Knock pin : https://www.partzilla.com/product/honda/94302-06100
Knock pin as used on 500/4 I think
MrDavo:
Looks like Honda use those knock pins on all sorts, including jet skis!
I ordered what I need from DS in the end, though they had to split my order as I also need a points shaft oil seal, and they buy those in from Honda, but I don't want to wait for the knockpin.
As I was curious I went to look at my cylinder head at lunchtime, what I thought was a special flat washer to retain the valve guide is in fact the mystery oil seal, it just doesn't look like I expected, ie like a CB750 one / every other valve guide oil seal I've ever seen, well they did say the CB450 was unconventional ;) I ordered them too, £ bloody expensive.
Anyhoo, once I have the knock pin and the rotor puller (dispatched today by the eBay seller) I should be good to get on with assembling the bottom end at last. I got a good used 500T oil pump on Ashley's recommendation from the USA, I'm assuming it will fit straight on.
Basically I want to finish the motor first, so I can store it out of the way, dismantle the (reinforced to take the CB750 engine after it broke :) ) workmate it's on, and use the same bit of garage space to restore the chassis. Only then can I get my Sportster back out of storage (normally it lives where the CL450 rolling chassis is now), if my CB750 stuff isn't back from Menno once spring is sprung I'll need a bike on the road.
What a tangled web we weave.
MrDavo:
It was freezing in the garage last night, I have a little electric heater, which is OK as long as you aren't continually handling things made of very cold metal... However the wife was watching soaps, and that means garage time!
The first job was to get the rotor and starter clutch off with my new puller, which worked fine. As an aside, the puller came from Roger Etcell at Honda Classics in Towcester, so I was a bit confused to find a David Silver Collection brochure (I have a few of these, you may have too) in the envelope, are they related in some way?
Next job was to get the main bearing outer race off without spraying rollers everywhere. I put plastic sheeting under the cases to catch them in case that happened, but hit on the idea of using a zip tie to keep the rollers in their cage, see below.
Note the circlip pliers, I only have about three things made by Snap On, pilfered from work in a previous life, but they are the business. Before I had them, circlips meant time for some godawful butchery involving long nosed pliers and screwdrivers.
Race reversed and in the right place with the oil hole lining up now and the new knockpin installed, starter clutch and rotor back on and torqued up. Time to put the bearing holder in place, oh wait I nearly forgot the camchain. Then I found a snag, the new DID chain from DS was continous, with no soft link. Time to dig out the stupidly cheap camchain splitter / riveter I got from eBay, good job I ordered it well in advance of needing it. Post free though, from China, so why is everything from the US so $$$ to send, even the tinyest item? :o
It came with a full set of instructions. In Chinese, no pictures. >:( Anyway, I worked it out for myself, but I was very wary of buggering up the links either side of the one I took out. It seeemed to go OK, with a bit of trial and error.
Finally, I draped the cut chain over the sprocket, put the bearing carrier over it and torqued up the bolts. Job done, ready to put the cases back together, but next time, it was time to go in and get my hands warm.
JamesH:
Bravo Dave, great work as always - tell you what, it would have been so easy to miss the fact the cage was on the wrong way round & pay the heavy price for no oil feed.
What did the crank builders say when you told them you'd 'caught' their mistake?
AshimotoK0:
Yes great work Dave ... I may get one of those cam chain tools if they are any good. I don't think I will get my crank stripped though..I will probably adopt the 'Jensen' method of flushing.
Roger is ex-Honda UK and set up DS Museum & is also a valuer for Bonhams. He's a nice bloke ...met him at Stafford and the museum.
I wonder if he got permission from Honda to copy and sell their manuals due to his previous employment with them ?
