I’ll bet that there are a lot of us who have taken on doing a top end service job on our bikes. Also of noteworthiness is that splitting the cases might have seemed just a little bit beyond our scope of work as a can do at home operation, that is until your videos were created. You have given at least me, the confidence to take on all the detail required to do a good job on all of the work I do to my 1991 FLHS. For sure it has taken a bit more time to save up and acquire the correct tools, which you have give perfect examples of why and how to use them correctly, and I followed these tips to the letter. All in all, I simply wanted to thank you for your work, you have passed on the trade with great quality. Can’t wait to see, hear and feel that Evo fire up again.

Hiya Mike! Once again, a great video. I learned to do this from my mentor, Kenny Kortimeir, in the basement of the Shady Rest Hotel in Atlanta Georgia (sidebar; the SR was a 300 suite, 5 floor, flop-house... and I mean a genuine-honest-to-Goddamn flophouse.. just down from Manual's Tavern (a great place to start a Fryday night... once the -25 kicked in ;-)....)...... that was in the '70's. No one ever suspected there was a top secret lower-end shop in the [SR] basement. Anyhoo, when you go to fit up the rollers, could you mention about the rollers coming in 2-ten-thousandths oversizes from '0' to one thousandths oversize... at which time one would simply press in another '0' race. ...... and thus an 'infinite number of rebuilds' are possible..... lending credence to the line that 'Harleys last forever'. The Hard Part --- the part that makes the "latter-day lower-end overhaulers" squint-n-glare at one for even mentioning it, is the very, very tedious effort required to achieve a perfect 'plug-fit' on the pinion shaft. Respectfully, your beard is long enough that I can safely assume that you know what I'm referring to. Few are willing in these times (let alone know how) to accomplish this oh-so-important-part of the overhaul process in the old-timey way. Could you, pretty please, mention it? Rather late in the day to ask, I suppose, but do you take requests; not wanting to start that avalanche rolling in your direction .... but there it is. As for the vids you are putting up.................. they are all posted (linked), discussed and rather well appreciated on the web site of the club I belong to..... HDRCGB (the Harley-Davidson Riders Club of Great Britain)....... in the 'Vintage and Classic Era' portion of the site. As I am not a club officer, I cannot extend an 'Official' invitation to join in the fun (it cost nothing to post as a Guest) so here's an un-official invite..... Come on in....... p.s. wide shoulders not required. Grins to You, Skip

I'm afraid the roller bearings won't last if you skip that job. If you are rebuilding the lower end, this is a very critical part of it. How about paying a shop to do the parts you can't do?

If your lower end is in good shape (by all appearances), don't disturb it. When rebuilding a top end, you "feel" and listen to the lower end by rotating it and checking it by hand. Experience gives the ability to make an "educated guess." Disassembling for no reason? If you're taking it all apart, replace every bearing and prepare every surface.

If you're removing the flywheel assembly (a pair of flywheels), if you reinstall it with the same bearings, should be the same as when you took it apart. Rather sketchy. Those cases would have to line up exactly the same. The wear on the bearing race would have to match the wear on the rollers. All of the "variables" would need to be the same. It's been done. Not my preference. I don't mean to be negative.

Hi, Mike. Please help me. I have a brand new outer and inner rings, they correspond to the dimensions specified in the manual. do I need to do lapping? I just want to install a bearing of the right diameter without lapping. can I do this without lapping?

Mike...how is the inner spacer between the timken races removed? Is there a tool for removing & replacing it?
@pacificmike9501

Normally, it is easily removed when the races are removed. It's kind of standard procedure nowdays to replace the timken bearings, races, and spacers as a complete prefit set. There is also a set of tools from Jim's Machine that clamps to the big spacer and it can be lifted out.

Hey Mike its me again (I'm old due 250yrs old). So, in VW term the line lapping would be like an align bore(only its actually cutting a true bore for the main bearings) and i'm figuring that the gray your looking for would be similar to a lapped valve seat?. If the gray you are looking for is not achieved,do you go to a smaller size i.d,and how difficult is it to get that bearing out.

It's scary to press that bushing (race) out. Use the right tool. Brace it from the back side. To brace it, I went to the hardware store and bought the closest size pipe coupling and machined it smooth on both ends. Then I used the proper tool and hydraulic press and pressed it out, supporting the case very close to the bushing with the pipe coupling. Then I went to sleep. Enough stress for one day.

1. I'm sure the tool is quite expensive. Would it be odd to take the new bearing set including the races and case halfs to a shop have the races pressed out then have them install the new races and barings for you in the case halfs? Do the case halfs ever need to be align board and OD over sized races used?

@@pacificmike9501 Thanks, I just read in the service manual it says "Right side main bearing consists of components that must be selectively fitted and machined to precise tolerances. Refer right side main bearing replacement to a Harley Davidson dealer." They do tell how to change the left side in the manual. Taking care of the right side must be like align honing and/or align bore the main caps and saddles on a V8 block. I found a shop today here in Milwaukee that will do this work, but they said most just have them rebuild the lower end with parts they provide. I did look for one of those lapping tools, but could not locate one. At least I'll know from your video what they are basically going to do.

I haven't lapped it yet (need the tool) but wanted to ask you if you have seen them completely gone and not worth dealing with and pressing out the old and replacing it with new?

I replaced that bushing in the Evo motor in the video. It's a delicate operation and I did it with no one around to film it. Not a big deal. But, it needed to be done. I had the appropriate tooling and made a support piece to support the case from the opposite side. I made the support out of a large pipe coupling. That way, I could support the case close to the bushing I was pressing both in and out.

Everything needs to line up with those cases. The main bearings, the deck surfaces, all this needs to be carefully checked.
