Question: Makita RBC251 Trimmer

cehmtx

Please call me regarding replacement of the "bumper" part OR the entire nylon trimmer head assembly. The price differential for my 12yr old trimmer COULD sway my decision to just trash my Makita and purchase a new one.
Thank you. Craig Heller-Bowling Green, KY - 270-842-9620 (office) or 270-991-1128 (cell).

Hello Craig,

The price of the A-15986 Trimmer Head Bumper, as you know is $6.49. The complete Trimmer Head, part number B-60109 is $39.60. The Makita trimmer has always been one of the best ones out there (My opinion). But it looks as if quite a few of the parts are becoming obsolete. So you can decide on what to do.

Hope this helps,
-WJA

Hello madzack,

Sounds like the gears have finally worn out. You will probably want to replace part number, 6196-30010-06 Gear Case Assembly. They used to sell some of the parts needed for this individually. But it's only available now as an assembly.

Hope this helps,
-WJA

Hello Duke,

If you have a local oil distributor in your area give them the following specs on the grease, the should be able to provide you with another brand if you can't get Shell. But they should be able to cross reference with the Shell number anyway.

Base Oil - Mineral
Thickener - Lithium
Minimum Temp. - -20

Question: Head Removal

Terry Hurst

I have purchased a heavy duty head by Grass Gator and would like to replace the factory head. I can not figure how to get the head off. Most of the tools I have used in the past have a way to lock the head from twisting so it can be unscrewed. I feel ignorant but, just can't figure it out. Please help.

use a small allen wrench and put it through the hole in the gear case into the notch in the cover just behind the trimmer head,then turn head to the right,left hand threads i beleive. this will lock the shaft & the head should turn .
We have two of them and like most over 10 year. Both have taken a lot of abuse. To this day it starts with no more than 5 pulls. The only maintenance the unit has had I am just now doing. Caps and tanks, etc. I would purchase another one if I could, very pleased!

I have had this trimmer for about 10 years. It has been subjected to regular use and has required almost no service. So far I have replaced the gas cap (cracked), the fuel tank (fell out of my truck), and the primer pump (cracked). I also replace the spark plug annually. The unit is very easy to work on, fires right up, and gets the job done. It is light and powerful. I highly recommend.

I bought this string trimmer weed eater over 10 years ago & has been by far the best weed eater I've ever used & have never had a problem with it other then cracked gas cap. Decided to purchase after working for a lawncare service for 4 years. A++

I am a commercial cutter. This has to be the best and the lightest trimmer I have ever purchased.
