Todays Project - What did you do today?

[f350ca]

The piece of aluminum was one of three, I got Willie. About 1 1/4 thick with a couple of shallow pockets machined in one face and the edges having some profiling done, along with what Im guessing were holes for rivets along the edge. Guessing they failed QC on the way through the line, have scrap engraved on them.

Oh how I would love to get my hands on the Honda engineer(s) that came up with that one!  

Is this a sealed or open bearing?  If it's open fill it with molten paraffin, set it up & grind away.  Once finished, remelt the paraffin.

If it's a sealed bearing I don't have any suggestions.

BTW, I've had that feeling many times about engineers who just don't have a clue how to make their designs.

Yep - the amount of times I've wanted to bitch-slap the designer who said "no - the engine will drop out of the car, not into it..."

Double metal shielded so....

Unfortunately those engineers knew EXACTLY what they were doing! They designed the part to use an odd-ball bearing that you can't buy over the counter, to prevent owners and independent repair shops from rebuilding the unit in question. They have the bearings specially made for their use only.

I need to replace the bearing in my cars distributor because after a mere 200K miles it's starting to sound a bit crunchy. Honda will happily sell customers a new distributor housing assembly (# 6) to the tune of $435 retail, but that ain't happenin....  

   

I did manage to find a bearing with a 12,50 ID online late, late last night. Guess I'll give it a good coat of sleeve retaining compound and pray in stays in place.

Willie,
Don't suppose you can turn the shaft down to 12mm?

I feel your pain Willie - I had a Mitsubishi like that...

Actually "I" wished it were that easy Dave. The problem is the bearing is located in the center of the shaft. Turning the shaft down to 12mm would allow me to fit a standard bearing, but then the #1 cylinder position sensor rotor as well as the ignition rotor on the end would no longer fit on the shaft. The bearing and all of the pickup sensor rotors are a press fit on the shaft.

Ahhh, yes.... the good ole days.  

Guess what - it ain't coming out through there!

My mechanic buddy says that an engineer caught his wife in bed with a mechanic, and mechanics have been paying for it ever since.

I didn't think it would be possible - always the case
