T4 Trooper Timing


Recommended Posts

Hi,  can someone please verify if my timing marks are correct?   

The images are of the timing marks at TDC.  the Crank/Cam marks look right on, but I was surprised to see the cam's timing marks completely off the page.   I was thinking I had it 180 out somehow because that's the symptoms I'm experiencing when trying to start it.   When I'm cranking it, and trying at full throttle, I hear some light (muffled) backfiring that sounds like on the intake side.

      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

      Hello 
      I have a 2022 Massimo t-boss 550. I’m looking for a fix for my timing problem. It keeps getting out of timing. Now I’m trying to find the proper parts for the linhai motor. I’m looking for tensioner chain and gear. If there’s anything else I can do to fix this issue please let me know. Unfortunately I can’t afford to get something better so I got to get it fixed. Thanks in advance.

      I have a Coleman 550 (hisun). Wouldnt start and was sucking instead of blowing through the spark plug hole. Got to the timing chain and it was very loose and for sure the timing was way off. Got the tensioner off and set it to TDC and got the cam gear back aligned. Put the chain back on and set the tensioner as instructed and the chain is still very loose. I extended the tensioner as far as it would go to test and the chain is still loose. 
      Any ideas what could be broken or wrong? Why would the chain be so loose?
