Different # of teeth on a 6V fly wheel. 6V starter will not mesh with the teeth on a 12V flywheel. Also, most 6V flywheels have a 180mm clutch as opposed to 12V which have a 200mm clutch. Exception: 1500 bus engines came from the factory with a 6V flywheel cut for a 200mm clutch. Since you have a 6V system you have a 6V flywheel with either a 180mm clutch or a 200mm clutch. --- On Sat, 10/29/11, James Dwan <james_dwan_2000@xxxxxxxxx> wrote: From: James Dwan <james_dwan_2000@xxxxxxxxx> Subject: [tcb] Re: James To: "tcb@xxxxxxxxxxxxx" <tcb@xxxxxxxxxxxxx> Date: Saturday, October 29, 2011, 9:46 AM Well I'm off to get some taps. I have never used one before and assumed they were like easy outs which I use often with a drill. Just curious, how is a 6v flywheel different than a 12v flywheel? I imagine I would have a 12v since some mental midget bought and installed a 12v tranny in my 6v Bus.

Evidently I will need to replace the bushing 2 to 3 times a year. I called Rancho and told them that a guy in Ennis put a 12v tranny in a 6v bus and I have been using a paper thin bushing to solve the problem but it obviously disintegrated after less than 6 months. "Oh yeah, they do that." he said, so I will be using your method until I get around to taking the tranny out and taking it to a transmission shop to drill the hole out. I'd rather drill a hole in someone's head down in Ennis but I digress. The only drill I had that fit the tap has 2 speeds. off and fast. I wallowed out the inside of the bushing so i will have to try different sized taps to see if I can get it out. This will probably fix the starting issue since Hammond Bros. declared my starter "good to go" but the staying running issue will be the next thing to figure out.

Here is an easy method to pull the bushing. Get a tap that is the correct size for the bushing; one that will just screw into the ID of the bushing. Start the tap and slowly run the tap through the bushing. Keep going with it. The tap will bottom out on the bell housing. When it does, continue turning. The tap will then begin to push the bushing out. When the tap is free of the housing just pull the tap out and there you have it. I cannot remember which bushing 6V/12V has the smaller/larger ID, but I have a separate set of tools for each to do the whole job. Larger ID I use a 1/4 pipe thread tap to remove the bushing. For the smaller I use a 14mm tap. (Thread cut is irrelevant). To install the new bushing I made a tool for each, the smaller and larger ID bushing. For the small ID bushing tool I took a piece of 3/4" hardwood dowel rod and turned the end down to approximately 10mm diameter (you want it just be a slip fit into the ID of the new bushing) and the step down on the now 10mm end of the dowel is approximately 12 mm long. This allows you to just slip the new bushing on the step down should be the length of the bushing and drive the bushing in place. The shoulder on the dowel where you cut it down will prevent driving the bushing in too far. For the large ID bushing I did the same but the ID for the bushing is about 15mm diameter. I may be off a bit on some of my measurements; and I think those two tap sizes work, but you should get the idea. I haven't used them in a while and am not positive about which is which. But with these two tools you can remove and reinstall a starter bushing in about 5 minutes and you only have to remove the starter. I actually think I could do one complete including removing and reinstalling the starter in under 10 minutes. And of course VW had a special tool for removal of the bushing but I just made my own removal and reinstall tools. If you have any questions call me if you want 936-569-3542 cell. And I also refurbish ambulance steps! --- On Thu, 10/27/11, James Dwan <james_dwan_2000@xxxxxxxxx> wrote: From: James Dwan <james_dwan_2000@xxxxxxxxx> Subject: [tcb] Re: James To: "tcb@xxxxxxxxxxxxx" <tcb@xxxxxxxxxxxxx> Date: Thursday, October 27, 2011, 9:22 PM Nope, still won't start. I timed it with the static method. I am suspecting it was the 12v to 6v bushing. I took the starter out and noticed that the bushing I put in a few months ago appeared to be gone. I grabbed a 12 to 6 volt conversion bushing - or so I thought. Evidently I had a 12 v bushing mixed in with my 12 to 6v bushing drawer and beat it into place. I figured out my mistake when I tried reinstalling the 6v starter. I tried removing it with an easy out but it wouldn't catch. Looks like I'll be dropping the engine on Saturday morning.so I'll beat it out from the other side. I can't diagnose the running problem until I get it started so...
