Makita 2040 type 1 & 2 diferences - Feed roller adjustment screws

[zafunk [OP]]

I have a Makita 2040 type 1 - with the two part (screw within a screw) feed roller adjustment screws in the top. The screws are pretty chewed up and are a PITA to adjust. Looking at e-replacmentparts.com, they only sell the newer type 2 parts. AFAIK, you can swap out the old system for the new. The question is, do I have to replace all of the components (holder, spring, pin, plane bearing and adjustment screw) or can I just replace the adjustment screw?

Below is a diagram of the type 2 setup:

Sorry to answer my own post but, looking at several different parts suppliers, it would seem that the Metal holder, pin and adjust screw all have to be replaced. It's possible the spring must be replaced too.

It's a pretty expensive changeover, but it doesn't look like anyone carries the old style screws any more.

do you have an actual picture of the chewed up screws?! Maybe someone has seen them on other machines and maybe identify another replacement source.

In the photo, the outside diameter of the larger screw is about 1".

crossing this same bridge myself today.I am having difficulty adjusting one of four.Have you determined if the spring must be replaced also?

Don't order the type 2 parts for your type 1 machine! I just got mine today and they don't seem to be compatible. The top screw doesn't thread into the planer body. I've spent nearly $300- getting these parts and now I find they don't fit! The springs are the same. The towers are slightly different, the old style are threaded inside the top and the new ones are smooth. You could use the old style with the new non-threaded pin. The pressure pin for the spring is different - the old one's threaded, the new one's not.

So now I have a bit of a dilemma, as I have 7 days to RMA the parts at a 25% restocking fee + the shipping - which will probably be $40-. A big chunk of my $300 cost was the $97 in brokerage and duty charged by UPS, even though ToolPartsPro was supposed to ship via USPS. That's a loss. Maybe I could have the top re-tapped to accept the new screws, but it seems risky as the new ones are very close in size and the threading appears to be the same pitch.

Below is a picture of the two different style adjusters.



I had a real hard time getting one of the screws out. I dumped liquid wrench on it and heated the area around it from below to get the oil to penetrate. It worked, but my screws are so chewed up that I'm afraid to put them back in. I can't find replacements for the old style screws anywhere. I'm not sure what to do now.

Ok, now I'm really confused. The kit I just bought is supposed to be a drop in replacement (see photo below).


This page comes from a newer version of the 2040 manual than the one I was working from. So why can't I get the cap screws to go in? At best, I get 1 to 1 turns and then they stop dead. Some of the holes won't start threading at all.

I am sorry to hear of you difficulties. I would suggest measuring the outer diameter of both the new and old screws as well as the pitch of the threads to see if they are the same.They all should be m27. If you are not comfortable or equipped to do that take them to a machine shop and have it done. If they are the same, have the threads in the bore chased wit the correct tap, they may have been damaged when you removed the old adjuster screws. Good luck AL

Hi al.m,

Thanks for the reply.

The only calipers I can lay my hands on ATM are the Lee Valley woodworker's ones. Not super accurate, but if I measure the old adjusters, I get 26.70mm diameter and the new ones measure 26.77mm. The thread pitch is 2mm on both. It looks like the old screws are quite worn, which would account for some of the discrepancy in size.

The new screws came in a ziploc bag loosely packed with other parts. They must have got banged around in transit causing some of the threads to have slight dents in them. I'll have to remedy that too before inserting them.

I have chased threads in bicycle bottom brackets before, but I'm a bit worried about attempting it on my 2040. I think I'll take your advice and seek the help of a machinist.

At least now I know that these are supposed to be a drop in replacement, something I was sure I had read before ordering them, but couldn't find again after I got them.

I cant see or tell from the Pics, which part of the ass. is in need of replacement, can new ones be made? $300 buys a lot of machining. Or can the damage be reworked?

The two Yellow (golden?) colored bits are both very chewed up where you insert tools to set them (see photo in the 4th post). It's a terrible design.

Had I found the manual with the updated parts information before ordering, my cost could have been around $70 for just the cap screws and pins. The $97- in duty and brokerage charged by UPS didn't help either. Live and learn. Hopefully this thread will help others looking to do the same modification to their 2040.

If you want to send it to me , I can see what I can do about reworking it or making some new ones!

So, I finally got the threads chased at a local machine shop. $50 (minimum shop charge), which was cheaper than ordering the M27 X 2 mm tap. Now it works nice and smooth! Also had to file off a few nicks and dents in the threads of the cap screws that probably got "added" during shipping.
