K5 case disassembly
« on: April 11, 2007, 09:17:29 PM »
Hello all,

I have a K5 and have begun case disassembly to replace primary chains, seals, and bearings.  I have encountered a problem and require advice from the technical staff.

Under the gear shift plate is a part called the "Gear shift side plate".  In my Honda manual on page 46 figure 3-70, item 3, you see the plate is held on with a hex nut.  My plate is held on with a large Phillips head screw that has been punched at the factory to prevent if from backing out.  The Clymer manual on page 96, fig. 69 shows my installation.  It does not show the punch marks.  Should I drill the marks, much like I would wheel bearing retainers?  The plate is approximately .160 thick and would tolerate a little drilling.  Is there another way to proceed?

Thanks for any advice or constructive criticism.

I tried to post a picture and it keeps divining me an error.  I tried reducing the size of the image without any luck.  I will try again.  The engine is upside down in the photo.

I would think you should be able to drill the marks just like the bearing retainer, but would try to have a "spare" available just in case it gets drilled too far..even if you do - a bit of loctite on the thread when reinstalling should fix it.. :)

Thanks for the reply!  I agree, and will proceed tomorrow.  Found a spare on a engine I have laying under the bench.  I'll post progress as it comes.

Thanks again

I like the sound of that best.  Do you remove it as one complete unit from the inside out?  I have taken lots of pictures of the entire assembly and will continue today.  The springs and various arms are a little intimidating, I must admit.  Remove, bag, label, remove, bag, label, beer! 

Thanks for the advice from everyone!  What an incredible community!

I pulled the drum out without taking that screw off either. Don't think there's a need to do it unless you want to replace that specific plate.

The springs and arms assembly looks intimidating but is fairly easy to get back together. Just by looking at it you'll figure the order of assembly. The hardest part is hooking the first spring.
