Anyone know if a new, factory EVO crate motor would have torrington bearings or any other modifications / upgrades / corrections? I ask, because my engine was replaced about 400 miles before I bought the bike.

 

What would the cost be from a HD dealer to have the cam replaced and the pushrods upgraded to adjustable ones? As long as we're in there shouldn't we replace the lifers too? I'm fairly proficient at routine maintenance an wear items but this job looks to be over my head. Yup, I'm afraid I'll "F" it up.

 

I would replace the stock INA bearing with a Torrington first chance I got. HD used to use Torrington bearing and switched to the presumably cheaper INA in 1992. ALL Harley's after that time use INA bearings, including factory crate engines. IMO, I would not try to go over 30K miles without replacing it. We also consider Lifters a routine maintenance item as well and replace them at 30K. This doesn't mean they won't go further but if you do lose one, you lose the cam as well. As mentioned by others, if your in there an EV-27 would be a nice upgrade as well.

The INA Bearings are used in the Twin Cams as well. They are the inner Cam bearings and we replace them ASAP also, stock cams or not. The Torrington Bearings can go well over 100K but are not infallible. When should you replace them????? Your guess is as good as mine but if it were my bike, I'd do them at 100K or when I'm in there doing the lifters for the 3rd time (30Kx3=90K)

The INA bearing is a caged bearing. That means the rollers are separated with spacers. This means less rollers for support. The Torrington bearing is a full roller bearing. That means there are a lot more rollers and no spacers. The rollers are also a little longer. All in all the Torrington bearing is far superior, IMO.

 

FYI...My 98 WG had the INA.

 

Thanks but the project is done and it runs better than if I had the dealer do it.

 

I hope so...it had been a while since the post. I figured I'd note what my 98 had for a cam bearing so fellow garage wrenchers would know to check it out for themselves.

 

My '98 also had the INA. There is a very noticable difference in the two bearings.

 

I just bought a 98 Road King with 10k miles. If I wanted to replace this bearing, what other things should I do while I'm there? New pushrods, lifters, & a different cam?

 

Yes...yes...and yes.

However...at 10K miles I wouldn't use the bearing as your excuse for putting in a new cam. I just finished those options last night. Now if only it wasn't SNOWING!!!!

 

If you're not a racer, go with Andrews EV13 cam or similar, best cam for low end and mid-range, which is what a bagger needs. Do NOT replace lifters with stock, they have a rep for failure, same as the inner cam bearing. Aftermarket ones are higher priced but worth it. I had two lifters fail before I got smart. Pushrods are usually replaced with EZ install so you don't have to take apart everything above the heads to pull out the solid stockers.
