82-88 Case Repair

so I dug through my cases to rebuild my 87 430, lost the crank on it about 8 years ago, took out the piston and head as metal went through the transfers, in case anyone was curious
the reason or question to the thread was as I looked at my spare cases a glaring problem bothered me
most of them have wear, excessive wear to the hole the kicker fits in, so what to do
my brother talked to his machinist, he said he could make a jig to bore and then make and insert a metal sleeve to correct this
here's the problem,,, it ain't cheap!!!
800-1200 to make a jig that could repeat the process flawlessly
180 to bore and insert the repair
my problem is that'e more than I have in my budget
if a lot of people need this done the jigging could be spread out
he guarantees it will be quality and precise, his reputation matches
any thoughts on this

line bore it and put in an Oilite bronze bushing there are guys who do this waaaaaay cheaper

if the hole was worn round that would be fine but it's not
it is bent in the load direction, so boring should be done with a jig of sorts
how do they get proper alignment?
I like the idea of less, but compromise is not acceptable
do you have a link to someones doing this??

I'm sure there is enough good true bore left that you could insert a gauge pin to pick up your zero location.No need to fabricate a jig whats so ever. That's all he is going to do,except he will make a jig plate.Bolt it down and bore a zero location.Then remove plate and bore your boss.Kind of a waste of money,since he already had his zero location.

Rick Horvat has a jig for all husky cases, Not more that 100+/- and you should add a bushing to shift shaft bore also. His jig come in real handy for those that also have the case crack at the rear mounting hole with dowel in it also. From slightly over tightening . Note all old side cases should add a bushing here. Well husky did add them later year s as standard. Helps not to bind the whole kick start gear combos

A jig really also easy to make. You have case holes, dowel holes but the advantage for me sending out work he has a great mag welder out there in Ohio we can use.

And greg please answer PM texts - 5 weeks of going back and forth on your stuff your selling is not good

I will need to find out about this person or shop you referred to as that s a reasonable price, as long as it's very accurate I am interested
FYI sent you a PM

when I say case repair I am referring to the center cases, not the clutch cover
the hole the kicker shaft fits in is not round anymore

The jig plate should be made using an intact left center case and locate on the dowel holes, not screw holes . 3 screws should be used to restrain the plate flat to ensure location of the hole to bush. It can be bored and sleeved in a Bridgeport type machine with the head trammed to the gasket plane with the knee at the height required for the boring.Raising or lowering the knee after tramming will likely move from trammed position somewhat due to parallax. Common fault of knee mills that most are not aware of.

was that english

I have no idea what that means

That is what need to be done and why it will cost money if if you do not have the skills or equipment to do the job. A qualified machinist would understand the entire procedure. For anyone less I provide detailed pictorials with fewer words. BigBill would understand because back in the day we could build almost anything from a pencil sketch on a beer napkin.

But would you be able to post pictures of it.....

I still do not see what everyone sees in need for a jig plate. If it was made from a new left side case and you planned on repairing a whole lot of cases,maybe. The repair is still going to be done in a mill or jig bore.It's not like your going to bolt on a jig plate and do the repair with a hand drill.

I have digital cameras and know how to use them. In case you never saw what I was posting before I had to stop working on them for awhile.

The jig plate has the round hole to tram the location of the non-round hole to be bored. If the hole is repaired without a jig, it will likely be up to .005" out of location

that was my thought, precision instead of regrets

The posting pics comment was a fun lighthearted jab at Bigbil since he doesn't post pis of his projects.

Thanks for the jab. What pics do you want?

My cr250 with the HVA connecting rod?

What else?

I know I could put it on location with out a plate.The plate would just make it easier. I don't think I'm changing anyone's mind on this one.Having the resources to do this repair my self,I hope 2premo gets his cases repaired to his satisfaction for a fair price.

I agree with auto, it can be done just fine without a jig. We're talking about the kick shaft right? Its not like you are talking about a 9000 rpm crankshaft, its a kick shaft.
