Anybody using Tolomatic Gearboxes?
Hi Railfans,
I'm interested in using Tolomatic right angle gear boxes on a set of Blomberg trucks.
If anyone is using them I would really appreciate some pictures of how they are set up and any and all advice is appreciated.
Many thanks,
Railroad Rick

Re: Anybody using Tolomatic Gearboxes?
I was told if you're only using 1 per truck you need to extend the drive shaft and make a shaft support to keep the gear box from cocking over and wearing it self out, but if your going to use 4 gear boxes the support is not necessary.

Re: Anybody using Tolomatic Gearboxes?
Richard,
I would recommend using keyed shafting for your axles and drive line. Slide the Tolomatic boxes onto the axles and then feed the drive line through them. Cut slots in the axles and line shafting an use large snap rings to hold the boxes in position.
I would also recommend using a 4 gearboxes on a Geep or an SD. If using and SD, then use a roller chain to drive the middle axle. Using four gearboxes makes the project sooo much easier. No need to have an outboard support bearing.
Keyed shafting is available in 36" lengths, in a lot of fractional sizes. The advantage is that it has a full length keyway already milled into it.

Re: Anybody using Tolomatic Gearboxes?
If someone has a clear picture of SD trucks with Tolomatic gearboxes could that picture be posted here? I'm particually interested in how the drive shaft clears through the center structure of the truck where the middle axle is located.
I've been studying the photos on the Lee Wright web site and unfortunately there isn't a clear shot. I can see that part of the truck is milled away to make clearance for the drive shaft. But I can't tell how much material was removed and what, if anything, was done to ensure the structure wasn't weakend.
Lee's web site is the only one I've found that shows these gear boxes being used on trucks. Does anyone else have another site?
Thanks,
Brian

Re: Anybody using Tolomatic Gearboxes?
Due to the expense of the Tol-o-matic gearboxes, I will only be using one per truck and relying on #40 chain for the other axle. A rub pad takes out the center slack. A bracket to the existing case holes, keeps the box aligned with the center bolster. Yes, keyed shafting is used throughout, one inch in my case. Tractor Supply has u-joints and slip joint parts that can be welded together in the home shop. Mechanical supply houses carry finer U- joints, but be aware, these model engines take a pounding when in use. The trucks are powered from a jack-shaft arrangment, below the frame, and it is really heavy and fairly bulletproof. Any gear reducers and transmission options are above the frame. and pick up the final chain drive to the jackshaft. This of course is hidden in the fuel tank area, that is a hollow pan, and will contain any parts shed in service.

We use 4 of them and chain drive from the Hydrostatic to the driveline behind the fuel tanks. We had to go to a bigger model as we abuse them! You can see part of it hanging down in the pic.

TomC. That is a great shot of what I described. It is one pic worth so many words. Thank you.
