Is it ok to use Motul transoil SAE 10W40 in the gearbox of my 360 sidepipe 1969, also does it have a dry or wet clutch
cheers Pat
-
Should be okay to use the motul, should be a dry clutch unless someone has done the conversion to a wet clutch setup.
Easiest way to tell is look at the underside of the small cover & see if there is a small cutout along the base, this needs to be filled in to allow the sidecover to seal for the wet clutch conversion

Hi,
I have been using Castrol VMX 80,in all my CZ's since 1968, seems to be quite good,
thats what the CZ riders manual recommends,
Are you using 20: 1 fuel to oil mix?
cheers
-
i run the same as above, all our cz's run fine.

All of my CZ 250/400 Three wet and two dry clutchs run Castrol MTX80 gearoil for over the last 10 years plus
Can also run the same oil in the front forks same as SAE30
Dry 650cc
wet 850cc
Cheers

Thanks for the info, will now be able to change gear oil, and yes i am using 20:1 ratio seems ok but still need to sort out a few tuning problems.
cheers Pat
-
i use the same as mr bamford.all good
-
Just out of curiosity, you guys mentioned that your oil and fuel mixture
is at 20.1 .....
Soooo how much oil would you mix in with say 5 litres of petrol and which type of oil ???
Sorry if im offending anyone by hijacking this thread but this info is valuable to me
as i own a CZ as well... :)

250ml to 5 ltr
Maxima 945 castor

Bit off topic...
Just drained the gear oil out of my CZ400 and only got 50mls ?? WTF is going on ..
Do they chew a bit of oil or is this normal ???
Been told to put in 500ml of castrol mtx 80 is this the correct amount.
Bit confused any help much appreciated.
Cheers Andrew

650mls is normal for the dry clutch
Very much doubt that the missing 600mls will be sitting in the primary drive casing, you normally have to lean them over when draining to get all the oil out. The reason being that the cases are not drilled at the lowest point which I assume is to keep more oil around the gearbox & less creating drag on the primary drive gears, the plate with the hole in it between the crank & gearbox input shaft is where the oil comes through
Lean the bike over with the screw that is generally mistaken as being to check the level removed & see how much more you get out, there is really only 2 places you could be losing oil, crank seals or into the dry clutch cover.
First place to check would be the clutch seal, pulling the cover over the clutch will tell you whether there has been large amounts of oil in there

Andrew, change the crank seal. That thing is sucking in oil as the oil was changed just before you bought it.
-
Tony,I have mistakenly been using the primary drive drain bolt as a level to check the amount of oil in the gearbox.How else can this be done?
-
I just measure out the correct amount when changing the oil, draining all the old oil out is the tricky part.
Have found the easiest & quickest way to refill the gearbox on a 4speed motor is to remove the top cover, as a bonus it gives you a chance to give the gears a quick check over
-
Yeah,I measure what I put in but never really take any notice of how much comes out.How often do you guys change your oil?
-
Before i go changing the seals and pulling the motor apart what sort of special
tools will i need besides the flywheel puller.Can anyone give me a quik heads up.

Hi Andrew,
you wan't need a flywheel puller as the flywheel is on the air side and will not be sucking oil
you may need a normal type 3 prong bearing puller to remove the primary gear on the left side after you have taken of the clutch and primary driven gear.
You may also need a clutch spring remove tool.
where are you I can lend you these if needed
good thing is you do not need to split the cases.
try here to help you through.

I guess you're thinking if 1 seal needs doing then may as well do both for peace of mind.
You won't need a flywheel puller for the primary drive side unless the bike has a full circle crank rather than the later pork chop type.
The whole job isn't a biggie & is easily done with the motor still in the frame
VMX unlimited has the tools if you decide you need to own your own set
-
Actually just had a brain fade moment,
on side pipe CZ primary side gear uses same puller as flywheel, maybe not needed but easy, not sure if this is same on later models,
have a puller you can borrow anyway.
