Just removed engines for refresh. I noticed the bravo couplers, spline looks good, no dry rot and rubber looks good, Do I need change them? They are a bit pricey now.
Thanks

I wouldn't. Just pulling an engine to replace a coupler isn't that bad of a job.

Long as alignment is correct and splines are lubed couplers will last many,many hours.
Did I mention alignment?

Alignment is preset. there is no adjustment. Gil racing mounts. The couplers have been in there since 2003 lol about 900 hrs

Did you remove them yourself or pay someone else to do it? If it were me, and I paid someone to pull/replace the engines, I would replace them. (2 motors/8 hours to R/R x 100.00/hr +) I think you are on borrowed time.

Even though I removed the engines myself and as much as I do not want to spend the $$ on the couplers I agree with you. For the amount of hours on them and the labor hours if one old one fails its better to change them now... It is a big deal pulling an engine for me and the fact that I had to borrow a forklift...I got lucky there!
Thanks for your input

I had one let go at 300hrs. The other one is just fine at 600+ Motors were to come out this year, but now next.

Yea,hate to spend 1k if you don’t have to but 900 is a lot of hrs.

I had one fail on me a while ago, so when I had to pull both engines 2 years ago I replaced the other one just for fun. it was 20yrs old. since the engine was out anyway, took only a few min, and now I know I did everything I could. and to pull it again would be a hassle.

So does anyone have an issue with buying Sierra replacement coupler. $428 shipped. Looks like the same thing??. I don't know how deep $$ I am getting in with the engines so if I can save a few bucks it helps.
