Scored a nice Trackster today! Full cab, roll bars, 137 orig hours. 1500$

Fired up. Little TLC and should go well. After the Tucker should be a piece of cake.

This thing started life in Reading, Mass at a dealer my friend worked for.

even if it looks rough on the out side it looks pretty nice on the inside I like the Polaris atv engine swap some one featured earlier that was a good idea as the omc motors had cooling issues and rarely held together more than 30 hours
 
Hey nice job, I think it was well worth that with cab and roll bar. I have the original motor out of mine it was supposed to be good seems to have good compression just didnt have spark and didn't mess with it. I just put the polaris motor in it instead.
 
the trackster uses a real cool hydrostatic system there are 2 pumps I believe they were sunstrand pumps driven off a ring and pinion spool type set up connected to the engine by a drive shaft and each pump had a direct line to the hydro static motors with a control assembly attached to a t handle. you push forward or pull back to move and twist the handle to go left and right.
 
Got the automatic break lock off so she rolls now. Lost spark since the trailer ride home.

So far I need two coils and I will replace the breaker points. This vintage had a cdi so hopefully that is good.
 
cdi boxes were prone to failure on those riggs there was a kimpex conversion for it you would need to go to the vintage trackster webb site
 
My neighbor and I just picked up 4 of these little machines that had sat for 3-4 years and so far we have 3 that are up and running, the other will be a parts machine. We got rid of the coils and have electronic ignitions, ($250 e-bay). We could use a set of decent tracks for one. So far we are having a ball with them, just waiting for Moose season. All of them have the 29hp OMC 2-stroke engines. We plan on converting to the 28hp Robin-Subaru 4-stroke. Will update you on that after moose season,if all goes well we will convert the other two.
 
I've found it not to be a worthwhile investment... :)

I've only been able to return $$$ spent on parts, few weeks worth of labor ended up going for free... :)

overall, it was a fun little unit...
 
Diving into this project while waiting for more snow. So far got a few belts coming. Need to find flywheel knock off tool, points, coils. Once I can fire it I am sure will need more.
 
Got the flywheel off to replace points. Found the ignition cam has a broken tab. Real nice and clean/new looking.

The manual says it is a high mortality part but replacement seems unavailable.

Any idea where to find one?

I will look through my stuff, I have three or four onan motors from tracksters I've repowered with Hondas
 
Damage comes during the installation of the flywheel. To clean, check, replace points you pop the flywheel off. That piece stays on the shaft. When you reinstall it inserts into the flywheel. If you are not careful it becomes dislodged and when you tighten the flywheel snap. The manual refers to this part as the highest mortality part along with the CD box.

Could have been the people I bought if from or maybe why it sat in the first place.

Praying my network can produce one for me.

I did find one in the parts just let know what you think it worth? Then I will decide whether to hit it with a hammer or send it to you :whistling:
 
Good news maxtrax had one new one left he just emailed me on bought it 59$ I can't sleep when I can't find parts or have something broken. Urgency to resolve that situation always causes me to outbid myself.

Was going to start at 65$ then at your mercy from there. Hold on to that though could break my new one and be back into negotiations!

Thank you all for
The help.

Wow, and I was thinking 20.00 and a beer if we ever met its the darn shipping and handling that adds up :yum:
 
Looks like my automatic sprocket lock has a leak when it retracts under pressure.

Any good source for a seal change? Pretty small piston.

Most people take them off it is the reason many people were hurt on tracksters going down a steep incline if the engine kills the sprocket lock would pop out and you could start to roll the machine it is spring loaded in the out position charge pressure from the hydros pulls it in when the engine is running
