    Default Garrard 401 Motor Re-Build

    Bearings soaked for 48 hours, felt washers soaked for 24 hours time to reassemble.

    To replace the rivets I used M2.5 12mm Stainless Steel Hex Head bolts. This will facilitate easier future servicing and they cost me a grand total of £2.55 (and that's only because I ordered 50), far cheaper than a Garrard Motor Bearing Service Kit.



    Although they don't look it the heads leave adequate clearance the the rotor.



    12mm is the perfect length for the motor housing and can be used on the top housing without fouling the Eddy disc (I forgot to take a photograph of the top ).



    Although a visual inspection did not show any wear to the ball bearing rolling it on a flat surface it came to an abrupt stop. I dabbed the top with a dry wipe marker rolled it again (and again and again) and the mark was consistently at the top. I wiped the ball bearing and dropped it into the oil bath with the other parts (really just to insure I didn't loose it) and when it was time for reassemble I rolled the bearing, it stopped and I set the bearing down on top of it insuring the flat stop was at the bottom and the rotor would be sat on a fresh face.

    I'l monitor the nuts over the coming weeks and if they're working loose I'll add some thread lock.

    A very simple satisfying job, total cost including 2 new felt washer £10.53.

    Good job i just be a bit worried about motor vibration un loosening those nuts in the long term!

    What about some Loctite '243' Thread-locking fluid in addition! or some nyloc nuts

    Thank you. It has crossed my mind too, I've got the other motor to service now so I'll order some Nyloc nuts too, thanks for the suggestion.

    Thanks for the tip .

    Hi Brian,

    Glad it's helpful and welcome to AoS. What condition is your 401 / plinth / arm etc... and what do you plan on doing to it?

    Default 634 Days Later.

    Now I'm getting into my music listening season i.e. unexpected downtime due to the weather, today I've inspected and serviced the 401 for the first time since the big clean and service on 22/02/2015. I'm very pleased with what I've found, there is no discernible play in any of the nuts and bolts (I never did get round to thread locking them ) no obvious wear and the felt pads are still saturated.





    The 401 has not seen 634 days of continuous use, in fact it's seen very little action for the past few months but none the less it's provided many hours of entertainment in that time. It celebrated it's 50th Birthday this year and with a little oil and a couple of felt pads I don't see why it won't see 50 more, Viva la 401!

    Darren, nice to see you posting again. I hope the 401 gets some usage of Xmas!! I'm still messing around with the 301 when I get time.
