Thanks for the answers.
Belt: I've seen where some one replaced the belt with out checking size, width etc. I have also seen where one shredded a belt and did not remove driven and clean debris and check seal and lead to failure.
Yes was making sure the shafts we're parallel or slight obtuse from the case.
curious if the
Engine transmission was tied together solid allowing the
motor ((
Internal Combustion Engine ? )) (( Internal Combustion Engine ? )) mounts and transmission mounts to work in unison.
Concerned about shaft Center and belt Center numbers.
I would consider removing the driven spring and the drive spring reassembling the clutches on the rebuilt transmission checking your Center to Center and run outs for the belt used.
this could contribute to bearing failure and or cracking the Engine mount.
Just some thought since I have never seen or worked on this combination.
if you decide to remove the driven spring also check all the roller bearings in The driven.
if you do remove the driven spring check it to make sure it's within spec or shim for correct poundage.
This could and will affect the load on the drive.
Few years back I posted a driven spring correction chart
The last thing you want is the drive to outrun The driven this lead to bearing failure. That is to say driven bottomed out and drive still expanding. If so you need to shim driven or take away from drive. Your rpm range will help with that.
That is where center to center plays a part. Once the driven locks out in the drive expands it takes the parallel shafts and makes them acute. That's where you'll see the stress on the bearings. with a new belt this is more crucial than already a stretched belt that is adjusted to this situation. V about where and stretch.
The angle we're on the Bell will be a Tell-Tale for this.
You will need to log the new belt and then check it then compare the difference. If there is this will impact we're on the drive in the driven until it wears to an acceptable level.
The belt I removed had not totally self destructed, just had a strand of Kevlar that I heard whipping around, I'm hanging onto it just in case I'm down to my last belt on a trip and need something I can limp back to camp with. While I have it apart I'll disassemble the clutches and service.
I'll check the alignment before reinstalling everything, the Engine and trans are tied together with the Engine mount so the assembly is using the two front stock Engine rubber mounts as well as the 3 transmission mounts.
Do you know of a thread that explains checking the center to center run out? I'm thinking I may replace or duplicate the Engine mount and will want to make sure it's right.
I'm using the rotax clutch, it has been modified to use the narrower Pilot belt. I do have lots of information on the driven clutch and it's operation and tuning so I'll be sure study up and check that out as well.
how to check to see that I don't have the "out run" situation?
Thank you for the the assistance as well as everyone on this forum
