Harbor Freight 65162 trencher speed upgrade

[@goneredcar1]

The machine out of the box works great, take the time to see all of the videos. They will give you a good idea that it sure beats a shovel and it's fun to use.

[@goneredcar1]

What's great about this press it works and I found that it makes your work look better and goes faster.

[@mrmotofy]

You may want to add the pump info and adapter info to the vid description for easier reference and searches. Thanks for the vid it can help a lot of people.

[@goneredcar1]

It comes with 2.7 Deli pump and a 9 hp engine go with a 4.0 or better max at 4.5 depending on the brand there is no standard. The shaft size 1/2 in. and length is 1 1/2 or better will work and 1/8 keyway. The Salami Pompa mod# 614470242 is a good match at 4.1 watch all the videos to help getting tips and tricks. Good luck and its a great little machine.

[@danspeers9253]

where did you buy the pump?

[@goneredcar1]

The information that is listed in the comment section here has a complete pump describing of the pump. Just search the part number, I found a hydraulic pump supplier in Michigan sorry don’t remember there name. But with the part number you should find something.

[@txsfasano]

I found your KZbin so I upgraded my pump. Works great. Pump Salami Hydraulic Gear Pump 1.6PB4.1D-R080S0 Model # 6142?5002 ( ? looks like 3 or 8 ) I just installed the one above on my backhoe / trencher The "D" is cw (clockwise) when ordering pump.

[@waynepickhardt4975]

Nice upgrade! From what I understand , speed and the inability to use two functions at once was the biggest complaint. Pump volume has everything to do with the speed and performance of the machine. Joystick controls would make it even faster and less robotic. Nice job!

[@goneredcar1]

I measured 16 mm on the adapter when I went to the hydraulic hose place they had them in stock. I remember they were more then the standard conectors. I looked at one of my receipts and it just stated metric conector.

You right if you make move to fast. People tear and hurt them self I've ran backhoes all my life and love playing on them little things

[@goneredcar1]

Get the manual and check for hose placement. You can check the pump by removing the pump output hose from the valve body and place it in the oil tank. Then start the engine and check for oil flow from the output hose.

[@Jrobt29]

Do you know the metric thread pitch on both of the fittings?

[@giovannilemaster1027]

Better watch those pins, that will bend something quick! Nice speed!

[@goneredcar1]

Sorry should have completed the description it’s red and blue tread lock. The detail information is in the text portion of the video. The model number of the pumps are generic and completely describes all aspects of the type pump ( displacement and mounting pattern). Good source of information can be a local hydraulic shop. At first it may be a little overwhelming but as you dig into it , it will make sense.

[@fsilva4ever]

always a pleasure watching your videos what kind of hydraulic oil are you using

[@sipthewater]

I can't tell any difference in mine which is new and that one. Mine is a bit faster. Maybe they upgraded somehow. My cylinder is a bit smaller in diameter but even with weights mine still lifts off of the ground when it rips.

[@goneredcar1]

Sorry pump was obtained local. Read below all pump information is there then search web for a retailer. There are many videos with this subject and read the comments it's all there.

[@Moondoggy1941]

First rule of safety never allow anyone to be within the reach of the swing of the backhoe.

[@stevesmith8767]

Just ordered mine, states it comes with the 9hp predator engine, but would love to upgrade this to something larger. I see that you have upgraded the hydraulic pump, do I need to upgrade any of the lines adapters etc, to get these better performance rates. I know little about hydraulics but I am mechanically inclined around the garage. Im just not sure on the pressure, flow rates pressure tolerances etc in dealing with this stuff. The engine upgrade to something larger would it be worth it, also is there a stater on this to run lights..

[@goneredcar1]

steve smith The way the machine comes with the set hydraulic pressure is pretty much what the machine can handle safely. But with the lines mine came with 1/4” and a small volume pump mine needed a little speed up. I’m running a Diesel now and I run it slow but with a hi volume pump it took some expeiinient

[@goneredcar1]

Sorry dropped my Pad and post my last message before it was completed. I had tried several combinations and settled on the one I’m using now. It’s a blend of hydraulic speed and low engine RPM. The engine handles it just fine. Good tip keep the machine well greased and I mean well greased. I would also change the hydraulic fluid filter after 20 hrs.to remove the crud in the hydraulic tank, it had a lot of weld material from tank construction.

[@slrs3908]

Could you please explain how it is possible to increase flow and still have the same pressure? Did you use a larger engine?

[@loveoftheoutdoors7767]

The function of a pump is to take fluid from one location and move it to another. This is called flow rate. Pressure is the resistance of this flow by the working mechanism, cylinders in this case. So a higher volume pump will complete the work quicker while maintaining pressure. He said in a comment that the original pump is 2.7 GMP and in the video he said he increased this with the new pump by 40% so he is now running a 3.78 GMP (Gallons Per Minute) so he is able to do the same work as before just 40% faster. Hope this helps.

[@dodgeramsport01]

Because volume and psi is two different things! You can increase one but the other will drop

[@stephaniedindy5377]

i would like to attempt building one of these. Would you mind sharing 1.) what size pump you upgraded to? 2.) what size hydraulic cylinders (bore and travel lengths) I will need? Also if something needs beefed up or modified ( in your opinion) to improve the overall performance. I would greatly appreciate any suggestions and feedback you can offer me. I'm good with welding and fabricating and really think I could make one of these. Thanks

[@goneredcar1]

+David F the information on the pump is in the text section of this video. The building of a trencher would be quite challenging and plans are out there to help with the build. However if you read the text here from other builders they have stated that it cost way more to build then they expected. So do your research before you invest a lot of time into a build.

