Bolton ZX45 Conversion

[gd.marsh]

Matt,

I got the number out of my G1006/G1007 instruction manual .. it's shown in the break-down of the spindle as number 308 - which is a spacer that goes between the bearings. Pete mentions making one, but for $4.25 I thought I'd take a chance on this one. Can't tell you it's going to be the right length though. If it's too short I'll make an additional spacer to add to it, if it's too long I'll cut it down to the right size. I'm waiting until the parts show up & I get the head all torn down to order the correct bearings.

Thanks Gary - so strange when I look online at G1006+G1007, the part is just not on the head/spindle parts list.. I'll give them a call and see what they have.

Update: had to send them an email after i ordered the other parts (they're working to get all the parts online), but everything is good.

If you're still watching this thread I've got a picture of what the wiring looked like at the motor end on my ZX45 .. it's a little blurry, but the best I've got to offer.


Some Progress ..

The Griizzly parts came in & I got the head torn down .. Notice the oil level .. no kidding! that's the way it shipped. Glad I didn't run if for long. Also it doesn't look like I'm going to use any of the Grizzly stuff after all. I ordered 4 parts from them and only 1 out of the 4 is right. In the mean time I think I can use the shaft that came in the 45 (the one with the red arrow pointing to it) .. a little lathe work, but shouldn't be too bad. I'll post pictures if successful.

Hi Gary,

Funny thing, I order the parts from Grizzly and they tell me the tapered spindle sleeve is on backorder until approx end of May. I ended up cancelling the order. Which part ended up working right?

Matt

The tapered sleeve is the only piece I got that I could use .. the nut they sent me is the wrong thread .. the snap ring & spacer are WAY too big.

After the frustration of receiving parts I can't use, I discovered another problem. The diam. of the tapered sleeve's bearing surface is 10mm larger than the the sleeve on the 45. I did a search and could not come up with a bearing that would fit the tapered sleeve to the 45 head cover as it stands. The best fit I could come up with would require turning the sleeve down 5mm AND boring the cover out an additional 6mm. I'm confident that both are doable w/o jeopardizing the integrity of either part but as I looked more carefully at the existing sleeve .. I realized it could be used with a little modification that could all be done on the lathe. One less set-up = one less chance to error in my book. Pictures to come when it's done.

I have the spindle sleeve from the G3358 which also fits the Bolton spline. I was planning to get bearings locally, but since they are so cheap I went ahead and ordered them and the spacer to see if they will work.

Matt, I don't plan on doing anything with the sleeve before August or so. If you have trouble getting one, let me know and I'll send you this one.

A 45mm ID & 62mm OD does not seem to be a standard bearing as per my searching. If your spindle sleeve or head cover have different dimensions, or if you can find a bearing that would fit w/o breaking the bank I'd sure be interested.

Agreed - less modification, the better. I'm hoping my additional boring/reaming on the axis pulleys goes smoothly.. would hate to ruin those.

Jeff - that's an awesome offer if Grizzly doesn't have the part - which part # is sleeve that you have?

Matt

It's P33581006

Here is a pic of the G3358 spindle sleeve.


Some quick measurements...
Overall length is 140mm
The threaded section is 42mm dia with 1.5mm/turn and 26mm long.
The other end is the only part with the spline, it's 56mm long and takes a 42mm snap ring.

I still have some parts to make for work, so I can't take the head apart just yet. I'll take a look at it this weekend, though.

thank you, I used the manual and got the correct wiring.

The bearings for the 3358 spindle showed up last night, and have a 75mm OD. I guess I'm planning on just making a new steel head cover. That's assuming Pete doesn't come through with a cool conversion kit before I'm ready to do it myself

I also noticed the top of the spindle will end up inside the sleeve and below the top of the pulley which will complicate manually turning the draw bar. It looks like a power draw bar is also in the works <sigh>

Flenser,

I've sent all the parts I ordered back to Grizzly because I've come up with a way to use both the stock spindle sleeve & bearings from the ZX45. I haven't posted any pictures yet but should be able to shortly. I'm still working on my pulleys so when they're done I will post. It involves modifying the spindle sleeve to the point that you couldn't re-use it for a geared setup but I have no plans of doing that anyway. This saves money and solves several issues as far as I'm concerned. Obviously it's untested at this point, but I see no reason to believe it won't work perfectly (might need to change to higher speed rated bearings but I'll wait and see) My intention is to complete the entire belt drive set-up before moving on to the rest of the conversion.
