Did you find some old stock, since the boxes still state "Mad in Germany" ?

 

[dustinwilt68]

I am not sure if they are NOS or what, all I know is they are brand new and I got them from Germany, I was lucky to find a contact there and we have done a few transactions now and they have went great.

and what's in that boxes exactly?

My pair of solo twins, I call them that cause they are serial number 1 apart from each other, the other 2 I had here were different serial numbers all together, one of the three that just came was 1 number earlier then the first saw I ordered, so I kept that one for myself.

Reaching out for help to you makita guys. I have a pretty clean 6421. It just quit oiling. Ive checked the drive is ok, the lines are clear. All i can get out of it is just some random spurts every so often, nowhere near enough to oil the chain in the wood. Are the oil pumps prone to failure on these? Do i just need to bite the bullet and buy a new pump and lines. Or is there something else i should check first

 

[Boomer 87]

Also is there a better place other than ereplacement parts to get these pieces. The pump assembly alone is 68 bucks

@dustinwilt68
Are you changing the jug on any of those?

Check Your saws oil pump drive.

No, these saws are not prone to oil pump failures.

Try Nate's shop:

Oil pump repair kit should do the trick if there is any pump defect.

My pump drive is ok, i may just get the rebuild kit and new lines to save me some money, thanks for the reply.

The control bolt is plastic, as well as the nub on the end, and the nub wears off. Out of 20 that I've worked on 3 needed an oiler rebuild

Well i just ordered a rebuild kit along with new oil lines and a new clutch bc some oaf compromised it getting it off. (May have been me lol). Need to modify a sparkplug socket like ive seen in other threads to make that job easier.

Forgot that I lent out my belt sander, had to use this instead.

Plan is to use a 7910 top end on the one.

 

[Lightning Performance]

And...your going to send me the 665 top to hack up when you get around to it, I hope?

 

[dustinwilt68]

Probably just keep it for a spare for the other one, maybe port it differently then the other top end and compare

You're not alone. I've oafed 2 of them. Make the tool fit tight to the hub

An angle grinder with an 80 grit silicon carbide disc is an acceptable substitute

Just saying...
