I'm trying to bolt my motor up to the bell housing and am about 3/4" to mating. Would you guys pull it together with bolts at this point or wait until the giude pins are started. I just can't seem to get it any farther without pulling it together with the bolts, It's mating to an M6

 

im not going to recommend that..you could break an ear off the transmission housing... are you sure the clutch and pp are aligned correctly..if not, the splines will not line up... did you use an alignment tool to verify you were lined up correctly?

 

Ya I used an alignment tool on a Mcleod Street twin, So these should slide easily up to the dowel pins?

 

I have never seen or heard of an alignment tool that actually worked. People usually use a spare input shaft. Thats what I am about to use. The tool that came with my kit, like the ones that come with many other kits, does not align the components right.

Maybe yours is different though, but again I don't know of any that come with clutch kits that have worked. You could check and see if everything is aligned.

 

NEVER pull an engine and trans. together by tightening the bolts. Something isn't piloting correctly. Are you sure nothing is in the way ie. wiring harness, conduit, etc? Why was it apart? If you just installed a clutch or pressure plate compare it to the original, does it look the same? Same finger height? Is the input shaft correctly piloted into the crankshaft? Make sure nothing is in the crankshaft that is bottoming out the input shaft. Did you dry fit the clutch disc on the input shaft before you installed it? Maybe the splines are dragging. Try a very light coating of lithium grease on the splines. If you aren't sure about the clutch disc alignment, have someone slowly press the clutch pedal when you are at the point it will not go, this should align the disc to the input shaft. Good luck.

 

kjlvilla , I know that the mainshaft splines are through the clutchdisks because if I put the car in gear I can't turn the crankshaft, It's about 3/4" to 1" from mating up which I think is where it starts to go into the crankshaft. I'll give it another try this morning, I really don't want to yank it back out. I can't put the clutch pedal in yet because I'm not sure I've bled all the air out yet. Can you put the clutch fork in before the block & bell housing are together? The reason it was out is I'm dropping in a new 383.

 

After 12 hours on something that should have took 1 I finally mated engine to bell housing. I had to put motor on engine mounts then undo back trans mount. I had about 3/4" to go and couldn't get the POS together. Finally after pushing in the clutch fork and releasing the clutch it popped in, Must of been slight alignment problem. Just posting this incase someone else has the same problem with a Mcleod Street Twin

 

Yeah. Same thing happened to me. What it was is that the front end of the shaft wasn't centered on the pilot bushing. I have had better luck centering the clutch disc with my figers with the allignment tool in place and then tightening up the pressure plate. The allignment tool just isn't as accurate as usint an actual shaft.
