Hi fellows,

I have to replace my clutch soon.
What is the most time saving/ efficent way to do this?

1. move/lift the engine (with all other procedures, eg. remove radiator...)
2. disconnect/move the transmission/transfer unit (with all other procedures eg. disconnect prop shafts...)

Other questions:
I want to change from the original 8 1/2 clutch to the stronger 9 1/4 clutch (I do some plowing in winters). This swap should be possible, right? What parts are needed for this swap?
- 9 1/4 clutch
- 9 1/4pressure plate
- 9 1/4 flywheel (as the 8 1/2 flywheel has different bolt diameters)
- have fork, throwout bearing also be changed to fit 9 1/4?
- any other adjustments?
- will the 9 1/4 flywheel work with the starter (toothing)?


I appreciate your help and advice,
thanks,

Philipp

When I have a hoist (lifts entire jeep) available I will use a tranny jack and pull the tranny/transfer assembly.

When I do not have a hoist available I find it easier to remove the engine without the tranny/tranfer.

You did not tell us what model jeep? If M38 you did not tell us which flywheel you had 122 or 129 tooth?

In either case you will need the correct tooth count with the wider diameter bolt holes for the 9 1/2" clutch.

Hello Wes,

nice to hear from you.

It is a M38A1 jeep.
What is the conclusion then?

Other question:
I think I will see an oily bell housing... if the oil comes from the engine, how is this sealed properly?

The oil leak issue makes removing the engine from the jeep the better option for you. With it removed you can better address the leak issue which if engine oil will be from either the rear main seal or the rear cam journal welsh plug. In both cases flywheel removal is advised. If it's the rear main seal have the engine on an engine stand so you can invert it and do a proper seal replacement.

If you have a 129 tooth flywheel as you should then hope you have both sets of clutch bolt holes as the civvy jeeps do. Both 8.5" and 9.5". If not then you must search for a civvy 129 tooth flywheel.
