WH mower deck spindle-lube

[Jeff_B 10]

Last year I bought a 36" rear-discharge deck, nice shape and works well. I was pleasantly surprised to see that all three spindles have grease fittings (I've only had the 'lubed-for-life' spindles before...ugh). The natural question: how often should I apply grease and how many pumps of grease should I give each time? Apologies in advance if this topic has been covered before. Thanks in advance for sharing your expertise!

A lot of folks here use Lucas Red & Tacky grease.  Lucas green grease is also a good choice.

 

Both of these have good high temperature performance - a desireable property for this application.

I too have wondered how much grease is enough?  2 pumps,6 pumps?  Can you over fill and blow a seal?

Thanks!

  You can push the bottom seal out of the bearing so pump gun slowly.

 

Fwiw- I blow my deck off real good first. I shine a small flash light under my top pulley's and one under my deck too. Pump my gun a few times slowly on each spindle. (Reg size gun)

 I dont pump it hard/fast & stop pumping if any grease is seen oozing from the top/bottom seal, light helps by reflecting off grease.

  Fyi- An empty spindle took almost a 1/4 tube of grease in each one when I rebuilt my deck/spindles, so quite a bit inside one. I filled them with R&T and once full it won't take but a couple pumps every 50 hours if no leaks detected? Most likely 2-3 is all you'll need.

I saw #2 Molly noted within my Deck/spindle break downs fwiw.
