Hi guys. I have never put a gearbox onto a motor before. So I'm after some advice. Do you put grease on the shaft where the through out bearing goes. And do you put grease anywhere else. And also if you do, what type of grease. Ian.

[Rockoz]

We used to use normal wheel bearing grease.

A bit on the shaft where the throw out bearing moves, and a bit on the spigot end of the shaft.

A bit in the groove where the fork runs as well helps reduce noises.

You dont want to use a lot as it can cause some issues with the clutch plate if there is heaps in there.

 

Cheers

Thanks Rob. Anything on the plastic speedo gear.

Speedo gear is lubricated by the box. I would just wipe oil on the o ring so it doesn’t get pinched on installation Ian.

Thanks again Rob and Clay. My car is not far off now. After 27 years off the road. And 3 years for me to rebuild it. I could not have done it without the help l have received from this forum. Thanks everyone who has taken the time to help me. This forum and you people are the best. Thank you.... Ian

Will you be taking it to Toranafest mate,

You should soak the spigot bush in ATF overnight  before installing and check carefully that it is the correct depth. This is best done with engine and box out of the car. It should support the tip of the input shaft without binding.

 

It helps to have a clutch alignment tool or spare input shaft as you are installing the clutch. If its mis aligned you will never get the input shaft through the clutch.

Will you be taking it to Toranafest mate,

no Col, just can't make it. I have to join a Torana club (for rego). Get an exhaust made. Just learning what to do with gearbox to motor at the moment. Everything has been a learning experience. Pretty rewarding though.

Thanks Rexy. Not sure what the spigot bush is. But I will google it lol. The clutch is on the motor and it has the alignment tool in it. When you insert the gearbox do you rotate back and forth to seat it ?. The motor and gearbox are still out of the car.

If the engine you are fitting was formally from an automatic car, it will have different spigot bush that you will have to remove to fit a manual one.

[IanC]

Same motor and gearbox. Both have been renewed.

[claysummers]

Normally you would get a new spigot bush in, I think, the gearbox overhaul kit?

Check the old one is still there. If so check the gearbox bolts up ok without the nose of the input shaft binding. You will need the clutch removed to be able to see how deep the input shaft spigot enters the bush.

 

There is probably a clearance that the old boys can tell you. With the custom setups like the Toyota boxes to holden V8 I usually allow about 1.5-2 mm.

Hi mate,

 

Is the engine in the car yet?

&

Are you working on the floor, on a hoist, or are you assembling the eng/gbox/Kframe as a unit ready to lower the car  over it all?

[IanC]

Thanks everyone for the replies. Engine is fully rebuilt. Gearbox rebuilt. Brand new clutch already mounted on the motor. Yes Col I am going to lower the car onto the motor and gearbox mounted to K-frame. Any tips would be great. I was just having trouble finding what gets grease when you bolt the gearbox to the motor. Any gaskets or RTV sealant?. Any help is really appreciated. Thanks again Ian.

[RallyRed]

All good mate,
I was just going to say I sometimes just test the gearbox shaft into the end of the crank.
Then fit the clytch, test again.
Then fit the bell house, repeat the test fit.
That way if you have dramas you know exactly which part is the drama.Takes very little time to do it step by step.
Also as you may know, ( when bellhousing is not fitted, and you are test fitting,dont let the gearbox hang off the motor/ clutch as the weight of the gearbox may 'tweak' the clutch.
2 cents
Grease = sparingly, as there's clutch dust just waiting to stick to it

[IanC]

Thanks Col. Really appreciate any help. Must admit I knew/know bugger all about building cars. But I'm getting better. Blows me away how many parts are stamped with numbers. You find them everywhere.
