Something I should've mentioned in the other posts: Some sections of the tractor manual use letters to identify the timer's pin-outs, other sections use numbers, and some of the timers have numbers to identify the pins. To avoid confusion, I've used both letters and numbers to identify the...

Hey guys, thanx so much for your interest and comments. Wasn't sure how this would be received, but I knew there were plenty of fix-it-yerself folks on here. DFB, yeah, kinda figured that there were other/different configuratons of glow plug timers out there. Hope this thread helps others...

This is what the NGK S81NL-2 LampTimer PCB looks like: (For the Kubota) This is the NGK S81NL-2 LampTimer circuit schematic: General description: This NGK S81NL-2 LampTimer is functionally similar to the previous NGK S81NL-1, with some big differences: 1. The Printed Circuit Board now...

This is what the NGK S81NL-1 LampTimer PCB looks like: (For the Kubota) This is the NGK S81NL-1 LampTimer circuit schematic: General description: The NGK S81NL-1 LampTimer is quite similar to the previous NGK S81NF-1, with a few differences: 1. The timers R1/C2 are different, a faster...

This is what the NGK S81NF-1 LampTimer PCB looks like: (Please ignore the unsoldered transistor) This is the NGK S81NF-1 LampTimer circuit schematic: General description: The region around transistor Q1 is the timing circuit, defined by charging rate of the resistor/capacitor pair R1 & C2...

Let's see what's going on in here. The boxes are easy to open, just pry off the back. This is where the surprises appear. The printed circuit boards inside the boxes are all different. The board inside my original timer box doesn't even match the model number labeled on the box. This is what...

The replacement timer was going to run me close to $120 from the local dealer. So, I opted to get a couple of the Kubota timers off eBay, for $35. Now I've got 3 timers.

The glow plug indicator lamp on my New Holland TC35 Boomer would occasionally come on, and now it just stays on. According to the helpful threads in this forum, the cause is a faulty glow plug timer unit...

Radiator installed, filled, doesn't leak. Battery mounted, nice and snug. Need to add acid-absorbing mat under it, that's for later. Let's see if I can get a few more years outta this...

The original plan was to remove the battery tray, and do the fixin' and mig-welding in the shop. Unfortunately, the 4 bolts holding the tray plate to the frame are totally frozen. So, wanting to avoid having this project snowball into a major restoration, I decided to leave it be, and weld it...

Well, here's my TC35 battery tray. Corroded, one clamp end completely broken off, the other one weak/bent and fixin' to go. Here's the parts diagram, battery tray is item #10. Costs about $130. Unavailable at this time.

Cleaned-up, painted, ready for reinstall.

Now, the second/reinforcing part of the repair. Cut some 1/2" wide strips of 0.003" shim brass, and clean the brass until shiny. Thoroughly and thinly solder-tin the brass strip. Cut the strip into lengths that will fit over the exposed repaired cores. Using a piece of flat steel, about...

A new radiator, p/n 86402724, costs around $450. Let's see if we can save a few bucks. I attempted a repair using the 'mud-dauber' solder-blob technique, but kept getting pinhole leaks. So, I decided to get a little more serious. Removed the solder blobs, trimmed back cooling fins from the...

Well, my 2001 New Holland Boomer TC35 blew out all its coolant, and needed some fixin'. At 14 years old, I would think that others of this age may be experiencing this same thing. I searched the web, and found a plethora of info here, on TractorByNet. So, I signed-up, and soaked it all in...
