    BF225 - Lower Unit Driveshaft Spline Engagement Issues

    Mystery solved. Driveshaft bushing was just packed with salt on the outside pushing the rubber in right. Guessing two months of drying out made it worse. Pulled the circlip and washer and Lower goes in super easy all the way. I mangled the circlip pretty bad getting it out. Anyone tried...

    BF225 - Lower Unit Driveshaft Spline Engagement Issues

    definitely not that. i can see it's still 1" from engaging. water-tube is harder to see - but i removed water pump to ensure it's not the water-tube binding.

    BF225 - Lower Unit Driveshaft Spline Engagement Issues

    That center-span bushing is a good theory... this is the one with the cir-clip I can access from the bottom? Maybe I'll try taking that out and see if it goes in then. Lower has been off the engine for a few months, is it possible that thing swelled up a bit? From witness marks on the...

    BF225 - Lower Unit Driveshaft Spline Engagement Issues

    So following on from my lower unit saga.... starting with the cracked bearing I finally managed to get all the parts I needed, rebuilt the driveshaft, and rebuilt the propshaft stack into a new propshaft housing, re-assembled - everything looking good. When to install lower back on motor - and...

    BF225 - Tips for removing propshaft holder?

    Drive shaft is out. Snapping that pinion nut free was also a bear. Could not move it with an impact. Had to build a jig to pin case to the floor, keep shaft straight and use a 36” breaker bar on the spline adapter. Now I need to clean my shop so I can put it all back together in a clean-room...

    BF225 - Tips for removing propshaft holder?

    Well … it’s out. Not without sacrifice. Nothing would move this thing. Ended up deciding to accept repaint and so started hitting it hard with propane torch to get case nice and hot. Even then nothing would move. Started air hammering on the tabs assuming I’m sacrificing my bearing carrier at...

    BF225 - Tips for removing propshaft holder?

    I'll try boiling water - but that probably won't be hot enough - feel like I got it into that range with electric heat gun. Maybe I need to torch it and repaint when I'm done. Trying to figure out if there is some way to put a puller on those tabs to get an even pull on them, but a jaw-puller...

    BF225 - Tips for removing propshaft holder?

    will try Aero Kroil. not in a mega rush - local honda shop is backed up and can't look at it for a few months - figured i could probably do it myself sooner.... my efforts with the heat gun were pretty weak - the case is such a huge heatsink that any heat dissipates very quickly. didn't want...

    BF225 - Tips for removing propshaft holder?

    Trying to dig into my lower unit to replace drive shaft bearing. Gear shaft already removed and it’s in fwd gear per the removal procedure. Procedure on 17-19 says to remove the two big bolts then pry the propshaft unit out with screwdriver using the two opposing slots. I’ve broken the tip...

    2004 BF225 25" extension case driveshaft bearing (bushing) question

    This is an awesome thread - thanks for all the details. I'm "staring down the barrel" of my driveshaft trying to understand the complexity of replacing the bearing in this thread and there is a lot of good learnings here. I've been most concerned about lack of tools for the measurement to see if...

    BF225 - cracked bearing?

    I was, but I can see now that's not really possible. I was reading it as two standard roller bearings in opposing directions. Similar to lets say a trailer bearing. From what I see there is a tiny fracture forming on the roller case holder that I suspect is a manufacturing defect - seems like a...

    BF225 - cracked bearing?

    I have the shop manual... but it's quite hard to interpret as it covers full disassembly of the lower unit and assumes a full rebuild; so quickly gets into the weeds of shimming and lash etc. I'm hoping someone here has some experience with doing that and can comment on it a more surgical...

    BF225 - cracked bearing?

    Looking at the bearing part - I might be thinking of this wrong... I was assuming these were two bearings/race stacked on each other, but if the photo is right, it looks like a single assembly - so probably all needs to be pulled out in one, vs replace the top bearing.
