I have that tool and the Tusk case splitter tool. Bought them when I did my first Minarelli. The puller mostly sits in the box. The splitter I've used more so I can split cases without having to tap on anything to get them apart. Neither is really essential if you use heating and cooling, but not bad things to have around. www.rockymountainatvmc.com/p/3346/17167/Tusk-Crankcase-Splitter-Separator |

You can improvise pretty easily on the case splitter. But the Crank Puller is a sweet deal. I freeze the bearing's drop them into the carters. I put a little film STP on the crankshaft, and the bearings pull right into place. I have used it many time's on ATV & Dirt bikes. They sell some accessory bits for it, on different MC & ATV applications. But what you get in the box will work on most scoots.

I'm trying to get the gearbox together and I've got the input shaft seated in the case with the bearing heated and pressed onto the shaft. The c clip went right on but I'm not 100% sure if the output shaft for the rear wheel is supposed to be pressed into its bearing or not. It seems like it should because it wont allow the gearbox halves to fit together but I'm at a loss on how to do that without messing up the oil seal. The seal for the bearing its self seems rubber or plastic. Is this one you press in by using a socket and the wheel nut? Or is it supposed to just slide into place and something else is out of whack in there?

I haven't had to press the drive shaft in. The bearing you'll have to seat with the hot/cold method or driving it with a socket.

 This reminds me of NASA in the 80's. Almost the 70's really. |

The bearing was already in the case. Is it possible it was too far into the case? The oil seal and the bearing for the driveshaft were both in and looked like they have been that way for a while. I want to say its about a 1/4" gap between the engine and the gearbox if I test fit with only the driveshaft in place.

drive.google.com/file/d/0By2rcNqfITkKdVV3YW1JVHkyVlk/view?usp=sharing thats what the case is doing when the output/drive shaft is in. I'm uploading the other pics as we speak. I checked and the bearing on the engine and gearbox side for the driveshaft are in as far as they go and up against the machined surfaces. I'm almost thinking this isn't the right driveshaft for the gearbox that came with this case. I really dont want to try and Frankenstein my old gears and these ones together incase they aren't the right types either. That would be my luck lol. drive.google.com/folderview?id=0By2rcNqfITkKS2kyM0RpaGhSeXc&usp=sharingThats the pictures of the other gears in place and the bearings and fitment of the driveshaft.

Measure the bearing ID and the race on the shaft.

Well idk how much I trust my digital caliper anymore one side measures a little different than the other one does but its consistent readings. The race on the driveshaft measures 20mm od and the bearing in the gearbox case measures 19.76mm id. The engine side bearing measures 14.82mm id and the side of the driveshaft that slides into that is 15mm od. The id measurements were taken with one side of the calipers and the od was taken with the other side. It seems to be about .20mm different between both sides. The driveshaft its self is about 144.50mm long tip to tip.

There's also a larger ring on the driveshaft that stops it from going into the bearing on the gearbox case bearing that measures 25mm.

If the OD of the shaft is larger than the ID of the bearing then that's a problem. IIRC the larger part of the shaft rides in the seal.

I think its just the cheap calipers I have from harbor freight it seems to be about .20 mm off between the front and back side of the measuring forks. The shafts fit into the bearings as far as they can so they are smaller than the id of the bearings. The 25mm part thats larger on the driveshaft does fit into the oil seal like it should but it hits the bearing and doesn't go in any farther. The 15mm side slides into its bearing nicely and all the way too. It has to be this driveshaft its too long to physically fit in the gearbox. I looked at the gear cover for my engine and I can see on the outside some minor differences. It looks like the input shaft threads and the driveshaft threads are different too. So if I'm using these shafts I need to find the right thread nuts too.

This is a better view of what its doing. I noticed an inspection hole in the gear cover side that lets you see the shaft up against the bearing. drive.google.com/folderview?id=0By2rcNqfITkKTXV3eGgyZDNYRFE&usp=sharingAlso where do I find a gear box gasket for this? It seems like the only gaskets I can find are for a shortcase? Thats the gasket I was given in a long case gasket kit in one of the pictures and it clearly isn't the right one. |