I like your backhoe and would like to make a fully electric one for my electric garden tractor, and it could be charged by solar, zero pollution Brian Edmond 2hrs cutting approx 2 acres or 8-10 hrs pulling trailer on a charge Converting to battery power is a great idea for a garden tractor I converted one 15yrs ago, I used the 3 separate motor design and it is still cutting grass on a daily basis, it is amazing how it never breaks down and needs almost no maintenance, I renew the batteries every 7 yrs I am just on my 3rd set now, my design will cut up to 2 acres on a 50cent charge there are no belts or pulleys and no oil on the entire tractor, it can pull a trailer for about 8hrs on a charge, because battery run time is the most important aspect of most conversions I paid particular attention to the most efficient design, I used 3 separate small motors one for the drive with electronic speed control and two smaller with a cutter blade mounted on the shaft of each cutter motor ,total amperage when cutting grass is approx 40amps, (2000watts) this design only uses the battery power req to do the job, very little wasted battery power, it uses magnetic breaking of both tractor and cutter blades and automatically applies parking brake when you stop or get off the seat, an amazing tractor. electrictractor.net Location of video#1 on youtube kzbin.info/www/bejne/joqxeoadoqabma8

Very informational, considering a purchase & upgrade as you have done. You strike me as a fellow how has many hours on equipment. I have also seen some of the weak points as you have identified. Do you think a guy could put 1,500 hours on one of these machines? Looking to keep it very busy & do that in 5 months, then buy a new machine every season. Digging gravel bars from a creek, down to 6ft, with a smooth edge bucket volume @ about 0.11 cubic yds. Look forward to your thoughts & comments. Regards,

[@goneredcar1]

Thanks for your kind words. The intent of this machine is for the purpose of trenching not loading. The problem is the lift height and the swing distance plus the overall speed. With myself being retired work load and speed isn't a factor. With my small jobs and small profits I make a little money and have some fun doing it.

[@goneredcar1]

David Carpenter Wonder what kind of problem are you having. The pressure regulator is very bulletproof. The one problem you may have is a volume bottle neck with your increased fluid flow volume . There is a video that addresses that problem. I have well over 600 hrs. On the machine without any issues.

Before I bought the machine someone had broke the adjuster off I believe by trying to turn up the pressure and now I have the new pump I would like to fix this as well

[@davidpritch718]

I got the "Salami Hydraulics Aluminum Gear Pump 1.6PE4.1D-R080S0 - mod# 614470242" at Mason Dynamics, Inc. This was the only place online where I could find anything about this pump...$220.04 tax and shipping. I don't think these people actually stock anything. You order from them and then they order it from a supplier somewhere else. When they get it, they'll ship it to you. They said they'll send me an email when it ships. I ordered on 2/25/2019 and it's now end of day 2/28/2019 and I've heard nothing, so I don't think they've received it from their supplier yet. I probably won't get it until sometime during the week 3-11-2019 and 3-15-2019, but who knows.

[@goneredcar1]

Please keep us informed on the upgrade

[@davidpritch718]

Got the pump, but I'm dead in the water because...well, it's crazy. The backhoe uses metric and local hydraulic shops only use SAE. The Salami pump is made in Italy and they use UNF, which I think may be the same as SAE, but I'm not sure, but the output fitting size on this pump is 9/16". Why in the world...what's wrong with 1/2" or 5/8"? Try to get a hose locally with a straight female DIN 16mm 1.5 thread fitting on one end and a 90 degree female DIN 9/16" fitting on the other end isn't going to happen. So you have to get a 9/16" fitting for the pump and then a 9/16" to something else adapter to fit a hose fitting. Go online to buy a hose and there are dozens or hundreds of different types of hose fittings and try to determine what you need using their language and codes. Prepare to spend a ton of time online trying to chase down parts and even then you'll have to "shade tree engineer" something and hope it doesn't break and shower you with scorching hot hydraulic fluid. I can read the tea leaves, so I'm probably going to shelf the Salami pump, take the engine off the backhoe, take it to hydraulic shop somewhere and let them install a pump, mount, coupler connector and install the fittings. Eventually I'm going to have a traditional backhoe valve body installed and have all the hoses and cylinders replaced with all SAE stuff. I'll have a small fortune invested in this backhoe when I'm done, but it'll still be less than what a real backhoe or tractor/backhoe would cost.

[@goneredcar1]

When I refitted the pump I took the old hose that went to the control valve to a hydraulic shop they match the hose fitting adapter to the pump. Then the same to the low pressure side of the pump and hose. I was in and out in no time. The whole job was under 1 hr to complete. I believe they called it BST thread British Straight thread, not for sure but something like that. Hope this helps.

Great job on your upgrades there. I built my own hoe from a set of online plans and it looked slow on all the videos I watch, so I went with a large volume pump. It digs like a small excavator. Also you need to build you a thumb to go on that machine, it come in real handy.

[@johnhemm9313]

i bought this trencher the hydralic there is slight delay on the up and down mostly just down few second delay in response do i need to bleed it ? is tips ?

[@goneredcar1]

I would check oil level and remove the spin on filter for metal particles from assembly. This is a open loop system and bleeding isn’t necessary. Then see if your engine is running fast enough. Remember the pump is very small with little volume. They do this because of safety, because of the group that will be operating them . I have put several hundred hours on my machine and it still looks like new and runs like that to best advise is keep it well greased and oil changed.

Hi I have the standerd machine and it keeps bending the hurdeic cinder rod that comes out on the middle hurdeic cinder the compine has no answer for me do you know why it is dooing this is it bad cinders or to much pressher going to the cinder.?

[@goneredcar1]

I believe your pressure is to high you need to obtaine a pressure gauge and see what your max pressure is running. The relief valve should pop at 2500 lbs or around there. I have heard of several people having that problem if that's the case a simple adjustment is all that's necessary. But remember this should be done by a hydraulic shop.
