Clutch, pilot bearing, rear main seal

[rylee144]

Ah I see an xj newer than mine

[87MJTIM]

Yes. 89 1/2 or newer or if a PO swapped an AX15 in place of a BA10.

 

What is your current trans, BTW?  Not sure? The BA10 splits in half from front to back, so the case open lengthwise.  AX15 splits in circumference around the case.

[rylee144]

It's a ba10

[rylee144]

Just to confirm auto and 5 speed cross members are different? Found this one from an auto

[87MJTIM]

That's correct

[rylee144]

Nuggets, thanks.

I ended up getting the pilot bushing in the link above. I also picked up a new clutch kit. The new kit has 2 bearings where does the gold one go if it didnt come in the kit? 

[BeatCJ]

You would use one or the other. The early crankshaft has a smaller bore than the later.model. Do I see a needle bearing the same size as the oilite (gold) bushing? If it is, and it fits both the transmission input shaft and the crankshaft bore, a bearing is a superior setup to a bushing.

[rylee144]

I pulled the pilot bearing it was smaller than the one that's needed now. The two on the left came out. 

 

The one on the right is the one that came with the clutch kit. It fits the shaft on the ax15. It's wobbly in the pilot hole. The gold ring also fits the shaft on the trans but not in the hole on the motor. 

 

I'd like guidance if I could get it. Thanks.

Also got the oil pan dropped and the rear main seal housing. It looks a little scored up.

What does the surface feel like?

[rylee144]

I'll get a picture tonight but it didnt look bad at all,I was surprised 

[rylee144]

Might order this and see if it works.

looks good and broke in. clean it up fresh seals and run it. add a little grease to the needle bearing one. when it warms back up next week ill be where you are currently. so appreciate you sharing whats ahead of me, again. 

[MiNi Beast]

i used a bronzed bushing as had small tip ax15 and big hole 4.0. 

worked great after 5 years i had to replace it as it did wear funny. but maintenence free and reliable and thats what we are all after. 

[rylee144]

The bronze fitting I have fits real tight. Maybe it just needs greased and tapped in. I'll have to take another look, otherwise it's to Novak route. The new seals should be here tomorrow

They also have a universal ax15 mount that can adapt to your crossmember with a little work.

The scoring on the journal doesn’t look bad but it’s always very hard to tell from pictures. Not to much work to pull the crank though at this point. Definitely recommend replacing the rear main anytime your that far into the engine and it has more than 100k or so on it. 

[rylee144]

The rear main seal should be here anyday now. Then i need to figure out the pilot bearing situation then I can re assemble!!!!! Getting excited. Still lots to do.

Sweet! The pilot bearing you need should be an off the shelf item at the auto parts store.

I’m assuming you have a 3/4” snout on the ax15 going into a renix 4.0 crank?

Yes. I thought I had the right thing but it's really tight. I need to get a micrometer so i can double check

[BeatCJ]

Really tight where? It IS supposed to be pretty tight in the crankshaft, but should rotate easily on the input shaft.

 

FYI, if you end up using the bronze/oilite bushing, that does NOT get greased. It is supposed to be soaked in motor oil, and off the top of my head, it's recommended that the oil is warmed to about 130 degrees.

[rylee144]

Thanks for the no grease tip, I read that but I could use all the reminders. This hole
