Mating the bell housing, any tips? (5 Viewers)

[sodafeld1]

I have the trans close to 1 inch to the block. everywhere I have read people say don't use the bolts to bring it home. Gear box is in neutral, have turned the crank a little, used an alignment tool. At one inch it does not wiggle anymore.
It has a heavy duty clutch installed, depressing the throw out bearing lever helps a little.
I have used a scissor trans jack below and an engine hoist to adjust the spline alignment on the trans. Engine is fairly level , but raised at the front as per advice.

Have not reached the guide pins, but it feels close. I have used longer bolts just a little tight creeping in in star pattern around the bell. Not forcing it, terrified to do that.

Can only find one video of the h55f mating to a 2h on 40channel , he still used bolts once the guide pins got wiggled to.
Any advice? tips?

Another pic, open to criticism besides being messy.

Make sure they aren't cock-eyed at all.
If the faces of the bell housing and the block aren't almost perfectly parallel, the input shaft will bind.

Once everything is parallel, there's no problem using the bolts to pull it together.
If something is on the piss and binding, using bolts will do damage

Yes approaching with caution. Jeez look pretty straight. Has to be up there as one of the most under appreciated jobs for mechanics.

It can be infuriating. I've wrestled with them under the truck a few times, wriggling, levering, prying, pushing, swearing, and suddenly they just slip together!

Try rotating the engine a turn or two as well. It might help get shafts and splines aligned

That is what mind blowing! hard enough out of the truck

Mmph, can't turn the crank much, so must be binding. Have undone 3 times now and started over..here i go again...

I have seen where the plastic clutch alignment tool will flex and sag slightly under the weight of the disc in some applications. So it's not truly centered as you are tightening the clutch bolts. So I got in the habit of holding it up while tightening the bolts. I never had that problem using old cut off input shafts as alignment tools.

Might not be your problem, just throwing it out there.

mmh, another good point, she slipped in easy..I am going to loosen it off and out a bit, using 2 more bottle jacks and keep spinning crank whilst slowly going back in after lunch..

 

[sodafeld1]

lunch is important too

Did you confirm that pilot bearing slips on to input shaft before it was put on the flywheel? Sometimes you need to emory the input shaft snout a tad. Take bell housing off and confirm this by trying to install snout into bearing

That is another good tip. Thank you. Think I am making progress by turning each bolt two turns with virtually finger strength in star pattern and rotating crank each cycle. Lifting front of trans a bit is helping. When I reach the pilot I guess I will find out, as no I did not check that. Learn from experience.

I learnt the hard way as well... dont be afraid to take it back out and clean up that snout. You are correct to avoid using the bolts to draw the trans in.. very bad thing to do.

Rotate the trans back and forth with some force encourage it forward.. it will eventually pop in.. but if the input shaft has a tiny bit of corrosion on it, it will really bind on the pilot bearing.

yup, couple drinks and a bit of a tickle and a smack and youll be at home base...

 

[sodafeld1]

Hoobloodyrah!!!!!!!!!!!! Actually somewhere back in the fuzziness of my memory maybe I did check the bearing fit the shaft. Thank you all. Little satisfying win for me today, being a virgin and all.

Got to say, ih8mud is one of the best things of the internet. Most of the internet annoys me, it causes divide in society. It makes people anxious. Makes them dumb consumed with dopamine and distractions.

Whilst Ih8mud is a brilliant resource which taps into the vast experience of fairdinkum wizards for free. Great guys!
I have learnt so much here. Wouldn't know a fraction about landcruisers if it wasn't for mud. Beautiful thing.

Paying it forward is a beautiful thing indeed.
