It's only about an hours job to once you have all the parts.


I don't need to crack the case open to replace the pushrod? I had assumed I would for that, even the case wasn't cracked as I had originally suspected.

Nope, just pull it out. A few parts and you should be putting HD's to shame again in no time. :lol:

Let me know if you can use this seal kit. I stole the crank seals out of it but everything else is still there. You will need the large countershaft seal and several of the medium sized seals during replacement of the transmission cover and sprocket cover.

That's great. It has the three seals for the snifter and everything.

Thanks all for the help. I was able to get over to the bike and take a closer look at the damage. As several of you had predicted, it's really just the pushrod, chain guide, and gasket and transmission covers that were damaged, so I'm breathing a heavy sigh of relief. I've found all the parts on ebay, looks like it's going to cost me just about $80.
A somewhat gentle pull of the clutch pushrod didn't take it out, but it is bent and may need some more force behind it.

Nessism, thanks, I could very much use that oil seal kit. I'll PM you.

A #3 phillips bit works fine. Don't scare the man. :S


I've got a philllips impact driver which has on the one hand worked great for phillips screws, but on the other hand stripped out a JIS screw for me. I also have these impact-like screwdrivers.. see www.amazon.com/Vessel-Megadora-Impacta-P...driver/dp/B003BGZ9CO . They idea is that they are solid screwdrivers, but have the impact driver mechanism built into the handle. Anyone tried one yet? They work great as screwdrivers, but that's all I've used them for.


I have not tried one of those, but any time I see a tool with such a long, overly impressive, made up name, I immediately suspect that there is more marketing than tool.


Just leaving this here for others' reference in the future. They have made good screwdrivers, like I said, but I just dealt with 3 stuck screws, and this Megadora driver's 'impact feature' didn't do anything for them. A standard heavy handheld impact driver loosened each screw up easily.

Nessism wrote: Hard to tell but I agree with Steve, looks like bolt on parts: sprocket cover, transmission cover, and crescent shaped metal chain guard. All replaceable parts.

Oh, and your sprocket is worn out. Add a new chain and sprocket set to the shopping list.

Edit: may also need a clutch pushrod, and of course new seals for the transmission cover. Speaking of that, I've got some spare seals if you find yourself in need. Have to check but should have a full set. PM me if you want to discuss.


I realize you have something of a conflict of interest here, but I'll ask anyway: Do I really need new seals? I have no reason to doubt the old transmission cover's seals, though pulling them might damage them? The replacement cover I've purchased (used, on ebay) also comes with all the seals.

On that topic: Is a new mission cover gasket necessary in these situations? What's the rule with gaskets - get a new one every time you crack the part open? (carbs, crankcase, transmission cover, etc)

The seals and gasket are something like 35 years old. If you want to gamble that's your choice. It's not like you are talking about a bunch of money or anything though.

It's best to replace them. If they aren't broken I use copper high temp silicon. It can still weep sometimes. If the seals are still pliable, they should be good. I wouldn't try to reuse the old ones. If Ness will give them to at a good price, I'd go for it. One less thing to worry about.
