Gear or Motor oil for pilot bushing?
Posted by: Jamison82 ()
Date: October 22, 2017 10:26AM

I just learned the hard way not to pack the pilot bushing with bearing grease. Also not to use the clutch and give it gas to stay in one position on the hill or at a red light. This may be a stupid question but could somebody tell me whether I used gear or motor oil to prep the pilot bushing this time around?

Porous bronze bushing Motor oil squeezed with fingers on ends until oil seeps out of bushing.

Thanks Matt.

Could I use 30 weight motor oil (Amsoil synthetic) or something else?

Most of these types bearings will do better with NON detergent if you have it. Electric motor bearing oil straight 20 or 30. I tried synthetic the last time. No problems at all so far, time will tell.

Just remember: gear oil and brass/bronze do not go together when you can avoid it. So motor oil.

And never hold a car on an incline with the clutch. I've had people burn up a clutch in ONE DAY.

I keep 4 or 5 pilot bushings in reserve. (For my currently broken race car and not yet running street car) I have a small glass jar, an older smaller peanut Butter jar. The bushings are stored in there, submersed in engine oil. I guess they would be ready in a JIF!

I store mine in the little drawer in a carb cleaner plastic cap submbersed in engine oil. When I use one, I move the next one in, sort of the on-deck circle.
I've gotten pilot bushings from different places and not kept track. Some of them fit the shaft okay freestanding but are too tight when installed so I've reamed them out a bit with a sandpaper barrel, not ideal but it hasn't been a problem that I've heard about. I've gotten them from Clarks lately and they've been okay, no reaming needed and I don't think they're magnetic. What's the skinny on pilot bushing materials and availibility these days?

Jim- There are three types of Oilite materials... Oilite, Super Oilight, and
Super Oilight 16. Both Super Oilight and Super Oilite 16 have significant amounts of iron in them to increase harndess, which is desirable for applications that have high pressure loading but low sliding speeds like pivots
for heavy machinery. The original Oilite is an all bronze material with no significant amounts of iron in it (I've read that it can contain up to 1% iron
and still be called "Oilite"). All three types are protected by trademark...
if it says "Oilite" on it, it IS Oilite, if it does not say Oilite, you don't know what it is! The original Oilite is quite a bit softer than the other 2 types and is meant for applications that have a relatively high sliding speeds
and relatively low pressure, like electric motors and

that is normally used to impregnate Oilite bushings is SAE 30 motor oil. "Oilite Plus", which is made from the same type of bronze as the original, is impregnated with turbine oil and particles of Teflon, the addition of the Teflon reduces friction 17%. I would think the best version of
Oilite would be the Oilite Plus type, however, because of the issues surrounding trying to machine this stuff without closing the pores up, it is probably better to buy those as is, OR get some Slick 50 and mix it with SAE 30 motor oil and pre soak the standard Oilite bushing with that.

I always heard it should NON detergent motor oil, maybe it doesn't matter.

So I made what I’m sure is a rookie mistake tonight and smashed then cracked the new pilot bushing. I planned on pressing it with a pulley puller but as you know there are no long bolts available to anchor in the crankshaft. I reluctantly tried tapping it in with a socket and regular hammer...then cane failure and tomorrow I’ll take Uner to work again. (Remember my car is a daily driver)

I don’t have a spare input shaft to use for installation and don’t feel good about using a working part as a tool. Can any of you gents offer some helpful advise?

I’ll order a new bushing from California Corvair’s tomorrow.

The last time I had a Chevelle input gear machined and converted to drive a Yenko gearset, when they cut off the brand-new input shaft, I had them smooth the cutoff and leave a flat surface where the gear was. That left-over steel part has two great tool functions. It is a great clutch disk alignment tool. Perfect for all my 1.125 x 10 discs, Corvair and others. It also acts as a precision installation tool for those pilot bushings. I don't mind tapping on the end of it.

No need for a spare input shaft, just use a block of wood between your hammer a
and the end of the input shaft. Tap, not whack.

Like Seth says, most any GM 10 spline input shaft (most rear wheel drive applications form the 30s on) will work as a tool. Shorter than the Corvair input shaft too. The pilot area is .593" diameter approx.

They usually go in easy. Make sure there is oil on the outside also. They are brass (the non magnetic ones- see discussion above), so tap gently to start, they can bend and break, as you found out.thumbs up

I have a heavy copper hammer and also a big plastic dead blow. Either will work fine and not hurt the input shaft. Make certain it is dead straight before you pound it.

Attempt number two happening tonight. I am going to use the input shaft + wood + hammer to install. Wish me luck.

I have another bushing on it's way in the mail, hopefully I won't need it but it's coming just in case.
