HD 4 spd mainshaft bearing housing #OEM#35100-36
fits 1936-1979
Ordered VTwin 17-9761
Info says USA made by Motorshop [VTwin]
OD into case is 2.752" ,oversize. .002"..{too tight}
{possible cracked case if installed or removed without heating case.}
ID of bearing race is slightly oversize..002".bearing falls in,moves freely.{too loose}
The bearing should be light press fit in race,or no clearance. {2.750"-2.751" HD spec}
Depth of bearing race should be about .010"- .015" less than bearing width.
This part of the bearing sticking out is captured by the lock plate that holds it.
17-9761 Depth of bearing hole is about .040" too deep.
The large ID & depth allows the bearing & mainshaft to have lots of unwanted endplay.
Should be no endplay,or only the bearing movement.
-------------------------------------------------------------
I sent that back & ordered an Eastern Mfg Co #A-35100-36
These are supposed to be USA made by Eastern.
Same exact POS part that VTwin claims to make.
1st Pic of bad Eastern part,
2nd pic older Vtwin 17-9774 that would work if a
ham-fisted hammer mechanic hadn't beat it to death.
3rd pic is OEM.
Dennis Kirk,Drag Specialties & J&P also sell the same Eastern Mfg POS.
Even the one JIMS machine sells looks like this one.
--------------------------------------------------
VTWIN #17-9774 is about 2.751 OD & light press fit ID & same depth as OEM
These will work,but slightly heat the case to install or remove.
There are about 1,000 of the bad ones out there.
