care 2 share?

Few of new gb parts only, I dunno whether not available here or not but the price of coz a bit higher la but confirm new and ori including clutch set. As u said, it depends on pockets, so I order parts when $$ enough lerr. When all parts buyed already, will ship 1 shot

okay so here's my story about the redline lsd gbox oil (also called the blue gel one right?).

before this, i was using a 4.7 type R gearbox. got crunching sounds during high rev. so a friend of me recommend me to use the redline oil. after a few days of break in, yeah, the crunching sounds was gone. but then maybe it is my mistake of using it more than 10,000kms, the gbox is starting to make the crunching sound again.

okay then i change to 4.4 eg6 gbox. pour in new redline gbox oil and everything was working good. but after three days, suddenly the gbox made the crunching sound. and now suddenly i heard people are saying that the oil is no good. so then i change to lucas, but guess what, now not only high rev, low rev also dia crunch. i can say that for the time being i'm so fed up with gbox issues. i really really really miss my eg6 old gbox that was originally equipped to the car. it was a mistake changing it to dc2 4.7 gbox when it doesn't give me any headache.

mind sharing the crunching sounds during hirev is at which gear? 2 to 3, 3-4.... before u had the problem with the crunching sound, did u had any miss gear that may lead to the crunching sounds? anyway, what is the status of your GB now?

 

[zNiPeR]

experienced this myself: 2nd to 3rd gear got crunching sound, initially during high revs and soon after that even in low revs oso got crunching sound(was on motul 90 PA LSD oil).....then open the gearbox for inspection found out it was a synchro problem....bcoz i'm to poor to buy new synchros, my mech offered to clean every single parts inside the gearbox and pour a fresh redline's lightweight shockproof LSD oil....walla! no more crunching sound even during high revs!

the downside is, it's quite difficult to engage 1st or reverse gear early in the morning, so my opinion is; allow the oil to warm up first before shifting during high revs (jgn test machine lps kuar dr umah)....bcoz visually u can see how thick is the gear oil if u compared with other type of gear oil...it may need some warming up before the suitable viscosity is achieved.....

how much ur mech charge u for the cleaning? where is the workshop located? tq

it's been 2-3 years since i've overhauled my gbox....can't recall but usual labor charge wud be around RM150 to 200 to overhaul gbox...the workshop is Speed Tune Autoworks(Din)....now in front of Tesco Ampang.....

is it the same Din or known as Din Pendek (the shop used to be at Danau Kota (behind EPF)?)

1st GB, ori eg6 with LSD. no problem. during this time i wasn't sure what GB oil am i using.

2nd GB, 4.7 Type R LSD. hard to engage 1st gear and 5th gear. from 2nd to 3rd, 3rd to 4th, and 4th to 5th will make the koko crunching sounds during high rev. waste my money only to buy this GB. wasn't so sure what GB oil at first, then change to redline blue gel. solved the crunching sound but later it was making the damn sound again.

3rd GB, another ori eg6 LSD. use redline blue gel. was OK for first 3 days only. then the same. 2nd to 3rd, 3rd to 4th, 4th to 5th. crunching during high rev only. change to lucas oil but the situation get worst. now during low rev also got crunching sounds.

the status now? ahh... f**k the GB man. no money also to fix. fed up also to fix. i'm getting married la. have to pay for other much more important things la.

but maybe i would like to try to flush the GB, then use back the redline oil. what say u?
